Less than. A machine should have equal or more output than input to have a high efficiency. :)
Answer:
The potential at a point is 400 V.
Explanation:
Given that,
The electric potential at a point that is halfway between two identical charged particles is 300 V
Potential V= 300 V
Let the distance between the charge is 2r.
The potential at mid point
Using formula of potential
At mid point,
...(I)
If the potential at a point that is 25% of the way from one particle to the other
We need to calculate the distance between the charge
We need to calculate the new potential
Using formula of potential again
Put the value of
Hence, The potential at a point is 400 V.
Answer:
3.50 m/s^2
Explanation:
the race is of 100 m.
time after which Marge crosses the finish line after t= 10.8 sec
time take by her to attain maximum speed t_o= 2.20 sec
a=
we know that
s= ut +1/2at^2
100= v
put a= here t_o= 2.20 sec
v= 7.72 m/s
now Marge acceleration a= = 3.50 m/s^2
The correct answer is false cause how can u fit your finger in a wall something it's to small
