What's the kinetic energy of an object that has a mass of 30 kilograms and moves with a velocity of 20m/s?

icang [17]

Ek = 6KJ.

In physics, the kinetic energy of a body or object is the one that owns due to its movement and is given by the equation $E_{k} = \frac{1}{2} mv^{2}$ , where m is the mass of the object in kilograms and v is the velocity in m/s.

An object that it has a mass of 30 kilograms and moves with a velocity of 20m/s, its kinetic energy is given by:

$E_{k} = \frac{1}{2} (30kg)(20m/s)^{2}=6000J=6KJ$

Two flat glass plates are separated at one end by a wire of diameter 0.20 mm; at the other end they touch. Thus, the air gap bet

stepan [7]

Answer:

668 bright fringes

Explanation:

t = Thickness = 0.2 mm

$\lambda$ = Wavelength = 600 nm

m = Number of fringes

We have the fringe width relation

$2t=\left(m+\frac{1}{2}\right)\lambda\\\Rightarrow m=\dfrac{2t}{\lambda}-\dfrac{1}{2}\\\Rightarrow m=\dfrac{2\times 0.2\times 10^{-3}}{600\times 10^{-9}}-\dfrac{1}{2}\\\Rightarrow m=666.166\approx 667$

So, total number of fringes will be including m = 0 is $1+667=668$
