The answer would be velocity because its stating the speed and direction of the car.
Answer:
1.25 m/s
Explanation:
divide 120 by 120 to get one second and then divide 1t0 by 120 to get the number
When an object is free-falling, no other force is acting upon it but the gravitational force. Because of this, the equations of motion are simplified. We can determine first the initial velocity:
v = √2gy = √2(9.81)(4.9) = 9.805 m/s
Then, we use this to the equation below:
y = vt + 1/2*at²
y = (9.805)(0.5) + 1/2(9.81)(0.5)²
y = 6.13 m
Electric force occurs between positive and negative electric charge. It can be calculated with formula
where F is force, Q1 and Q2 are charges, A is area of object usually ball (
) because we describe charges as points in space like electrons and protons,
is a natural dielectric constant of empty space or vacuum (
) and
also known as relative dielectric variable.
There are two types of the force:
1. Attractive electric force
2. Repulsive electric force
Attractive electric force occurs between positively and negatively charged objects while repulsive occurs between equally charged objects for eg. (positive and positive will repulse).
Answer:
a)
m/s
b)
Angular frequency = 
Explanation:
As we know

q is the charge on the electron =
C
B is the magnetic field in Tesla =
T
r is the radius of the circle =
m
mass of the electrons =
Kg
a)
Substituting the given values in above equation, we get -
m/s
b)
Angular frequency =
