Answer:
Acceleration= final velocity - initial velocity / time
= (15 - 0)/ 5
= 3 m/s^2
Force = mass X acceleration
= 2 X 10^3 X 3
= 6 X 10^3 N
Answer:
4m
Explanation:
you divide 20m/s by 5 seconds
Together the crust and upper mantle are called the lithosphere
Answer:
The peak emf in second coil is 1.876 V
Explanation:
Given :
Inductance 
H
The current 
We compare above equation with standard equation,
From above equation we have,
and 
Find the inductive resistance,
The peak emf in second coil is,
V
Therefore, the peak emf in second coil is 1.876 V
Answer:
1143 N at 1.59 m from the left end
Explanation:
For the system to produce equilibrium, the total force and moment must be 0. Since the total weight downward is
481 + 381 + 281 = 1143 N
Therefore the magnitude of the force acting upward to balance this system must be the same of 1143 N
That alone is not enough, we also need the position of the force for the total moment to be 0.
Let x be the length from the this upward force to the left side. And let the left point be the point of reference for moment arm:
481 * 3.32/2 + 381 * 0.8798 + 281*(3.32 - 0.8798) - 1143*x = 0
x = (481*1.66 + 381 * 0.8798 + 281*2.4402)/1143 = 1.59m
