Answer:
6hrs
Explanation:
t = time taken until the trains pass by each other/hrs
38 + 54 = 92
Use time = distance/speed:
t = 552/92 = 6
If the distance between two objects decrease and the masses of the objects remain the same, then the force of gravity between the two objects
<u>Answer:</u>
increases
Explanation:
The formula of gravitational force is given as:
F=G Mm/r^2
G = gravitational constant
M, m = Masses of two different objects in which the force is acting.
r = distance between both the objects.
As we can see from the formula that the force of gravity is inversely proportional to the square of the distance between both objects.
When the distance between both objects with the same masses decreases the gravitational force between them increases. Hence the correct answer is option B.
Illamends had the exact same answer from a similar question. Credit goes to her
It is p d day we’ll be together if it weighs 5kg you divide by the accelerated pace 400 dividdd by 400 is 45 and 500 divided by 500 is 75 answer is 75.
Ethology is the science of animal behavior.
Answer:
Explanation:
Weight will be highest at the pole where there is no tangential velocity requiring centripetal acceleration. Also, due to the slight bulge of the earth at the equator, the distance from the surface to the center of mass of earth is slightly shorter there meaning gravity is slightly stronger. Fg = GmM/R²
Weight will be lowest at the equator where the object is moving about the earth axis at an angular velocity of 2π/(24(3600)) rad/s ( about 7.27e-5 rad/s)
This means that some of the (already weaker, see above) gravity there is required to supply the needed centripetal acceleration to keep the object on the ground.
