1. Why is Earth more suitable for life than Venus?

1 answer:

6 0

Earth is more suitable because it has an atmosphere that is suitable for life, Earth has fresh water, and it is the safest distance from the sun. Plants increase the viability of life by producing Oxygen for animals and using carbon dioxide for photosynthesis. Volcanoes are present because of the pressure built up in the core of these planets. The inner planets are small in size compared to the outer planets. The temperature is much hotter and they are solid structures. Beyond Mars, these planets are gases and are much larger. There are many pictures and telescopes that explore the universe and show evidence of planets outside of the solar system.

A magnetic field is uniform over a flat, horizontal circular region with a radius of 1.50 mm, and the field varies with time. In

Daniel [21]

Answer: $81.57\mu V$

Explanation:

Given

radius of circular region r=1.50 mm

$A=\pi r^2=7.069\times 10^{-6}\ m^2$

Magnetic Field $B=1.50\ T$

time t=130 ms

Flux is given by

$\phi =B\cdot A$

change in Flux $d\phi =(B_f-B_i)A$

Emf induced is $e=\frac{\mathrm{d} \phi}{\mathrm{d} t}$

$e=\frac{(1.5)\cdot 7.069\times 10^{-6}}{130\times 10^{-3}}$

$e=81.57 \mu V$

Georgia [21]

The source of information was biased. It was like walking along a river bank in the country and asking everybody you meet whether they like fishing. Or asking 500 people sitting in the bleachers whether they like baseball.
I'm sure the scientist would have gotten different data if she interviewed 500 teenagers at neighborhood basketball courts, or 500 teenagers at a rock concert.
