The cart with the least amount of mass will result in the fastest acceleration.
A volt-ampere is the product of the voltage and the current (measured in amperes) of the electricity on a line. Voltage is electric potential difference in charge between two points in an electrical field. it is measured in volts. while the Current is the flow of electrical charge which is often carried by moving electrons in a wire or a conductor. Current is measured in Amperes.
<span>element X has 62 neutrons
The atomic number of an atom is the number of protons that atom has. And the mass number of an atom is the sum of the number of protons and neutrons an atom has. So to determine the number of neutrons, simply subtract the atomic number from the mass number. So
89 - 27 = 62
So element X has 62 neutrons.</span>
