Answer:

C. It is the difference in electrical potential energy between two places in an electric field.

Explanation:

The voltage, also known as voltage or potential difference is a physical quantity that drives electrons along a conductor in a closed electrical circuit, causing the flow of an electric current.

The potential difference is also defined as the work per unit of charge exerted by the electric field, on a charged particle, to move it from one place to another. It can be measured with a voltmeter.

In the International System of Units, the potential difference is measured in Volts (V), as is the Potential.

Which is an inertial reference frame (or at least a very good approximation of one)? Which is an inertial reference frame (or at
ioda

Answer:

A jet plane flying straight and at level at constant speed

Explanation:

     The<em> inertial frame </em>of reference is a frame of reference in which all <em>Newton law  is valid</em> ie Newton second law of motion and therefore newton first law of motion holds good. <em>The frame of reference does not accelerate.</em>

All the object that is in the frame of reference are at rest or moving with constant rectilinear motion with constant velocity unless acted upon by any force.

Explain in terms of impulse how padding reduces forces in a collision. State this in terms of a real example, such as the advant
Lena [83]

Answer:

Impulse = Average force x time of contact

Explanation:

Impulsive force is a force which is very large but applied on a body for a very small duration of time.

Impulse is given by the change in momentum of the body.

Impulse = Average force x small time interval

When padding is there, the time interval of contact is large and thus, the force exerted by the body is small.

So, when a person falls on the tile floor, there is no compression and thus, the time of contact is very small and thus the impulsive force is very large, due to  which the body may damage.

So, when a person falls on the carpeted floor, there is a compression and thus, the time of contact is comparatively large and thus the impulsive force is small, due to  which the body may safe.

During the first 50 s a truck traveled at constant speed of 25 m/s. Find the distance that it is traveled.
Allushta [10]
Time=50s
speed=25m/s

Distance = speed×time
=25×50
=1250m

DISTANCE TRAVELLED IS =1250m
