The increase in the body temperature of pronghorn, the fastest North American animal, results from the chemical energy of the pronghorn converting into kinetic energy with efficiency less than 100%. The remaining energy is converted into heat energy. Thus, raising the temperature of pronghorn.

Due to the chemical energy it gains both kinetic and heat energy.

Help with question 16 and 17

storchak [24]

Your answer is correct.

___

The fractional change in resistance is equal to the given temperature coefficient multiplied by the change in temperature.

R = R₀×(1 + α×ΔT)

R = (10.0 Ω)×(1 + 0.004×(65 -20)) = 11.8 Ω

A person travels by car from Tucson to Phoenix at a constant speed of 75 km/hr. They then return from Phoenix to Tucson at a con

kompoz [17]

Answer:

$v=0$

Explanation:

Knowing that the formula for average velocity is:

$v=\frac{x_{2}-x_{1}}{t_{2}-t_{1}}$

Being said that, we know that the person's displacement is zero because it returns to its starting point

$x_{2}=x_{1}$

That means $x_{2}-x_{1}=0$

$v=\frac{0}{t_{2}-t_{1}}=0$

Reyna kicks a ball, which then rolls across a grassy field. Which is the best explanation for why the ball eventually comes to a

nataly862011 [7]

Short Answer- Friction

Explanation- There is friction between the grass and the ball. Friction is a type of force that limits motion between two surfaces that are touching. Friction is the force that one surface exerts on another with the two surfaces rubbing together.

This is the answer, hope it helps :)
