Answer:
Fc = 89.67N
Explanation:
Since the rope is unstretchable, the total length will always be 34m.
From the attached diagram, you can see that we can calculate the new separation distance from the tree and the stucked car H as follows:
L1+L2=34m
Replacing this value in the previous equation:
Solving for H:

We can now, calculate the angle between L1 and the 2m segment:

If we make a sum of forces in the midpoint of the rope we get:
where T is the tension on the rope and F is the exerted force of 87N.
Solving for T, we get the tension on the rope which is equal to the force exerted on the car:

The correct answer for the statement “All the scientific
theories used to explain the formation of the solar system are non-testable”. The
answers outdated, imaginative and unacceptable are wrong. These theories are
not proven and yet are not tested due to the complexity.
Answer: The time of contact will be 0.006 seconds.
Explanation:
An impulse of a force is the product of average force and the time interval when the force acts.
Mathematically,

Where,
J = impulse = 3.6 Ns
F = Force = 600N
= Time = ?s
Putting the values in above equation, we get:

t = 0.006 seconds
Hence, the time of contact will be 0.006 seconds.
In the process of finding an image with a lens, three basic lines are usually drawn, the lines are as follows:
LINE ONE: This line represents the ray that leaves the object and travels towards the center of the lens. This line is usually undeflected and it travels through a straight line.
LINE TWO: This line represents the ray which travels from the object parallel to the axis of the lens. The line is deflected in such a way that it passes through the focal point of the lens.
LINE THREE: This line represents the ray that travels from the object and which passes through the focal point on the near side prior to getting to the lens. This line is deflected in such a way that it travels parallel to the axis. <span />
