Answer:
a) P1=100kpa
V1=6m³
V2=?
P2=50kpa
rearranging mathematically the expression for Boyle's law
V2=(P1V1)/P2=(100×6)/50=12m³
b) same apartment as in (a) but only the value of P2 changes
=> V2=(100×6)/40=15m³
Explanation:
 since temperature is not changing we use Boyle's law. mathematically expressed as P1V1=P2V2

Answer:
Potential energy = 14.7 Joules. 
Explanation:
Given the following data;
Mass, m = 1kg
Height, h = 1.5m
We know that acceleration due to gravity is equal to 9.8m/s²
Potential energy can be defined as an energy possessed by an object or body due to its position. 
Mathematically, potential energy is given by the formula;

Where, P.E represents potential energy measured in Joules.
m represents the mass of an object. 
g represents acceleration due to gravity measured in meters per seconds square. 
h represents the height measured in meters.

Substituting into the equation, we have;

P.E = 14.7 Joules. 
 
        
             
        
        
        
A mutation in the DNA ca happen during growth, when the DNA splits and becomes RNA. Mutations can also occur from other invasive cells, such as bacteria or viruses. A mutation in your DNA can also be there from when you were born. These mutations can cause variations in your appearance, such as eye color, ability to see, taste, smell and the complexion of your face. The mutations can also result in variations in your growth, causing immature or late growth. These mutations are dangerous, and can result in failure of the organisms cells , to complete and utter death of an organism.
        
                    
             
        
        
        
Answer:
Sun heating a car sitting in a parking lot
Explanation:
The sun heating a car sitting in a parking lot is an example of electromagnetic waves transferring energy. 
- Electromagnetic waves are produced from the vibration between electric and magnetic fields. 
- These waves can be propagated through vacuum with no particles inside of them. 
- The sun produces electromagnetic radiation through the process of nuclear fusion. 
- These radiations are used to warm the earth surface. 
- The sun heating a car sitting a parking lot is one vivid example.
