Answer:
r = 22.3 cm
Explanation:
given,
angular speed = 45 rev/s
tangential speed = 63 m/s
length of the rotating string
angular velocity =
ω = 2 π N
ω = 2 π x 45
ω = 282.74 rad/s
we know,
v = r ω



r = 22.3 cm
They're both made of carbon.
Answer:
Being silent most of the time is a good virtue under certain circumstances and environment. It is always advisable to remain quite silent and not be too quick to respond to situations or issues so as to avoid making and saying wrong words.
The ethics in a workplace involves communicating with others with less amount of talking as possible and more of body languages and signs. This is because the workplace is meant to be a serene place.
Answer:
6 V
Explanation:
In a circuit, the relationship between voltage, current and resistance is given by Ohm's law:

where
V is the voltage
R is the resistance
I is the current
In this circuit, we have
is the resistance
I = 0.500 A
so we can find the voltage of the battery by using Ohm's law:
