Answer:
The acceleration of the proton is 8.714 x 10⁸ m/s².
Explanation:
Given;
speed of the proton, v = 6.5 m/s
magnetic field strength, B = 1.4 T
The magnetic force on the proton is given as;
F = qvB
The force of the moving proton is given as;
F = ma
Thus, ma = qvB
where;
m is mass of proton = 1.673 x 10⁻²⁷ kg
q is charge of proton = 1.602 x 10⁻¹⁹ J
a is the acceleration of the proton
Therefore, the acceleration of the proton is 8.714 x 10⁸ m/s².
Velocity is defined by rate of change in the position
which we can also write as
while acceleration is defined as rate of change in velocity
so acceleration and velocity both are rate of change in position and rate of change in velocity with respect to time respectively
out of all above statement the correct answer must be
<u>Acceleration equals change in velocity divided by time. </u>
Answer:
<h2>18150 J</h2>Explanation:
The kinetic energy of the car can be found by using the formula
m is the Mass
v is the velocity
From the question we have
We have the final answer as
<h3>18150 J</h3>Hope this helps you
Answer:
The speed is 15 km/h or 4.16 m/s.
Explanation:
A boat travels the distance that separates Gran Canaria from Tenerife (90 km) in 6 hours. Which the speed of the boat in km / h? And in m / s?
Given that,
Distance, d = 90 km = 90000 m
Time, t = 6 hours = 21600 s
Speed = distance/time
or
So, the required speed is 15 km/h or 4.16 m/s.
