Answer:

Mechanical advantage is the measure of the force amplification achieved by using a tool , mechanical device or machine . ... So MA = 2 means that for example if you apply 100 N then your machine will multiply that force and generate 200 N..

Explanation:

Hope it helps you..

Your welcome in advance..

Answer:

The number of available energy is $4.820\times10^{45}$

Explanation:

Given that,

Energy $E=4.9\times10^{-4}\ J$

Temperature = 2.7 K

Energy states per unit volume $dE=4\times10^{-5}\ eV$

We need to calculate the number of available energy

Using formula of energy

$N=g(E)dE$

$N=\dfrac{8\pi\times E^2 dE}{(hc)^3}$

Where, h = Planck constant

c = speed of light

E = energy

Put the value into the formula

$N=\dfrac{8\pi\times(4.9\times10^{-4})^2\times4\times10^{-5}\times1.6\times10^{-19}}{(6.67\times10^{-34}\times3\times10^{8})^3}$

$N=4.820\times10^{45}$

Hence, The number of available energy is $4.820\times10^{45}$

A 2.00-kg object traveling east at 20.0 m/s collides with a 3.00-kg object traveling west at 10.0 m/s.

ELEN [110]

Momentum = mass x velocity

Before collision
Momentum 1 = 2 kg x 20 m /s = 40 kg x m/s
Momentum 2 = 3 kg x -10m/s = -30 kg x m/s

After collision
Momentum 1 = 2 kg x -5 m/s = -10 m/s
Momentum 2 = 3 kg x V2 = 3V2

Total momentum before = total momentum after
40 + -30 = -10 + 3V2
V2 = 6.67 m/s

Total kinetic energy before
= (1/2) [ 2 kg * 20 m/s * 2 + 3 kg * ( -10 m/s) *2 ]
= 550 J

Total kinetic energy after
= (1/2) [ 2 kg * ( - 5 m/s) * 2 + 3 kg * 6.67 m/s *2 ]
= 91.73 J

Total kinetic energy lost during collision
=550 J - 91.73 J
= 458.27 J
