Answer:
An inelastic collision, in contrast to an elastic collision, is a collision in which kinetic energy is not conserved due to the action of internal friction. In collisions of macroscopic bodies, some kinetic energy is turned into vibrational energy of the atoms, causing a heating effect, and the bodies are deformed.
Explanation:
Answer: A 1:1
Explanation:
They both have a magnitude of 1.6 x 10^-19 C.
The right answer for the question that is being asked and shown above is that:
B.
Property Electromagnet Magnet
Permanent magnet X
Temporary magnet X X
Magnetic field created by aligning domains X
<span>Moving electric charge produces magnetic field X</span>
With arms outstretched,
Moment of inertia is I = 5.0 kg-m².
Rotational speed is ω = (3 rev/s)*(2π rad/rev) = 6π rad/s
The torque required is
T = Iω = (5.0 kg-m²)*(6π rad/s) = 30π
Assume that the same torque drives the rotational motion at a moment of inertia of 2.0 kg-m².
If u = new rotational speed (rad/s), then
T = 2u = 30π
u = 15π rad/s
= (15π rad/s)*(1 rev/2π rad)
= 7.5 rev/s
Answer: 7.5 revolutions per second.
The mathematical definition of work is simply the product
of force and distance. That is:
Work = Force * Distance
Hence the work done here by the engine is:
Work = 65 kN * 75 m
