Answer:
C
Explanation:
Before making a hypothesis, background information is usually used. When you want to write a hypothesis, research is done first so that you can make the most educated guess possible.
Fc=mv^2/r so we get
2000kg*(25m/s)^2/(80m)= 15625N of force
hope this helps! Thank You!!
Answer:
The answer to the question is 7200
Answer:
160J
Explanation:
Given parameters:
Frequency = 16Hz
Wavelength = 10m
Unknown:
Waves speed = ?
Solution:
Waves speed is the product of frequency and wavelength;
Waves speed = fλ
f is the frequency
λ is the wavelength
Now insert the parameters and solve;
Waves speed = 16 x 10 = 160J
Answer:
Yes
Explanation:
Any transparent surface in practical is neither a perfect absorber of electromagnetic waves neither a perfect reflector. Generally all the transparent surfaces reflect some amount of irradiation and the other parts are absorbed and transmitted.
<u>That is given by as relation:</u>
where:
absorptivity which is defined as the ratio of the absorbed radiation to the total irradiation
reflectivity is defined as the ratio of reflected radiation to the total irradiation
transmittivity is defined as the ratio of total transmitted radiation to the total irradiation
