That's true...
anaerobic has to do without involving oxygen
Answer:
B
Explanation:
A detailed solution to the problem is shown in the image attached. You could study it. The half life, and percentage of C-14 compared to present living sample was given as 13% of that of a living sample.
Answer:
-60.82 m/s²
Explanation:
recall that the acceleration due to gravity, g = 9.81 m/s²
We must also realize that during the car crash, the moving car is being brought to a stop. Hence, it is actually a deceleration (i.e a negative acceleration)
Therefore we must add a negative sign to our acceleration to describe the deceleration.
acceleration = - 6.2g
= -6.2 x 9.81 m/s²
= -60.8 m/s²
Answer:
Chemical potential energy is the energy stored in the chemical bonds of a substance. The various chemicals that make up gasoline contain a large amount of chemical potential energy that is released when the gasoline is burned in a controlled way in the engine of the car. The release of that energy does two things
Explanation:
The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.
