The best answer is D.
The engine sucks in air at the front. A compressor squeezes the air. The compressed air is sprayed with fuel and an electric spark lights the mixture. The burning gases expand and blast through the nozzle at the back of the engine. As the hot air is going through the nozzle, it passes through another set of blades called the turbine. The turbine is attached to the same shaft as the compressor. As the turbine spins, it also spins the compressor.
A is the best answer. This is what makes the magnetic field of the magnet.
Answer:
24.64m
Explanation:
The formula for calculating the wavelength is expressed as;
wavelength = Speed/frequency
Given
Speed = 6.9m/s
Frequency = 1/Period
Frequency = 1/3.6
Frequency = 0.28Hz
Get the wavelength
wavelength = 6.9/0.28
wavelength = 24.64m
Hence the wavelength of the waves traveling along the string is 24.64m
Incomplete question.The complete question is here
A strong man is compressing a lightweight spring between two weights. One weight has a mass of 2.3 kgkg , the other a mass of 5.3 kgkg . He is holding the weights stationary, but then he loses his grip and the weights fly off in opposite directions. The lighter of the two is shot out at a speed of 6.0 m/sm/s .What is the speed of the heavier weight?
Answer:
Explanation:
Given data
First weight mass m₁=2.3 kg
Second weight mass m₂=5.3 kg
Lighter weight speed v₁i= -6.0 m/s
To find
Heavier weight velocity v₂f
Solution
From law of conservation of momentum
