The solution is given below.
Step-by-step explanation:
Given that
Deposited amount = $1,500
Rate of interest = 5%
We need to find out the following things
a. The account after 4 years i.e. future value
As we know that
Future value = Present value × (1 + rate)^time period
Future value = $1,500 × (1 + 0.05)^4
Future value = $1,500 × (1.05)^4
Future value = $1,823.26
b. The account after 16 years i.e. future value
As we know that
Future value = Present value × (1 + rate)^time period
Future value = $1,500 × (1 + 0.05)^16
Future value = $1,500 × (1.05)^16
Future value = $3,274.312
c. The number of years that contain the amount of $2,000
Here
PV = $1,500
FV = $2,000
PMT = $0
RATE = 5%
The following formula should be applied
= NPER(RATE;PMT;-PV;FV;TYPE)
After applying the above formula, the time period is 4.94 years
d. The number of years that contain the amount of $2,500
Here
PV = $1,500
FV = $2,000
PMT = $0
RATE = 5%
The following formula should be applied
= NPER(RATE;PMT;-PV;FV;TYPE)
After applying the above formula, the time period is 8.77 years
The new pressure will be 8 kPa.
Explanation
Lets assume, the pressure of the gas is P and volume is V.
P is inversely proportional to V means : , where
is a proportional constant.
First, it is given that, Volume of hydrogen is 3.67 liter with a Pressure of 4 kPa
Now plugging V= 3.67 and P= 4 in the above equation:
Now, we are moving all of the hydrogen to a 1.835 liter container. That means now the Volume is 1.835 liter
Plugging V= 1.835 and k= 14.68 into the original equation ,
So, the new pressure will be 8 kPa.
