Answer:

It uses graivity and momentum because since we all know, gravity pulls things down, they have a chaint hat lifts the carts up, and then when it gets to a top, it releases it. When it goes down very high, it will go faster. Then it uses momentum when it goes up, then down again, or a loop to regain speed. IT doesn't need a engine or a motor to speed it up or slow it down because gravity and momentum is already doing the job a engine could. Like I said, when it is high in the sky and released, it goes down in incredible speed. And when it needs more speed to keep the ride going, it can add a loop or tight turns to increase it more.

Mashcka [7]

Answer:

Explanation:

When the central shaft rotates , the seat along with passenger also rotates . Their rotation requires a centripetal force of mw²R where m is mass of the passenger and w is the angular velocity and R is radius of the circle in which the passenger rotates.

This force is provided by a component of   T , the tension in the rope from which the passenger hangs . If θ be the angle the rope makes with horizontal ,

T cos θ will provide the centripetal force . So

Tcosθ = mw²R

Tsinθ component will balance the weight .

Tsinθ = mg

Dividing the two equation

Tanθ = \frac{g}{\omega^2R}

Hence for a given w , θ depends upon g or weight .

While performing an experiment, the student creating the data table is not sure if a measurement from the experiment is a vector
marin [14]

Before coming into conclusion first we have to understand both scalar and vector .

A scalar quantity is a physical quantity which has only magnitude for it's complete specification.

A vector quantity is that physical quantity which not only requires magnitude but also possesses direction for it's complete specification.

So the most important factor that differentiate vector from scalar is the direction.

As per the question the student is doing an experiment where he is recording the data obtained during the process.

In order to arrange them in data table, he should ask about the direction of the quantity under consideration.


Hence the correct option is the third option(C)i.e does the measurement include direction?
