If 2.0 j of work Is done raising a 180 g Apple how far was it lifted

andrew11 [14]

The apple is lifted by 1.1 m

<u>Explanation</u>:

Given that, mgh = 2 J and mass of apple = 180g
Step 1: convert grams to kg as work is given in SI units.

180 g = 0.18 kg

Step 2: substitute in the formula for work done.

0.18 * 10 * h = 2

Step 3: calculate the value of h from this formula.

h = 2/1.8

h = 1.11 m

What is the difference between acceleration and linear acceleration?

Akimi4 [234]

Explanation:

Linear acceleration is a type of acceleration of a body along a straight path or line.

Acceleration is defined as the rate of change of velocity with time.

Acceleration = $\frac{Change in velocity}{time}$

There are different types of acceleration .

linear acceleration is used to describe the rate of change of velocity of a body along a straight path with time.
centripetal acceleration is the rate of change of velocity of a body traveling along a circular path with time. It is directed towards the center.
Angular acceleration is the rate of change of angular velocity.

A 4kg block slides freely across a rough surface such that the block slows down with an acceleration of −1.25 m/s2 . What is the

Sophie [7]

Answer:

The coefficient of kinetic friction between the block and the surface is 0.127.

Explanation:

Given that,

The mass of a block, m = 4 kg

The acceleration of the block, a = -1.25 m/s²

We need to find the coefficient of kinetic friction between the block and the surface. The force of friction is given by :

$F=\mu mg\\\\ma=\mu mg\\\\\mu=\dfrac{a}{g}\\\\\mu=\dfrac{1.25}{9.8}\\\\\mu=0.127$

So, the coefficient of kinetic friction between the block and the surface is 0.127.

Which of the following is an indicator of good water quality?

Agata [3.3K]

The answer would be: c. High levels of dissolved oxygen

Oxygen is vital for most (aerobic) organism. Fish using oxygen that dissolved in the water so high level of dissolved oxygen will make the fish grow easier. Water with pH of 5 would be an acid water. Acid is corrosive and it can kill some organism that sensitive. High levels of fecal coliform mean the water contaminated with fecal material and must have a high level of bacteria.
