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
Explanation:
50 meters north in 10 seconds.
speed = distance ÷ time = 50 meters ÷ 10 seconds = 5m/s
Answer:
35.7 kg
Explanation:
We are given that
Left scale reads =200N
Right scale reads=150 N
We have to find the mass in kg.
We know that
Weight of child= Sum of two scales=200+150=350 N
Acceleration due to gravity=
We know that
Weight= mg
Using the formula
Hence, the mass of child=35.7 kg
Hi! I believe the correct answer is A. Do you have any other questions I can help you with? I would be glad too.

Dispersion
Explanation:
The best word that describes the phenomenon that gives rise to rainbow is dispersion of light.
Dispersion is the process by which white light is separated into different colors or radiation according to their different wavelength.
- In the atmosphere, rainbow is an arc of different colors that forms in the sky.
- Rainbow forms when light is dispersed by water in the atmosphere.
- When rainbow forms light is separated into its different colors and it can be seen in the sky.
