Answer:

Forebrain, Midbrain, and Hindbrain.

Explanation:

Brain is complex structure which is work as control center of the whole body. Brain is helping in receive, send, processes and direct the sensory information. Brain is divided into three key regions with each having different functions.

Forebrain: It is known as the largest part of the brain. Optic cranial nerve and the olfactory are present on the forebrain part. Cerebrum is also the part of the forebrain which cover the 2-3rd part of the brain structure.

Midbrain: It connects the forebrain to the hindbrain. Brainstem which is formed by the composition of Midbrain and Hindbrain, helping to connect the cerebrum with spinal cord. Midbrain helping in to regulate movements and visual signals.

Hindbrain: It is composed of two subregions metencephalon and myelencephalon. It is helping in mentioning of equilibrium and balance, regulation of autonomic functions and coordination in movements.

The force with which I push down on the Earth is PRECISELY equal to the force with which the Earth pushes UP on me.  

I weigh EXACTLY the same amount on the Earth as the Earth weighs on me.  Find THAT amount, and you'll have the answer to the question.

(Hint:  1 kg is a mass, and 2 pounds is a force, so they can never be equal.  1kg weighs about 2.2 pounds IF it happens to be on Earth.  But if the same 1kg is on the Moon, then it weighs about 5.8 ounces.  And if it happens to be on Mars, then it weighs about 13.3 ounces.  The same kilogram weighs different weights in different places.)

On a good day, I push down on the Earth with about 890 Newtons of force.  No matter how hard I try, I can never push more or less than that.

Force is the product of mass and acceleration. The force that an average person pushes down on the earth is about 598 N.

It is defined as the product of the mass and acceleration. It is measured in Newton.

[tex]F= m a[/tex]

Where,

[tex]F[/tex] - force

[tex]m[/tex] - mass = 60 kg

[tex]a[/tex]- acceleration = 9.8 m/s²

Put the values in the formula,

[tex]F= 60 \times 9.8 \\\\F = 598 \rm \ N[/tex]

Therefore, the force that an average person pushes down on the earth is about 598 N.

Answer:

5.09 m/s

Explanation:

Use the height to find the time it takes to land:

y = y₀ + v₀ᵧ t + ½ gt²

0 = 8.0 m + (0 m/s) t + ½ (-9.8 m/s²) t²

t = 1.28 s

Now use the horizontal distance to find the initial velocity.

x = x₀ + v₀ₓ t + ½ at²

6.5 m = 0 m + v₀ (1.28 s) + ½ (0 m/s²) (1.28 s)²

v₀ = 5.09 m/s

The velocity of the projectile the moment it was launched, rounded to the nearest hundredth would be 5.09 m/s.

It can be defined as the motion of any object or body when thrown from the earth's surface and follows any curved path under the effect of the gravitational force of the earth.

As given in the problem, a projectile is launched horizontally from a height of 8.0 m. The projectile travels 6.5 m before hitting the ground.

y = y + v ×t + 1/2 × gt²

0 = 8.0 + v t + 1/2 × -9.8 × t²

t = 1.28 s

x = x + v t + 1/2 at²

6.5 m = v 1.28  + 1/2 × 1.28²

v = 5.09 m/s

Thus, the velocity of the projectile the moment it was launched, rounded to the nearest hundredth, is 5.09 m/s.

Answer:

The purpose of using a chemical reaction is to diagram a reaction, where the left side is formed by reactants and the right side is formed by the product. Through diagraming a reaction, chemists can hypothetically change parts of the both components, that way they would see what to expect in the reaction. Also, they can measure the approximation of amount of mass they would need, and see how components will change after the reaction

Answer:

The amount of Potential Energy lost in the form of Thermal Energy is equal to 41.64 MJ.

Explanation:

mass of the cart and passengers = m = 3.5*10⁴ kg

Height = h = 126.5 m

g = 9.8 ms⁻²

v = 10 ms⁻¹

At the top position the Total energy of the ride is in the form of potential energy given as:

P.E = mgh

= 3.5*10⁴*9.8*126.5

= 43389500 J

At the bottom of the drop, all the Potential Energy will be converted into K.E as the ride develops speed given as:

K.E = 0.5*m*v²

= 0.5*3.5 x 10⁴*100

= 1750000 J

The K.E is much less than the P.E energy even though all the P.E of the ride has been converted. The loss of energy is due to the formation of thermal energy which can be calculated as:

Thermal Energy lost = Total energy in the form of P.E(top) - Total energy in the form of K.E(bottom)

= 43389500 -  1750000

= 41639500 J

= 41.64 M J approx             M J = mega joule = 10⁶ J

[tex]E = 7.45x10^{11} N/C[/tex]

The intensity of the electric field (E) or simply electric field at a point is a vector quantity representing the electric force (F ) that acts over a charge, Q', located at that point.

[tex]E=K\frac{Q}{r^{2}}[/tex], where K is the constant of propotionality, Q a charge, and r the distance between a point and the charge.

[tex]E = 9x10^{9} \frac{Nm^{2} }{C^{2} } \frac{0.0025C}{(0.0055m)^{2}}[/tex]

[tex]E = 7.45x10^{11} N/C[/tex]

The magnitude of the electric field 0.0055 m from a 0.0025 C charge is calculated using Coulomb's law, resulting in an electric field strength of 7.45 x 10¹¹ N/C.

The magnitude of the electric field at a certain point from a point charge. The formula to calculate the electric field (E) due to a point charge (q) at a distance (r) is given by Coulomb's law, E = k x |q| / r₂, where k is Coulomb's constant (8.99 x 109 Nm₂/C₂). For a charge of 0.0025 C at a distance of 0.0055 m, the magnitude of the electric field can be calculated by substituting these values into the formula.

First, substitute the known values into the equation: E = (8.99 x 109) x (0.0025) / (0.00552).
Next, perform the calculation: E = (8.99 x 10⁹) x (0.0025) / (0.00003025), which simplifies to E = 7.45 x 10¹¹ N/C.

This is the magnitude of the electric field at 0.0055 m from a 0.0025 C charge. The electric field strength indicates the force per unit charge that a test charge would experience in the vicinity of the source charge.

A. is correct

Explanation:

Answer:

electrons exist in specified energy levels

Explanation:

In its gold-foil scattering with alpha particles, Rutherford proved that the plum-pudding model of the atom theorised by Thomson was wrong.

From his experiment, Rutherford inferred that the atom actually consists of a very small nucleus, where all the positive charge is concentrated, and the rest of the atom is basically empty, with the electrons (negatively charged) orbiting around the nucleus at very large distance.

However, Rutherford did not specify anything about the orbits of the electrons. Later, Bohr predicted that the electrons actually orbit the nucleus in specific orbits, each orbit corresponding to a specific energy level. Bohr's model found confirmation in the observation of the emission spectrum lines: when an electron in one of the higher energy level jumps down into an orbit with lower energy, the atom emits a photon which has an energy exactly equal to the difference in energy between the two orbits (and this energy of the photon corresponds to a precise wavelength).

A.electrons exist in specified energy levels surrounding the nucleus.

Answer:

The answer is precision.

Answer:

Precision

Explanation:

Accuracy is the measure of how close to the actual value a reading is. Precision refers to the degree of closeness the values are to each other while taking a reading.

For example, if a manufacturer says the length of the table is 50 cm, then if you measure it you should also get 50 cm reading, this shows the reading is accurate. If the reading of the table is taken multiple times then if the values are suppose 49.9, 49.94 etc, then the reading is precise.

Explanation:

In general, the judges in the sports tend to be in charge for correcting and controlling the breaking of the rules in the particular sport. They are allowed to punish the competitors in accordance with the breaking of the rule, or they are there in order to determine weather a point is regular or not. In the rhythmic gymnastics though, and sports similar to it, the judges have different role, as they are in charge of determining the points earned by the competitors. This is done in a manner where every judge gives certain amount of points, or grades, and when those are summed up, the competitors get their total points.

Gravitational field

Explanation:

An object of mass M exerts a force (gravitational force) of attraction on any other object of mass m. The magnitude of this force is

[tex]F=G\frac{Mm}{r^2}[/tex]

where G is the gravitational constant and r the separation between the two objects.

Since the object of mass M exerts this force on any other object located around it, we can think as a "gravitational field", which is the region of space around the object of mass M that exerts a gravitational force on other object. This way, the force exerted on another object of mass m can be rewritten as

F = mg

where

[tex]g=\frac{GM}{r^2}[/tex]

is called strength of the gravitational field.

He did not multiply the chlorine and oxygen atoms by the coefficient 4

Explanation:

Answer:

The correct answer is:

'He did not multiply the chlorine and oxygen atoms by the  coefficient 4'.

Explanation:

Number of atoms in [tex]4 Ca(ClO_3)_2[/tex]

The 4 in front of molecular formula of calcium chlorate is its coefficient . it tells us about the molecules or moles of compound.

Number of calcium in 1 molecule of calcium chlorate = 1

Calcium atoms in 4 molecule of calcium chlorate = 1 × 4 = 4

Number of calcium in 1 molecule of calcium chlorate = 2

Chlorine atoms in 4 molecule of calcium chlorate = 2 × 4 = 8

Number of oxygen in 1 molecule of calcium chlorate = 3 × 2 = 6

Oxygen atoms in 4 molecule of calcium chlorate = 6 × 4 = 24

So, number of atoms of different elements calculated by Carl was wrong as he didn't multiplied the coefficient 4 with chlorine and oxygen atoms.

Answer:

They must be cooler than the air inside the house.

Explanation:

The metal aluminum coils in an air conditioner conduct thermal energy from inside the house and release it outside the house. It is true to say that the coils are cooler than the air inside the house when they are accepting the heat inside the house. Heat will always flow from hot to cold substances

The aluminum coils in an air conditioner act as evaporator coils when accepting heat inside the house, absorbing thermal energy and transferring it outside after the refrigerant is compressed and condenses to a liquid.

When the aluminum coils in an air conditioner are accepting heat inside the house, they are acting as evaporator coils. During this phase, the coils absorb thermal energy from the indoor air. The electrically driven compressor works to raise the temperature and pressure of the refrigerant, causing it to transfer thermal energy and condense into a liquid. This liquid then moves to the outside of the house, where it passes through a pressure-reducing valve into the outdoor evaporator coils. Here, it expands and cools down, releasing the absorbed heat to the outside environment. This process is dictated by the principles of thermodynamics and is a practical application in cooling a home. Air conditioners and refrigerators work based on the same concept, where their efficiency is measured by the amount of heat transfer per work input, often expressed through the coefficient of performance (COP).

When analyzing circuits, wires are treated as perfect conductors, and schematics are used to represent components with standardized symbols and solid lines for connections.

Answer:

[tex]43.2^{\circ}C[/tex]

Explanation:

The change in temperature of the sample of alcohol is given by:

[tex]\Delta T=\frac{Q}{mC_s}[/tex]

where

Q = 890 J is the amount of heat provided to the sample

m = 16.6 g is the mass of the sample

[tex]C_s = 2.47 J/gC[/tex] is the specific heat of alcohol

Solving the equation,

[tex]\Delta T = \frac{890 J}{(16.6 g)(2.47 J/gC)}=21.7^{\circ}C[/tex]

And since the initial temperature was

[tex]T_i = 21.5^{\circ}C[/tex]

the final temperature is

[tex]T_f = T_i + \Delta T=21.5^{\circ}C + 21.7^{\circ}C=43.2^{\circ}C[/tex]
