In the equation for the gravitational force between two objects, the distance quantity or measurement must be squared. The formula for calculation the gravitational force between two objects is F = G*m1*m2/d^2. F is the gravitational force between the two objects. G is the constant gravity, m1 is the first object's mass, m2 is the second object's mass, and d is the distance between the two objects<span>.</span>
Yes, if weather was hot you need more fluids in your body due to the sweat pores needing to cool you down.
Answer:
a) the mass of the second car = 28000 kg
b) the amount of kinetic energy that was lost in the collision =
Explanation:
Given that:
mass of the train car = 6300 kg
speed of the train car = 12.0 m/s
mass of the second moving car = ???
speed of the second moving car = 2.2 m/s
After strike;
they both move with a speed = 4.00 m/s
a)
Using the conservation of momentum :
b)
To determine the amount of kinetic energy that was lost in the collision;
we will need to find the difference between the kinetic energy before the collision and after the collision;
i.e
Now; the kinetic energy that was lost in the collision is calculated as follows:
Answer:
Explanation:
Opposite magnetic poles tend to get closer. Hence, you may know how are the magnetic poles of the magnet B if you observe which poles try to get closer to the magnetic poles of the magnet A.
For example, if a pole of the magnet B is attracted by the south magnetic pole of the magnet A, that pole of the magnet B is a positive magnetic pole.
I hope this is useful for you
