Density of cylinder is 4.82 g/cm³.
<h3>What is density of a substance?</h3>
Density is the ratio of the mass and the volume of a substance
The density of the cylinder is:
mass of cylinder = 50.12 g
volume of cylinder = πr²h
r = 1.62/2 = 0.81 cm
h = 5.04 cm
volume of cylinder = 22/7 * 0.81² * 5.04
volume of cylinder = 10.39 cm³
Density of cylinder = 50.12 g/10.39 mL
Density of cylinder = 4.82 g/cm³
In conclusion, density of a substance is the ratio of mass and volume of the substance.

Answer:
0.12
Explanation:
The acceleration due to gravity of a planet with mass M and radius R is given as:
g = (G*M) / R²
Where G is gravitational constant.
The mass of the planet M = 3 times the mass of earth = 3 * 5.972 * 10^24 kg
The radius of the planet R = 5 times the radius of earth = 5 * 6.371 * 10^6 m
Therefore:
g(planet) = (6.67 * 10^(-11) * 3 * 5.972 * 10^24) / (5 * 6.371 * 10^6)²
g(planet) = 1.18 m/s²
Therefore ratio of acceleration due to gravity on the surface of the planet, g(planet) to acceleration due to gravity on the surface of the planet, g(earth) is:
g(planet)/g(earth) = 1.18/9.8 = 0.12
Some words that have changed meaning due to technological advances are dial, type, tweet, drone, and spam.
The circuit change when a wire is added is, an open circuit occurs and makes all bulbs turn off.
<h3>What is a closed circuit?</h3>
A closed circuit is a type of circuit connection in which the wire connection is complete and current flow occurs, turning the light bulbs on in the process.
<h3>What is an open circuit?</h3>
An open circuit is a type of circuit connection in which the wire connection is incomplete and current cannot flow, turning off the light bulbs.
Thus, the circuit change when the wire is added is, an open circuit occurs and makes all bulbs turn off.
