Answer:
Will double
Explanation:
The total resistance of a circuit with n resistors in series is equal to the sum of the individual resistances:
In this problem, we have a circuit with initially one light bulb of resistance R, so the total resistance of the circuit is:
Later, a second identical bulb (so, same resistance R) is added in series to the circuit; so applying the previous formula, we see that the new total resistance is
So, the resistance has doubled.
Answer:
Landforms affect where people build houses and communities. Many people live on plains because it is easy to travel and to farm on flat land. Other people live in valleys, which are the land between mountains or hills. The soil in valleys is good for farming.
The force that will make this into
equilibrium would be equal to the force of equal amount yet applied on the
opposite direction.
<span>So we are given that a force of 55 N due west
was applied, so the equilibrium force would be 55 N due east.</span>
Answer:
a. Approximate umber of atoms = 10¹¹
b. number of atoms = 50 atoms thick
Note: The question is missing some parts. The complete question is as follows; Calculate the approximate number of atoms in a bacterium. Assume that the average mass of an atom in the bacterium is ten times the mass of a hydrogen atom. (Hint: The mass of a hydrogen atom is on the order of 1×10⁻²⁷ kg and the mass of a bacterium is on the order of 1×10⁻¹⁵ kg)
Explanation:
a. Approximate umber of atoms = mass of bacterium / 10 * mass of hydrogen
number of atoms = 10⁻⁵/ 10 × 10⁻²⁷
number of atoms = 10¹¹ atoms
b. The cell membrane is 10-8 m thick while the hydrogen atom has a diameter of 10-10 m.
The number of atoms in the cell membrane = d1 / 2 × d2
where d1 = diameter of cell membrane; d2 = diameter of hydrogen atom
The number of atoms in the cell membrane = 10⁻ / 2 × 10⁻¹⁰ = 50 atoms
The independant variable is whats being changed. The dependant variable responds to that change, and the control variable stays the same.
Hope that helps!!!
