Charge = 0.2 Ah is the correct answer...
Answer: 79.35 N
Explanation: according to the impulse momentum theorem,
Impulse = change in momentum
Where impulse = force × time and change in momentum = m ( v - u).
The object was initially at rest, hence it initial velocity is zero.
To get the final velocity, we use the formulae below
v² = u² + 2gh
Where h = height of the cliff = 17m
v² = 2 × 9.8 × 17
v² = 333.2
v = √333.2
v = 18.25 m/s
At t = 0.46s and v = 18.25 m/s, we can get the average force of impact
F×0.46 = 2 (18.25 - 0)
F × 0.46 = 2 (18.25)
F × 0.46 = 36.5
F = 36.5 /0.46 = 79.35 N

Answer
given,
mass of student = 60 Kg
mass of suitcase = 10 Kg
a) Work done by picking of Suitcase is equal to zero
b) acceleration = 0.1 m/s²
distance = 2 m
Using second law conservation
F = m a
F = 10 x 0.1 = 1 N
c) Work done
W = F x s
W = 1 x 2 = 2 J
d) When the are moving with constant speed acceleration is equal to zero
F = m a
F = 10 x 0 = 0 N
W = F x s = 0 x s = 0 J
e) work done = change in kinetic energy
K.E = 2 J
Answer:
The amount of energy carried by a wave is related to the amplitude of the wave
Explanation:
A high energy wave is characterized by a high amplitude; a low energy wave is characterized by a low amplitude. The energy imparted to a pulse will only affect the amplitude of that pulse.
Hope this helped!!!
