Answer in units of m/s?.
Answer:
0.025 A
Explanation:
A = 50 cm^2 = 50 x 10^-4 m^2
B2 = 6 T, B1 = 2 T
db = 6 - 2 = 4 T
dt = 2 s
R = 0.4 ohm
Let i be the magnitude of induced current and e be the induced emf.
According to the Faraday's law of electromagnetic induction
e = dФ / dt
e = A dB / dt
e = 50 x 10^-4 x 4 / 2 = 0.01 V
i = e / R = 0.01 / 0.4 = 0.025 A
Answer:
I’m so sorry I tried solving it but I don’t understand it can you explain the question a little bit more ty
Explanation:
The ceiling of a concert hall and conference halls are made curved so that the sound that emanates from the source will reflect to any point of the curve of these halls. Thereby, increasing the sound wave travelled across the hall.
Answer:
Farsighted and Nearsighted
Explanation:
Answer : 5.25 Calories is equivalent to 21.966 Joules.
Explanation :
The capacity to do any work is called its energy. Its SI unit is joules. Another unit of energy is joules.
The relation between the calorie and the joule is :
To convert 5.25 calories to joules we have to use unitary method i.e.
So, 5.25 C = 21.966 Joules.
Hence, this is the required solution.
