Answer:
the displacement would be 32 m
Explanation:
there is no formula for displacement, but you can use the velocity formula as you have the velocity and time so it looks like:
with x being the displacement
A small coin of mass m1 is undergoing a uniform circular motion at a velocity v. The radius of the circular path is r. A piece o

Given that,
Current = ∞
We know that,
Ohm's law :
Ohm's law is defined as,
The voltage of the circuit is directly proportional to the current of the circuit.
Or,
The voltage of the circuit is equal to the product of current and resistance.
In mathematically,
Where, V = voltage
I = current
R = resistance
According to ohm's law,
The current in the circuit is
If the current is very less then the resistance will be infinity.
If the is reach to infinity then the resistance will be very low.
Hence, The resistance becomes very low.
Explanation:
The given data is as follows.
Mass, m = 75 g
Velocity, v = 600 m/s
As no external force is acting on the system in the horizontal line of motion. So, the equation will be as follows.
where, = mass of the projectile
= mass of block
v = velocity after the impact
Now, putting the given values into the above formula as follows.
=
v = 0.898 m/s
Now, equation for energy is as follows.
E =
=
= 13500 J
Now, energy after the impact will be as follows.
E' =
= 20.19 J
Therefore, energy lost will be calculated as follows.
= E E'
= (13500 - 20) J
= 13480 J
And, n =
=
= 99.85
= 99.9%
Thus, we can conclude that percentage n of the original system energy E is 99.9%.
