Velocity is the displacement of an object over the amount of time. It is not the same as speed. If an object travels 4 miles forward and then 4 miles back all in one hour, its speed is 8 mph. However, displacement is the difference between the final position and the initial position. So in this case, the average velocity would be 0 because its final and initial positions were the same.
Weight : It is the gravitational attraction force on an object near its surface.
It is always measured in the unit of Newton(N)
it is given by the product of mass and acceleration due to gravity

here we know that mass of the pig is m = 140 kg
also we know that acceleration due to gravity near the surface of earth is approximately g = 9.8 m/s/s
so here we know by above formula


so correct answer will be
<em>D. 1372 N</em>
Answer:
q = 13 C
Explanation:
Given that,
Electric current, I = 20 A
The starter motor runs for 0.65 s before the car engine starts up.
We need to find how much of electric charge passes through the starter motor. Let it is q.
Electric current = electric charge/time

So, 13 C of electric charge passes through the starter motor.
Answer:
(a) I (Moment of inertia)=0.0987 
(b) W(Angular Speed)=2.66 
Explanation:
Given data
m (Monkey mass)= 1.80 kg
d=2.50 m
T (Time Period)=0.940 s
Angle= 0.400 rad
(a) I (Moment of Inertia)=?
(b) W (Angular Speed)=?
For part (a) I (Moment of Inertia)=?
Time Period Formula is given as

After Simplifying we get



For Part (b) Angular Speed
From Kinetic Energy we get

Pontential Energy

KE=PE




The answer is true!! Plants rely on animals to distribute seeds and animals depend on plants for food shade etc.
