Answer:

b. migration

A migration can be defined as the changes that occur in the behavior, structure, physiology of the organism so as to allow it to survive in unfavorable environmental conditions. Behavioral adaptation can be defined as the changes that occur in an organism's behavior which affects it's actions and helps it to survive like choice of mating partner, calling the mates for copulation and migration to different location all are the examples of the behavioral adaptations

Explanation: Behavioral adaptations are the things organisms do to survive. For example, bird calls and migration are behavioral adaptations. Adaptations are the result of evolution. Evolution is a change in a species over long periods of time.

Answer:

A

Explanation:

Answer:

According to Pascals law, THE PRESSURE EXERTED TO A CONFINED LIQUID IS TRANSMITTED EQUALLY AND UNDIMINISHED IN ALL DIRECTIONS THROUGHOUT THE MASS OF THE LIQUID--Blaise Pascal

so the pressure at A2 must be equal to A1

buy however the F1 will be less than F2 since:

P1=F1/A1 and P2=F2/F1

P1=P2 according to Pascal

so, F1/A1=F2/A2

with less amount of force at P1 THE force gets multiplied.

Therefore it's obvious that option A and B is wrong. I can't see option C properly.

but, you are going to have this option.

C.F1>F2

so the option with F1>F2 is correct

Answer:

True

Explanation:

The energy carried by a wave is proportional to its amplitude squared. The larger the strength of the electric and magnetic fields, the more work they can do and the greater the energy the electromagnetic wave carries. A wave's energy is proportional to its amplitude squared (E2 or B2).

The speed of the object falling freely from rest for the given distance is 50.09m/s.

Given the data in the question:

A free fall is simply any motion of a body where gravity is the sole influence.

From the third equation of motion;

[tex]v^2 = u^2 + 2gh[/tex]

Where v is final velocity, u is initial velocity, h is height and g is acceleration due to gravity ( [tex]g = 9.8m/s^2[/tex] ).

To determine the speed of the falling object, we input our values into the expression.

[tex]v^2 = u^2 + 2gh\\\\v^2 = (0)^2 + [ 2 * 9.8m/s^2 * 128m ]\\\\v^2 = 2 * 9.8m/s^2 * 128m\\\\v^2 = 2508.8m^2/s^2\\\\v = \sqrt{2508.8m^2/s^2} \\\\v = 50.09m/s[/tex]

Therefore, the speed of the object falling freely from rest for the given distance is 50.09m/s.

In order to minimize the potential energy, they repel each other (in the case of a positive and negative charge, potential energy is minimized by bringing them together, so they attract).

Explanation:

Hope it helps

Two electrons repel when they interact, because they both have similar negative electric charge.

When the two charges or the charged bodies interact each other, the force of attraction or repulsion acts between them. This force of attraction or repulsion can be find out using the coulombs law.

According to the Coulombs law, the force of attraction of repulsion between charged two bodies is directly proportional to the product of charges of them and inversely proportional to the square of distance between them. It can be given as,

[tex]F=k\dfrac{q_1q_2}{r^2}[/tex]

Here, (k) is the coulombs constant,  (q1 and q2) is the charges of two bodies and (r) is the distance between the two charges.

This force of attraction or repulsion is identified by the sign of the particular charge. According to the property of interacting charges-

As the electrons are negatively charges. Therefore, two electrons repel when they interact, because they both have similar negative electric charge.

The heat capacity depends is the heat absorbed by the calorimeter as

the temperature changes.

Response:

Mass of the vessel. m₁ = 200 gram

Temperature of the water, T₁  = 24°C

Mass of the warm water, m₂ = 112 grams

Temperature of the warm water, T₂ = 42°C

Resultant temperature of the water, T₃ = 30°C

The heat capacity of the water = 4.184 J·Kg⁻¹·K⁻¹

Let C represent the thermal capacity of the calorimeter

We have;

Change in heat, ΔH = m·c·ΔT

Therefore;

112 × 4.184 × (42 - 30) = 200 × 4.184 × (30 - 24) + C×(30 - 24)

5623.296 = 5020.8 + 6·C

6·C = 5623.296 - 5020.8 = 602.496

The squirrel has a good luck ,Car gets stopped just 1m away from the squirrel .

Explanation:

According to the Question

A squirrel runs out in front of a car moving at +20m/s ( initial speed u) . The driver slams on the brakes and begins decreasing at -8m/s² ( here the acceleration is acting in opposite directions of motion a )

When Squirrel was 26 metres ( Distance from the car initially )

Using Kinematic Equation

On substituting the value we obtain

➥ 0² = 20² + 2 × -8 × s

➥ 0 = 400 - 16 × s

➥ -400 = -16 × s

➥ 400/16 = s

➥ 25 = s

So, the squirrel is 25 metres from the car .
