Answer: physical or mechanical weathering

Explanation:

Mechanical weathering which is also referred to as the physical weathering occurs when a rock is broken down into smaller pieces. In this case, there will be a physical change of the rock but its composition will not change.

Some examples include ice freezing and expansion of the cracks in the rock, Smstrong winds that carrycpieces of sand which then sandblast surfaces, moving water which causes abrasion etc.

What is the acceleration of a Porsche that can go from 15 mi/hr to 75 mi/hr in 4 seconds?
Elodia [21]

Hi there!

Acceleration = change in velocity / change in time = Δv/Δt

Thus:

a = (75 - 15)/4 = 60/4 = 15 mi/hr²

A trolley going down an inclined plane has an acceleration of 2cm/s^2 What will be its velocity
Snowcat [4.5K]

Answer:

V_{f} = 6 cm/s

Explanation:

<u><em>Given:</em></u>

Acceleration = a = 2 cm/s²

Time = t = 3s

Initial Velocity = V_{i} = 0 cm/s

<u><em>Required:</em></u>

Velocity = V_{f} = ?

<u><em>Formula:</em></u>

a = \frac{V_{f}-V_{i}}{t}

<u><em>Solution:</em></u>

2 = \frac{V_{f}-0}{3}

=> V_{f} = 2*3

=> V_{f} = 6 cm/s

Name two units for measuring the diameter of nucleus atom.
Evgesh-ka [11]

The two units for measuring the diameter of nucleus atom are femtometre and metre.

How do you measure the size of the nucleus ?

Nucleus size is expressed in fermi, often known as femtometers. between a lighter and a heavier nucleus. Despite its modest size, the nucleus contains the majority of an atom's mass. The weight or mass of the atom's nucleus and neutrons are determined by neutrons.

femtometre (fm), which equals 10^{-15} metre.

A nucleus' diameter largely depends as to how many particles it contains, from about 4 fm for a light nucleus like carbon to 15 fm for a heavy nucleus as lead.
