The wave oscillates in a single plane. so the answer would be (c) i think
Answer:

Explanation:
We'll use the momentum equation:

where:
p = momentum
m = mass
v = velocity
Since we're doing the magnitude of momentum of the system, we'll add the mass of the cyclist and the mountain bike together:

Given that, we can now substitute our given values into the momentum equation:

Our final answer is:

This answer is the same for all elements, a single atom of any element is still that element.
Answer:
The impedance of this circuit is 200 ohm.
Explanation:
Given that,
rms voltage = 120 v
Frequency = 60.0 Hz
rms current = 0.600 A
We need to calculate the impedance
Using formula of impedance

Where,
= rms voltage
= rms current
Z= impedance
Put the value into the formula


Hence, The impedance of this circuit is 200 ohm.
Answer:
Static friction
Explanation:
When there is contact between two surfaces and there is no movement, there is static friction. So, if we have a book that rests on a wooden table, we have an example of Static friction, where this force avoids the movement of the book.
