Answer:

Option D.

Explanation:

Data:

Height (h) = 9 m
Gravity (g) = 9.8 m/s²
Velocity Final (Vf) = ?

Use formula:

Vf² = 2 * g * h

Replace:

Vf² = 2 * 9.8 m/s² * 9 m

Multiply gravity with height:

Vf² = 2 * 88.2

Multiply:

Vf² = 176.4

Solve the square root:

Vf = 13.3

How fast is the ball going?

The speed is going at a speed of 13.3 meters per second.

2 ways in which the effects of friction can be minimised in the experiment

Vlad [161]

Answer:

Friction can be minimized by using lubricants like oil and grease and by using ball bearing between machine parts. A substance that is introduced between two surfaces in contact, to reduce friction, is called a lubricant. Fluid friction can be minimized by giving suitable shapes to the objects moving in the fluids.

Explain with one example that different types of organisums live in one habitation

inn [45]

Answer:

When you look at a simple koi pond you can find Koi (the secondary consumer) that feeds off of the zooplankton (first consumer), they eat the phytoplankton (producers). All in a simple food chain

Explanation:

Basically, Koi eat the little animal plankton (zooplankton) that then eats the plant plankton (phytoplankton) that can only end when a part of that habitat is removed. If you got rid of the plant plankton then the whole chain would collapse and most likely die.
