Answer:
The person is on the Moon having a weight of 500 N. The acceleration of gravity on the Moon is approximately 1.6 m/s2. What is your his, which includes his space suit?
f= Force (of gravity)=500N
g=acceleration of gravity=1.6m/s^2
m=mass=312kg
m=f/a= 500N/1.6 m/s^2 = 500 (kg-m/1.6m/s^2) = 500/1.6kg = 312kg
his mass is 312kg

Answer:
Not possible
Explanation:
 = longitudinal modulus of elasticity = 35 Gpa
 = longitudinal modulus of elasticity = 35 Gpa
 = transverse modulus of elasticity = 5.17 Gpa
 = transverse modulus of elasticity = 5.17 Gpa
 = Epoxy modulus of elasticity = 3.4 Gpa
 = Epoxy modulus of elasticity = 3.4 Gpa
 = Volume fraction of fibre (longitudinal)
 = Volume fraction of fibre (longitudinal)
 = Volume fraction of fibre (transvers)
 = Volume fraction of fibre (transvers)
 = Modulus of elasticity of aramid fibers = 131 Gpa
 = Modulus of elasticity of aramid fibers = 131 Gpa
Longitudinal modulus of elasticity is given by

Transverse modulus of elasticity is given by


Hence, it is not possible to produce a continuous and oriented aramid fiber.
 
        
             
        
        
        
Answer:
(a) The force between them quadruples
Explanation:
According to coulomb's law, initial force between the two charged objects is given as;

where;
k is coulomb's constant
q₁ is the charge on the first object
q₂ is the charge on the second object
r is the distance between the two objects
When the charges on both objects are doubled, then;
q₁ = 2q₁
q₂ = 2q₂
Force between the two charged objects will become
 
Therefore, the force between them quadruples
 
        
             
        
        
        
Catalytic ozone destruction occurs in the stratosphere where the reactions involving bromine, chlorine, hydrogen, nitrogen and oxygen gases form compounds that destroy the ozone layer. The reactions uses a catalyst (speeds up the reaction) in a two step reaction. considering chlorine the reactions appears as follows;
step 1
 Cl + O3 = ClO + O2 
 step 2
ClO + O = Cl + O2 
Where by chlorine is released to destroy the ozone layer, this takes place many times even with the other elements (hydrogen, bromine, nitrogen) and the end result is a completely destroyed Ozone layer
