Answer:
52 N
Explanation:
Given:
Work done= 1820 J, distance= 35 meters Force = ?
Formula for work done
W = F • d
Find F.
F = W / d
Substitute the given into the equation.
F = 1820 J / 35 m
= 52 N
What I do know is that Copper is a metal that has been deposited from hot sulphur solutions, created in volcanic regions. The hot solutions concentrated the copper up to a thousand times more than would normally be found in rocks. The resultant enriched rocks are called copper ores. I hope this helps.
Answer:
The electrical force between the given charges remains the same.
Explanation:
The expression for the electrical force is as follows as;
Here, k is the constant, are the charges, F is the electrical force and R is the distance between the charges.
It is given in the problem that the magnitudes of the charges and the magnitudes of the separation between the charges are doubled.
Then, the expression of the electrical force becomes as;
Therefore, the electrical force between the given charges remains the same.
Answer:
32500 kg m/s east, 42500 kg m/s west. Second car has larger momentum
Explanation:
The momentum of an object is given by
p = mv
where
m is the mass
v is the velocity
For the first car, m = 500 kg and v = 65 m/s east, so the momentum is
east
For the second car, m = 500 kg and v = 85 m/s west, so the momentum is
west
By comparing the two momentum, we see that the second car has larger momentum.
