In a coal-fired steam station – much like a nuclear station – water is turned into steam, which in turn drives turbine generators to produce electricity.
Answer:
1. 3.75
2. 1.39 ft
Explanation:
The mechanical advantage is the ratio of the resistance force to the effort force.
MA = 75 lb / 20 lb
MA = 3.75
The sum of the torques about the fulcrum equals zero.
∑τ = Iα
(20 lb) (5.2 ft) − (75 lb) x = 0
x = 1.39 ft
Round as needed.
Sound requires a medium to travel. Sound cannot travel in vacuum in space while light can. Therefore, the receiver from earth receives only light sent from moon, not sound.
Explanation:
- Sound is created by vibrations that requires medium to travel. The medium can be solid, liquid, or gas. Whatever it is, a medium is required.
- In space, there is no solid, liquid, or gas. In other words, it is vacuum. Sound waves cannot travel through vacuum.
- Light waves, on the other hand, can travel through vacuum. Hence, if the transmitter on moon emits sound waves and light waves, receiver from earth picks only the light waves.

Can you give me a brainlest?? :(
Explanation:
Answer:
Explanation:
Given that:
f = 250 Hz
= 2%
= 600 Hz
= 0.5 to 1.5 increment by 0.05
For 250 Hz = 250 cycle/sec
M = 0.98 , 1.02
At 0.7183 value of damping ratio the error value was 2% at 0.98 value of M
At 0.6330 value of damping ratio the error value was 2% at 1.02 value of M.
Hence, the damping ratio of the transducer must be placed between 0.6330 to 0.7183
