Speed of particle B is 2v₀/3 m/s to the left. Particle A and particle B will always have equal speed since they experience equal forces.
<h3>Conservation of energy</h3>
The speed and direction of the particle B is determined by applying the principle of conservation of energy as follows;
K.E₁ + P.E₁ = K.E₂ + P.E₂
At any given position, the speed of particle A and particle B will be equal, since they experience equal force and they have equal masses.
The complete question is below:
Particle A and particle B, each of mass M, move along the x-axis exerting a force on each other. The potential energy of the system of two particles assosicated with the force is given by the equation U=G/r 2, where r is the distance between the two particles and G is a positive constant. At time t=T1 particle A is observed to be traveling with speed 2vo/3 to the left. The speed and direction of motion of particle B is ?

Answer:
wave changes its path from its initial direction so this phenomenon is known as Refraction of wave
Explanation:
When wave travels from one medium to other medium the due to change in the speed of the wave propagation it deviates from its initial path.
The deviation of the wave from its initial path is known as refraction of wave
Here we can see that wave incident on medium 1 with some angle with the boundary
Then it enters into other medium and then travels in other direction
So here wave changes its path from its initial direction so this phenomenon is known as Refraction of wave
Answer:
Part a)
Part b)
Explanation:
Part a) What is the period of these waves?
we know that
Since wave frequency (f) is the number of waves per second, and the period (T) is essentially the number of seconds per wave, the relationship between frequency and period is
we have
Remember that
1 Hz is one cycle (or one wave) per second
so
Part b) What is the wave velocity?
we know that
The speed of a wave (v) is equal to the frequency multiplied by the wavelength
we have
so
the answer is not D ....... the answer is {B} if you got it right give me a 5 stars and a hard
Answer:
the acceleration of the car is 10.8 m/s².
Explanation:
Initial velocity (u) = 0
Final velocity (v) = 108 m/s
time (t) = 10 sec
Acceleration(a) = ?
we know
a = (v-u) / t
= 108 / 10
= 10.8 m/s²
