Answer:

Explanation:

The thunderstorm lightning is generated by the collision of the charged clouds in the earth's atmosphere. It has a tendency to flow to the earth because it acts as a reservoir for the electrical charges.

In the following condition a person is prone to be struck by lightning:

When a person is standing below tall buildings having no provision of dissipating the electrical lightening because it provides a low resistance path for the flow of charge to the earth.

When a person is standing below a tall tree it also provides low resistance and high conductivity path for the charges to flow to the reservoir earth.

Select the correct location on the image.<br> Identify the magnetic north pole of Earth’s magnet.

OverLord2011 [107]

The magnetic north pole of the earth's magnet is in the geographic south pole.

There are two magnetic and geographic poles each, north and south
The two geographic poles are the locations where the earth's axis of rotation passes through which is imaginary
The magnetic north and south poles are not the same as the geographic north and south poles
In a compass, the needle points to the magnetic north pole
By convention, the magnetic north pole corresponds to the geographic south pole
The magnetic south pole corresponds to the geographic north pole
The magnetic field lines of a magnet start from the magnetic north pole and end at the magnetic south pole

The magnetic north pole of the earth's magnet is the geographic south pole.

On a spacecraft, two engines are turned on for 789 s at a moment when the velocity of the craft has x and y components of v0x =

ddd [48]

Answer:

Explanation:

Given

time for which spacecraft turned on is 789 s

$v_{0x}=5410 m/s$

$v_{0y}=8100 m/s$

$x=2.78\times 10^6 m$

$y=4.73\times 10^6 m$

we know $s=ut+\frac{at^2}{2}$

$2.78\times 10^6=5410\times 789+\frac{a_x(789)^2}{2}$

$2.78=4.268+a_x\times 0.622$

$a_x=-2.392 m/s^2$

For y component

$s=ut+\frac{at^2}{2}$

$4.73\times 10^6=8100\times 789+\frac{a_y(789)^2}{2}$

$4.73=6.39+a_y\times 0.622$

$a_y=-2.66 m/s^2$

14. The United States Tobacco Settlement between the major tobacco companies and 46 states caused the price of cigarettes to jum

AysviL [449]

Answer:

B. The elasticity of demand is -0.126

Explanation:

% Change in Quality demand = -2.65% (negative because of drop)

% Change in price = 21%

Elasticity of demand is given by

$\text{Elasticity of demand}=\dfrac{\text{\% Change in Quality demand}}{\text{\% Change in price}}\\\Rightarrow \text{Elasticity of demand}=\dfrac{-2.65}{21}\\\Rightarrow \text{Elasticity of demand}=-0.12619$

The Elasticity of demand is -0.12619

WhAT is the change IN THE entropy of 2.0kg of h2o molecules when transform at a constant pressure of 1 atm from water at 100 deg

Fynjy0 [20]

Answer:

The entropy change is 45.2 kJ/K.

Explanation:

mass of water at 100 C = 2 kg

Latent heat of vaporization, L = 2260 kJ/kg

Heat is

H = m L

H = 2 x 2260 = 4520 kJ

Entropy is given by

S = H/T = 4520/100 = 45.2 kJ/K

An uncharged capacitor and a resistor are connected in series to a source of emf. If E = 9.00 V, C=20.0μF , and R = 100ω , find

Levart [38]

Based on the values of E, C, and R, the maximum charge on the capacitor can be found to be 1.80 x 10⁻⁴ C.

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

The maximum charge on the capacitor can be found as:

= C x ( 10⁻⁶ / 1 μF) x E

Solving gives:

= 20.0 x ( 10⁻⁶ / 1 μF) x 9.00

= 1.80 x 10⁻⁴ C

In conclusion, the maximum charge is 1.80 x 10⁻⁴ C
