Answer: Third option

F = 250w

Explanation:

The impulse can be written as the product of force for the time interval in which it is applied.

[tex]I = F (t_2-t_1)[/tex]

You can also write impulse I as the change of the linear momentum of the ball

[tex]I = mv_2 -mv_1[/tex]

So:

[tex]F (t_2-t_1) = mv_2 -mv_1[/tex]

We want to find the force applied to the ball. We know that

[tex](t_2-t_1) = 30[/tex] milliseconds = 0.03 seconds

The initial velocity [tex]v_1[/tex] is zero.

The final speed [tex]v_2 = 73.14\ m / s[/tex]

So

[tex]F * 0.03 = 73.14m[/tex]

[tex]F * 0.03 = 73.14m\\\\F=\frac{73.14m}{0.03}\\\\F=2438m[/tex]

We must express the result of the force in terms of the weight of the ball.

We divide the expression between the acceleration of gravity

[tex]g = 9.8\ m / s ^ 2[/tex]

[tex]F=\frac{2438m*g}{g},\ \ m*g=w\\\\g=9.8\ m/s^2\\\\F=\frac{2438w}{9.8}\\\\F=249w[/tex]

The answer is the third option

The average force exerted on the tennis ball during the serve in terms of its weight is closest to 250w, calculated using the equations of motion and Newton's second law.

In this case, the initial velocity is 0 m/s, and the final velocity is 73.14 m/s, with the ball in contact with the racquet for 30 milliseconds (0.03 seconds). The ball's weight w is the product of its mass m and the acceleration due to gravity g (w = mg).

First, we calculate the acceleration a using the equation:

a = (v - u) / t

where v is the final velocity, u is the initial velocity, and t is the time. Substituting the known values, we get:

a = (73.14 m/s - 0 m/s) / 0.03 s = 2438 m/s2

Now, to find the force F exerted on the ball, we use Newton's second law F = ma. However, we want F in terms of the ball's weight w. We know w = mg and F = ma, and by substituting for m from w, we get:

F = (w/g)a

Substituting for a and the acceleration due to gravity (approximately 9.81 m/s2), we find:

F = (w/9.81 m/s2)(2438 m/s2) = 248.72w

Therefore, the average force exerted on the ball in terms of its weight is closest to 250w.

Answer:

A) The absence of fossils of warm-weather plants

Explanation:

During the later stages of the Cretaceous period, the climate started to change. From the predominantly warm, tropical and subtropical, the climate started to have more variations, with mountainous climates starting to develop, as well as temperate climate types. This was caused by the movement of the tectonic plates, as it cause lot of changes in the landscape, positions of the continents, movement of the ocean currents, movement of the air masses. One indicator that the climate cooled down is that the fossils of tropical plants are lacking in most of the planet, and they are only limited to the lowest latitudes, while fossils from plants that are much better suited to temperate climates and colder climate are dominating.

Answer:

The absence of fossils of warm-weather plants might cause them to believe that the Earth grew cooler during this time. Tropical plants would not survive in cold temperatures.

Length contraction causes an object moving at a significant fraction of the speed of light to appear shorter along its direction of motion to an outside observer, and when the object stops, it returns to its original length.

According to the concept of length contraction, the length of an object as it approaches the speed of light, observed by someone in a different rest frame, contracts or shortens in the direction of motion. When the object slows down and eventually comes to a stop, it is observed to expand back to its original length. The correct phenomenon that occurs is that it is observed as contracting and then expanding back to its original length.

The statements ‘Sound insulators prevent sound from being transmitted better than elastic solids' is true of sound transmission through various mediums.

Answer: Option C

Explanation:

The sound insulators are the better way to prevent sound from being transmitted than elastic solids as they have a higher tendency to absorb sound waves than the elastic solids. A good sound insulation is considered in the range of 45 dB.

Mineral wool, rock wool, fibreglass etc are the best to be fit in between the studs of the walls. They absorb the sound waves and help reducing the transmission of sound from the walls, windows, fences, etc.

The molecules become more stiff and move slowly

Answer:

The magnitude of the electric field is 800 N/C and the direction is positive and points to the right.

Explanation:

Ok, here is the explanation:

The magnitude of the electric field is simply defined as the force per charge on the test charge:

[tex]electric field strength=\frac{force}{charge}[/tex]

If the electric field strength is denoted by the symbol E, then the equation can be rewritten in symbolic form as:

[tex]E=\frac{F}{q}[/tex]

and this is the equation we are going to use to solve the problem

We have: E=?, q=+50μC and F=0.040N

We know that 1C=1x10-6 μC so 50μC is equal to 5x10-5 C or 0.00005 C

Then we use the equation as follows:

[tex]E=\frac{0.040}{+0.00005} =800 \frac{N}{C}[/tex]

Because the charge is positive and also the force applied, so will the electric field. And since the force points to the right, the electric field as a vector points to the right.

D. Plane of orbital rotation

Explanation:

The orbital plane of an object orbiting around another is the geometric plane that contains the orbit in question.

By definition, the inclination of a planet in the solar system is the angle between the orbital plane of the solar system and the orbital plane of the Earth.

Final answer:

The plane that all the planets in Earth's solar system must follow is known as the plane of the ecliptic (option A), which is approximately the same plane as Earth's orbit around the Sun.

Explanation:

The plane that all the planets in Earth's solar system must follow is called the plane of the ecliptic. This plane extends through the center of the Sun and the orbit of the Earth. All the planets revolve around the Sun approximately in this plane, and the Earth's axis of rotation is tilted at about 23.5° from being perpendicular to the ecliptic plane. As a result, Earth's rotational axis remains parallel to its previous position as it orbits around the Sun. Conversely, the so-called invariable plane, as discovered by La Place in 1784, is one where the angular momentum vector of the solar system remains constant and is not influenced by the planetary motions. However, for practical purposes, as observed from Earth, the ecliptic is the apparent path of the Sun and planets across the sky.

Answer:

Magneta is a mix of blue and red and is a secondary colour.

Explanation:

As we can see green is the complementary colour of Magneta.Complementary colours are the pairs of colours which when combined cancel each other out. This means that when combined they produce a grayscale colour like white or black .

The complementary colors are opposite on the color wheel, with green being the complement of magenta, yellow the complement of blue, and red the complement of cyan.

The complementary colors on a color wheel are those that are directly opposite to each other. When combined in the additive color system, they produce white light. The complementary color of magenta is green, as magenta is a mixture of blue and red, and green is the opposite of that combination on the color wheel. The complementary color of blue is yellow, which is a mixture of red and green. Lastly, the complementary color of cyan, which is a mixture of blue and green, is red.

Answer:

You will need 7.953 kJ heat energy to raise the temperature of water from 277K to 315K.

Explanation:

To calculate how much heat is needed to raise the temperature of any substance, you need:

The mass of the substance,  m, which for you is 50.0 g

The temperature change that occurs,  ΔT, which for you is:

Δ[tex]T=(315-277)K=38K[/tex]

The specific heat capacity of the substance,  c,

For water, the value of  c  is  4.186J/gK

Then, this is the equation you need:

[tex]Q=mc[/tex]ΔT

Where Q is the heat needed

So,  

[tex]Q=(50.0g)(4.186J/gK)(38K)=7953.4J=7.9534kJ[/tex]

You need 7.953 kJ to raise the temperature of water from 277K to 315K.

The heat required to raise the temperature of 50.0 g of water from 277 K to 315 K is 7964 joules, using the specific heat capacity of water, which is 4.18 J/g°C and the formula Q = mcΔT.

To calculate the amount of heat required to raise the temperature of water, we use the specific heat capacity of water, which is 4.18 J/g°C. The formula we'll use is Q = mcΔT, where Q is the heat energy, m is the mass of the water, c is the specific heat capacity, and ΔT is the change in temperature.

For 50.0 g of water being heated from 277 K to 315 K, the change in temperature (ΔT) is (315 K - 277 K) = 38 K. Since the Kelvin and Celsius scales are offset by a constant but rise at the same rate, an increase of 1 K is equivalent to an increase of 1 °C. Therefore, the heat energy required can be calculated as follows:

Q = mcΔT
Q = (50.0 g) × (4.18 J/g°C) × (38 °C)
Q = 7964 J

Therefore, 7964 joules of heat energy is needed to raise the temperature of 50.0 g of water from 277 K to 315 K.

Answer:

D) The heavier ball will have a higher temperature because the change of temperature is inversely proportional to mass.

Explanation:

As stated in the problem, the amount of heat released by each ball is

[tex]Q=mC_p \Delta T[/tex]

where

m is the mass of the ball

Cp is the specific heat of iron (so, it is equal for both balls)

[tex]\Delta T[/tex] is the change in temperature of each ball

In this problem, we are said that the amount of heat released by the two balls, Q, is the same. Cp is also the same: this means that the product [tex]m\Delta T[/tex] must be the same for the two balls. So, the mass and the change in temperature are inversely proportional: therefore, the heavier ball will have a smaller change in temperature. And since both balls starts from the same temperature, 100 C, this means that the heavier ball will reach a higher temperature than the lighter ball.

Answer:

1- Extrusive igneous rock

2- Intrusive igneous rock

3- Organic sedimentary rocks

4- Clastic sedimentary rocks

5- Chemical sedimentary rock

6- Metamorphic rock

Explanation:

Extrusive igneous rock- This are the igneous rocks that are formed when magma ejects out to the surface and quickly solidifies. Since they comes out to the surface, so they are considered to be extrusive igneous rocks. This type of rocks are comprised of smaller crystals due to the faster rate of cooling. For example, basalt.

Intrusive igneous rock- This are the type of igneous rocks that are formed due to the crystallization of magma at a certain depth. This rocks are made up of coarser crystals due to the slow rate of cooling. For example, granite.

Organic sedimentary rocks- This are the type of sedimentary rocks that are comprised of fossil or organic compound. These fossils are trapped about millions of years back. This type of rocks containing fossils are important for determining the past environment, climate and food habitat of these fossil organisms. For example Limestone.

Clastic sedimentary rocks- This are the sedimentary rocks that are formed from the compaction and lithification of loose sediments or broken rock materials. For example, sandstone.

Chemical sedimentary rock- This are the type of sedimentary rocks that are formed from the minerals (crystals). This minerals are made up of the elements that undergoes dissolution in water. For example, oolitic limestone.

Metamorphic rock- This are the secondary rock, either derived from the igneous, sedimentary or other metamorphic rock. These rocks are formed due to the extreme pressure, temperature condition. They are also known as the secondary rocks. For example, Quartzite.
