Explanation:
Total surface area of cylinder:

sheet of metal required = 120.95 cm^2
Answer:
$1.26
Explanation:
Power =energy/ time
energy =powerxtime
energy =50x31x24=37200
=37.2kwh
1kwh =3.39
37.2kwh=3.39x37.2=126.108cent
=$1.26
Answer:
If the force remains the same, the acceleration would decrease
Explanation:
According to Newton's second law, the acceleration of an object is given by

where
F is the force applied to the object
m is the mass of the object
As we see from the formula, the acceleration a is inversely proportional to the mass, m. Therefore, if the force F remains constant, this means that if the mass of the skateboarder increases, then the acceleration will decrease.
Momentum=mass × velocity
momentum= 200×30
=6000kgm/s
Chemical equation
Explanation:
A chemical equation is an expression that represents a chemical reaction. The formula of the reactants are connected by an arrow with the formula for the products.
Chemical reactions are made up of reactants and products which all together forms a chemical equation.
- The reactants are positioned on the left hand side of a chemical equation. It is the specie that forms the product.
- The products are on the right hand side and they are the result of a chemical change.
