It is easier now to communicate with someone far away on another continent and even do business and shop online without been physically present at the other end. One of the most important modern means of communication is the internet which has turned the world to a small global village.
Answer: 1. Carbon dioxide is not an air pollutant
Explanation: it can be toxic and or safe
The answer is c capacitance
Answer:
4.32
Explanation:
The centripetal acceleration of any object is given as
A(cr) = v²/r, where
A(c) = the centripetal acceleration
v = the linear acceleration
r = the given radius, 1.9 m
Since we are not given directly the centripetal acceleration, we'd be using the value of acceleration due to gravity, 9.8. This means that
9.8 = v²/1.9
v² = 1.9 * 9.8
v² = 18.62
v = √18.62
v = 4.32 m/s
This means that, the minimum speed the cup must have so as not to get wet or any spill is 4.32 m/s
