Answer:

Option (4)

Explanation:

When the earth's tilt is oriented towards the sun, then this condition depicts that it is summer in the northern hemisphere, whereas in the southern hemisphere it is winter. So the seasons that occur at different times in both the hemisphere are opposite to one another.

In the southern hemisphere, the spring season starts approximately from the starting of September and ends in the month of November.

So from the given image, it can be concluded that point D is the position in which the Southern hemisphere experiences the spring season.

Thus, the correct answer is option (4).

a light wave travels at 3.0 x 10^8 m/s. if the wavelength of a red wave is 700 x 10^-9m, what is the frequency?

asambeis [7]

Frequency = (speed) divided by (wavelength)

   = (3 x 10⁸ m/s) / (700 x 10⁻⁹ m)

   = (3 / 700) x 10¹⁷ ( per sec )

   = 4.286 x 10¹⁴ per sec = 4.286 x 10¹⁴ Hz.

   = 42,860 GHz .

A group of particles is traveling in a magnetic field of unknown magnitude and direction. You observe that a proton moving at 1.

Brilliant_brown [7]

Answer:

Explanation:

velocity of proton v = 1.5 x 10³ i m /s

charge on proton e = 1.6 x 10⁻¹⁹ C

Let the magnetic field be B = Bx i + Bz k

force on charged particle ( proton )

F = e ( v x B )

2.06 x10⁻¹⁶ j = 1.6 x 10⁻¹⁹ [ 1.5 x 10³ i x ( Bx i + Bz k) ]

2.06 x10⁻¹⁶ j = - 1.6 x 10⁻¹⁹ x 1.5 x 10³ Bz j) ]

2.06 x10⁻¹⁶ = - 1.6 x 10⁻¹⁹ x 1.5 x 10³ Bz

Bz = - .8583

force on charged particle ( electron )

F = e ( v x B )

8.40 x10⁻¹⁶ j = -1.6 x 10⁻¹⁹ [ - 4.4 x 10³ k x ( Bx i + Bz k) ]

8.4 x10⁻¹⁶ j = 1.6 x 10⁻¹⁹ x 4.4 x 10³ Bx j ]

- 8.4 x10⁻¹⁶ = 1.6 x 10⁻¹⁹ x 4.4 x 10³ Bx

Bx = - 1.19

Magnetic field = - 1.19 i - .8583 k

magnitude = √ (1.19² + .8583²)

= 1.467 T

If it is making angle θ with x - axis in x -z plane

Tanθ = (.8583 / 1.19 )

36⁰ .

C )

v = - 3.7 x 10³j m /s

e = - 1.6 x 10⁻¹⁶ C

Force = F = e ( v x B )

= -1.6 x 10⁻¹⁹ [ -3.7 x 10³ j x ( Bx i + Bz k) ]

= - 1.6 x 10⁻¹⁹ x 3.7 x 10³ Bx k -1.6 x 10⁻¹⁹ x 3.7 x 10³Bzi ]

= 5.08 i - 7.04 k

Tanθ = 54 ° .

What is the acceleration of a car that moves at a steady velocity of 100 km/h for 100 seconds? Explain your answer.

RUDIKE [14]

Answer:

a = 0 m/s²

Explanation:

given,

car moving at steady velocity = 100 Km/h

1 km/h = 0.278 m/s

100 Km/h = 27.8 m/s

time of acceleration = 100 s

acceleration is equal to change in velocity per unit time.

$a=\dfrac{dv}{dt}$

change in velocity of the car is 27.8 - 27.8 = 0

$a=\dfrac{0}{100}$

a = 0 m/s²

If the car is moving with steady velocity then acceleration of the car is zero.

Hence, the acceleration of the car is equal to a = 0 m/s²

Road rage is an aggressive driving incident where the driver has:

WARRIOR [948]

I would say that it would be A.) Been insulted. This is because you are angered by someone else. It does not necessarily mean that something has de-escelated, you've lost control of your car, or you've nothing to lose. Hopefully that helps. :)

Suppose that a worker in Freedonia can produce either 6 units of corn or 2 units of wheat per year, and a worker in Sylvania can

Salsk061 [2.6K]

Answer:

a 30 units of corn and 30 units of wheat.

Explanation:

Initially freedonia has 5 workers producing 30 units of of corn (6 units per worker) and another 5 workers producing 10 units of wheat (2 units per worker)

With the trade agreed between the two countries Freedonia can have all of it's 10 workers producing corn, thereby producing 60 units of corn

30 of these are traded for 30 units of wheat therefore allowing the country to consume 30 units of each product.
