The answer is electron
Explanation: An atom consists of a small but massive nucleus that include protons (positive charge) and neutrons (neutral charge). around the nucleus is a cloud of rapidly moving electrons (negative charge)
Answer:
The magnitude of the magnetic field B is 5.921 T.
Explanation:
Given that,
Length = 4.1 mm
Current
We need to calculate the magnetic field
Using formula of magnetic field
Put the value into the formula
Hence, The magnitude of the magnetic field B is 5.921 T.
Answer:
D. power
Explanation:
kg represents mass
(m/v)² represents velocity squared
Then kg·m²/s² represents mass·velocity² = <em>kinetic energy</em> or <em>potential energy</em> or <em>work</em>.
kg·m²/s³ will be the <em>rate of doing work</em>, which is power
Answer:
yes
Explanation:
The metal is closer than 20 cm to the magnet which is in the magnetic field.
