Answer:
i think it might be scorpion it's not a brown recluse spider for sure because they are timid.
Answer:
Explanation:
B = Magnetic field = 1.1 T
L = Length of square = 10.4 cm
A = Area of square =
t = Time taken
V = Voltage = 120 V
N = Number of turns = 350
= Angular frequency
Voltage in the generator is given by
Voltage is maximum when
The minimum rotation rate of the coil so it will produce the required voltage is
Actually Welcome to the Concept of the Work And Energy.
So we here use the formula as,
W= Mgh
so after solving we get as,
W = 0.686 Joules
Answer:
Height of the image is 9.06 cm
Explanation:
As we know that the person is standing 250 cm from the lens
Now we know that the focal length of the lens is
f = 15 cm
now by lens formula we have
now we know by the formula of magnification
now we have
Those conditions are met when you have an elastic collision of equal masses.
So the answer would be a tennis ball.
Let us write momentum conservation law for this problem. The left-hand side is before the collision and right-hand side is after the collision:
What this equation means is that all momentum of the first ball is transferred to the second ball and velocities before and after the collision are the same.
There is no need to write energy conservation law. We can see that above equation holds true only if
.
