Answer:
P.E = mgh
K.E = 1/2mv²
Explanation:
P.E = mgh
That is m= mass in kilograms, g=acceleration due to gravity and h= height in meters.
K.E = 1/2mv²
That is 1/2 of an object's mass multiplied by the velocity squared.
Answer:
Given:
Initial velocity of the asteroid, v = 19.9 km/s = 19900 m/s
(since, 1km = 1000 m)
Final velocity of the asteroid, v' = - 18.3 km/s = -18300 m/s
time period, T = 1.97 years
Solution:
(a). Total change in velocity, :
= v' - v
= - 18300 - 19900 = - 38200 m
here, negative sign is indicative of the fact that the motion of the asteroid is in the downward direction.
(b) Asteroid's average acceleration, a:
a =
a =
a =
Here, the negative sign is the indication of deceleration of the asteroid in the downward direction.
Hello,
Is this finding the linear speed and or/angular speed?
Answer:
Using the kinetic theory, explain the rise of water in a glass capillary tube. ... Glass and water are composed of different molecules. The force of attraction between the glass molecules and the water molecules is stronger than that among water molecules hence the rise of water in the tube.
Explanation:
its the specifics of science
The weight I 151.9 N because the weight equals the mass times the gravitational force
