After the remains of living organisms (plants and animals) were buried under the layers of the earth's crust, they were exposed to very high temperatures and pressures, which led to the concentration of carbon in it and thus turning it into fossil fuels used to produce fossil energy.
The composition of fossil fuels depends on the carbon cycle in nature, and is extracted from fossil materials such as coal, black petroleum coal, natural gas, and petroleum.
I hope it helped you^_^
Answer: f = 6.5Hz
Explanation:
Given that the
Speed V = 65 m/s
Wavelength (λ) = 10m
Wave speed is the product of frequency and wavelength. That is,
V = fλ
Substitute V and (λ) into the formula to get frequency f
65 = 10f
Make f the subject of formula
f = 65/10
f = 6.5 Hz
Therefore, the frequency of this wave is 6.5 Hz?
Answer:
75km
Explanation:
First we need to understand for how long the battery can work. We can do that by dividing the total distance traveled by the speed of the race car. Since we do have both measurements required we can find the time. And so we get......
Now in order to find distance traveled by an object we need to multiply its speed by the time it traveled. Now since we have both of this measurements we can fin the traveling distance. We do ......
x =
And just like this we get the answer 75km
Answer:5m/s² well I am not pretty sure but hope it's help
Explanation:
u=0m
final velocity ,v=50m/s
t=10s
(v-u)/t=(50-0)/10=50/10=5m/s²
