What is the momentum of a 200 kg truck travelling at 20 m/s?
geniusboy [140]

Answer:

p = 4000 kg-m/s

Explanation:

Given that,

The mass of a truck, m = 200 kg

Speed of the truck, v = 20 m/s

We need to find the momentum of the truck. The formula for momentum is given by :

p = mv

so,

p=200\times 20\\\\p=4000\ kg-m/s

So, the momentum of the truck is equal to 4000 kg-m/s.

What is the thinnest soap film (excluding the case of zero thickness) that appears black when illuminated with light with a wave
Llana [10]

Explanation:

It is given that,

The thinnest soap film appears black when illuminated with light with a wavelength of 535 nm, \lambda=5.35\times 10^{-7}\ m

Refractive index, \mu=1.33

We need to find the thickness of soap film. The soap film appear black means there is an destructive interference. The condition for destructive interference is given by :

2t=m\dfrac{\lambda}{\mu}

t = thickness of film

m = 0,1,2....

\mu = refractive index

t=m\dfrac{\lambda}{2\mu}

t=\dfrac{\lambda}{2\mu}

For thinnest thickness, m = 1

t=1\times \dfrac{5.35\times 10^{-7}\ m}{2\times 1.33}

t=2.01\times 10^{-7}\ m

Hence, this is the required solution.

Please help with this question, step by step<br><br>Thank you!

From the calculation, the force constant is 192 N. Also, friction would decrease the extension.

<h3>What is the force constant?</h3>

We know that the force constant can be obtained by the use of the relation;

F = Ke

F = applied force

K = force constant

e = extension

We know from Hooks law that the force applied is directly proportional to the extension.

We can write;

F = mgcosθ

F = 43 Kg * 9.8 m/s^2 * sin31°

F = 217 N

K = 217 N/1.13 m

K = 192 N/m

If there is friction between the incline and the crate, it will stretch less because some work will be lost due to friction causing only some fraction of the elastic potential energy to be converted to kinetic energy.
