Answer:

Explanation: When the electrons move in another direction, they convert this chemical potential energy to electricity in the circuit, thus discharging the battery. So, the battery is all potential energy.

Answer:

because when it is in the electrical state it isn't really doing much. like a battery. it isn't making light, heat, sound, our movement. thus it is potential energy. like a compressed spring its holding energy ready to be used but it is not using it. hope that helped you.

18. A person pulls horizontally with a force of 64 N on a 14-kg box. There is a force of friction between the box and the floor

MA_775_DIABLO [31]

since force=massxacceleration
therefore acceleration=force/mass
the resultant force=the acting force on the object-the frictional force
the resultant force=64-36=28N
therefore the acceleration=28/14=2m/sec^2

How to reduce friction of moving a heavy load .

Vilka [71]

● Use lubricants such as oil.
● Place the load on a piece of cloth as it can ease the friction
● Place the load on a cart with wheels so it can be converted to rolling friction and can be pushed easily.
● Place the load on an inclined plane

A golf ball is struck at 75 m/s at an angle of 60 degrees. What is the

Gnesinka [82]

Answer:

$v_x=37.50$

Explanation:

The rectangular components of a vector $\vec v$ having a magnitude v and angle θ are:

$v_x=v\cos\theta$

$v_y=v\sin\theta$

The golf ball has an initial speed of 75 m/s at an angle of 60 degrees.

The variables of the equations have the values:

v = 75 m/s

θ = 60°

Substituting into the formula:

$v_x=75\cos 60^\circ$

$v_x=75\cdot 0.5$

$v_x=37.5~m/s$

Without specifying units and with precision to the hundredths place:

$\mathbf{v_x=37.50}$
