Two identical bodies are sliding toward each other on a frictionless surface. One moves at 1 m/s and the other at 2 m/s. They co
mario62 [17]

Answer:

V=\dfrac{3}{2}\ m/s

Explanation:

Two identical bodies are sliding toward each other on a frictionless surface.

Initial speed of body 1, m₁ = 1 m/s

Initial speed of body 2, m₂ = 2 m/s

They collide and stick.

We need to find the speed of the combined mass. Let V is the speed of the combined mass.

Using the conservation of momentum.

m_1u_1+m_2u_2=V(m_1+m_2)

We have, m₁ = m₂ = m

m\times 1+m\times 2=(m+m)V\\\\m+2m=2m\times V\\\\3m=2mV\\\\V=\dfrac{3}{2}\ m/s

So, the speed of the combined mass is \dfrac{3}{2}\ m/s.

In the Compton effect, the wavelength of the scattered photon is __________ the wavelength of the incident photon.
SOVA2 [1]

Answer:

he wavelength is different (greater) than the wavelength of the incident photon

Explanation:

The Compton effect is the scattering of a photon by an electron, this process is analyzed using the conservation of momentum, in which we assume that initially the electron is at rest and after the collision it recedes, therefore the energy of the incident photon decreases and consequently its wavelength changes

To complete the sentence we use the wavelength is different (greater) than the wavelength of the incident photon

Use the table below to calculate the acceleration of the object. Time (s) 0.0 3.0 6.0 9.0 Velocity (m/s) 0.0 1.2 2.4 3.6
antiseptic1488 [7]

explanation

a=average velocity/average time

average velocity=0.0+1.2+2.4+3.6/4

average velocity=7.2/4

average velocity=1.8 m/s

average time=0.0+3.0+6.0+9.0/4

average time=18/4

average time=4.5 s

a= average velocity/average time

a=1.8/4.5

a=0.4 m/s²

An angle marking is like a meter stick marking. The marking of 1.2m on a meter stick only means an object is 1.2m long if the ob
grandymaker [24]

Answer:

The angle of bend = 20°

Explanation:

Since the question describes that the angle marking is similar to the metre stick marking.

The length of the object when it begins at 0 meters on the meter rule

= 1.2 m

The length of the meter stick when it begins at 0.2 m on the meter rule

= 1.0 m

The difference in length of the object based on the markings

= 1.2 - 1.0 = 0.2 m

If the green marking is on 223°, i.e. θ₂ = 223°

and the straight marking is on 253°, i.e.  θ₁ = 253°

The angle of bend =  θ₁ -  θ₂

The angle of bend = 253° - 223°

The angle of bend = 20°
