Car a is heading north with a velocity of 14 m/s. car b is traveling north also, with a velocity of 19 m/s. what is the relative
kicyunya [14]
a.)  Relative velocity = velocity of car B - velocity of car A
                             = 19 - 14
                             = 5 m/s
Hope this cleared your doubt, feel free to ask any question regarding this and have a nice day ahead! :)

A motorist is traveling at 20 m/s. He is 60 m from a stoplight when he sees it turn yellow. Is reaction time, before stepping on
Gnesinka [82]
V₀ = V₁ + 2ax
V₀ = final velocity which is 0 m/s
V₁ = initial velocity which is 20 m/s
x = distance which is 60-(0.5 x 20) =50m
     this is because his reaction time is 0.5 sec so he traveled 10m before stepping on the break paddle.

a= (V₀-V₁) / 2x
  = (0-20) / 2*50
  = -0.2m/s
the negative is because it is a deceleration speed hence it is 0.2m/s

A proton, moving in a uniform magnetic field, moves in a circle perpendicular to the field lines and takes time T for each circl
xxMikexx [17]

Answer:

option (B)

Explanation:

mass of proton, m = m

charge of proton, q = e

Time period, T = T

Initially the speed of proton is v.

The time period of the proton when it is moving in magnetic field perpendicular to the direction of magnetic field is given by

T=\frac{2\pi r}{v}

Where, r be the radius of circular path.

The relation between r and the speed v is given by

r=\frac{mv}{Bq}

Where, B be the strength of magnetic field. Substitute this value of r in the expression of time period

T=\frac{2\pi mv}{Bqv}=\frac{2\pi m}{Bq}

Here, we observe that the expression for the time period is independent to v and r so, as we change the velocity, the time period remains same.
