Answer:
Explanation:
The definition of angular velocity is as follows:
where 
is the angular velocity, and 
is the frequency.
Frequency can also be represented as:
where 
is the period, (the time it takes to conclude a cycle)
with this, the angular velocity is:
The period T of rotation around the sun 365 days, thus, the angular velocity:
if we want the angular velocity in rad/second, we need to convert the 365 days to seconds:
Firt conveting to hous
then to minutes
and finally to seconds
thus, angular velocity in rad/second is:
Answer:
3.974 Joule
Explanation:
Diameter of ring = 7.7 cm
a = Distance from the center = d/2 = 3.85 cm = 0.0385 m
Q = Charge = 5 mC
q = Charge to move = 3.4 mC
k = Coulomb constant = 9×10⁹ Nm²/C²
Work done will be equal to Potential energy when mass is at center
∴ Work to move a tiny 3.4 mC charge from very far away to the center of the ring is 3.974 Joule
Answer:
you need to consider the use for the product, how brittle the materials are, how they react to certain things, the cost of the materials, the durability and flexibility of the materials, and how easy to obtain the materials are as well as how they would work and how they would hold
