30 grams of radioactive isotope have passed.
Muscle cells have to use a lot of energy and the Mitochondria is known as the "power house" of the cell... I would say the number of mitochondria needed is increased because more power and energy is being used in that cell than a normal one (idk if this helps or if that's the answer you were looking for)
Answer:

Explanation:
We can use the equation for the speed

where x is the distance and t the time. In this case we know that the time spent was 2 hours and the distance was 150km. By replacing we have

I hope this useful for you

Answer:
Electromagnetic
Explanation:
Electromagnetic waves are those waves that do not require any material medium for propagation. They arise from a vibration of electric and magnetic fields.
The electromagnetic spectrum is comprised of many waves. One of the waves in the spectrum is visible light.
Visible light is in turn composed of seven different wavelengths of which green light is one of them. Hence, green light travels by electromagetic wave.
Knowing the amount of force F and the length of time t that force is applied to an object will tell you the resulting change in its momentum ΔP . This is:
F*t = ΔP
ΔP = F*t <em>but ΔP = mv</em>
mv = F*t
v = F*t/m
v = 12000 N × 5 s / 2000 kg
<h3>v = 30 m/s</h3><h2 /><h2>A/ The initial speed of the car was 30 m/s</h2>
