Answer:

Work done is \frac{3}{2}kx^{2}.

Explanation:

The work done by the spring is the same as the potential energy stored in the spring.

So that,

work done = potential energy = \frac{1}{2} kx^{2}

where k is the spring constant of the material of the spring, and x is the compression.

When the spring is compressed by x;

work done = \frac{1}{2} kx^{2}

When the spring is compressed by 2x;

work done = \frac{1}{2} k(2x)^{2}

                  = \frac{1}{2} k(4x^{2})

                  = 2kx^{2}

Therefore,

The work done the second time more than the first = 2kx^{2} - \frac{1}{2} kx^{2}

                                                                                = \frac{3}{2}kx^{2}

The work done the second time more than the first is \frac{3}{2}kx^{2}.

What current passes through a 1 kW heater with 25 V across it?
Ivan

Answer:The voltage V in volts (V) is equal to the current I in amps (A) times the resistance R in ohms (Ω): V (V) = I (A) × R (Ω) The power P in watts (W) is equal to the voltage V in volts (V) times the current I in amps (A): P (W) = V (V) × I (A) AC Ohm's law calculator.

Which of these is an example of the meaning of inertia in physics
Vladimir79 [104]
The correct option is A.
In physics, inertia has to do with Newton's first law of motion which states that an object will continue in its state of rest or in motion unless it is acted upon by a force. Thus, inertia refers to the tendency of an object to continue its motion in a straight line at constant velocity. In the question given above, the car that its brake failed would have continue moving indefinitely if it did not crash into another car, that is, it will continue in its state of motion.
