Answer:
I think that's Newton's second law of motion
Explanation:
f = m(v-u)
________
t
since a = (v-u)t
f = ma
C
The temperature must go up if the piston remains stationary.
Explanation:
1
.
The temperature must go up if the piston remains stationary
If the piston remains stationary, we know that
Δ
V
, the change in volume of the system, is necessarily zero, i.e.
Δ
V
=
0
.
This implies that the system does no work on the environment as it does not expand.
Answer:
Eventually it reaches bottom of hill so C
Explanation:
Answer:
Part b)
Explanation:
Part a)
As we know that impulse is due to the force applied for small time due to which momentum is changed
so we will have
so we will have
also we know that
now impulse is given as
Part b)
As we know that
It is possible for on object to be going at 100 miles per hour, but still have a velocity. This is because the object going at 100 miles per hour has speed, which is a scalar quantity, which is defined by only magnitude, but the velocity of the object can be 0, since velocity is a vector quantity which is defined by both magnitude and direction.
Since this object only has magnitude and no direction (which is not given), then the velocity can be 0
