Answer:

Asking a question

Research existing sources

Define an hypothesis

Design and conduct a study

Draw conclusion

Report result.

Explanation:

Scientific study simply means establishing the existence or proving the veracity of an hypothesis, hence making it a fact. A scientific study follows an orders set of procedure;

Asking a question is the first step as this is what prompts the research, question usually stems after making an observation.

The a observation made and question asked will lead to making research on the observed phenomenon, this is to check if such question has been asked in the past and maybe any scientific study as been carried out in the past.

To make research further, an hypothesis is defined in a bid to find more evidence to support one's observation through experiment.

Study design and implementation is next as the type of study to be embarked upon will determine which type of design preparation and study pattern to deploy.

Conclusion a d report of observations made are the last part of a scientific study which is key as all outcomes of the study should be adequately detailed in an understandable format while also ensuring reproducibility.

Sarah and Devon are involved in an egg catching contest. They stand a fixed distance apart and toss a raw egg back and forth to
Georgia [21]

Answer:

The correct answer is - B. Increase the time it takes to stop the egg once it hits his hand.

Explanation:

In order to catch the egg the force and time makes an impulse to the egg to change its momentum and bring it to rest. In order to change the momentum, one needs to decrease the force exerted onto the egg and increase the time it takes to make it rest.

Less force can be given to the egg by increasing the time to bring it to rest stop the egg once it hits his hand. Other than this it should be caught to the sides.

WORTH 10 POINTS! I WILL GIVE BRAINLIEST!
Sav [38]

Answer:

The Sun’s magnetic field, solar winds and the Earth's magnetic tail are responsible for making the aurora lights in the north and south poles look different, say international scientists. Researching the interactions of these phenomena have debunked previous theories around why the lights can have different shapes and can occur in different locations. This research also helps scientists to better understand the interactions between the sun and earth, which could help with predicting space weather.

Motor oil, with a viscosity of 0.25 N ∙ s/m2, is flowing through a tube that has a radius of 3.0 mm and is 1.0 m long. The drop
Alex73 [517]

Answer:

The average speed of the oil is 1 m/s.

Explanation:

Given that,

Viscosity \eta= 0.25 N-s/m^2

Radius r = 3.0 mm

Length = 1.0 m

Pressure = 200 kPa

We need to calculate the average speed of the oil

Using formula of pressure

\Delta P=\dfrac{8\pi\eta\rho v}{A}

v=\dfrac{A\times\Delta P}{8\pi\eta\rho}

Where, A = area

\rho = density of oil

\eta = viscosity

Put the value into the formula

v=\dfrac{\pi\times(3.0\times10^{-3})^2\times200\times10^{3}}{8\pi\times0.25\times0.9}

v=1\ m/s

Hence, The average speed of the oil is 1 m/s.

A ball at the top of a hill is an example of ______ and a ball rolling down the hill is an example of ______.

Potential energy , Kinetic energy

<h3 /><h3>What is kinetic energy and potential energy?</h3>

Kinetic energy is a form of energy that posses by an object due to its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy.

Potential energy is the energy held by an object due to its position relative to other objects, stresses within itself, its electric charge, or other factors.

According to given condition,

At first,

When a ball is at the top of a hill , it posses a potential energy because the ball is at some height from the surface  where  the energy held by ball is due to its position.

That is why,  a ball at the top of a hill is an example of Potential energy.

Secondly,

When a ball is rolling down the hill , it posses kinetic energy because the ball have some energy that posses by an object due to its motion.

That is why, a ball rolling down the hill is an example of  Kinetic energy.
