Answer:
Total momentum = 16 Kgm/s
Explanation:
Let the momentum of the two balls be A and B respectively.
Momentum A = 16 kgm/s
Momentum B = 0 kgm/s (since the ball is at rest).
Total momentum = A + B
Total momentum = 16 + 0
Total momentum = 16 Kgm/s
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
Answer:
.
Explanation:
Sound waves are caused by vibration ripples in water are caused by disturbance in the molecules
Divide 24 by 12.
24/t = 12
24/12 = t
24/12 = 2
t = 2
Efficiency = (energy that does the job) / (total energy used)
= (45 J) / (120J)
I think you can handle the division.
Answer:
2090 J
Explanation:
the work done to move the cart is equal to the product between the force applied and the distance traveled:
In this case, the force applied is F=209 N, while the distance covered is d=10 m, therefore the work done is
