The amount of matter contained in a given volume for a substance is called density. The correct answer is density.
Density is a physical property of matter that describes how much mass is present in a given volume. It is typically expressed in units such as kilograms per cubic meter (kg/m³) or grams per milliliter (g/mL).
The density of a substance is determined by its mass and volume and can be used to identify and compare different materials.
Therefore, The amount of matter contained in a given volume for a substance is called density. The correct answer is density.

Answer:
Density
Explanation:
The amount of matter in a substance is its mass. In order to calculate the amount of matter in a given volume of a sample, you will use the density equation: density = mass/volume. ... The density of the elements are known and can be looked up in charts.
B-All radios and televisions should be switched off

A. 5
B. 3
C. 7
D. 4
Answer:
Option B
3
Explanation:
The two dimensions have the following significant numbers
4.56- 3 significant numbers
5.668- 4 significant figures
When responding, we give area as per the most precise number given hence the smallest (most precise) significant figures in these two numbers is 3. Therefore, the area will be given to 3 significant figures ie
4.56*5.668=25.84608 square meters
Area=25.8 square meters
Answer: 450 J
Explanation:
Kinetic Energy = 1/2 × mass × velocity²
Kinetic Energy = 1/2 × 1.0 Kg × 30 m/s²
Kinetic Energy = 1/2 × 1.0 Kg × 900
Kinetic Energy = 450 J
b rolling ball going down a hill
c moving car
d orbiting satellite
Explanation:
Simple harmonic motion requires a restoring force.
Simple harmonic motion should be periodic.
Option A:
When a rubber band is stretched,the internal forces of the rubber band pulls the band inside.So,internal forces are the restoring forces in a rubber band.
The motion is periodic as well since the the rubber band makes to an fro motion expanding ans contracting.
So,this performs SHM.
Option B:
There is no restoring force and no periodicity.
So,this is not SHM.
Option C:
There is no restoring force and no periodicity.
So,this is not SHM.
Option D:
There is periodicity but no restoring force.
So,this is not SHM.
