The repeating pattern of a mineral's particles form a solid called a crystal.

The term used  for the ability of a mineral to break into flat surfaces is Cleavage.

Fracture describes how a mineral looks when it breaks apart in an irregular way.

<h3>What is a crystal?</h3>

A crystal  as well as the crystalline solid which can be described as a solid material  that have some   constituents in an order.

These constituents could be  atoms, molecules, or ions which are been  arranged in a highly ordered microscopic structure.

It should be noted that The repeating pattern of a mineral's particles form a solid called a crystal and The term used  for the ability of a mineral to break into flat surfaces is Cleavage and Fracture describes how a mineral looks when it breaks apart in an irregular way.

A bowling ball (mass = 7.2 kg, radius = 0.11 m) and a billiard ball (mass = 0.38 kg, radius = 0.028 m) may each be treated as un
Semenov [28]

Answer:

Explanation:

Given that

Mass of bowling ball M1=7.2kg

The radius of bowling ball r1=0.11m

Mass of billiard ball M2=0.38kg

The radius of the Billiard ball r2=0.028m

Gravitational constant

G=6.67×10^-11Nm²/kg²

The magnitude of their distance apart is given as

r=r1+r2

r=0.028+0.11

r=0.138m

Then, gravitational force is given as

F=GM1M2/r²

F=6.67×10^-11×7.2×0.38/0.138²

F=9.58×10^-9N

The force of attraction between the two balls is

F=9.58×10^-9N

nordsb [41]

Answer:

<h2>1320 J</h2>

Explanation:

The work done by an object can be found by using the formula

workdone = force × distance

From the question we have

workdone = 600 × 2.2

We have the final answer as

<h3>1320 J</h3>

In the Biomedical and Physical Sciences building at MSU there are 135 steps from the ground floor to the sixth floor. Each step
satela [25.4K]

Answer:

W = 16.5 Kj

P = 49.9 Watt

E = 16471

Explanation:

m = 73.5kg

t = 5min 30sec = (5×60) + 30 = 330sec

each step = 16.6cm = 0.166m

h = 135×0.166 = 22.41 m

g = 10 m/s²

(i) W = F × s = W × h = mgh

W = 73.5×10×22.41 = 16471.35

W = 16.5 Kj

(ii) Power = workdone/time

P = 16471.35/330

P = 49.9 Watt

(iii) The energy burnt in this process = 16471
