Answer:
it will show a continuous rise in value. The rise will be sinusoidal.
Explanation:
Answer:
The value of current generated would increase.
Explanation:
Electromagnetic induction is the process by which an electromotive force is induced due to a variation of magnetic field.
The induced current is directly proportional to rate at which the coil cuts the magnetic field. Using more powerful battery in the experiment would increase the rate at the the coil cuts the magnetic field, therefore increasing the rate of variation in the magnetic field. This effect would cause a greater deflection on the galvanometer's scale, showing an increase in the current generated.
This experiment proves that an alternating current can be produced from magnetic field.
Anytime that an unstable nucleus emits alpha or bets particles, the number of protons and neutrons changes. ... In the fission process, when the nucleus splits, both neutrons and energy are released
The specific gravity of the object’s material is 5.09.
<h3>To calculate the specific gravity of the object:</h3>
Weight difference = 9 - 7.2 = 1.8 N = Buoyant force of water
Buoyant Force in water(Fb) = density of water x g x volume of the body(Vb)
1.8 = 1000 x 9.81 x Vb
Vb = 1.8/9810 cubic meter
Now, in the air;
Weight of body = mg = 9 N
Mass of body,m = 9/9.81 Kg
So,
Density of body = m/ Vb
= 9/9.81 ÷ 1.8/9810
= 5094.44 kg per cubic meter
The specific gravity of body = density of body ÷ density of water
= 5094.44 ÷ 1000
= 5.09
Therefore, Specific gravity of body = 5.09
