On the other side of the gorge, at the highest point of his swing, the vine makes an angle of \theta=40^\circθ=40 ​∘ ​​ from the

vertical. At this point, Tarzan's speed is instantaneously zero (as he transitions from swinging up to swinging back again). What is the tension in the vine at the highest point of his swing?

Answer:

T = m*g*cos\theta

Explanation:

Since tarzan moves in a circular trajectory we can sum all forces on the centripetal-axis:

T - m*g*cos\theta = m*a_c

T - m*g*cos\theta = m*V^2/R   Since the speed is zero:

T - m*g*cos\theta = 0

T = m*g*cos\theta Having Tarzan's mass we could calculate the module of the tension in the vine.

every object that has mass attracts every other object with a gravitational force. it has been proven that the size of the gravi
erastova [34]

Answer;

- This statement about matter and its behavior is best classified as a Law.

-It is the Law of Universal Gravitation.

Explanation;

-The Law of Universal Gravitation states that every point mass attracts every other point mass in the universe by a force pointing in a straight line between the centers-of-mass of both points, and this force is proportional to the masses of the objects and inversely proportional to their separation.This attractive force always points inward, from one point to the other.

-The Law applies to all objects with masses, big or small. Two big objects can be considered as point-like masses, if the distance between them is very large compared to their sizes or if they are spherically symmetric.

Which of the following graphs correctly represents the relationship between the pressure and the volume of an ideal gas that is
vazorg [7]
Well, you haven't given us much of a choice of graphs to pick from, have you.

If a sample of an ideal gas is held at constant temperature, then
its pressure and volume are inversely proportional ... the harder
you squeeze it, the smaller the volume gets, and less squeeze
produces more volume.

Actually, the product of (pressure) x (volume) is always the
same number.

The graph of that relationship is all in the first quadrant.
It starts out very high right next to the y-axis, then drops down
toward the x-axis while curving to the right and becoming horizontal,
and ends up trying to get closer and closer to the x-axis but never
actually becoming zero.
