Answer:
Explanation:
Mass of the sum =
70% of this mass is
Mass of hydrogen in the sun is
Mass of a hydrogen atom =
Dividing the mass hydrogen in the sun by the mass of one hydrogen atom will give us the number of hydrogen atoms
The number hydrogen atoms in the Sun is
Answer: 51
Explanation:
Given
Output is 23 V
The square armature side is
Magnetic field
Rate of revolution
Angular speed
Peak voltage is given by
So, there are approximate 51 loops
Answer:
a)
b)
c)
Explanation:
a) The speed of a wave is given by the following equation:
Where:
λ is the wavelength
f is the frequency
b) The harmonic wave has the following equation:
A is the amplitude (2 m)
k is the wavenumber (2π/λ)
ω is the angular frequency (2πf)
c) Here we need to find the heigth at x=3 m and t =10 s, so we need to find y(3,10).
I hope it helps you!
D. because Isotopes will have the same atomic number because they are the same element but have a different atomic mass because they contain a different number of neutrons.
