Tomtit [17]

Inertia: tendency of an object to resist changes in its velocity. An object at rest has zero velocity - and (in the absence of an unbalanced force) will remain with a zero velocity. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force.

tangare [24]
That depends on the wavelength of the electromagnetic radiation.

-- If the waves are long, then we use them for radio, TV, and cellphones.

-- If the waves are shorter than that, then we use them for GPS in the car.

-- If the waves are shorter than that, then we use them to heat meatloaf
in the microwave oven.

-- If the waves are shorter than that, then they warm us and they
make our plants grow ... like the ones we eat.

-- If the waves are shorter than that, then our eyes use them to see with.

-- If the waves are shorter than that, then they tan our skin.

-- If the waves are shorter than that, then they can cause cancer on

dusya [7]

Answer:

12.5 J

Explanation:

Force, F = 25 N

Distance, d = 0.5 m

The direction of force and the displacement is same.

Work is defined as the product of force in the direction of displacement and the displacement.

Work = Force x displacement x CosФ

Where, Ф be the angle between force and the displacement

Here, Ф = 0°

So, W = 25 x 0.5 x Cos0°

W = 12.5 J
