To solve this problem, apply the concepts related to the centripetal acceleration as the equivalent of gravity, and the kinematic equations of linear motion that will relate the speed, the distance traveled and the period of the body to meet the needs given in the problem. Centripetal acceleration is defined as,
Here,
v = Tangential Velocity
r = Radius
If we rearrange the equation to get the velocity we have,
But at this case the centripetal acceleration must be equal to the gravitational at the Earth, then
The perimeter of the cylinder would be given by,
Therefore now related by kinematic equations of linear motion the speed with the distance traveled and the time we will have to
Therefore the period will be 44.9s
Answer: The force of attraction that holds two molecules is a chemical bond
Explanation:
What is Chemical bonds?
Chemical bonds are forces that hold atoms together to make compounds or molecules.
Types of chemical bonds
Chemical bonds include
1.covalent,
2. polar covalent, and
3. ionic bonds.
Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds.
To solve this problem it is necessary to apply the concepts related to Ohm's Law to find the voltage in the case of direct current. While for the Alternate current we use the concept of RMS voltage.
PART A) In the case of DC we have to,
V=IR
Where,
I = Current
R = Resistance
Where the current is 60mA y the resistance is , then the potential would be
In the case of DC we have that the current and the RMS voltage is,
The potential in AC then is,
