The mass of Jupiter is 1.9 x 1027 kg.
Answer:
972 J
Explanation:
At the bottom, all the gravitational potential energy was converted into kinetic energy. If you calculate the GPE, its value will be the same that the KE at the bottom. The GPE can be calculated this way:
GPE = mass×gravity×heigth
GPE = 2.2×9.8×45.08 ≈ 972
Answer:
7.16 m /s
Explanation:
The depth of the small pipe attached with the side wall of tank from the surface of water
h =( 3.1 - .48 )m
= 2.62 m
velocity of flow of water= √ 2 g h
= √ 2 x 9.8 x 2.62
= 7.16 m /s

Answer:
256.3 N
Explanation:
Throughout the motion of the mass in the circular motion, the resultant of the Tension in the string and the weight of the body gives the net force (centripetal force) that is responsible for the acceleration of the mass in a circular motion.
At the top of the vertical circle of the motion of the mass, the tension is directed downwards towards the centre of the circle and the weight also is directed downwards towards the earth.
Net force = ma = T + W
ma = T + mg
But a = (v²/r) for circular motion,
(mv²)/r = T + mg
m = 2.31 kg
v = 7.77 m/s
r = 0.500 m
g = acceleration due to gravity = 9.8 m/s²
(2.31×7.77²)/0.5 = T + (2.31×9.8)
278.923 = T + 22.638
T = 278.923 - 22.638
T = 256.285 N = 256.3 N
Hope this Helps!!!
An absorption spectrum occurs when light passes through a cold, dilute gas and atoms in the gas absorb at characteristic frequencies; since the re-emitted light is unlikely to be emitted in the same direction as the absorbed photon, this gives rise to dark lines (absence of light) in the spectrum.
hope this helped :)
