Answer:
15 cm
Step-by-step explanation:
If we have two sides of a parallelogram in the ratio 5:4, then the other two sides must also be in the same ratio.
If the perimeter is 54, we can create the following equation regarding the length of each side
As our value for x is 3, and we know that the value for the larger side is 5x, we can simply plug in x to get the length of the larger side
Answer: The time taken for the mass to reduce from 50 g to 41 g is 6 years
Step-by-step explanation:
Expression for rate law for first order kinetics is given by
where,
k = rate constant
t = age of sample
a = let initial amount of the reactant
a - x = amount left after decay process
a) for completion of half life:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
b) for mass to reduce from 50 g to 41 g
The time taken for the mass to reduce from 50 g to 41 g is 6 years
