I think its d . i hope this helps
Answer:
Mass=3,height=50 and time=15,g=10,P=?
P=mgh/t....which is 3×10×50=1500/15=100Watts
Answer: C) velocity is a vector and requires a direction.
Explanation:
In physics, there are two types of quantities:
- scalars: these are quantities that have only a magnitude
- vectors: there are quantities that have both magnitude and direction
As an example, speed is a scalar while velocity is a vector. Therefore, speed has only a magnitude, while velocity has both magnitude and direction: therefore, the difference between the two quantities is that velocity is a vector and requires a direction, as stated in option C.
the characteristics are to make and element
