Explanation:
<u>Density
</u>
The density of a substance is the mass per unit volume. The density varies with temperature and pressure.
The formula to calculate the density of a substance of mass (m) and volume (V) is:
We have a cube-shaped piece of copper of 4 cm of side length. The volume of the piece is:
Surprisingly, no other magnitude is required, thus the answer is:
Telepathy duhh like when SpongeBob stared at Patrick he know they where thinking the same thing or maybe that was because they are both idiots i dont know <span />
Answer:
<h3>30m</h3>
Explanation:
Velocity is the change of rate of displacement with respect to time.
velocity = displacement/time
Given
initial velocity = 15 m/s.
time taken =2 secs
Required
Displacement of the object
From the formula;
Displacement = Velocity * time
Displacement = 15 * 2
Displacement = 30m
<em>Hence the displacement of the object is 30m</em>
