Answer:
a. Electric field lines can never cross each other.
d. Wider spacing between electric field lines indicates a lower magnitude of electric field.
Explanation:
a. The electric field lines cannot be crossed, since this would mean that there would be more than one electric field vector for the same point at the place where the crossing occurs.
d. The space between the field lines is inversely proportional to the intensity of the electric field.
Answer:
V=f×λ
Where,
V is the velocity of the wave measure using m/s.
f is the frequency of the wave measured using Hz.
λ is the wavelength of the wave measured using m.
transform 46 cm in m = 0.46m and there u have it
Explanation:
The piano strings<span> for </span>low notes<span> are heavier, </span>have<span> more inertia, and </span>vibrate<span> at a lower frequency a lower pitch than lighter </span>strings<span> of the same </span>string<span> tension. Loudness involves how hard the keys are struck, which affects the amplitudes of the </span>vibrating strings<span>. the touch sensitivity of the </span>piano<span> distinguishes it from earlier.
Do you undertand?????

Hello!
During the forging process for a steel sword, when the blacksmith places a hot iron blank into a cold bucket water A) The water molecules move faster.
The iron blank molecules are at a higher temperature and move faster than the water molecules, which are colder. When the blacksmith places the hot iron blank into the water bucket, heat is transferred from the hot iron blank to the cold water causing water molecules to move faster, as their temperature (and kinetic energy) increases. This is described by the Second Law of Thermodynamics.
It's highly reactive and contains only one valence electron
