Answer:
Explanation:
Work done is defined as the product of force and the displacement in the direction of force.
W = F x d x Cos θ
Where, θ be the angle between force and the displacement.
The force of gravity acts downwards and the displacement is in upward, so the angle is 180. cos 180 = -1 , so the work done by the force of gravity is negative.
The force of rope acting in upwards direction and displacement also in upwards direction.
So, the work done is positive
Answer:
The answer to your question is: DNA.
Answer:
0.03 Joules have been converted into other forms of energy as the direct result of the collision.
Explanation:
Let's start studying the conservation of momentum for the system:
Now that we know the speed of the newly created object, we can calculate how the final kinetic energy differs from the initial one:
Then, when we subtract one from the other, we can estimate how much kinetic energy has been converted into other forms of energy in the collision:
0.045 J - 0.015 J = 0.03 J
10 grams of salt is the result
