The correct answer among the choices given is option B. Equilibrium is achieved when the demand equals the supply. Equilibrium is a state when there are no changes observe in a phenomenon and for this case it is achieved when both values are the same.
Answer: B = 1.69 T
Explanation: Given that the
Electron velocity V = 7.4 × 10^5 m/s
Force F = - 2 × 10^-13 N
Charge q = -1.602 x 10-19 C.
We are given the charge, its velocity, and the magnetic field strength and direction. We can thus use the equation F = qvB sin θ .
Since the electron is moving perpendicular to a magnetic field,
sin θ = sin 90 = 1, therefore
- 2 × 10^-13 = - 1.602×10^-19 × 7.4×10^5B
B = -2×10^-13/1.2×10^-13
B = 1.68708T
B = 1.69 T
Answer:
The wave produced is a standing wave.
y' = [2ymax - kx] cos wt.
y max is maximum displacement, k is angular wave number, x is equal to the length L, w is angular frequency, t is time.
The time taken for the wave to travel to the ceiling and get reflected is given as:
t = 1/f = (2L)/nv. Where n =, 1,2,3, .... and v is wave speed, f is wave frequency.
Answer:

Explanation:
The three major difference between Pluto and the other Terrestrial planets are
1. Pluto's orbit is far from being circular. Its orbit has highest eccentricity,meaning that its distance from sun varies more than any other planet of the solar system.
2. The ratio of the size of the planet to size of moon is highest for the for Pluto. its moon Cheron is quite large which is surprising as Pluto gravitational force is not much.
3.Pluto's orbit is the most tilted orbit of the solar system.
Answer:
Can behave both as a particle and wave
Explanation:
Electromagnetic wave has the electric and magnetic wave propagating/oscillating together. Electromagnetic waves such as x Ray, gamma ray, radio waves are important in health care and modern information technology .
Electromagnetic waves have particles such as the electrons and protons. They are responsible for the existence of electromagnetic waves by the charged particles vibrating. Electromagnetic waves behave as waves majority of the time. Electromagnetic energy is released in distinct packs of energy called photons which are particles but acts like waves.
