Speed of light is an example of a light medium wave.

Most famous Michelson-Morley (1887) demonstrated that light travels at the same speed regardless of whether it was measured in the direction of the Earth's motion or at right angles to it. When the light travels through a vacuum: It moves from medium to medium (example: air to glass) speed can change depending of the new medium's index of refraction and the "bending" of light is essentially how lenses work.

Normal force, weight, Kinetic friction, and air resistance are a few I think of the top of my head.

The position function of a particle is given by s=2t3−3t2−63t,t⩾0.s=2t3−3t2−63t,t⩾0. where ss is measured in meters and tt in se

Kisachek [45]

Answer:

$t=5.72\ s$

Explanation:

Given:

the displacement as the function of time:

$s=2t^3-3t^2-63t$

here time is in seconds and the displacement in meters.

Now we differentiate this eq. of displacement to get the equation of velocity:

$v=\frac{d}{dt}(s) \\v=6t^2-6t-63$

According to given the velocity is $99\ m.s^{-1}$ at some time:

$99=6t^2-6t-63$

$6t^2-6t-162=0$

$t=5.72\ s$ & is the only time for (t>=0) instances when the particle will have a velocity of $99\ m.s^{-1}$ but in the opposite direction.

The acceleration due to gravity for any object, including 1 washer on the string, is always assumed to be m/s2. The mass of 3 wa

Pachacha [2.7K]

Answer:

The force will increase in proportion to the mass of the objects

Explanation:

The acceleration due to gravity is always the same. It is expressed in meters per second squared or m/s². The figure of 9.81 m/s² is an average value that was taken after calculating the acceleration under different surfaces. In fact, the acceleration differs depending on the shape of the part of the earth in relation to the earth's magnetic field and force.

Thus, if one washer was 20 kg, the acceleration being 9.81 m/s² the weight will be:

F = ma

= $20 * 9.81\\= 196.2 N$

If there are there washers, the weight will be:

F = 3 * 20 * 9.81

= 588.6 N
