The gravitational effect on
other bodies determines the weight (or the mass) of a planet. We
must somehow measure the strength of its "tug" on another object in
order to use gravity to find the mass of a planet. We can harness Newton's
equations to deduce what the mass of the planet must be through observing
the time it takes for the satellite to orbit its primary planet.
Given:
Mass of Venus = 4.87 x 1024 kg
= 4986.88
Mass of Jupiter = 1.898 x 1024 kg
= 1943.552
Mass of Jupiter compared to mass of
Venus
1943.552 / 4986.88
= 0.3897330595482546
= 0.3897330595482546 x 100%
= 38.97%
So, in this problem, <span>the mass of Jupiter is about 0.39 times the mass of Venus.</span>
Answer:
0.2358
Explanation:
We need here apply the law momentum conservation, for objects who collide.
The equation is given by,
Our values are giving by,
We replace in our equation and solve for V_f, then
Therefore their final velocity is -0.2358m/s (Negative symbol only indicate change in the direction)
Liters
Grams
Degrees Celsius
The other answer choices are from the imperial system
Answer:
a
b
Explanation:
From the question we are told that
The spring constant is
The mass of the block is
Considering question a
Generally the weight of the block is mathematically represented as
=>
=>
Generally the force exerted on the spring is mathematically represented as
At equilibrium
=>
=>
=>
Considering question b
Generally the energy stored in the spring is mathematically represented as
Now the potential energy of the block before it is drooped is mathematically represented as
Generally from the law of energy conservation we have that
=>
=>
=>
I don't understand this, sorry!
