Answer:

We feel cooler when we spray perfume on our body because the perfume requires latent heat of vaporisation to change its state of matter from liquid to gas and this latent heat is provided by our body. Our body loses heat as it gives its heat in converting perfume from liquid to gas. Hence our body loses heat and becomes cooler.

Hope this helps ;-))

Because the perfume is sprayed as a fine mist. This exposes a lot of its surface area to air, causing it to evaporate quickly. That makes us feel cooler.

Describe the relationship between the potential energy and kinetic energy of an object and the amount of Kinetic energy it can g

ankoles [38]

Kinetic energy of an object is the energy it contains due to movement. If an object is at rest, it doesn't have kinetic energy. If it's moving, then it has kinetic energy. It's pretty simple! The amount of kinetic energy of an object is dependent upon two variables, one being the mass of the object

This scientist focused his study on planetary motion. One of his laws is the planets orbit the Sun in elliptical patterns.

Savatey [412]

I believe that since Kepler focused his studies the rotation of the planets, and the stars, that he is the one who developed the law, which is called the first law of planetary motion.

a father and his son want to play on a seesaw. where on the seesaw should each of them sit to balance the torque

joja [24]

On the opposite sides, the father would out weigh the sons weight, simply because he is bigger than the son

The definite answer is “the opposites side of the seesaw”

the skid marks left by the decelerating jet-powered car the spirit of america were 9600 m long before it came to a stop at 198 m

N76 [4]

Answer:

97 s

Explanation:

Given:

Δx = 9600 m

v₀ = 198 m/s

v = 0 m/s

Find: t

Δx = ½ (v + v₀) t

9600 m = ½ (0 m/s + 198 m/s) t

t = 97 s

Calculate the potential energy of a 1200 kg boulder on a cliff 45 m above the ground.

Softa [21]

Explanation:

Given mass of the object is 1200kg and it's placed at a height of 45m above the ground. As we know that potential energy is ,

$\longrightarrow PE = mgh$

where,

m is the mass of the body .
g is acceleration due to gravity.
h is the height above the ground .

Substituting the respective values ,

$\longrightarrow P.E. = 1200kg * 10m/s^2* 45m$

Multiply ,

$\longrightarrow P.E. = 540000J$

Hence the potential energy is 540000J .

I hope this helps.
