Answer:
b. 1600 watts
Explanation:
Modulation is the process of impressing a low frequency signal unto a high frequency signal so a to transmit over long distance.
If the modulation index (m) for an AM wave is less than 1, modulation would occur with no distortion, if m = 1, modulation occurs but if m > 1, it leads to over modulation and loss in AM envelope.
The total output power of an AM is the sum of the carrier power, upper side band power and lower side band power.
Total output power of an AM 
Pc is the carrier power. Given that modulation (m) = 50% = 0.5:
Torque is equal to force times distance. first calculate the weight of the 8-0 kg weight, using the formula:
F = mg
where g is the accelration due to gravity ( 9.81 m/s^2)
F = 8 kg ( 9.81 m / s^2 )
F = 78.48 N
and torque = Fl
where l is the distance
t = (78.48 N ) ( 0.55 m )
t = 43.16 Nm is the torque
Answer:
A
Explanation:
Basically all the other answer are opposites like Exercise is an effective way to relieve stress and lots of Stress does have Negative effects on people
Answer:
240000 Joules
Explanation:
Applying,
The work that must be done by the frictional force of the brake to stop the car must be equal to the kinetic energy of the car.
W = mv²/2.................. Equation 1
Where W = work done by the frictional force of the brake, m = mass of the car, v = velocity of the car.
From the question,
Given: m = 1200 kg, v = 20 m/s
Substitute these values into equation 1
W = (1200×20²)/2
W = 240000 Joules
highest energy level to the ground state.
Explanation:
The transition from the highest energy level to the ground state.
An electron has a discrete amount of energy accrued to it in any energy level it belongs to.
Electrons can transition between one energy level or the other.
- When electrons change state, they either release or absorb energy.
- When an atom absorbs energy, they move from their ground to final state which is consistent with the energy of the final state.
- When electrons release energy, they move from excited state to their ground state.
- Electrons will release the greatest amount of energy when they move from the highest energy level to the ground state.
