Answer:

Kinetic energy is the energy of motion. All moving objects have kinetic energy. When an object in motion. it changes its position by moving in a direction up, down, forward, backward.

When an object of weight w is suspended from the center of a massless string?

igomit [66]

I attached a picture of the diagram associated with this question.

Now,
When we check the vertical components of the tension in the rope, we will find that we have two equal components acting upwards.
These two components support the weight and each of them has a value of TcosΘ

The net force acting on the body is zero.
Fnet=Force of tension acting upwards-Force due to weight acting downwards
0 = 2TcosΘ -W
W = 2TcosΘ
T = W / 2cosΘ

g A thin uniform film of oil that can be varied in thickness covers a sheet of glass of refractive index 1.52. The refractive in

Makovka662 [10]

Answer:

The right solution is "84.09 nm".

Explanation:

The given values are:

Refractive index of glass,

= 1.52

Refractive index of oil (n),

= 1.64

Wavelength (λ),

= 555 nm

Now,

The thickness of the film (t) will be:

= $\frac{\lambda}{4n}$

= $\frac{555}{4\times 1.65}$

= $\frac{555}{6.6}$

= $84.09 \ nm$

1. A ball is thrown downward with an initial speed of 22 m/s on Earth. a. What is the acceleration of the ball? b. Calculate the

vitfil [10]

Answer:

Explanation:

The acceleration of the ball would be due to the downward force of gravity, 9.8m/s^2. In order to find the displacement given that interval of time, you have to use the corresponding kinematic formula:

$d=v_it+at^2/2$
