Power=work/time
So,
Power =450/50=9watts
Answer:
or -0.000250 C
Explanation:
The field points downward, which is the direction of a positive charge. In order for the penny to rise, it has to have a negative charge since its direction is opposite that of the field.
To calculate the magnitude of the charge:
The penny is to accelerate upward so it must overcome gravity. Hence, the net force to cause it to accelerate it upward is the difference between the electrostatic force and its weight.
Now, the electric field intensity is given by
where q = charge
to 3 significant figures.
In standard form, q = The negative sign indicates it has a negative charge, as explained initially.
A customer is billed for a service or product, but it gets recorded in the ledger at a lower amount is an example of fraudulent bookkeeping on the income side. This fraud would likely happen in the account receivable department of a company which generates sales for its function<span>. The sale is the primary source of company's operational income.</span>
Answer:
The neutron is a subatomic particle, symbol
n
or
n0
, with no electric charge and a mass slightly greater than that of a proton. Protons and neutrons constitute the nuclei of atoms. Since protons and neutrons behave similarly within the nucleus, and each has a mass of approximately one atomic mass unit, they are both referred to as nucleons.[6] Their properties and interactions are described by nuclear physics.
