A scientist noticed that a dark-colored peppered moth is more visible on a light-colored background than a light-colored peppere

d moth. He wonders, “Does this difference in visibility affect the survival rate of dark moths?” Which part of the scientific method does he need to carry out next?

Answer: Form a hypothesis

A scientific way to investigate a problem involves mainly five steps.

→A question or problem must be formulated in the first step.

→After gathering the background information, A hypothesis must be made.

→Third step would be to design an experiment.

→Fourth step would include collection and recording of data.

→Fifth step would include the conclusions drawn from the experiment and communication of hypothesis and its results.

When  the scientist notices that a dark colored peppered moth over light colored background, he formulates a question: whether the difference in visibility affects the survival rate of dark moths or not? Therefore, next step in the scientific method would be to gather more information on the subject and formulate a hypothesis.

Which variety of moth, C or Y, is more likely to be killed by insect eating birds?
Svetlanka [38]
Moth X is more likely to be eaten by insect killing birds first. This is because Moth Y blends in with the tree trunk more and is hidden from birds. Its wings camouflage with the tree trunk, hiding it from sight.

Newton's laws of motion are true on earth and space.
frez [133]

Answer:

False

Explanation:

It is a common misunderstanding that objects in space have no weight. If that were true, they would just float away from the Earth, the Sun and the other planets. Objects in low Earth orbit experience about 90% of the weight that they feel on the surface of the Earth.

How does air resistance affect how fast a feather falls?
Korvikt [17]

Answer: Ain't its because how light the feather is ? It's not as heavy.

Explanation: With air resistance, acceleration throughout a fall gets less than gravity (g) because air resistance affects the movement of the falling object by slowing it down. ... Usually, resistance is not very high at low speed or for small or sharp objects (Google Source if needed to prove yours answer)

A point charge A of charge +4micro coloumb and another B of -1 micro coloumb are placed at a distance in air 1m apart then the d
andrew11 [14]

Answer:

Explanation:

Given that,

A point charge is placed between two charges

Q1 = 4 μC

Q2 = -1 μC

Distance between the two charges is 1m

We want to find the point when the electric field will be zero.

Electric field can be calculated using

E = kQ/r²

Let the point charge be at a distance x from the first charge Q1, then, it will be at 1 -x from the second charge.

Then, the magnitude of the electric at point x is zero.

E = kQ1 / r² + kQ2 / r²

0 = kQ1 / x²  - kQ2 / (1-x)²

kQ1 / x² = kQ2 / (1-x)²

Divide through by k

Q1 / x² = Q2 / (1-x)²

4μ / x² = 1μ / (1 - x)²

Divide through by μ

4 / x² = 1 / (1-x)²

Cross multiply

4(1-x)² = x²

4(1-2x+x²) = x²

4 - 8x + 4x² = x²

4x² - 8x + 4 - x² = 0

3x² - 8x + 4 = 0

Check attachment for solution of quadratic equation

We found that,

x = 2m or x = ⅔m

So, the electric field will be zero if placed ⅔m from point charge A, OR ⅓m from point charge B.
