A it sinks the submarine because of the water that is going into the submarine
The dimension of K is M/ T^2
according to the question T=2π square root ofm/k here 2 pi is constant so
T= root of m /k and root of k = root of m/ T now by squaring on both the sides we get the answer k= M/ T^2
complete question :
A spring is hanging down from the ceiling, and an object of mass m is attached to the free end. The object is pulled down, thereby stretching the spring, and then released. The object oscillates up and down, and the time T required for one complete up-and-down oscillation is given by the equation T=√2πm/k, where k is known as the spring constant. What must be the dimension of k for this equation to be dimensionally correct?

Answer:
a. The stored electric field energy can be greater than the stored magnetic field energy.
b. As the capacitor is discharging, the current is increasing.
d. The stored electric field energy can be less than the stored magnetic field energy.
e. The stored electric field energy can be equal to the stored magnetic field energy.
Explanation:
We know that total energy of capacitor and inductor system given as
L=Inductance ,I =current
C=Capacitance ,V=Voltage
The total energy of the system will be remain conserve.If energy in the inductor increases then the energy in the capacitor will decrease and vice -versa.
The values of stored energy in the capacitor and inductor can be equal ,greater or less than to each other.But the summation will be constant always.
Therefore the following option are correct
a ,b , d , e
Answer:
11,520N
Explanation
According to Newtons second law
Net force = mass * acceleration
Given
Mass = 2560kg
acceleration = 4.5m/s^2
Substitute the given values into the formula
F = 2560 * 4.5
F = 11,520N
Hence the net force on the elevator is 11,520N
Answer:
33.988u
Explanation:
Both atomic mass units and molar mass are the same. It follows the same procedure and no complex path.
The atomic mass unit is the mass of one mole of an atom usually given in g/mol or some time amu.
To solve for H₂S;
Atomic mass unit of H = 1.008u
Atomic mass of S = 31.972u
Molecular mass in atomic mass unit = 2(1.008)u + 31.972u = 33.988u
