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
It's important because you have to know when to make it go faster or else you might not be able to go upside down or in a circle
There are 3 equations for power, P = VI = V^2/R = I^2/R
Given the values you have been given, we know we'll be using V^2/R.
Substituting the values in, we get:
P = 12^2/1.2 = 144/1.2 = 120W
Answer:
Please find the answer in the explanation.
Explanation:
Given that 16 g CH4 + 64 g 02 - 44 g CO2 + 36g H2O
To explain the law of conservation of mass and describe how the equation represents the law of conservation of mass, let me first start from law.
The law state that: mass can neither be created nor destroyed.
The mass of each element at the reaction side must be equal or the Same with the magnitude of mass at the product
The equation represents the law of conservation of mass because the mass of molecules at the right hand side is equal to or balance with the molecules at the left hand side. For example, the number of Oxygen, and othe elements are the at both side.
Answer:
r = 2.8524 x10⁷ m = 28524 km
Explanation:
First, we calculate the angular speed of the satellite:
Now, we use the formula for the gravitational force. Since gravitational force will be acting as the centrifugal force due to circular motion. Therefore,
where,
F = Gravitational Forc = 105 N
m = mass of satellite = 40.9 kg
v = linear speed of satellite = rω = r(3 x 10⁻⁴ rad/s)
r = radius of orbit = ?
Therefore,
<u>r = 2.8524 x10⁷ m = 28524 km</u>
