The required equation for the sine function can be written as; V = 120sin120πt
<h3>What is a sine function?</h3>
A sine function is a regular repeating function. We know that the voltage is represented using a sine function of the general form V= V-o sin2πft
Hence;
f = 60 cycles per second
V-o = 120 volts
So from the values that we have stated above;
V = 120sin120πt

Answer: The work done is W = 3528J.
Explanation: Work (W) is an amount of energy used to do determined movement. To calculate it, we use the formula, as the movement is horizontal:
W = F.d, where
F is force on the object
d is distance it went through.
The force acting on the crate is due to friction.
= μ .
μ is the kinetic friction
is the normal force
There is no up and down movement, so , with g = 9.8m/s²
= μ . m . g
= 0.9 . 80 . 9.8
= 705.6 N
Substituing into the work formula, we have:
W = . d
W = 705.6 . 5
W = 3528 J
The work done to move the crate across a distance of 5m is 3528 J.
Answer: The particle model, because only high-energy frequencies of lights can remove electrons.
Explanation: just did the test and got it right :)
The main equivalency we can find that exists between the solid volume and liquid volume is that they both contain a definite volume. In addition, they are collectively called condensed phases due to the particles having virtual contact with each other.
