Answer:
a) 1/4 what it is now
Explanation:
As we know that force of gravitation between two planets at some distance "r" from each other is given as
now since we know that if the distance between Earth and Sun is changed
So the force of gravity will be given as
now we know that the distance between sun and earth is changed to twice the initial distance between them
so we have
so new gravitational force between sun and earth is given as
Hello I’m not sure what the answer is but I just wanted to let you know that your an amazing person :)
Answer:
solid form
Explanation:
Heat is transferred by conduction in a solid form.
Speed: 15.3 m/s
Direction: north of east
Explanation:
In order to find velocity, we have to find the components along the east-west direction and the north-south direction first.
Along the east-west direction, we have
east
west
So the net velocity in this direction is
east
In the north-south direction, the net velocity is
north
So, the speed (which is the magnitude of the velocity) is
While the direction is given by
north of east.
