You want to determine whether the mass of an object attached to a parachute affects the time it takes to fall to the ground. In

this investigation, would "the material the parachute is made out of" be a suitable control variable? no or yes​

Answer:

The Answer is below!!

Explanation:

The larger the area of the parachute, the more air needs to be pushed out of the way, and so the slower it descends. the independent variable is the shape of the parachutes' canopies. The dependent variable is the drop speeds of the parachutes. How long does it take for the parachutes to reach the ground? Measure this using a stopwatch.

Hope I Helped!!

3. A train has broken through the wall of a train station. During the collision, what can be said about the force exerted by the
hram777 [196]

Answer:

c. The force exerted by the train on the wall was the same in magnitude as the force exerted by the wall on the train.

Explanation:

Newton's Third Law states that if a body exerts a force on another body, this body exerts a force of equal magnitude but in the opposite direction on the body that produces it. So, one body cannot exert a force on another without experiencing a force in itself.

Consider two uniform solid spheres where one has twice the mass and twice the diameter of the other. The ratio of the larger mom
Firdavs [7]

Answer:

The ratio of moment of inertia of larger sphere to that of smaller sphere = 4

Explanation:

The moment of inertia of solid sphere is given by I = 2/5MR² where M = mass of sphere and R = radius of sphere.

Radius of smaller sphere = D/2

Radius of larger sphere = 2D/2 = D.

Moment of inertia of smaller sphere I₁ = 2/5M × D²/4 = MD²/10

Moment of inertia of larger sphere I₂ = 2/5M × D² = 2MD²/5

The ratio of moment of inertia of larger sphere to that of smaller sphere = I₂/I₁ = 2MD²/5 ÷ MD²/10 = 10 × 2/5 = 4

As the frequency of a wave increases the wavelength.
zaharov [31]

Answer:

decreases

Explanation:

Remeber:

There is always inverse relation between frequency and wavelength.

So if one of them increases, other decreases and vice-versa.

What are the dimensions of a frequency in physics
Burka [1]

Answer:

This is the information I can provide. I hope it helps

Explanation:

Frequency is measured in units of hertz (Hz) which is equal to one occurrence of a repeating event per second. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency.
