Answer:
485.62 N
Explanation:
To obtain the magnitude of unbalanced forces acting on the body;
Unbalanced Force = Horizontal Component of Applied Force - Frictional Force
Frictional Force = Horizontal Component of Applied Force - Unbalanced Force
f = frictional force = ?
F = Applied force = 593 N
m = mass of person = 49 kg
a = acceleration = 0.57 m/s²
θ = Angle with horizontal = 30°
Hence;
Horizontal Component of Applied Force = (593 N)(Cos 30°)
Unbalanced Force = (49 kg)(0.57 m/s²)
f = (593 N)(Cos 30°) - (49 kg)(0.57 m/s²)
f = 513.55 N - 27.93 N
f = 485.62 N
Answer:
Explanation:
Period of the pendulum will not change as the period is not a function of mass
T = 2π√(L/g)
Period of the spring oscillator will increase with larger mass because period is a function of mass.
T = 2π/ω = 2π/√(k/m) = 2π√(m/k)

The options are missing and they are;
A) the electric force increases because the balloon loses its charge.
B) the electric force increases because the distance increases.
C) the electric force decreases because the distance increases.
D) the electric force decreases because his hair loses its charge.
Answer:
Correct answer is option C - the electric force decreases because the distance increases.
Explanation:
The formula for electric force is;
F = k•q1•q2/r²
Where;
K is coulombs constant
q1 and q2 are particle charges
r is distance
So,looking at the formula given earlier, if we increase the distance, the denominator will increase and thus the Force will decrease.
So the correct option is option C
They would hit the ground at the same time. No matter the weight laws of physics.
