Answer:
Zero...
Explanation:
When the glass road is rubbed with silk clothes, it get charged positively. When it made contact with the metallic rod, the positive charge is transferred to the metallic rod (The wooden post will have no effect because it doesn't interact with charge on metals). When the metallic rod make contact with ground with intact glass rod, all the charge transfers to the ground because of the high negative potential of Earth, So, in the end all the net charge become zero.
Answer:
The smallest integer is n = 4
Explanation:
Using the equation V= Sqrt(F/Linear density)
V= Sqrt(341/0.0120)
V= Sqrt(28416.7)
V= 168.57m/s
Path distance =[ (n +1)/2]lambda
But V= f(Lambda)
n lambda/2 =L
n = f2L/V
n = (20 × 2 × 16.86) / 168.57
n = 4.0007
The smallest integer is n= 4
Transmission electron microscope
Answer:
Explanation:
Given the following data;
Mass = 2kg
Energy = 50J
Height = 10m
To find the speed
Kinetic energy can be defined as the energy possessed by a body due to its motion.
K.E = ½mv²
Substituting into the equation, we have;
50 = ½*2*v²
V² = 50
Taking the square root of both sides, we have;
V = 7.07m/s
