Answer:
Wave frequency
Explanation:
Wave frequency is the number of waves that pass a fixed point in a given amount of time.
Most likely the baseball because it weighs less therefore with the same force it will go further due to the fact it weighs less it would be easier to apply force and the less it weighs there is also less force acting upon it.
Momentum is a property of a moving object that makes it hard to stop. It equals the object's mass times its velocity.
Answer:
The constant force is 263.55 newtons
Explanation:
There's a rotational version of the Newton's second law that relates the net torque on an object with its angular acceleration by the equation:
(1)
with τ the net torque and α the angular acceleration. It’s interesting to note the similarity of that equation with the well-known equation F=ma. I that is the moment of inertia is like m in the linear case. The magnitude of a torque is defined as
with F the force applied in some point, r the distance of the point respect the axis rotation and θ the angle between the force and the radial vector that points toward the point the force is applied, in our case θ=90 and sinθ=1, then (1):
(2)
Because the applied force is constant the angular acceleration is constant too, and for constant angular acceleration we have that it's equal to the change of angular velocity over a period of time:
It's important to work in radian units so knowing that
(3)
The moment of inertia of a disk is:
(4)
with M the mass of the disk and R its radius, then
using the values (3) and (4) on (2)
(2)
Because the force is applied about the rim of the disk r=R=1.50:
