Just a guess without asking Google, that without the sun's gravity holding us in orbit, we would end up drifting whatever direction we were headed as it disappeared?
Answer:
A) 50.0 g Al
Explanation:
We can calculate the temperature change of each substance by using the equation:
where
Q = 200.0 J is the heat provided to the substance
m is the mass of the substance
is the specific heat of the substance
Let's apply the formula for each substance:
A) m = 50.0 g, Cs = 0.903 J/g°C
B) m = 50.0 g, Cs = 0.385 J/g°C
C) m = 25.0 g, Cs = 0.79 J/g°C
D) m = 25.0 g, Cs = 0.128 J/g°C
E) m = 25.0 g, Cs = 0.235 J/g°C
As we can see, substance A) (Aluminium) is the one that undergoes the smallest temperature change.
Out of the choices given, the best choice to explain the direction of the moving force of air is from area o high pressure to areas of low pressure.
If the Earth's axis were closer to "straight up and down" than
the present 23.5°, then . . .
-- The areas around the north and south poles where the sun
can be up or down for more than 24 hours would be smaller.
-- The "Tropic Zone", between the Tropic of Cancer and the
Tropic of Capricorn, where it's possible for the sun to be
directly overhead, would be narrower.
-- There would be less difference, everywhere, between the
lengths of daylight on the "longest day" and the "shortest day"
of the year.
-- The seasons would be less extreme everywhere. There would
be less difference, everywhere, between the coldest part of the
Winter and the warmest part of the Summer.
Answer:
Hey
The rope isn't moving because each boy is pulling with the same force on opposite ends. That being said the bot pulling force is balanced.
Inside the rope are molecules connecting the whole thing together. The force they exert on each other must be equal because they aren't moving but are still exerting forces
