Answer:
a) 
Explanation:
Given paraeters are:
R = 25 cm
d = 4.7 mm
f = 60 Hz
= 160 V
a) 
Where 
Hz and 
V
For 
Since 
From Ampere's Law:
where 
So at ,
For maximum B, cos(2πft) = 1. Hence,
T
b) From r = 0 to r = R = 0.025 m, by Ampere's Law, the equation will be:
From r = R = 0.025 m to r = 0.1 m, by Ampere's Law, the equation will be:
The plot is given in the attachment.
Answer:
Average speed = 1.2 m/s
Average velocity = 0.4 m/s
Explanation:
Average speed = total distance/total time
Average speed = (40 + 20)/(40 + 10)
Average speed = 60/50
Average speed = 1.2 m/s
Average velocity = displacement/time
Now, she ran 40 m south and ran 20 m back north which is in the direction of where she began the journey.
Thus;
Displacement = 40 - 20 = 20 m
Average velocity = 20/50 = 0.4 m/s
Inertia is the tendency of an object to resist changes in its state of motion.
Answer:
1. Nitrogen
2. Oxygen
3. Carbon dioxide
4. Water vapor
5. Ozone
Explanation:
The atmosphere composes of 78% nitrogen which occupies the largest percentage followed by oxygen which takes up 21%, Argon takes up 1% then other components such as water vapor occupy between 0-7% and ozone takes 0.0-0.01. Moreover, 0.01-0.1 is occupied by carbon dioxide. Therefore, the answers for 1-5 are as follows.
1. Nitrogen
2. Oxygen
3. Carbon dioxide
4. Water vapor
5. Ozone
