We can solve the problem by using Ohm's law, which states that an Ohmic conductor the following relationship holds:
where
is the potential difference applied to the resistor
I is the current flowing through it
R is the resistance
In our problem, I=4.00 A and
, so the potential difference is
Answer:
A goal.
Explanation:
This is clearly seen to be a scenario of a sporting event. It is seen to have certain set down rules that it is been strictly played by. In different occasions, it is seen to favour an opposing or defending side. In the case here where the ball did not touch or foul anyone after its hit on the woodwork, and been shot into the net, it can be counted to be a goal. There are different rules which ranges from penalty to offsides, to throw-in etc which makes the game lively and controlled very well.

Explanation:
I am not entirely sure about them, but most should be correct.
A theory cannot become a law because it explains what is observes and does not describe it.
Answer:
7.481W
Explanation:
power= work done÷time
power= force × uniform velocity
a= ∆v/t
29.0ms=
=(0.72-0)÷29×10^-3
a=24.83m/s^2
Newton's second law
f=ma
=(0.84×24.83)
=20.86N
w=FD
v^2=u^2+2as
0.5184=0+49.66s
s=0.0104m
20.86×0.0104
=0.216944J
0.216944÷t
P=7.481W
