Answer:
537 N
Explanation:
The force due to gravity of a planet is:
F = GMm / r²
where G is the universal gravitational constant
M is the mass of the planet
m is the mass of the object
and r is the distance between the object and the center of the planet
On Earth, you weigh 716 N, so:
716 N = GMm / r²
On planet X:
F = G (3M) m / (2r)²
F = 3/4 GMm / r²
F = 3/4 (716 N)
F = 537 N
4 because its not yet moving. It has kinetic energy, it just hasn’t been used yet.
Answer:
The angle is 1.33°.
Explanation:
Given that,
Distance 
Wavelength = 650 nm
Number of fringe = 3
We need to calculate the angle
Using formula of angle for brightness


Where, d = distance
=wavelength
m = number of fringe
Put the value into the formula


Hence, The angle is 1.33°.
Net Force = (mass) x (acceleration) (Newton #2)
Net Force = (50 kg) x (6 m/s² down)
Net Force = (50 * 6) (kg-m/s² down)
<em>Net Force = 300 Newtons down</em>
The answer is 434J because kinetic energy is1/2Mv2
