The components are at a right angle so the resultant is R^2 = 4.50^2 + 9.80^2 R = 10.78 or 10.8
I hope this helps! :)

Answer:
The ant
Explanation:
we know that the formula to calculate the work is: Fs
even though the elephant does exert force on a big tree, the distance it moved, which is s, is zero. F*s = F*0 = 0. It doesn't do work.
in contrast, the ant does exert force to drag a housefly, and it does move it, so it is doing work.
Answer: The orbital speed of the satellite is 4.214×10^4m/s
Explanation: Given:
Mass of Jupiter= 1.9×10^27Kg
Radius of Jupiter= 7.14×10^7m
Orbital speed of satellite is given by the equation:V = SQRT(G× M/ R)
But G= 6.673×10^-11Nm^2/Kg^2
V= SQRT (6.673×10^-11)×1.9×10^27)/7.14×10^7
V= SQRT1.776×10^9
V= 42,142.6515m/s=4.214×10^4m/s
Answer:
Explanation:
The net force is in the same direction of the acceleration. Acceleration changes the speed of an object.
D. Cm/s/s, which can be also written as cm/s^2. This is the only possible unit for acceleration from the above option as acceleration requires time to be squared.
