If the absolute pressure of a gas is 550.280 kPa, its gage pressure is
<span>
a. 101.325 kPa.
b. 448.955 kPa.
c. 651.605 kPa.
d. 277.280 kPa.</span>
The answer is B.
Answer:
Explanation: This is a type of radioactive decay and all the radioactive process follow first order kinetics.
Half life is the time required to decompose half of the reactants. thus after every half life the reactant will decompose to half of its present value.
Now, to calculate the number of half lives, we use the formula:
where,
a = amount of reactant left after n-half lives = ?
=Let Initial amount of the reactant = 100 g
n = number of half lives
Answer:
No getting rid of fossil fuel is not at all possible.
Explanation:
Dream of 100% renewable energy is possible through electrification and use of energy from sun, water and wind. Since, the high production cost of power plant for extracting energy from these sources in itself is a big challenge and hence decarbonized energy in current scenario is not realistic.
The answer is C. Gravitational potential energy is a function of the weight and the height of an object.
