Answer:
Animals cerate Carbon Dioxide through the process of respiration.
Answer:
The activity of cobalt-60 after 72 hours is 34.895 MBq
Explanation:
A(t) = Ao(0.5)^t/t1/2
A(t) is the activity of cobalt-60 after time t
Ao is the initial activity of cobalt-60 = 35 MBq
t is time taken to reduce in activity = 72 hours = 72/24 = 3 days
t1/2 is the half-life = 0.693 ÷ decay constant = 0.693 ÷ 0.001/day = 693 days
A(72) = 35(0.5)^3/693 = 35 × 0.5^0.00433 = 35 × 0.997 = 34.895 MBq
Force is defined as the push or pull applied to the body. Its unit is Newton. The net force will be 10 N on the right side.
What is force?
Force is defined as the push or pull applied to the body. Sometimes it is used to change the shape, size, and direction of the body. Force is defined as the product of mass and acceleration. Its unit is Newton.
The given data in the problem is;
F₁ is forced by person 1 = 100 N
F₂ is forced by person 2= 90 N
Fₓ is the net force
Fₓ = F₁ -F₂
Fₓ = 100-90
Fₓ= 10 N
Hence the net force will be 10 N on the right side.

The statement which best explains why when you trip, your foot stops, but your body continues to move forward is: A. An unbalanced force stops your foot but does not act on the rest of your body.
A force can be defined as a push or pull of an object or a physical body, which typically results in a change of motion due to the interaction of the object with another.
In Physics, there are two (2) main types of force and these are:
An unbalanced force occurs when two or more forces acting on an object or a physical body are not equal in magnitude and as such, it typically results in a change of motion.
In conclusion, when you trip, your foot stops, but your body continues to move forward because an unbalanced force stops your foot but doesn't act on the other part of your body.
