Answer:
The following is the relation between electric force and field
Explanation:
Electric force is the magnitude of electrostatic forces between two charges which is directly proportional to product of both charges and inversely proportional to the square of the distance between them.
Here k is the coulumb's constant.
Where as the electric field is the electric force per unit charge. It is the function of electric force. It is the vector quantity and its direction is taken radially inward or outward depending on the nature of charge.
Its equation is
Electric Field
Electric Field units are in volts where as Electric force units are newtons.
I think the best answer is: poor driving attitude. If you have a poor attitude, you can make mistakes, such as risky chances or bad choices. The other options might be annoying, but they won't make you make mistakes unless you have a bad attitude.
Answer:
They all travel at the same speed
Explanation: the speed of light — in a vacuum, but when they come into contact with matter, they slow down. ... Opaque objects transmit little or no visible light, translucent objects transmit some, and transparent objects transmit almost all, which is why we can see through them.
Answer:
Some work input is lost to friction
Explanation:
The efficiency of a machine is defined as:
(1)
where
is the work output
is the work input
Due to the law of conservation of energy, the work output can never be larger than the work input (because energy cannot be created). Moreover, in real machines part of the work input is lost due to the presence of frictions: as a result, part of the energy in input is converted into thermal energy or other forms of energy, and so the work output is smaller than the work input, and so the ratio (1) becomes less than 1, and so the efficiency is less than 100%.
