Transverse waves is the answer.
Hope I helped if you need anything else ask me
Answer:
The energy transferred is 2.93 MJ.
Explanation:
Given that,
Time = 1 h = 3600 s
Area
Width
Temperature
For concrete wall,
The thermal conductivity
k = 1.7 W/mK
Using Fourier's law
Where, A = area
= width
= change in temperature
k = thermal conductivity
Put the value into the formula
The energy transferred in 1 hour
Hence, The energy transferred is 2.93 MJ.
Answer:
Induced current,
Explanation:
Given that,
Area of cross section of the wire,
Time, t = 2.2 s
Initial magnetic field,
Final magnetic field,
Resistance of the coil, R = 8 ohms
The expression for the induced emf is given by :
= magnetic flux
So, the induced emf in the loop is 0.023 volts. The induced current can be calculated using Ohm's law as :
So, the magnitude of the induced current in the loop of wire is . Hence, this is the required solution.
The answer is d. I hope that helps.
Answer:
The maximum value of the driving force is 1044.01 N.
Explanation:
Given that,
Weight of the object, W = 50 N
Force constant of the spring, k = 210 N/m
The system is undamped and is subjected to a harmonic driving force of frequency 11.5 Hz.
Amplitude, A = 4 cm
We need to find the maximum value of the driving force. The force is given by the product of mass and maximum acceleration as :
.....(1)
A is amplitude
m is mass,
is angular frequency
Angular frequency is given by :
Equation (1) becomes :
So, the maximum value of the driving force is 1044.01 N.
