ΔT= 81°C was the increase in temperature.
<h3>
steps</h3>
As evidenced by energy conservation
To increase its temperature, all of its kinetic energy will be converted to thermal energy.
ΔT
then divide both sides by the object's mass.
ΔT
therefore, a temperature shift is described as
ΔT= 
ΔT= 
/ 2 x 387
ΔT= 81°C
ΔT= 81°C was the increase in temperature.

Answer:
From 0 -4 seconds the acceleration is positive. (The graph is going upwards.)
From 6-10 seconds the acceleration is negative. (The graph is going downwards.)
The form of energy a violin produces is sound.
Answer:
Correct statement will be dragster rounded the curve with constant speed
Explanation:
It is given that his fried says that The dragster rounded the curve with a constant velocity of 100 km/hour
It is a wrong statement because in circular motion velocity will never constant as the direction of speed is always changing
The correct statement will be dragster rounded the curve with a constant speed because speed may be constant in circular motion
Answer:
F = N*μ or F =m*g*μ
Explanation:
The friction force is defined as the product of the normal force by the corresponding friction factor.
When a body is in equilibrium over a horizontal plane its normal force value shall be equal to:
![N = m*g\\where:\\m=mass [kg]\\g=gravity [m/s^2]\\N= normal force [N]](https://tex.z-dn.net/?f=N%20%3D%20m%2Ag%5C%5Cwhere%3A%5C%5Cm%3Dmass%20%5Bkg%5D%5C%5Cg%3Dgravity%20%5Bm%2Fs%5E2%5D%5C%5CN%3D%20normal%20force%20%5BN%5D)
if we simplify this formula more for a balanced body on a horizontal plane, we will have.
