So I already know A is where the suns energy is produced.

Here are the options for the rest :


• region of the sun that is visible from earth

• appears as a red ring around the sun right before and after the peak of a total solar eclipse

• region that energy travels to through radiation ( movement of high energy particles )

• appears as a white ring or crown around the sun at the time of total solar eclipse

so please tell me the answer for each ( A, B, C, D ) thank you !

Answer:

It is a constant when the light is traveling in a vacuum.

Answer:

medium

Examples:

A medium is a thing that the sound wave would travel through, like sound waves traveling through air. A mechanical wave cannot travel without a medium, like if the wave were trying to travel through a vacuum.

Answer:

Explanation:

Step one:

given data

initial velocity u= 40m/s

time taken t=3seconds

final velocity v=?

Step two:

applying the first equation of motion

v=u-gt---  (the -ve sign implies that the arrow is against gravity)

assume g=9.81m/s^2

v=40-9.81*3

v=40-29.43

v=10.57m/s

Step three:

how high the target is located

applying

s=ut-1/2gt^2

s=40*3-1/2(9.81)*3^2

s=120-88.29/2

s=120-44.145

s=75.86m

2

The parents are bred together, and their offspring will be different sizes.

3

The biggest offspring will be selected and bred together.

4

This cycle continues until the dogs have been selectively bred to be bigger than the current world record size.

5

Selective breeders need to ensure that they are not also selecting for disadvantageous traits, like genetic limb defects.

Answer:

Geological and atmospheric changes happening over a long time scale can cause short extinctions.

Explanation:

Answer:

Explanation:

Well, lets say you park your car on the top of a hill, gravitational energy prevents it from the car falling back. Or a snow pack, aka before a potential avalanche. Though gravity cannot keep it safe forever, gravitational energy keeps it from crashing asap. In this case, it gives you time to escape. Altogether, gravitational force keeps the earth in it's atmosphere.

Answer:

It would take the cyclist 2 hours to cycle to school.

Explanation:

5km/hr for 2 hours would be 10km.

Answer:

distance and time

Explanation: the farther you go and how much time it will take you

Answer:

(a) Cyclist A travels faster.

(b) The time taken by cyclists A and B is 10 minutes and 8.58 minutes respectively.

Explanation:

Given that the speed of cyclist A= 24 km/h

As 1 km = 1000 m and 1 hour= 3600 seconds.

So, [tex]24 \frac {km}{h}=24\times \frac{1000 m}{3600 s}=\frac{20}{3}\frac {m}{s}=6.67 m/s[/tex]

and the speed of cyclist B = 6.8 m/s.

The length of the road = 4 km=4000 m.

(a) Speed of cyclist A is 6.67 m/s which is more than the 6.8 m/s.

Hence, cyclist A travels faster.

(b) If d be the distance to be traveled and V be the speed, than the time, t, required is,

[tex]t=\frac{d}{V}\cdots(i)[/tex]

For cyclist A:

As A is located at the beginning of the road, he has to cover full length of the road.

So, the distance to be covered by cyclist A =4 km.

Hence, from equation (i), the time taken by cyclist A is

[tex]t=\frac{4}{24}=\frac{1}{6}[/tex] hour

[tex]=\frac{1}{6}\times {60}=10[/tex] minutes. [ as 1 hour = 60 minumes]

So, time taken by cyclist A is 10 minutes.

For cyclist B:

As B is located 500 meters later from the beginning of the road, he has to cover the remaining length of the road.

So, the distance to be covered by cyclist B =4000 m-500 m= 3500 m.

Hence, from equation (i), the time taken by cyclist B is

[tex]t=\frac{3500}{6.8}=514.71[/tex] seconds

As 60 seconds= 1 minute.

So, t= 514.71/60 minutes = 8.58 minutes.

[tex]=\frac{1}{6}\times {60}=10[/tex] minutes. [ as 1 hour = 60 minumes]

So, the time taken by cyclist B is 8.58 minutes.

Answer:

5m/s is the answer s=d/t 25/5=5m/s

Answer:

5m/s

Explanation:

The formula for speed is s=distance/time. The distance traveled was 25 meters. The time it took to travel that distance was 5 seconds. Therefore, s= 25m/5s to give an answer of 5 m/s

Answer:

I believe gravity is acting on it

Answer:

Explanation:

100c+13600kg÷m2

The density of mercury is 13600 kg / m³ at 0 °C. Its density at a temperature of 100 °C is 0.735 × 10⁻⁴  kg / m³.

The mass of a material substance per unit volume is its density. The formula for density is [tex]d = M/V[/tex] Where d represents density, M is mass, and V is volume. Density is commonly measured in grams per cubic centimeter.

As an example, the density of Earth is 5.51 grams per cubic centimeter, but the density of water is 1 gram per cubic centimeter.

Given:

The density of mercury, d = 13600 kg / m³,

The temperature difference. ΔT = 100 - 0 = 100 °C,

Calculate the change in volume if the mass is 13.6 kg and the coefficient of cubical expansion is 1.82×10⁻⁴ °C⁻¹ by the formula given below,

ΔV = V α ΔT

ΔV = (13.6 ÷ 13600) × 1.82 × 10⁻⁴

ΔV = 0.00182 × 10⁻⁴ m³

New volume V₁​ = V + ΔV = 13.6 ÷ 13600 + 0.00182 × 10⁻⁴

New density d₁ = V₁ / 13.6  =  10.00182 × 10⁻⁴ / 13.6 = 0.735 × 10⁻⁴  kg / m³

Therefore, the density of mercury is 13600 kg / m³ at 0 °C. Its density at a temperature of 100 °C is 0.735 × 10⁻⁴  kg / m³.

Initial speed of the coin (u)= 0 (As the coin is released from rest)

Acceleration due to gravity (a) = g = 9.81 m/s²

Time of fall (t) = 1.5 s

From equation of motion we have:

[tex] \boxed{ \bf{v = u + at}}[/tex]

By substituting values in the equation, we get:

[tex] \longrightarrow [/tex] v = 0 + 9.81 × 1.5

[tex] \longrightarrow [/tex] v = 14.715 m/s

[tex] \therefore [/tex] Speed of the coin as it hits the ground/Final speed of the coin = 14.715 m/s

The speed of the coin as it hits the ground is 14.715 m/s.

We can solve the problem above using the equation of acceleration under gravity.

⇒ Equation:

v = u+gt................... Equation 1

⇒ Where:

From the question,

⇒ Given:

Substitute these values into equation 1

Note the speed has a negative sign because it acts in the same direction as the acceleration due to gravity

Hence, the speed of the coin as it hits the ground is 14.715 m/s.

weather is everyday things

weather could be a hurricane

weather could be a tornado

climate is more long term over time

example the climate in Antarctica is cold because it happens over long periods overtime

Answer:

42.05 m/s

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 0 m/s

Height (h) = 239 m

Acceleration due to gravity (g) = 3.7 m/s²

Final velocity (v) =?

The velocity with which the camera hits the ground can be obtained as follow:

v² = u² + 2gh

v² = 0² + 2 × 3.7 × 239

v² = 0 + 1768.6

v² = 1768.6

Take the square root of both side

v = √(1768.6)

v = 42.05 m/s

Therefore, the velocity with which the camera hits the ground is 42.05 m/s
