Centripital acceleration. When an object moves in a circle, centripital acceleration acts to accelerate the object towards the center of that circle
Answer:
um d. but I am guessing this ans
Answer:
Stars create new elements in their cores by squeezing elements together in a process called nuclear fusion.
Explanation:
Answer:
450 joules ; 450 joules ; 45.9 m
Explanation:
Given that :
Initial Velocity, u = 30m/s
Mass, m = 1 kg
Kinetic Energy of ball (KE) = 0.5mu²
K. E = 0.5 * 1 * 30^2
K.E = 0.5 * 900
K.E = 450 Joules
B.) Potential Energy (P. E)
P. E = mgh
At the highest point, all kinetic energy has would have become potential energy, hence
K. E = P. E = 450 Joules
C) Height of the ball :
From ; P. E = mgh
Where ; g = acceleration due to gravity = 9.8m/s² ; h = height
450 = 1 * 9.8 * h
450 = 9.8h
h = 450 / 9.8
h = 45.918
h = 45.9 m
Answer: The answer would be C. When Octopus eject the water out, the water acts with an equal force on the octopus in opposite direction.
Explanation:
An octopus propels itself forward in the water by ejecting water backward through a funnel in its body.
Hope this helps! :D
