Answer:
Explanation:
Charge of particle = q
The particles have same charge
r = Distance between charge
k = Coulomb constant =
m = Mass of particle = 10 mg
g = Acceleration due to gravity = 9.81 m/s²
Electrostatic force is given by
According to Newton's second law
Here, both the electrostatic and inertial force is conserved
The charge of the particles is
The charge of the particles is very low as compared to typical static electricity
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. It behaves exactly like a permanent magnet, like those magnets commonly used to stick items to our fridge.
To make a permanent magnet we need:
- One iron nail ( Could be fifteen centimeters (6 in) long
)
- Three meters (10 ft) of copper wire
- One or more D-cell batteries
To make the electromagnet, we need to:
1. Wrap the Wire Around the Nail
2. Connect the Battery
And you are all set!
Answer:
105000km
Explanation:
Given parameters:
Speed of shuttle = 21000km/hr
Time of travel = 5hrs
Unknown:
The distance covered by the space shuttle;
Solution:
Distance is the length of the path traveled.
Distance = speed x time
Input the parameters and solve;
Distance = 21000km/hr x 5hrs
Distance = 105000km
