Answer:
In my knowledge
Option B. Lava flowed from the moon
and I am pretty sure cause I have read about it and option B is the conclusion I came with lol :D
Answer:
C)0.59 N
Explanation:
By the Achemides principle we know that the buoyancy force on an object which is immersed in a incompressible fluid at rest is equal to the weight of the fluid displaced. So all we have to do is to find the mass of 60ml.
Density = mass / volume
Mass = density × volume
= 1 g/cm³× 60 cm³
{ as 1ml=1cm³}
= 60 g
So force equals to,
Force = weight = mass × gravitational acceleration
= 0.06×9.8 = 0.59 N
Mass
I believe mass is the correct answer
Answer: Time to reach max. height is the time taken by it to reach the topmost position whereas time of flight is the overall time taken by it, i.e. till it reach down back to the thrower or launcher. And also time of flight is double the time to reach maximum height.
Explanation:
"Acceleration" means the rate at which velocity is changing.
If velocity is constant, then it isn't changing.
If velocity isn't changing, then acceleration is <em>zero</em>.
