Answer:
The velocity of the wave is, v = 180,000 m/s
Explanation:
Given data,
The frequency of the wave, f = 900 Hz
The wavelength of the wave, λ = 200 m
The formula for the speed of the wave when the frequency and wavelength are known,
v = λ x f
Substituting the given values in the above equation,
v = 200 m x 900 Hz
v = 180000 m/s
Hence, the velocity of the wave is, v = 180,000 m/s
Because of the gravity on earth, and the momentum they get from spinning around the planet.
Answer:
The man is on the verge of having a heart attack or a stroke.
Explanation:
If he has a family history of coronary (heart) disease, it means it could normally affect. Normally here means without anything aggravating it. It's already in his lineage so he could have it.
Now, he's past middle age - he's 45. He's past the growing stages of life. His organs are fully developed herefore.
Now also, he suffers from Type 2 diabetes. Although this is sometimes milder than Type 1 diabetes, it increases the risk of having a heart disease or a stroke!
Soda, especially sweetened one, is not to be taken too often because it can cause Diabetes Mellitus. For a diabetes patient, this should be a "no-go-area". Taking this constantly (everyday at work) will now put this 45-year-old man in harm's way.
He is no more at risk of having complications but already on the path to a heart disease or a stroke.
As the wave travels through different media, its speed and wavelength change, and its frequency remains constant.

I believe the correct answer
to this is: No, there is no force pushing you backward.
<span>In this case, since the jet is pushing forward hence the person is also
actually feeling the seat of the jet pushing forward. Due to Newton’s 3rd
law, the person exerts an equal force back onto the seat causing him to lean
backward. </span>
