Answer:
This is the answer bro hope it will help you
1). Yes. An object can be moving if the net force acting on the object is zero.
A non-zero net force is required to CHANGE the object's motion ... speed it up,
slow it down, or change its direction. But no force is required to keep it moving
at a constant speed in a straight line.
2).a). The motion of the box changes, from not moving to moving.
So the forces acting on it must be unbalanced.
2).b). The motion of the box doesn't change. It goes from not moving
to still not moving. So the forces acting on it must be balanced.
2).c). The motion of the box changes. Its speed decreases.
So the forces acting on it must be unbalanced.
<span>The fact that light travels at 300,000 km/s is a consequence of Energy Conservation
The particle that move with that kind of speed creates energy way faster than the particle that don't. Which means that it would require less effort to produce the energy,</span>
Answer:
The moment of inertia of the wheel is 0.593 kg-m².
Explanation:
Given that,
Force = 82.0 N
Radius r = 0.150 m
Angular speed = 12.8 rev/s
Time = 3.88 s
We need to calculate the torque
Using formula of torque
Now, The angular acceleration
We need to calculate the moment of inertia
Using relation between torque and moment of inertia
Hence, The moment of inertia of the wheel is 0.593 kg-m².
The answer is A.
It will decay to give you Thorium and Helium.
