Answer:
C. mixture
Explanation:
A mixture is an impure substance. It has the following properties;
- It's composition is indefinite
- Their constituents retain their identities i.e. physical properties are retained
- Constituents react differently to changed conditions
- They can easily be separated into constituents by physical methods.
Granite is a rock. A rock is usually formed by a combination of different minerals.
Granite is made up of many compounds and so it is a mixture.
Every chemical "compound" is. Some examples of compounds include ...
Salt
Carbon dioxide
Alcohol
Water
DNA
Answer:
The force of static friction acting on the luggage is, Fₓ = 180.32 N
Explanation:
Given data,
The mass of the luggage, m = 23 kg
You pulled the luggage with a force of, F = 77 N
The coefficient of static friction of luggage and floor, μₓ = 0.8
The formula for static frictional force is,
Fₓ = μₓ · η
Where,
η - normal force acting on the luggage 'mg'
Substituting the values in the above equation,
Fₓ = 0.8 x 23 x 9.8
= 180.32 N
Hence, the minimum force require to pull the luggage is, Fₓ = 180.32 N
Answer:
135.3 cm + 93.46cm
= 228.76 cm
So total length of two fish is 228.76
In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. This law means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another.
