Answer: heavy objects will have a higher terminal velocity than light objects. ... It takes a larger air resistance force to equal the weight of a heavier object. A larger air resistance force requires more speed.) Therefore, heavy objects will fall faster in air than light objects.

If the force between the puffed rice pieces is 4 x 10^-23 N when the pieces are 0.03 m apart, what is the charge on each of the
ycow [4]

2 x 10⁻¹⁸ C is the charge on each of the pieces.

<h3>What is the charge?</h3>

In physics, Charge is electric charge, electrical charge, or electrostatic charge and symbolized as q, is a characteristic of a unit of matter that expresses the extent to which it has more or fewer electrons than protons.

According to the question,

Fс = 4 x 10⁻²³ N

d = 0.03 m  , k = 9.0 x 10⁹ N·m²/C²

q =?

The force exerted by one charge q on another charge Q a distance r away is given by:

Coulomb's law:

Fc =\frac{kq_{1} q_{2} }{d^{2} }

By solving the equation:

q1q2 =\frac{F_{c} d^{2} }{k}

\frac{(4*10^{-23}(0.03m )^{2} }{(9.0*10^{9}N.m^{2}/C^{2})  }

= 4 x 10 ⁻³⁶C²

This is the square of the charge on the pieces of puffed rice.

Now, to find the charge on one piece of puffed rice,

take the square root of this number.

q = √4 x 10⁻³⁶ C²

q = 2 x 10⁻¹⁸ C

Therefore,

The charge on each of the pieces is 2 x 10⁻¹⁸ C

For a circuit find the total potential differences if two resistors
stepan [7]

-- If the two resistors are connected in series, then they behave like a single resistor whose resistance is (R₁ + R₂) ohms.

-- For any resistance, the potential difference (volts) across the resistance is   V = (current) x (resistance) .

-- So in THIS circuit,  <em>V = I x (R₁ + R₂)</em> .

An electromagnetic wave is propagating towards the west. At a certain moment the direction of the magnetic field vector associat
-BARSIC- [3]

Answer:

either +z direction or -z direction.

Explanation:

The direction of the electric field, in an electromagnetic wave always is perpendicular to the direction of the magnetic field and the direction of propagation of the wave.

You assume a system of coordinates with the negative x axis as the west direction, and the y axis as the up direction

In this case, the wave is propagating toward the west (- x direction), and the magnetic field vector points up (+ y direction), then, it is mandatory that the electric field vector points either +z direction or -z direction.
