The density of the liquid is 0.98 g/mL
<h3>What is density? </h3>
The density of a substance is defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as:
Density = mass / volume
With the above formula, we can obtain the density of the liquid.
<h3>How to determine the density </h3>
- Mass = 30.8 g
- Volume = 31.5 mL
- Density =?
Density = mass / volume
Density of liquid = 30.8 / 31.5
Density of liquid = 0.98 g/mL

Answer: When you turn a light on it becomes bright :)
In electrical wiring, a light switch is a switch most commonly used to operate electric lights, permanently connected equipment, or electrical outlets. Portable lamps such as table lamps may have a light switch mounted on the socket, base, or in-line with the cord. Manually operated on/off switches may be substituted by dimmer switches that allow controlling the brightness of lamps as well as turning them on or off, time-controlled switches, occupancy-sensing switches, and remotely controlled switches and dimmers. Light switches are also found in flashlights, vehicles, and other devices.

Question:
Leon made a study chart about human-induced changes to the environment.
Environmental Changes Caused by Humans
X Y
Results from introducing harmful substances into the environment
Example: oil spill
Results from natural areas being cleared and replaced by human development
Example: deforestation
Which headings best complete the chart?
X: Habitat Destruction
Y: Pollution
X: Long-Term Changes
Y: Short-Term Changes
X: Short-Term Changes
Y: Long-Term Changes
X: Pollution
Y: Habitat Destruction
Answer:
X: Pollution
Y: Habitat Destruction
Explanation:
From the above question, Leon gave us two variables, X and Y.
The human induced changes were divided into two.
1. Results from introducing harmful substances into the environment
Introducing harmful substances into the environment is also called pollution. And we can represent this as X which is the first variable.
2. Results from natural areas being cleared and replaced by human development.
This description given in number two above whereby land areas are been cleared and replaced by human development has a negative effects on the environment because the vegetation which includes the trees are been cut down and living organisms(animals) will go extinct gradually. This act affect the balance of the ecosystem and it can be referred to as the destruction of the habitat of living organisms
Therefore, the correct headings best complete the chart is :
X: Pollution
Y: Habitat Destruction
First, let's explain the variables. F means force, m means mass, and a means acceleration. F is measured in Newotns [N], mass is measured in kilograms [kg], and acceleration in measured in meters per squared second [m/s²].
Now let's mover on the first problem.
Given
m = 1000 kg
a = 3 m/s²
According to the second law of Newton, the force is equal to the acceleration multiplied by the mass.
The answer is 3000 N.
The second problem is smiliar.
Given
m = 70 kg
F = 250 N
We use the same formula from before, and use a bit of algebra to adapat it to our needs.
The answer is 24 1/7 s/m^2.
Answer:
To find the volume of the gas. So if you have the amount of gas in moles. So the first step is to multiply the amount of moles that is 2.4 with liters to find the answer.
