Answer:
false
Explanation:
it's hydrogen. also hydrogen has one proton and stuff and helium two
Answer:
Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.

Answer:
367.57 nm
Explanation:
Given that the speed of the light in certain material is 0.6310 times the speed of light in vacuum.
Speed of light in vacuum = 3×10⁸ m/s
Speed of the light in that material = 0.6310×3×10⁸ m/s = 1.893×10⁸ m/s
The frequency of the light does not change but the wavelength of the light changes with change in the speed when light travels from one medium to another.
Thus, frequency = 5.15×10¹⁴ Hz
Using,
c = frequency × Wavelength
Wavelength = c / frequency = (1.893×10⁸ m/s) / (5.15×10¹⁴ Hz) = 367.57×10⁻⁹ m
Also,
1 nm = 10⁻⁹ m
<u>So, wavelength = 367.57 nm</u>
I believe it is because, due to the elephant's size, it makes it harder to change direction.
Answer:
W = 4.75 KW
Explanation:
First, we will calculate the heat to be removed:
Q = (No. of students)(Metabolic Power of Each Student)
Q = (190)(125 W)
Q = 23750 W = 23.75 KW
Now the formula of COP is:
<u>W = 4.75 KW</u>
