It would be 12W because: 6v is half of 12v so half of 24w would be 12w
Answer:
100years later
Explanation:
Because the lights will arrive at world after 100 years later.
Answer:
4
Explanation:
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
= Mass of Earth
= Mass of Moon
r = Distance between Earth and Moon
Old gravitational force
![F_o=\dfrac{Gm_1m_2}{r^2}](https://tex.z-dn.net/?f=F_o%3D%5Cdfrac%7BGm_1m_2%7D%7Br%5E2%7D)
New gravitational force
![F_n=\dfrac{Gm_1m_2}{(\dfrac{1}{2}r)^2}](https://tex.z-dn.net/?f=F_n%3D%5Cdfrac%7BGm_1m_2%7D%7B%28%5Cdfrac%7B1%7D%7B2%7Dr%29%5E2%7D)
Dividing the equations
![\dfrac{F_n}{F_o}=\dfrac{\dfrac{Gm_1m_2}{(\dfrac{1}{2}r)^2}}{\dfrac{Gm_1m_2}{r^2}}\\\Rightarrow \dfrac{F_n}{F_o}=\dfrac{\dfrac{Gm_1m_2}{\dfrac{1}{4}r^2}}{\dfrac{Gm_1m_2}{r^2}}\\\Rightarrow \dfrac{F_n}{F_o}=4](https://tex.z-dn.net/?f=%5Cdfrac%7BF_n%7D%7BF_o%7D%3D%5Cdfrac%7B%5Cdfrac%7BGm_1m_2%7D%7B%28%5Cdfrac%7B1%7D%7B2%7Dr%29%5E2%7D%7D%7B%5Cdfrac%7BGm_1m_2%7D%7Br%5E2%7D%7D%5C%5C%5CRightarrow%20%5Cdfrac%7BF_n%7D%7BF_o%7D%3D%5Cdfrac%7B%5Cdfrac%7BGm_1m_2%7D%7B%5Cdfrac%7B1%7D%7B4%7Dr%5E2%7D%7D%7B%5Cdfrac%7BGm_1m_2%7D%7Br%5E2%7D%7D%5C%5C%5CRightarrow%20%5Cdfrac%7BF_n%7D%7BF_o%7D%3D4)
The ratio is ![\dfrac{F_n}{F_o}=4](https://tex.z-dn.net/?f=%5Cdfrac%7BF_n%7D%7BF_o%7D%3D4)
The new force would be 4 times the old force
Answer:
Tension.
<em><u>tension</u></em> is the name of force that opposes or goes opposite of gravity
Hope this helps!
