Answers

Explanation:

A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.

Formula: Fg= G*M,*M,/d? G= 6.67 * 10-11 N*M°/Kg?
The distance between Earth and its moon is 3.84 x 10 meters. Earth's mass is
m = 5.98 x 1024 kilograms and the mass of the moon is 7.36 x 1022 kilograms.
What is the force between Earth and the moon?

Answers

Answer:

The force between Earth and the moon is 1.99x10²⁶ N.

Explanation:

The force between Earth and the moon can be found using the Gravitational Force equation:

[tex] F_{g} = \frac{Gm_{E}m_{m}}{d^{2}} [/tex]

Where:

d: is the distance between Earth and the moon = 3.84x10⁵ m

G: is the gravitational constant = 6.67x10⁻¹¹ Nm²/kg²

[tex]m_{E}[/tex]: is the Earth's mass = 5.98x10²⁴ kg

[tex]m_{m}[/tex]: is the moon's mass = 7.36x10²² kg

Hence, the force is:

[tex] F_{g} = \frac{Gm_{E}m_{m}}{d^{2}} = \frac{6.67 \cdot 10^{-11} Nm^{2}/kg^{2}*5.98\cdot 10^{24} kg*7.36\cdot 10^{22} kg}{(3.84\cdot 10^{5} m)^{2}} = 1.99 \cdot 10^{26} N [/tex]

Therefore, the force between Earth and the moon is 1.99x10²⁶ N.

It is winter. You are very cold. Your body systems cooperate and respond to the cold in three ways in an effort to keep you warm. Choose the answer that is NOT correct.


Your nervous system slows down and the impulses that move your muscles also slows, helping to retain heat.


The body will try to generate heat itself by allowing muscles and organs to shake within the body: this is known as shivering.


Blood flow is diverted from muscle tissue to fat. The rapid decomposition fat (adipose) tissue generates heat energy that helps to raise the body's temperature.


Cold causes blood vessels to constrict and blood flow resistance to increase. Reducing blood flow to the skin and the extremities reduces heat transferred to the environment.

Answers

Answer:

The third option

Explanation:

A and B are true because this can be noticed by just any human. So then you are left with C and D. With these two, D makes more sense. Since when someone gets cold, their blood flow is reduced starting in areas like your fingers, hands, toes and feet. These areas get the coldest since they are the smallest and furthest away from the rest of your body. Also since these areas touch surfaces more than other areas, they will have less heat to transfer.

Blood flow is diverted from muscle tissue to fat. The rapid decomposition fat (adipose) tissue generates heat energy that helps to raise the body's temperature. - This answer is NOT correct.

What is nervous system?

nervous system is a network of organized cells with the specific purpose of carrying electrochemical inputs from sensory receptors to the location where a response takes place.

Every living thing has the capacity to recognize changes in both its own surroundings and outside it. Changes in the internal environment include those in the position of the head and limbs as well as those in the internal organs, whereas changes in the exterior environment include those in light, temperature, sound, motion, and odor

.

Two different kinds of systems, physiologic and behavioral, control body temperature.

distance of 275 m after leaving the 100. m high cliff. If the cannonball was launched from horizontal, at what velocity

did it leave the cannon? At what velocity (resultant speed + angle) did it hit the sea? (Clearly, they missed the ship!)

Show work

Answers

Answer:

Explanation:

The cannonball goes a horizontal  distance of 275 m . It travels a vertical distance of 100 m

Time taken to cover vertical distance =  t ,

Initial velocity u = 0

distance s = 100 m

acceleration a = 9.8 m /s²

s = ut + 1/2 g t²

100 = .5 x 9.8 x t²

t = 4.51 s

During this time it travels horizontally also uniformly so

horizontal velocity Vx = horizontal displacement / time

= 275 / 4.51 = 60.97 m /s

Vertical velocity Vy

Vy = u + gt

= 0 + 9.8 x 4.51

= 44.2 m /s

Resultant velocity

V = √ ( 44.2² + 60.97² )

= √ ( 1953.64 + 3717.34 )

= 75.3 m /s

Angle with horizontal Ф

TanФ = Vy / Vx

= 44.2 / 60.97

= .725

Ф = 36⁰ .

Vehicle driving round a curve

Consider a ball tossed from the ground into the air at 25 m/s. At a later time, the ball is measured to be moving downward at 11 m/s. a) Find how high the ball is off of the ground at the later time. b) Find the time interval between these two events. c) Sketch graphs of position, velocity, and acceleration versus time for the ball.

Answers

Answer:

The answer is below

Explanation:

a) According to Newton's law of motion, the distance travelled by a body going upward can be calculated using the formula:

v² = u² - 2gh

where v is the final velocity, u is the initial velocity, g is the acceleration due to gravity and h is the height of the ball.

g = 10 m/s², u = 25 m/s, v = 11 m/s

Substituting:

11² = 25² - 2(10)h

20h = 25² - 11²

20h = 504

h = 25.2 m

b) The time (t) can be gotten using:

v = u - gt

Substituting

11 = 25 - 10t

10t = 25 - 11

10t = 14

t = 1.4 s

c) the graph were plotted using an online graphing tool

A train travels between two stations that are 63 km apart at an average speed of 35 m/s. Time taken by train after leaving the first station and arrive at the second station  1.8 sec.

What is speed?

The speed of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.

time = Distance / speed

= 63/35.

= 1.8 sec

A wave has a wavelength of 3.3 m and a speed of 5.6 m/s. What is the frequency of this wave

Answers

Answer: λ (wavelength) = 3.3 m →  ΔS = 3.3 m

T (period) → ΔT = ?

f (frequency) = ?

If:

Now: (if, ΔT = T), Using the formula of the period of a wave, find the frequency:

Explanation: Your Welcome u.u

The frequency of this wave is approximately 1.697 Hz.

To find the frequency of a wave, we can use the formula:

frequency (f) = speed (v) / wavelength (λ)

Given:

Wavelength (λ) = 3.3 m

Speed (v) = 5.6 m/s

Substituting these values into the formula, we can calculate the frequency:

f = v / λ

f = 5.6 m/s / 3.3 m

f ≈ 1.697 Hz

Therefore, the frequency of this wave is approximately 1.697 Hz.
