Answer:
80 km
Explanation:
Since 240 divided by three is 80, the velocity the car is traveling at is 80 kilometers per hour.
Answer:
The acceleration of the proton is 9.353 x 10⁸ m/s²
Explanation:
Given;
speed of the proton, u = 6.5 m/s
magnetic field strength, B = 1.5 T
The force of the proton is given by;
F = ma = qvB(sin90°)
ma = qvB
where;
m is mass of the proton, = 1.67 x 10⁻²⁷ kg
charge of the proton, q = 1.602 x 10⁻¹⁹ C
The acceleration of the proton is given by;

Therefore, the acceleration of the proton is 9.353 x 10⁸ m/s²
C and D are units of length or distance.
A is a measured angle.
B is a unit of angular measurement.
The third choice is correct
