Answer:
-67,500 kgm/s
Explanation:
1300 * 20 + 1100 * (-85) = -67,500 kgm/s
Explanation:
If a metal rod of length L moves with velocity v is moving perpendicular to its length, in a magnetic field B, the induced emf is given by :

The electric field in the conductor is given by :

It is clear that the electric field is independent of the length of the rod. If the length of the rod is doubled, the electric field in the rod remains the same.
Answer:
4.64m/s
Explanation:
We can use the formula [ v = √2gh ] to solve for this problem. We know that g is constant acceleration (9.8), and h is height (1.1).
v = √2(9.8)(1.1)
v ≈ 4.64m/s
Best of Luck!
Darker is warmer C. Black objects.
Answer:
7.40m/s
Explanation:
The masses of the cars with their respective initial velocities are;




Since the two car stuck after collision, they all move with a common velocity in the same direction.
Let the velocity at which the two cars will be moving after collision be V.
From the conservation of momentum, in a closed system, momentum before collision is equal to momentum after collision.
Mathematically,

By substitution, we obtain;



Dividing through by 408, we obtain


Therefore,v=7.40m/s
