Answer:
This refers when a spiker quickly strides towards the net before they jump in the air for an attack.
Answer: A) True, you are correct
==================================================
Explanation:
Power in physics is defined as
power = (change in work)/(change in time)
which shows that power is basically the rate of work done. We can think of it like a speed of sorts.
------------
For example, if you apply 100 joules of work over 2 seconds, then,
power = (100 joules)/(2 seconds)
power = (100/2) joules per second
power = 50 watts
A watt is defined to be a joule per second, and it's often used to measure how much electricity is consumed, but it has broader uses in physics as well.
Answer:
No. ... UV light causes sunburn, whereas visible light does not.

Explanation:
Two straight wires
Have current in opposite direction
i1=i2=i=2Amps
Distance between two wires
r=5mm=0.005m
Length of one wire is ∞
Length of second wire is 0.3m
Force between the wire,
The force between two parallel currents I1 and I2, separated by a distance r, has a magnitude per unit length given by
F/l = μoi1i2/2πr
F/l=μoi²/2πr
μo=4π×10^-7 H/m
The force is attractive if the currents are in the same direction, repulsive if they are in opposite directions.
F/l = μoi1i2/2πr
F/0.3=4π×10^-7×2²/2π•0.005
F/0.3=1.6×10^-4
Cross multiply
F=1.6×10^-4×0.3
F=4.8×10^-5N
In the context of variables and measurement scales, the magnitude of the differences between the numbers on the scale is meaningful interval scale.
<h3>What is an interval scale?</h3>
It should be noted that an interval scale means a measurement where the difference between the variables is meaningful and equal.
In this case, in the context of variables and measurement scales, the magnitude of the differences between the numbers on the scale is meaningful interval scale.
