I think im not really sure tho
Answer:
The x-component of is 56.148 newtons.
Explanation:
From 1st and 2nd Newton's Law we know that a system is at rest when net acceleration is zero. Then, the vectorial sum of the three forces must be equal to zero. That is:
(1)
Where:
, , - External forces exerted on the ring, measured in newtons.
- Vector zero, measured in newtons.
If we know that , , and , then we construct the following system of linear equations:
(2)
(3)
The solution of this system is:
,
The x-component of is 56.148 newtons.
Answer:
Option (2) : Sixteen times the first cube
Explanation:
If an object has more kinetic energy then its going to take more energy to stop it. a larger car has obviously more mass, meaning more kinetic energy, and a smaller car obviously wouldnt have as much energy, so it would take less to stop it. therefore, the larger an object is, the harder it is to stop. hope i helped :)
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>
