Answer:bill 5 m/s. Jack:10 m/s
Explanation:
Cuz I took it
It increases, because the centripetal acceleration is inversely proportional to the radius of the curvature.
Hopr it helps :)
Answer:
If one end of a metal bar is heated, the atoms at that end vibrate more than the atoms at the cold end. The vibration spreads along the bar from atom to atom.
Explanation:
The spread of heat in this way is called conduction. Metals are good conductors of heat.
The velocities and the speed build a triangle, where the 1.7 m/s are the hypotenuse and the x-velocity and y-velocity are the other sides.
<span>So the x-velocity is: speed*cos(angle) </span>
<span>now plug in </span>
<span>x=1.7 m/s * cos(18.5)=1.597 m/s </span>
Answer:
true
Explanation:
free fall is said to be the downward movement of an object under the force of gravity only
