By
vector addition.
In fact, velocity is a vector, with a magnitude intensity, a direction and a verse, so we can't simply do an algebraic sum of the two (or more velocities).
First we need to decompose each velocity on both x- and y-axis (if we are on a 2D-plane), then we should do the algebraic sum of all the components on the x- axis and of all the components on the y-axis, to find the resultants on x- and y-axis. And finally, the magnitude of the resultant will be given by
where Rx and Rx are the resultants on x- and y-axis. The direction of the resultant will be given by
where
is its direction with respect to the x-axis.
Answer:
true
Explanation:
free fall is said to be the downward movement of an object under the force of gravity only
Explanation:
It is given that,
Total weight of the piston, W = F = 70 N
Area of the piston,
Let P is the pressure exerted on the piston by the gas. The force per unit area is called the pressure exerted pressure of the gas. Mathematically, it is given by :
We know that the atmospheric pressure is given by :
So, the pressure is given by :
Hence, this is the required solution.
Answer:
the change in momentum = Force x change in time
