The amplitude is equivalent to the coefficient of the sine function, so:
Amplitude = 1
The time period of a Sin(x) = 2π
The time period of Sin(4x) = 2π/4 = π/2
The period is π/2
Answer:
2.71 m
Explanation:
Force is the product of mass and acceleration
F=m*a
Work done is the product of force and distance
Work done=F*d
In this case;
F= 35 N
Work done = 95 J
95 =35 * d
95 /35 = d
2.71 m= d

Answer:
<h2>The answer is option C</h2>
Explanation:
The work done by an object given it's distance and force can be found by using the formula
<h3>work done = force × distance</h3>
From the question
force = 20 N
distance = 10 m
The work done is
work done = 20 × 10
We have the final answer as
<h3>200 J</h3>
