<u>Answer</u>
5.9 × 10¹⁴ Hz
<u>Explanation</u>
The wave equation states that;
V = λf
Where V ⇒ velocity of light
λ ⇒ wavelength
f ⇒ frequency
V = λf
3.0×10⁸ = 510×10⁻⁹ × f
Dividing both sides by 510×10⁻⁹,
f = (3.0×10⁸) / (510×10⁻⁹)
= 5.8824 × 10¹⁴ Hz
Answer to the nearest tenth, 5.9 × 10¹⁴ Hz.
Answer:
Moon and Earth both exert equal force on each other
Explanation:
As we know by the universal law of gravitation the force of gravitation is given by the formula
This is the mutual gravitational force on Earth and Moon by which they attract each other.
So here the force of attraction due to Earth on Moon as well as the Force due to Moon on Earth both will be same in magnitude and opposite in direction.
So here both forces is given as
Moon and Earth both exert equal force on each other
