Answer is B.
In a lever, the effort arm is 2 times as a long as the load arm. The resultant force will be twice the applied force.
Hope it helped you.

Answer:
Explanation:
Given
mass of satellite
orbital radius
mass of Earth
Minimum amount of Energy to move Satellite from its orbit to an infinite distance is sum of Potential Energy + Kinetic Energy of Satellite
Where
i.e. Energy is required to provide to move Satellite out of its orbit
To solve this problem it is necessary to apply the concepts related to the kinematic equations of linear motion. For this purpose, we will use the definition of the speed equivalent to the displacement made by a body in a fraction of time. From this definition we will relate the time and distance variables required in the problem
Here,
v = Velocity
d = Distance
t = Time
With our values we have,
The speed of light is the speed at which waves move, therefore using the same formula above, but to find the distance we would have
Here,
c = Speed velocity
We have then,
Therefore the distance between the Earth and the spaceship is
Answer:
The amount by which the second filter reduces the intensity of light emerging from the first filter is
z = 0.60
Explanation:
From the question we are told that
The angle between the axes is
The intensity of polarized light that emerges from the second filter is mathematically represented as
Where is the intensity of light emerging from the first filter
This means that the second filter reduced the intensity by z = 0.60
It takes 365 days to orbit the sun...hence why our years are so long
