Answer:
E=1760.93 cal
Explanation:
a) First we find the total time
t=x/v
t=189000/12.5
t=15120 seconds
Now we multiply the time by his total wattage
E=t*W
E=(15120)(6.5)(75)=7371000 joules
As,
1 joule = 2.389 x 10-4
So, in term of nutritional Calories
E=7371000 * 2.389*
E=1760.93 Cal
When we have two sound waves with frequencies f1 and f2 that interfere, the beat frequency is equal to the absolute value of the difference of the two frequencies, so in our problem:
Radioactivity is a nuclear phenomenon. It is the process of spontaneous emission of α (alpha particles) or β (beta particles) and γ (gamma particles ) radiations from the nucleus of atoms during their decay.
- Uranium and radium are the two radioactive substances.
