Answer: force from sun to mars = , force from mars to sun =
Explanation: The force of attraction or repulsion between 2 object ( in this case the sun and mars ) in space is given by newton's law of gravitation which is given mathematically below as
where
G = gravitational constant, = mass of mars, = mass of sun
the mars also exerts the same magnitude of force above on the sun but in the opposite direction, thus the force mars exerts on the sun is
Answer: Volume of a gas is inversely proportional to pressure of that gas in any container.
Explanation:
Hi, according to Boyle's Gas law, the volume of a gas is inversely proportional to the pressure of that gas, at a constant temperature.
The expression is:
P1.V1= P2.V2
V= 1/P
PV = k
Where:
P = pressure of a gas
V = volume of a gas
k = constant

Answer:
Velosity :
V = 3 m/s
Explanation:
Given:
m = 15 kg
F = 150 N
R = 90 cm = 0.90 m
________________
V - ?
Acceleration:
(1) a = F / m
(2) a = V² / R
Equate (2) and (1):
V² / R = F / m
Velocity:
V = √ (F·R / m)
V = √ (150·0.90 / 15) = √ 9 = 3 m/s
Answer:
45 kg is the mass of a table that weights 441 newton.
