Physics
1 answer:
velikii [3]3 years ago
5 0

Answer:

Explanation:

There are two types of collision.

(a) Elastic collision: When there is no loss of energy during the collision, then the collision is said to be elastic collision.

In case of elastic collision, the momentum is conserved, the kinetic energy is conserved and all the forces are conservative in nature.

The momentum of the system before collision = the momentum of system after collision

The kinetic energy of the system before collision = the kinetic energy after the collision

(b) Inelastic collision: When there is some loss of energy during the collision, then the collision is said to be inelastic collision.

In case of inelastic collision, the momentum is conserved, the kinetic energy is not conserved, the total mechanical energy is conserved and all the forces or some of the forces are non conservative in nature.

The momentum of the system before collision = the momentum of system after collision

The total mechanical energy of the system before collision = total mechanical of the system after the collision

A train is traveling north. it goes 200 km /hr for 2.5 hours how far did the train go.
PSYCHO15rus [73]
<h3>Answer: 500 Kilometers</h3>

Explanation:

The formula for finding distance is: speed × time

We must multiply:

200Km/h × 2.5 hours

This gives you 500 Km.

<u>Remember: the formula to work out the distance -  speed x time.</u>

If the train speed is 200 km/h, it travels 200 km/h.

Now, we must multiply 200 by 2.5:

200 x 2.5 = 500

Our answer is 500 Kilometers.

Light with a wavelength of 612 nm incident on a double slit produces a second-order maximum at an angle of 25 degree. What is th
erastova [34]

Answer:

Speration between the slits d=2.86\ \mu m

Explanation:

Given that,

Wavelength of light, \lambda=612\ nm=612\times 10^{-9}\ m

It is incident on a double slit produces a second-order maximum at an angle of 25 degree.

The condition for maxima is given as :

dsin\theta=m\lambda

d = seperation between the slits

m = order, m = 2

d=\dfrac{m\lambda}{sin\theta}

d=\dfrac{2\times 612\times 10^{-9}\ m}{sin(25)}

d = 0.00000289

or

d=2.86\mu m

So, the seperation between the silts is 2.86\ \mu m. Hence, this is the required solution.

A 20 kg box has 1000 joules of potential energy on a shelf. How high is the shelf?
navik [9.2K]
Formula: PE = mgh
m = 20 kg, g = 9.8 m/s^2 h= ?
1000 = 20 * 9.8 * h
1000 = 196h
h = 5.10204082
The height is around 5m
