Answer:

Explanation:
The density of an object is given by

where
m is the mass of the object
V is its volume
In this problem,
m = 42 kg
V = 22 m^3
Substituting into the equation, we find the object's density:

Answer:
Rest and Motion are relative terms.
The answer is the suns gravity
When we form a right triangle connecting the edge of the knife to the center of the circle and the center of the knife to the center of the circle, the radius of the circle becomes the hypotenuse. Using the trigonometric function,
sin 60° = opposite / hypotenuse = 4 / hypotenuse
The value of the hypotenuse is 4.62 inches. Then, the diameter is twice this value which is 9.24 inches.
Answer:
<h3>The answer is 3.1 kg</h3>
Explanation:
The mass of an object can be found by using the formula

f is the force
a is the acceleration
From the question we have

We have the final answer as
<h3>3.1 kg</h3>
