Answer:
this happens because there is gravitational force acting upon it.
Answer:
C. 100
D.3
E. 33.3
Explanation:
C. Mechanical Advantage=Load / Effort
= 200N
--------
100N
Therefore,. = 100
D. I. Velocity Ratio= distance moved by the effort / distance moved by load
= 30cm/10cm
= 3
II. Efficiency= M.A / V.R
= 100/3
= 33.33
Ya but what’s the following. there’s no options to choose between
<span>A: The table tennis ball represents the Milky Way and the volleyball represents the local group cluster.</span>
Answer:
b. 84 minutes
Explanation:
= Centripetal acceleration = 9.81 m/s²
r = Radius of Earth = 6378.1 km
v = Velocity
Centripetal acceleration is given by
Time period is given by
The time period of Earth’s rotation would be 84.43835 minutes
