To solve this problem we will apply the concepts related to magnetic flux and induced voltage. This last expression understood as the variation of the magnetic flux over time and, in turn, the magnetic flux expressed as the variation of the magnetic field in a certain area.
Magnetic flux through the circular coil is given as

The induced voltage is the change of the magnetic flux across the time, then

At the same time the magnetic flux through the square coil would be given as,

And the induced voltage EMF will be

Equating both expression we have



Therefore the emf induced in the square coil is 0.23355V
Answer:
Explanation:
Weight is actually a force. A force can change depending on its location. A mass remains constant no matter where it is.
A)
F = m * a
m = 250 kg
a = 9.81 m/s^2
F = 250 * 9.81 = 2452.5 N
B)
The acceleration due to gravity on the moon is roughly 1/6 what it is on earth. You can check its value in your notes.
a = 9.81 + (1/6) = 1.635
m = 250
F = 250 * 1.635
F = 408.75
C)
The mass is the same anywhere in the universe.
250 kg
The unstable nuclei undergo radioactive decay. The nucleus decay in form of emitting the radiations or changing into the different chemical element.
Thus, the nucleus decay takes place till the nuclei become stable.
Hence, given statement is false.
Answer:


Explanation:
Recall the formula for linear momentum (p):
which in our case equals 26.4 kg m/s
and notice that the kinetic energy can be written in terms of the linear momentum (p) as shown below:

Then, we can solve for the mass (m) given the information we have on the kinetic energy and momentum of the particle:

Now by knowing the particle's mass, we use the momentum formula to find its speed:

Option number three is correct energy can be transformed and moved and released but it can't be destroyed and doesn't disappear.
