Answer:
Explanation:
R² = F₁² + F₂² + 2F₁F₂ Cosθ , R is resultant force , θ is angle between them
780² = 390² + 550² + 2 x 390 x 550 Cosθ
608400 = 152100 + 302500 + 429000 Cosθ
Cosθ = .3585
θ = 69 degree.
As we know that acceleration due to gravity is given by

here we know that
g = 3.60 m/s^2
M = ?

now we have


so above is the mass of Mars
Answer:
Last option in the list of possible answers, with U235 and n (neutron) in the left (originators) of the reaction diagram.
Explanation:
Uranium 235 (which is a fissile isotope of uranium) plus slow neutrons is what produce the chain reaction that feeds nuclear reactors.
Here's the <em><u>solution</u></em>,
Let the <em><u>shares</u></em> be 2x, 3x and 5x according to their shared <em><u>investment</u></em> ratio,
now, we know :
=》2x + 3x + 5x = 30000
=》10x = 30000
=》x = 3000
So, value of x = 3000
hence, the <em><u>share</u></em> of each <em><u>shareholder</u></em> is :
- kamal = 2x = 6000
- kamala = 3x = 9000
- Krishna = 5x = 15000
i hope it helped.....
