Answer:

Velocity of proton will be equal to 4500 m/sec

Explanation:

We have given that proton moves right angles through a magnetic field

So angle between magnetic field and velocity of proton is \Theta =90^{\circ}

Magnetic field B = 0.025 Tesla

Charge on proton e=1.6\times 10^{-16}C

Magnetic force on the proton is given F=1.8\times 10^{-14}N

Magnetic force on a moving charge particle is equal to F=qvBsin\Theta

So 1.8\times 10^{-14}=1.6\times 10^{-16}\times v\times 0.025\times sin90^{\circ}

v = 4500 m/sec

So velocity of proton will be equal to 4500 m/sec

In 0.60 seconds, a projectile goes from 0 to 610 m/s. What is the acceleration of the projectile?
IceJOKER [234]

Answer: a=1016.66 m/s^{2}

Explanation:

Acceleration a is expressed in the following formula:

a=\frac{V_{f}-V_{o}}{t}

Where:

V_{f}=610 m/s is the final velocity of the projectile

V_{o}=0 m/s  is the initial velocity of the projectile

t=0.6 s is the time

Solving:

a=\frac{610 m/s-0 m/s}{0.6 s}

a=1016.66 m/s^{2} This is the acceleration of the projectile
