son4ous [18]

A transfer of charge is actually a gross movement of electrons. Charged objects have a normal or "balanced" state. This state is balanced in a sense of positive charges (protons) and negative charges (electrons). When an object has an excess of deficiency of electrons, it will try to regain its balance by releasing or accepting electrons.

A heat engine exhausts 3 000 J of heat while performing 1 500 J of useful work. What is the efficiency of the engine

amid [387]

efficiency=work output/work input×100

since it exhausts(use up)3000j of heat that's the work input and the 1500j is the work input

efficiency=1500/3000×100

=50%

A 0.111 kg hockey puck moving at 55 m/s is caught by a 80 kg goalie at rest. With what speed does the goalie slide on the (frict

Andrews [41]

Answer: 0.076 m/s

Explanation:

Momentum is conserved:

m v = (m + M) V

(0.111 kg) (55 m/s) = (0.111 kg + 80. kg) V

V = 0.076 m/s

After catching the puck, the goalie slides at 0.076 m/s.

1)what is the definition of moment of inertia?

OLEGan [10]

Answer:

Moment of inertia is the inertia of a rotating body with respect to its rotation. So basically it's the object's resistance to a rotational acceleration. This relates to Newton's first law! What does that exactly mean? Let's check out the explanation.

One formula that it is written in is I= mr $x^{2}$

Explanation:

As Bill Nye says, "Inertia is a property of matter. Objects that are not moving don't move unless they get pushed or pulled. Moving objects keep moving unless they get pushed or pulled. This feature of objects and materials is what we call inertia."
