Answer:
500 gm
Explanation:
There may be some typos in your question post, here is my best guess of what you posted:
2.5 kg / 5000 kg /m^3 = .0005 m^3 water displacement
.0005 m^3 = 500 cm^3 for water this equals 500 gm
Answer:
dx = - 0.0789[m]
Explanation:
In order to solve this problem, we must remember that the vertical component of a vector can be determined using the opposite catheter of the right triangle, by means of the sine function.
Since the component is directed down, the sign is negative.
dx = - 0.0789[m]
Answer:D.
The force and displacement are in the same direction
Explanation:for work to be done,force and displacement must be in the same direction
Answer:
20.96 m/s
Explanation:
Apply the kinematic equation:
Vf=Vi+at
Vi=8m/s
a=1.8m/s^2
t=7.2s
Putting this all in should give you your answer of 12.96m/s
