Answer:
Velocity increases
Explanation:
Gravity is constant, except when discussing "apparent weight"
Mass is constant here
Air resistance would actually increase
Velocity DOES increase, because Earth is pulling the jumper downwards with an unbalanced force. The unbalanced force creates acceleration (-9.81 m/s^2), which means his velocity is increasing constantly.
There is a basic difference<span>, because </span>mass<span> is the actual amount of material contained in a body and is </span>measured<span>in kg, gm, etc. Whereas </span>weight<span> is the force exerted by the gravity on that object mg. Note that </span>mass<span> is independent of everything but </span>weight<span> is different on the earth</span>
Answer:
4.275v

Answer:
a)
b)
Explanation:
For this case we have the following frequency given:
We can convert this into Hz like this:
If we have a fundamental wave we need to satisfy the following condition:
If we solve for the wavelength we got:
We know that the velocity of the light is
And if we replace into the last formula we got:
Part b
For this case we can use the same formula but on this case the velocity of the sound at 20C is approximately 343 m/s, the frequency is given by:
We use the same wavelenght from the previous part
And if we replace the new values we got:
Answer:
365
Explanation:
A calendar is equal to a year and it is 365 days in a year.
