Answer: a) see attach file; b) E=0; c)E=-1.65* 10^6 N/C
Explanation: In order to solve this problem we have to use the gaussian law which is given by:
∫E*dr=Q inside/εo
E for r=8 cm is located inside the conducting shell so E=0.
For r=13 cm we have to use above gaussian law considering the total charge inside a gaussian surface with radius equal to 0.13 m. ( see attach)
Answer:
P = 942.54 W
Explanation:
Given:
Temperature, T = 310 K
mass, m = 70 kg
Now from the stefan's law,
we have the formula
P = σAT⁴
where,
P = radiate energy
σ = Stefan's constant = 5.67 × 10⁻⁸ W/(m² K⁴)
A = Area of the body
Average surface area for a human body = 1.8 m²
T = Temperature
on substituting the values we get,
P = 5.67 × 10⁻⁸ × 1.8 × 310⁴
or
P = 942.54 W
Answer:
After a male ejaculates, many sperms move to the upper vagina (via contractions from the vagina) through the cervix and across the length of the uterus, reaching the fallopian tubes. Here they will meet the egg cell ready to be fertilized
If Sofia weighs 50 lbs on Earth, then she would weigh 8.3 lbs, because you are 6 times lighter on the moon than you are on Earth!
