Answer:
k = 773.64 N/m
Explanation:
Given:
mass of the pellet, m = 3.56 x 10² kg
Compression in spring, x = 6.61 × 10⁻² m
Height of rise of the pellet, h = 4.83 m
Now, let k be the spring constant
From the concept of conservation of energy, we get
gravitation potential energy acquired by the pellet will be from the energy provided by the spring
thus,
where, g is the acceleration due to the gravity
on substituting the values, we get
or
1.685 = .002178 × k
k = 773.64 N/m
Answer:
Explanation:
Given
Diameter of Plates is D
distance between Plates is d
Energy Stored in the Plates is U
Suppose fixed Potential is V
Energy is given by
where C=capacitance
where A=area of Plates
Thus 
Keeping all other factors as same
For triple the Energy
divide 1 and 2 we get
Thus the diameter should be change to 
times of original value
Answer:
Current can be induced in a lot of ways. I'll try and list as much of these methods as I can here.
1. Moving a bar magnet relative to a wire coil
2. Moving a wire coil relative to a magnet.
3. Move a wire coil that has electricity flowing though it relative to a wire coil without electricity flowing through it.
4. Moving a current carrying circuit relative to a non-current carrying circuit
5. Rapidly opening and closing the switch of a current carrying circuit beside a non current carrying circuit.
6. Moving a bar magnet through the middle of a wire coil.
7. Moving a wire coil through a magnet
8. Moving a circuit relative to a magnetic field.
The main idea is to cause a change in the magnetic field, or to change the available area of the wire loop, or to change the angle between the field and the loop.
Explanation:
a plate with oceanic crust sinks beneath a plate with
continental crust is the answer
Yes. Since the wavelength of the red line in the Hydrogen spectrum is 656.5 nanometer. This confirms the possibility of seeing the spectral line with the same wavelength in the absorption spectrum of hydrogen atoms. The Hydrogen spectrum has the lower limit of 656.5 nm which still includes 656.5 nm in the range.
