The atom must have gained 1 or more electrons or must have lost 1 or more electrons.
Answer:
A
Contact forces are forces that require the actual contact (touching) of two pieces of matter. ... A field force is a force that works at a distance. No touching is required. Gravity is a good example of a field force, because it works whether or not an object is touching something or touching nothing at all.
They are both good conductors if both heat and electricity due to the sea of delocalized electrons that is floating around without getting bonded to an atom.
Such electrons can flow around freely to conduct heat and electricity.
Answer:
70.4%
Explanation:
Step one:
given data
input energy= 2280J
output energy= 1,606 Joules of useful kinetic and 55joules waste
hence the useful out put= 1606J
Required
The efficiency of the motor
Step two:
what is the efficiency of a motor?
efficiency is the ratio of mechanical power delivered by the motor (output) to the electrical power supplied to the motor (input)
Efficiency= 1606/2280*100
Efficiency=0.704*100
Efficiency=70.4%
Answer:
f = 1 / [ 2*pi*R*C*Sqrt(2*N)
Explanation:
f = 1 / [ 2*pi*R*C*Sqrt(2*N) is the formula. Sorry I answered in English.
