Answer:

Explanation:
As we know that the mass is revolving with constant angular speed in the circle of radius R
So we will have

now the position vector at a given time is

now the linear velocity is given as



The answer is
h: sB and Sb
hd : sb
hr : SB
If I am reading this correct, the energy content would decrease for the liquid to solidify
Answer:
<h2>
The answer is </h2><h2>
a. 5g/mL</h2>
Explanation:
Given data
mass m= 45g
volume v= 9mL
we know that density=m/v
substituting our given data we have

What is Density?
The Density of a body can be defined as the ratio of mass to volume,
or
Density, mass of a unit volume of a material substance. The formula for density is
,
where d is density,
M is mass, and
V is volume.
Density is commonly expressed in units of grams per cubic centimetre.
