Answer:
1.5 km/s²
Explanation:
Given that:
a car starts from rest; it means the initial velocity (u) = 0 km/hr = 0 m/s
after time (t) = 20 seconds
the final velocity = 108 km/hr = 30 m/s
The acceleration (a) of the car can be determined by using the formula:
a = 1.5 km/s²
Answer:
equal to the net electric field.
Explanation:
The electric field potential due to any charge at any point is defined as the force of the given charge on a unit positive test charge. The direction of the electric field potential is the direction of the force on the test charge due to the given charge.
- At any equidistant point in the space from the two charges equal in magnitude opposite in nature the net electric field potential will be equal to the vector sum of the electric field at that point which becomes zero only if the point lies on the line joining the charges.
Answer:
0.217 m/s
Explanation:
The protons in the beam passes undeflected when the electric force is equal to the magnetic force:
qE = qvB
where
q is the proton's charge
E is the magnitude of the electric field
v is the speed of the protons
B is the magnitude of the magnetic field
Re-arranging the equation,
And by substituting
E = 0.5 N/C
B = 2.3 T
We find
Your answer should be:
Acceleration
