Answer:
18.1347 m/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
g = Acceleration due to gravity = 9.81 m/s² = a
Total height the ball falls is 2.4619+14.3 = 16.7619 m
The speed at which the stone reaches the ground is 18.1347 m/s
For a current-carrying wire running perpendicular to a magnetic field, the magnetic force acting on the wire is given by:
F = ILB
F = magnetic force, I = current, L = wire length, B = magnetic field strength
Given values:
F = 0.60N, L = 1.0m, B = 0.20T
Plug in and solve for I:
0.60 = I(1.0)(0.20)
I = 3.0A
Answer:
Explanation:
According to Coulomb's law, the magnitude of each of the electric forces experiences by the two point charges is directly proportional to the product of the magnitude of both charges (
) and inversely proportional to the square of the distance(R) that separates them:
We have 
Answer:
A: Muscular strength refers to the amount of force in one effort, while muscular endurance refers to performing repeated movements.
Explanation:
Muscle Strength is the ability to exert a maximal amount of force for a short period of time.
Muscle Endurance is the ability to do something over and over for an extended period of time without getting tired.
Example of <u>Muscle Strength</u> in the gym: Doing 1 rep of a 220 pound squat.
Example of <u>Muscle Endurance</u> in the gym: Doing 50 100 pound squats in a row, moving to a rhythm.
