Answer:
c. Velocity
Explanation:
Velocity is a measure of change of position of the body with time. Change of position means the distance traveled by the object in a given interval of time but in a particular direction.
We know that speed is given as the distance traveled over a given time interval without taking into account the direction of motion. So, the magnitude of velocity is same as its speed. Velocity, being a vector quantity, has both magnitude and direction.
Therefore, the <u>velocity</u> of an object consists of its speed and direction.
Gravitational potential energy ...
= (mass) x (acceleration of gravity) x (height)
= (20 kg) x (9.8 m/s²) x (30 m)
= (20 x 9.8 x 30) kg-m²/sec²
= 5,880 joules
The magnitude of the frictional force of the box is 65 N
From the question given above, the following data were obtained:
- Mass (m) = 25 Kg
- Force applied (Fₐ) = 135 N
- Net force (Fₙ) = 70 N
- Frictional force (Fբ) =?
The frictional force acting on the box can be obtained as follow:
Fₙ = Fₐ – Fբ
70 = 135 – Fբ
Collect like terms
70 – 135 = – Fբ
–65 = –Fբ
Multiply through by –1
<h3>Fբ = 65 N</h3>
Thus, the frictional force of the box is 65 N

Answer:
Electric current can be generated by moving a metal wire through a magnetic field.
Answer:
I'm pretty sure it is D:2.
Explanation:
Since potential energy is basically something sitting still. If not C then D.
