This is true. Gravity is constantly pulling on anything and everything (even light!), no matter how far away it is from another object.
Answer:
A.
Explanation:
I think it’s a. Because, I normally think about how someone else feels if I want to say something.
acted upon a outside unbalance force.
Explanation:
Given data
velocity v= 25m/s
The time it takes to put on brake t= 0.3s
the distance covered when the brake was put on is
v=s/t
s= v*t
s= 25*0.3s
s= 7.5m
hence the distance covered is 7.5m
Also the rate of decrease in aceleration is 5m/s^2
we can also calculate the distance covered at this rate
v^2=u^2+2as
25^2= 0+2*5*s
625=10s
divide both sides by 10
s=625/10
s= 62.5m
The total distance covered between putting on the brakes and decelareation is 7.5+62.5= 70m
Given that the tree is 75m ahead, the car would not hit the tree
Focal distance of an ellipse is given by the formula
here a = length of semi major axis
e = eccentricity of the path
now here we know that
length of major axis for the path of planet is given as 32 units
so here we can say
so length of semi major axis is 16 units
focal distance for the planet path is given as 8 units
now from the above formula we can write
so eccentricity for the path of planet will be 0.5
