The formula that relates the 3 variables, namely: mass,
volume, and density is: Density = mass / volume.
Let us identify each variable:
Density - more accurately called the volumetric mass density of a
substance is its mass per unit volume. It is a key concept that examines how
materials communicate in a lot of things, i.e weather, material sciences,
engineering, and other fields of science.
Mass – defined as a property of
a physical body in Physics, and when a net force is applied,
it results to the measure of a specific
object’s resistance to acceleration.
Volume - <span>contained or
occupied by the space of a substance or shape (either by a solid, liquid, gas
or plasma state)</span>
Answer:
An unknown number of identical light bulbs are connected to a 15 V battery in parallel. The current through the battery is 2 A. If the light bulbs are connected to the battery in series, the current through the battery is 5 mA. How many bulbs are there?
3 bulbs are there from the analogy given above
Explanation:
<span>Arsenic has a more nonmetallic behavior than antimony because arsenic's atoms have fewer electron shells.</span>
Answer:
v = 1.28 m/s
Explanation:
Given that,
Maximum compression of the spring, 
Spring constant, k = 800 N/m
Mass of the block, m = 0.2 kg
To find,
The velocity of the block when it first reaches a height of 0.1 m above the ground on the ramp.
Solution,
When the block is bounced back up the ramp, the total energy of the system remains conserved. Let v is the velocity of the block such that,
Initial energy = Final energy
Substituting all the values in above equation,
v = 1.28 m/s
Therefore the velocity of block when it first reaches a height of 0.1 m above the ground on the ramp is 1.28 m/s.
recoils and must be tethered or he's gone.
