Answer:

1a) True  1b) False

Explanation:

The definition of a car's velocity is the change of displacement between time, from here we can see that this is a vector, this means that it has magnitude and direction.

The definition of speed is the change of distance between the unit of time, as we see this magnitude is a scalar since distance is a scalar.

1 a) the car has the same speed, True since the magnitude is a scalar

1 b) the cars have the same speed. False since the magnitude is a vector, even if it has the same module it has different direction

An incident electromagnetic wave is polarized and its E vector has a maximum value of 6 Volts/m. It is incident on a polarizer w
adell [148]

To solve this problem it is necessary to apply the equations related to the law of Maus.

By the law of Maus we know that

I = I_0 cos^2 \theta

Where,

I_0 = Intesity of incident light

I = Intensity of polarized light

With our values we have that

I_0 = 6V/m

\theta = 45\°

Then

I = 6*cos^2(45)

I = 3V/m

Therefore the maximum value of the transmitted E vector is 3V/m

Does the elf owl's small size allow it to live in cacti
kaheart [24]
Habitat
-In the Sonoran Desert region, elf owls are found mainly in riparian habitats (places where there is water), or in areas where saguaro cactus are plentiful.

Range
-Elf Owls are found from the southwest USA to Central Mexico and Baja California. Northern populations winter in Central Mexico and on the Pacific slope north to Sinaloa, Mexico.

Wild Status
-The most important threat to the elf owl is habitat loss both of its riparian forest habitat and desert-scrub habitats. In Arizona, the elf owl is not uncommon, but it's numbers are decreasing in California and Texas.

-So I mean like ya it's possible that they could live in cacti. Sorry that I couldn't give you a straight answer.

The temperature at which the velocity of sound in air is twice its velocity at 15°C
Elena L [17]

With the use of below formula, at 879 °C,  velocity will be double the velocity at 15 °C.

<h3>What is the relationship between Velocity and sound ?</h3>

The velocity of sound waves in air is proportional to the square root of Thermodynamic temperature. That is, V = K\sqrt{T}

Given that the temperature at which the velocity of sound in air is twice its velocity at 15°C, Let us make use of the formula;

(v2/v1) = √(T2 / T1)

Where

  • v2 = final velocity
  • v1 = initial velocity
  • T2 = final absolute temperature
  • T1 = initial temperature.

Recall that absolute temperature = °C + 273.

If v2 = 2 × v1 and temperature in degree Celsius = 15°C, then,

Temperature in Kelvin K = 15 + 273 = 288

Substitute all the parameters into the formula

(2 × v1)/v1 = √(T2/288)

2 = √ (T2 /288)

Square both sides

4 = (T2/288)

T2 = 4 × 288

T2 = 1152K

Temperature in degrees Celsius = 1152 - 273 = 879 °C.

Therefore, at 879 °C,  velocity will be double the velocity at 15 °C.
