Answer:
Quantity of charge = 1800 Coulombs
Explanation:
Given the following data;
Current = 1 A
Time = 0.5 hours
Conversion:
1 hour = 60 * 60 = 3600 seconds
0.5 hour = 0.5 * 3600 = 1800 seconds
To find the charge passing through the wire;
Mathematically, the quantity of charge passing through a conductor is given by the formula;
Quantity of charge = current * time
Substituting into the formula, we have;
Quantity of charge = 1 * 1800
Quantity of charge = 1800 Coulombs
Answer:
When something is heated, its atoms vibrate. If one end of a metal bar is heated, the atoms at that end vibrate more than the atoms at the cold end. The vibration spreads along the bar from atom to atom. ... Metals are good conductors of heat.
Explanation:
If a material blocks gamma radiation, then it will probably protect against alpha and beta radiation. Alpha particles are large and slow-moving, thus having very little penetrating power. Beta particles are fast-moving, and can penetrate the human flesh up to 1 or 2 centimeters. Gamma particles, however, have great penetration and can easily pass through the human flesh.
<h2>The option ( c ) is correct </h2>
Explanation:
As the frequency of oscillation of any oscillator is doubled
The velocity of sound v = νλ
here ν is the frequency and λ is the wavelength
Now if ν becomes double , the wavelength λ becomes one half . The velocity of sound remains the same in the same medium .
Thus option ( c ) is correct
You would have to subtract the mass number with atomic number which will give you 119 number of neutrons.
