Answer:

D. You should prepare an emergency plan to cope with the disaster.

B. You should duck, cover, and hold.

Explanation:

Because Panic and stress are the main reasons that make the situation worse during natural disasters. Disasters are aggravated when people add chaos to the equation. It's important not to panic during an earthquake. You must maintain a rational state of mind so that you don't do something regretful out of fear.

A charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a th

Mila [183]

Answer:

$x = a + \frac{a\sqrt2}{\sqrt3 - \sqrt2}$

Explanation:

Position of charge 3q is x = 0

position of charge -2q is x = a

so here we know that

when two charges are of opposite nature then the electric field will be zero on the line joining the two charges at the position near to smaller magnitude charge

So here the electric field will be zero if the field due to 3q is counterbalanced by field due to -2q

so here we can say

$\frac{k(3q)}{(r+a)^2} + \frac{k(-2q)}{r^2} = 0$

$\frac{3}{(r + a)^2} = \frac{2}{r^2}$

$\frac{r+a}{r} = \sqrt{\frac{3}{2}}$

$1 + \frac{a}{r} =\sqrt{\frac{3}{2}}$

$\frac{a}{r} = \frac{\sqrt3 - \sqrt2}{\sqrt2}$

so we will have

$r = \frac{a\sqrt2}{\sqrt3 - \sqrt2}$

so the x coordinate of this position is given as

$x = a + \frac{a\sqrt2}{\sqrt3 - \sqrt2}$

Which two components must a vector quantity

Lemur [1.5K]

Answer:

d. Direction and magnitude

Explanation:

The two components of a vector are its magnitude and direction.

Magnitude is the quantity of the substance

Direction is the path.

Other quantities are called scalar quantities.
Scalar quantities have only magnitude but no direction.

Examples of vector quantities are velocity, displacement, acceleration.

The gravitational force between two objects is 1600 N. What will be the gravitational force between the objects if the distance

Luden [163]

The gravitational force is inversely proportional to squared distance.
This means when the distance between the objects is increased, the gravitational force reduces.

1600 = k/d². where k is constant.
k=1600d²

When d is doubled, the gravitational force, F,

F = 1600d²/(2d)²
F = 400 N

We will determine the amount of electric energy stored in a capacitor by discharging it through a light bulb. Light bulbs are ra

choli [55]

Answer:

C. the product of the power rating of the light bulb and the time that it remains lit.

Explanation:

The power rating of the light is bulb is defined as the energy supplied to the light bulb divided by the time the bulb is lit up. Therefore,

$P = \frac{E}{t}\\\\E = Pt$

where,

E = Energy Supplied to the bulb = Energy stored in capacitor = ?

P = Power rating of the bulb

t = time the bulb is lit up

Hence, the correct option is:

<u>C. the product of the power rating of the light bulb and the time that it remains lit.</u>
