which type of tool was modified to view outer space
Answer:
telescope
Explanation:
Answer:
Astronomical telescope
Explanation:
A telescope is a device used to observe object that are at distant places. It is comprised of lens or mirrors (convex or concave). Light is allowed to pass through it , producing a reflected or a refracted image. The magnification of an image is directly proportional to the len's or mirror's size. A bigger lens produces a magnified and clear image as it allows more amount of light to enter the lens, whereas a smaller lens will produce a smaller image due to its smaller amount of incident light.
Thus, an astronomical telescope is a tool extensively used to view the outer space.
which statement about magnetic force is false ? a. it is expected over a distance. b. it affects only certain types of matter c. it includes forces of attraction and repulsion d. it act only on materials that are touching a magnet.
d, its act only ob material that are touching a magnet
The false statement about magnetic force is: it act only on materials that are touching a magnet. Hence, option (d) is correct.
What is magnetic force?Electromagnetic force is a result of charge motion, which also produces magnetic force. We know that a moving charge creates a magnetic field around itself. In this situation, the magnetic force can be thought of as a force that results from magnetic fields interacting.
As magnetic force is a field force, it is expected over a distance. In every atoms, electron revolves around nucleus but a certain type of material has non-zero net magnetic momentum. Magnetic field affects only the material with non-zero net magnetic momentum. Same poles of magnets repulse whereas opposite poles of magnets attract. But due to being a field force, it does not act only on materials that are touching a magnet - it acts all material in its surroundings .Hence, option (d) is correct.

what Mathematical formula is used to calculate force?
Answer:
F = m × a
Explanation:
M= Mass
A= Acceleration
F= Force
Final answer:
The main formula for calculating force is F = ma, according to Newton's Second Law of Motion. For forces like gravity and tension, specific adaptations of this principle are applied. Other situations may use formulas derived from the basic principles, depending on the context, such as impulse or material properties.
Explanation:
The mathematical formula most commonly used to calculate force is derived from Newton's Second Law of Motion, which states that force is equal to mass times acceleration (F = ma). When calculating the force of gravity on a mass, the formula F = mg can be used, where 'g' represents the acceleration due to gravity. Additionally, when dealing with the force of tension, it must equal the force of gravity plus any force necessary to accelerate the mass. Note that for the calculation of normal force and tension force, if it is not given, Newton's 2nd Law should be applied.
Relativistic force considers force as the time derivative of momentum. The average force can also be computed using the concept of impulse, where average force equals the force time curve area divided by the time interval. Furthermore, when dealing with specific situations like the force on a cable, the force can be found using the formula F = (Y * A * ΔL) / L, where 'Y' is the Young's modulus of the material, 'A' is the cross-sectional area, 'ΔL' is the change in length, and 'L' is the original length.
Can you complete and EXPLAIN please?????:(
Answer:
Explanation:
Well you have the voltages right, and that is no trivial matter. Each one of the resistors in a parallel circuit sees the same input voltages (in this case 6).
Now I think it would be a good idea to fill in the the resistance column.
R1 = 3 ohms
R2 = 6 ohms
R3 = 2 ohms
The total resistance can be calculated in two ways. I'll get around to doing both of them but I'll do the conventional way first. One hint: the total resistance must be smaller than the smallest resistor. Read that sentence over a couple of times. What it means is that it must be less than 2 ohms in a parallel circuit.
1/r1 + 1/r2 + 1/r3 = 1/rt
1/3 + 1/6 + 1/2 = 1/rt
Change all the denominators to 6ths.
2/6 + 1/6 + 3/6 = 1/rt
(2 + 1 + 3)/6 = 6/6 = 1
rt = 1
====================
So the current I is V/R
V = 6
R = 1
Current = V/R = 6/1 = 6 amps.
====================
The current in each resistor is
I1 = V / R1
I1 = 6/3 = 2 amps
I2 = V/R2
I2 = 6/6 = 1 amp
I3 = 6/2 = 3 amps
The total is I1 + I2 + I3 = 2 + 1 + 3 = 6 amps.
======================
Remember I said there was 2 ways of figuring out the total resistance. I did one of them about. Here's the other.
R = V / It
R = 6 / 6
R = 1 ohm just what you got before.
====================
Power
P = V * I
P1 = 6 * 2 = 12 watts
P2 = 6*1 = 6 watts
P3 = 6*3 = 18 watts
Pt = 36 watts.
Pt can be done by using the voltage * the total current
Pt = 6 volts * 6 amps = 36 watts, just what you would expect.

The outer ear
The inner ear
The middle ear
The cochlea
The outer ear is the part of the ear that takes up the sound waves and funnels them into the canal.
Answer: Option A
Explanation:
The outer ear is a region of the ear that gathers the information and then funnels the sound into the middle ear. The phrase “funnels the sound” means that the waves of sound are converted into vibration.
These vibrations are then changed as the nerve signals by cochlea present in the inner ear. These nerve signals are read by the brain and the information is received.

Urethra, seminiferous tubules, epididymis, vas deferens
Seminiferous tubules, vas deferens, epididymis, urethra
The correct path of sperm cells through the male reproductive system is seminiferous tubules, epididymis, vas deferens, and then the urethra.
Explanation:The correct path of sperm cells through the male reproductive system is from the seminiferous tubules, where they are formed, to the epididymis, where they mature and are stored. From there, during ejaculation, the sperm move through the vas deferens, which is part of the spermatic cord, towards the ejaculatory duct. Finally, the sperm cells travel through the urethra and are expelled from the body. Thus, the complete path is: Seminiferous tubules, Epididymis, Vas deferens, Urethra.

Earth's gravity attempts to change the velocity of all objects on Earth's surface toward _____ at a rate of 9.8 meters per seconds squared.
Answer:
Earth's gravity attempts to change the velocity of all objects on Earth's surface toward the center of the Earth at a rate of 9.8 meters per seconds squared.
Explanation:
Answer:
Earth's gravity attempts to change the velocity of all objects on Earth's surface toward CENTER OF EARTH at a rate of 9.8 meters per seconds squared.
Explanation:
As we know that the gravitational force of Earth is towards the center and it is given by the formula
[tex]F = \frac{GMm}{R^2}[/tex]
this is the force experienced by all the objects near the surface of Earth and this force is towards the center of the Earth
So this is also know as gravity of Earth
Now we know that the acceleration of objects near the surface of Earth is given by the equation
[tex]a = \frac{F}{m}[/tex]
[tex]a = \frac{GM}{R^2}[/tex]
this is also known as acceleration due to gravity and this is of magnitude g = 9.8 m/s/s
so all objects will move towards the center of earth with rate of change in velocity of 9.8 m/s/s

Atoms from which two elements would form ionic bonds?
Ionic bonds are formed between atoms of metals and nonmetals, resulting in the transfer of electrons from the metal to the nonmetal, creating a stable crystalline compound with zero net charge.
Explanation:Atoms from metals and nonmetals would form ionic bonds. Ionic bonds are electrostatic attractions between positively charged ions, or cations, and negatively charged ions, or anions. These attractions lead to the formation of a crystalline lattice in which the compound has a zero net charge. For example, sodium (Na), a metal, will donate its valence electron to chlorine (Cl), a nonmetal, leading to the formation of Na+ and Cl- ions. These ions will then attract each other, forming NaCl, also known as table salt, which exhibits a stable crystalline structure.
Another example is the formation of magnesium oxide (MgO) when magnesium (Mg), a metal with two valence electrons, reacts with oxygen (O2), a nonmetal with six valence electrons. Magnesium will lose two electrons to become Mg2+, while oxygen will gain those electrons to become O2-. The resulting compound is an arrangement of oppositely charged ions held together by the force of their attraction, resulting in MgO's stable ionic crystalline structure.

A) Current is proportionate to the conductance of the circuit and precisely proportional to the voltage applied across the circuit.
B) Current is conversely proportional to the electrical tension of the circuit and corresponds to the resistance across the circuit.
C) Current is inversely proportional to the resistance of the circuit and directly proportional to the voltage applied across the circuit.
D) Current is commensurate to the resistance of the circuit and directly proportional to the electric pressure applied across the circuit.
The current is “inversely proportional to resistance of circuit” and “directly proportional to voltage across the circuit”.
Answer: Option C
Explanation:
The amount of current flowing through the circuit depends upon the resistance and voltage.
Current depends on resistance of the circuit. If there is high potential difference, the current in circuit will be high. The high resistance leads to less current.
Mathematically the relationship between voltage, current, and resistance is given as [tex]V=I \times R[/tex]. This is also stated as Ohms law.

Explanation:
Hope this helps
Integration of stimuli and comparison with memories and previous stimuli leads to specific responses. Behaviors can be instinctual or learned, depending on the influence of the environment.
Explanation:Integration. Stimuli that are received by sensory structures are communicated to the nervous system where that information is processed. This is called integration. Stimuli are compared with, or integrated with, other stimuli, memories of previous stimuli, or the state of a person at a particular time. This leads to the specific response that will be generated. For example, when seeing a baseball pitched to a batter, the trajectory of the ball and its speed will be considered before the batter decides to swing.
Behaviors can result from this integration of stimuli. They can be instinctual or learned. Instinctual behaviors are not influenced by the environment and include mating systems and methods of communication. On the other hand, learned behaviors are influenced by the environment and include imprinting, habituation, conditioning, and cognitive learning.

Answer:Heavy rain,Strong winds,Severe lightening
Heavy rain, strong winds and severe lightning are the events which can cause damage during thunderstorm.
Answer: Option A, D and E
Explanation:
Thunderstorm is term given to occurrence of heavy rains accompanied by high sounds and lightening. As the sound is produced due to lightening, that sound is termed as thunder and the presence of heavy rain is termed as storm.
So both together is termed as thunderstorm. Thunderstorm usually occurs due to increase in moisture, temperature and when the heated air molecules are raised upward. During these thunderstorms, the occurrence of heavy rains, flow of strong winds and severe lightening are well known.
So heavy rains can lead to flash flooding and destruction of homes, strong winds will also lead to damage of objects and lightening may cause forest fire. Thus these three events during thunderstorm causes damage.

Final answer:
The image formed by a plane mirror is virtual, upright, and of the same size as the object.
Explanation:
The image formed by a plane mirror exhibits specific characteristics. First and foremost, the image is virtual, meaning it cannot be projected onto a screen because it appears to be behind the mirror. The image is also upright, which means it has the same orientation as the actual object (it is not inverted). Moreover, the image is of the same size as the object, which differentiates it from images formed by curved mirrors that can be either magnified or diminished.

If the heart malfunctions, all other body systems will be starved of oxygen.
The cardiovascular system provides the body with vital nutrients and oxygen through a complex network, whereby all organs, body systems, and body tissues receive oxygen-rich blood.
Heart is a muscular-type organ that animals and humans possess, which performs the function of pumping blood to the rest of the body.Oxygenated blood flows from the heart through the arteries, which branch into the smaller arterioles until finally dividing into the capillaries.The capillaries pass into the venules, which open into the veins, which become larger in cross section until the blood finally flows back to the heart.In the capillary area, the transfer of oxygen and nutrients from the blood to the tissues can take place and also allows waste products to pass from the tissues into the blood.Therefore, we can conclude that if the heart malfunctions, all other body systems will be starved of oxygen.
