The gravitational force of two objects, by definition, is given by:
Where,
G: gravitational constant
m1: mass of object number 1.
m2: mass of object number 2.
d: distance between both objects.
Therefore, according to the given equation, a change that always results in an increase in gravitational force is:
Increase in the mass of the objects and decrease in the distance between them.
Answer:
A change that will always result in an increase in the gravitational force between two objects is:
Increase in the mass of the objects and decrease in the distance between them.
Answer:
When you rub your hands together, the entropy of the universe increases. This increase in entropy is a result of the second law of thermodynamics, which states that in any energy transfer or transformation, the total entropy of an isolated system will always increase over time.
In this case, when you rub your hands together, you are converting some of the ordered kinetic energy of your hand motion into thermal energy (heat) due to friction. This process increases the randomness and disorder of the particles involved, including the molecules in your skin and the surrounding air. As a result, the overall entropy of the system, which includes your hands, the air, and everything else involved, increases.
So, the act of rubbing your hands together leads to an increase in entropy in the universe, consistent with the second law of thermodynamics.
Explanation:
The train will pass the 1500.0m marker 33.33 seconds after leaving the station. Its velocity is 162.0 km/h.
To find the time it takes for the train to pass the 1500.0m marker, we can use the formula: time = distance / velocity. Plugging in the values,
time = 1500.0m / 45.0 m/s
time = 33.33 seconds.
To convert the velocity from m/s to km/h, we use the conversion factor: 1 m/s = 3.6 km/h. Therefore,
velocity = 45.0 m/s * 3.6 km/h/m/s
velocity = 162.0 km/h.
In summary, the train will pass the 1500.0m marker approximately 33.33 seconds after departing the station, and its velocity will be 162.0 km/h

Answer:
119.88 km/h
Explanation:
1500/45=33.3
use a m/s to km/h calculator
put in 33.3 for m/s and you will get 119.88 km/h.
119.88 km/h.
O False
Answer:
True
Explanation:
In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Such forces often cause one object to speed up (gain momentum) and the other object to slow down (lose momentum).
