how is light reflected from a prism​

Answers

Answer:

White light entering a prism is bent, or refracted, and the light separates into its constituent wavelengths. Each wavelength of light has a different colour and bends at a different angle. The colours of white light always emerge through a prism in the same order—red, orange, yellow, green, blue, indigo, and violet.

an experiment involving the scientific method begins with a/an:

Answers

Answer:

Step 1. Make observations.

Step 2. Form a hypothesis.

Step 3. Make a prediction.

Step 4. Perform an experiment.

Step 5. Analyze the results of the experiment.

Step 6. Draw a conclusion.

Step 7. Report your results.

Explanation:

The first step in the Scientific Method is to make objective observations. These observations are based on specific events that have already happened and can be verified by others as true or false. Step 2. Form a hypothesis.

Our observations tell us about the past or the present. As scientists, we want to be able to predict future events. We must therefore use our ability to reason.

Scientists use their knowledge of past events to develop a general principle or explanation to help predict future events. The general principle is called a hypothesis. The type of reasoning involved is called inductive reasoning (deriving a generalization from specific details).

A hypothesis should have the following characteristics:

• It should be a general principle that holds across space and time

• It should be a tentative idea

• It should agree with available observations

• It should be kept as simple as possible.

• It should be testable and potentially falsifiable. In other words, there should be a

way to show the hypothesis is false; a way to disprove the hypothesis.

Some mammals have two hind limbs would be a useless hypothesis. There is no observation that would not fit this hypothesis!

All mammals have two hind limbs is a good hypothesis. We would look throughout the world at mammals. When we find whales, which have no hind limbs, we would have shown our hypothesis to be false; we have falsified the hypothesis.

When a hypothesis involves a cause-and-effect relationship, we state our hypothesis to indicate there is no effect. A hypothesis, which asserts no effect, is called a null hypothesis. For instance, the drug Celebra does not help relieve rheumatoid arthritis.

Who exerts more pressure? a) A girl of 50 kg, wearing heels with an area of 1 cm2. b) An elephant of 4000 kg with foot area of 250 cm2.

Answers

Answer:

The girl exerts more pressure.

Explanation:

Pressure can be defined as the force exerted normally or perpendicularly per unit area.

i.e P = F/A

Girls

Area of the heel = 1cm² = 10^(-4) m²

Force = mg = 50 × 10 = 500N

Pressure =

[tex] \frac{500}{10 ^{ - 4} } [/tex]

[tex] = 5 \times {10}^{6}[/tex]

Elephant

Area = 250cm² = 2.5 x 10^(-2)b m²

Force = mg = 40000N

Pressure =

[tex] \frac{40000}{2.5 \times {10}^{ - 2} } [/tex]

[tex] = 1.6 \times {10}^{6} [/tex]

Answers

Answer:

the answer is

Explanation:

constant acceleration

because when the object's velocity is changing then the object is accelerating or decelerating

as acceleration describe changing of velocity so the answer is constant acceleration

Acceleration is defined as the rate of change of velocity.

Acceleration = (Change in velocity) / time taken

Acceleration = (Final velocity - initial velocity) / time

As the object velocity changes by the same amount in each second, it means the acceleration is constant.

Nikki has a momentum of 45 Kilogram meters per second and a mass of 30 Kilograms. What is her velocity?

Answers

Answer:

45/30

Explanation:

bbsksksbsnbksbsksbs

Nikki has a momentum of 45 Kilogram meters per second and a mass of 30 Kilograms. then her velocity would be 1.5 meters per second

What is momentum?

It can be defined as the product of the mass and the speed of the particle, it represents the combined effect of mass and the speed of any particle, and the momentum of any particle is expressed in Kg m/s unit.

Mathematically the formula of the momentum is

P = mv

where P is the momentum of the particle

m is the mass of the particle

v is the velocity by which the particle is moving

As given in the problem Nikki has a momentum of 45 Kilogram meters per second and a mass of 30 Kilograms

P = 45 Kilogram meters per second

m = 30 Kilograms

By substituting the values of the momentum and the mass in the formula of the momentum

P = mv

45 = 30 ×v

v = 45/30 meters per seconds

v = 1.5 meters per seconds

Thus, Nikki weighs 30 kilograms and moves at a 45 kilogram per the second momentum. subsequently, her velocity would be 1.5 meters per second.

11 An unstretched spring is 12,0 cm long. A load of 5.0N stretches it to 15.0cm. How long will it be under a load
of 15N? (Assume that the spring obeys Hooke's law.)

Answers

Answer: Approximately 22 cm

=========================================================

Explanation:

The unstretched spring is 12.0 cm long. When adding a load of 5.0 N, it stretches to 15.0 cm. This is a displacement of 15.0 - 12.0 = 3.0 cm, which is the amount the spring is stretched.

Convert this displacement to meters (so that it fits with the meters unit buried in Newtons).

3.0 cm = (3.0)/100 = 0.03 m

Apply Hooke's Law to find the spring constant k

F = -kx

5.0 = -k*(0.03)

k = -(5.0)/(0.03)

k = -166.667 approximately

Now we must find the displacement x when F = 15 newtons

F = -kx

-kx = F

x = F/(-k)

x = -F/k

x = -15/(-166.667)

x = 0.089 approximately

x = 0.1

The displacement to one decimal place is about 0.1 meters, which converts to 100*0.1 = 10 cm

So the spring will be stretched to about 12cm+10cm = 22 cm

ASAP If the initial pressure of a gas is 100 kPa, initial volume is 1.0 L, and final pressure is 25 kPa, what is the final volume?

When no one answers your question...

Answers

The final volume is 4.0 liters.

We can calculate the final volume with Boyle's law:

[tex] P_{i}V_{i} = P_{f}V_{f} [/tex]  (1)

Where:

[tex] P_{i}[/tex]: is the initial pressure = 100 kPa

[tex] V_{i}[/tex]: is the initial volume = 1.0 L

[tex]P_{f}[/tex]: is the final pressure = 25 kPa

[tex]V_{f}[/tex]: is the final volume =?

Hence, the final volume is:

[tex] V_{f} = \frac{P_{i}V_{i}}{P_{f}} = \frac{100 kPa*1.0 L}{25 kPa} = 4.0 L [/tex]

Therefore, the final volume is 4.0 liters.

7. A train is traveling with an initial velocity of 20.1 m/sec. If the brakes can apply a maximum
acceleration of -0.0500 m/sec”, how long will it take the train to stop?

Answers

The time that takes for the train that is traveling with an initial velocity of 20.1 m/s to stop is 402 seconds.    

The time that will take for the train to stop can be calculated with the following kinematic equation:

[tex] v_{f} = v_{i} + at [/tex]   (1)

Where:

[tex] v_{f}[/tex]: is the final velocity = 0 (when it stops)

[tex] v_{i}[/tex]: is the intial velocity = 20.1 m/s

a: is the acceleration = -0.0500 m/s²

t: is the time =?

By solving equation (1) for t, we have:

[tex] t = \frac{v_{f} - v_{i}}{a} = \frac{0 - 20.1 m/s}{-0.0500 m/s^{2}} = 402 s [/tex]

Therefore, it will take 402 seconds for the train to stop.
