I think the answer is the sun
Answer:
Ein: 2.75*10^-3 N/C
Explanation:
The induced electric field can be calculated by using the following path integral:
Where:
dl: diferencial of circumference of the ring
circumference of the ring = 2πr = 2π(5.00/2)=15.70cm = 0.157 m
ФB: magnetic flux = AB (A: area of the loop = πr^2 = 1.96*10^-3 m^2)
The electric field is always parallel to the dl vector. Then you have:
Next, you take into account that the area of the ring is constant and that dB/dt = - 0.220T/s. Thus, you obtain:
hence, the induced electric field is 2.75*10^-3 N/C
Answer:
The temperature raise is = 0.14 [C]
Explanation:
In order to find the temperature difference we must use the following equation:
But first we need to find the original volume V:
When the volume is increased the diameter will be larger:
D1 = 0.125[m] + 0.0002[m] = 0.1252[m]
Therefore the new radius will be:
r1=0.0626[m]
The new volume is:
Replacing all the calculated values in the equation:
B)comet nuclei are not uniform in composition
Answer:
while all of the world can experience a solar eclipse it is not normally at the same time so one part of the earth might have it but not the other and even in one area if there is one in north america like the last one in texas we did not have a full eclipse
