When you're talking about gravity, it's easy to identify the equal
opposite forces.
Gravity ALWAYS produces an equal pair of opposite forces.
They both act between the centers of the two objects, one in
each direction.
Consider the equal pair of opposite gravitational forces between
you and the Earth. One force acts on you, and draws you toward
the center of the Earth. We call that force "your weight".
The other one acts on the Earth, and draws it toward the center
of you. Hardly anybody ever talks about that one, but the two
forces are equal ... your weight on Earth is equal to the Earth's
weight on you !
Answer:
they are also close to the ring of fire and the south pole so..

Answer:
The wavelength of that line in the spectrum of a planet is .
Explanation:
Given that,
Wavelength
Velocity = 30 km/s
We need to calculate the wavelength of that line in the spectrum of a planet
Using formula of wavelength
Where, v = velocity of planet
c = speed of light
Put the value into the formula
Hence, The wavelength of that line in the spectrum of a planet is .
Answer:
a) three times greater
Explanation:
Remember the heat capacity is the necessary heat to increase the temperature 1 ºC to an specific mass of the substance, in this case since the water and the metal have the same mass, is easier to compare just the neccesary heat.
Since water increases 20 ºC and the metal 60 ºC, it was neccesary 3 times of the quantity of heat to the same amount of mass of the two different susbtances.
