Answer:
c) 22,920 years
Explanation:
The half-life of C-14 is 5730 so in 5730 years , amount of C-14 is reduced to half.
In 5730 x 2 years , the amount of C-14 is reduced to 1/4 .
In 5730 x 3 years , the amount of C-14 is reduced to 1/8 .
In 5730 x 4 years , the amount of C-14 is reduced to 1/16 .
In 22920 years , the amount of C-14 is reduced to 1/16 .
So the answer is 22920 years.
Answer:
Explanation:
The air pressure inside a car tire is 3 atm = 303975 Pa
The force of 41,500 N of force pushing out on the tire.
We need to find the surface area of the inside of the tire. The pressure acting on an object is given by :
So, the surface area of the inside of the tire is .

<h3>
Answer:</h3>
80 kgm/s
<h3>
Explanation:</h3>
<u>We are given;</u>
- Mass of the Canoe is 32 kg
- Speed of the Canoe is 2.5 m/s
We are required to calculate the momentum of the Canoe?
- We need to know that momentum is the product of mass of an object and its speed.
Momentum = Mass × speed
Therefore;
Momentum = 32 kg × 2.5 m/s
= 80 Kgm/s
Thus, the momentum of the Canoe is 80 kgm/s.
