Given Information:
Amplitude of the electric field = E = 570 N/C
Speed of light = c = 3.0x10⁸ m/s
Required Information:
Amplitude of the magnetic field = ?
Answer:
Amplitude of the magnetic field = 1.90x10⁻⁶ T
Explanation:
The relation between the amplitude of the electric field and magnetic field is given by
B = E/c
Where c is the speed of light
B = 570/3.0x10⁸
B = 1.90x10⁻⁶ T
Therefore, the amplitude of magnetic field is 1.90x10⁻⁶ T
Answer:
The atom becomes a positively charged ion.
Explanation:
- The building blocks of an atom are protons, neutrons, and electrons.
- The protons and neutrons present in the core of the atom are called nucleus.
- The electrons are scattered in an ordered way around the nucleus.
- The protons are positively charged and the electrons are negatively charged particles. The neutrons do not possess any charges.
- Binding energy is supplied to the atom to remove an electron.
- It is possible to remove the electrons of the lighter elements.
- When an electron is removed from the hydrogen atom. It becomes positively charged ion or simply proton.
- When all of the electrons are removed from the helium atom, it becomes a positively charged α particle.
- It is practically very difficult to remove all of the electrons from the heavier elements.
- When all of the electrons are removed from an atom it becomes an unstable positively charged ion.
Answer:
Watermelon is going at a speed of 
in downward direction
Explanation:
Given
- Height of the Empire State building = 320 m
- Speed of the superman = 24 m/s
since both the motion of both watermelon and the superman is under gravity. The acceleration of both is g in downwards direction. So the relative acceleration between them is zero and when they meet the relative distance covered by them will be the height of the Empire State building.
so let t be the time when they meet given by
Now let v be the velocity of the the watermelon when they meet given by
C coefficient is expressed in terms of joules divided by grams and celsius
