Answer: D. The force and displacement are in the same direction.
Explanation:
The Work done by a Force refers to the release of potential energy from a body that is moved by the application of that force to overcome a resistance along a path with distance .
Work is a scalar magnitude, and its unit in the International System of Units is the Joule (like energy).
Now, when the applied force is constant and the direction of the force and the direction of the displacement are <u>parallel</u>, the equation to calculate it is:
(1)
When they are not parallel, both directions form an angle, let's call it . In that case the expression to calculate the Work is:
(2)
When the force and displacement are perpendicular to each other, and <u>no work is done</u>.

Answer:
Below
Explanation:
To find the wave speed of a wave you can use this formula :
wavespeed (v) = (frequency) x (wavelength λ)
Plug in our values :
v = (10Hz) x (2m)
v = 20 m/s
