Why are jovian planets so much larger than terrestrial planets?

Physics

Explanation:

The temperature in the inner solar system was too high for light gases to condense, while in the outer solar system, the temperature was much lower, which allowed the Jovian planets to form, which grew enough to accumulate and retain the hydrogen gas that remained in the solar nebula, which led to its high levels of hydrogen and large size.

What happens to the gravitational attraction between 2 objects

amm1812

Answer:

It decreases.

Explanation:

between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases

The pressure gauge shown below has a spring for which k = 60 N/m, and the area of the piston is 0.50 cm2. Its right end is conne

Answer:

0.025 m

0.059166 m

Explanation:

P = Pressure

A = Area

x = Compression of spring

Force is given by

$F=PA\\\Rightarrow F=30000\times 0.5\times 10^{-4}\\\Rightarrow F=1.5\ N$

From Hooke's law

$F=kx\\\Rightarrow x=\dfrac{F}{k}\\\Rightarrow x=\dfrac{1.5}{60}\\\Rightarrow x=0.025\ m$

The spring is compressed 0.025 m

In the second case

$F_1=1.5\ N$

$F_2=101000\times 0.5\times 10^{-4}\\\Rightarrow F_2=5.05\ N$

Net force would be

$F=F_2-F_1\\\Rightarrow F=5.05-1.5\\\Rightarrow F=3.55\ N$

Compression would be

$x=\dfrac{F}{k}\\\Rightarrow x=\dfrac{3.55}{60}\\\Rightarrow x=0.059167\ m$

The compression of the spring is 0.059166 m

Which of these is NOT a possible type of energy transformation?

Leona [35]

It would be A because Light energy can't be used to make a Nuclear Weapon.
Electricity turns on a light bulb so B is scientifically correct.
If potential energy can be turned to Kinetic, it can also be switched. so C is scientifically correct
Ever heard of Geothermal power plants? So D is scientifically correct.
Meanwhile, A is impossible. so it is the answer you want to choose. Because the question asked for the one which is impossible.
