Explanation:
I think the total resistance of the resistors is 1 ohm . it is also known as equivalent resistance.
hope it helps.
Answer:
4 m/s or 4 meters per second.
Explanation:
In order to calculate the speed of wave, you multiply the wavelength in meters and the frequency of the Wave in Hertz. 2 times 2 equals 4. The wave speed is always in m/s considering that the wavelength is also in meters.

Answer:
The person with locked legs will experience greater impact force.
Explanation:
Let the two persons be of nearly equal mass (say m)
The final velocity of an object (person) dropped from a height H (here 2 meters) is given by,
(
= acceleration due to gravity)
which can be derived from Newton's equation of motion,
Now, the time taken (say 
) for the momentum ( 
) to change to zero will be more in the case of the person who bends his legs on impact than who keeps his legs locked.
We know that,
Naturally, the person who bends his legs will experience lesser force since is larger.
A believe that’s called a reference point.
