Answer: the wasp’s stinger - protection against predators

the peacock’s bright plumage - attraction to obtain a mate

the owl’s large eyes - help to search for food

the bear’s fur - maintain homeostasis

Explanation:

An adaptation can be define as any change that occurs in the morphology, physiology and genetic make up of the organism which makes it suitable for survival in it's natural environment even in adverse conditions and reproduce.

The following are the adaptations with their benefits.

the wasp’s stinger - protection against predators

The wasp stinger generally exhibit toxic substance or allergy causing agent which the wasp use when it finds a predator around it.

the peacock’s bright plumage - attraction to obtain a mate

The male peacock exhibit bright and showy feathers which is a phenotypic advantage for attraction of female mates for copulation. This phenomena is called as sexual selection.

the owl’s large eyes - help to search for food

The owl's large eyes allows the night vision. There are many rods and cones present in the eyes of the owl so as to allow better vision in night and allow it to observe and capture prey.

the bear’s fur - maintain homeostasis

The bear's fur are insulating in nature that means it does not allow the entry of external air. Hence, helps in retaining the heat in the body in otherwise cold environment. Therefore, helps in maintaining the homeostasis (the tendency of the body retain it's constant internal environment as compared to changing external environment).

A spring with constant k = 78 N/m is at the base of a frictionless, 30.0°-inclined plane. A 0.50-kg block is pressed against the
olasank [31]

Explanation:

The given data is as follows.

   Spring constant (k) = 78 N/m,     \theta = 30^{o}

 Mass of block (m) = 0.50 kg

According to the formula of energy conservation,

                mgh sin \theta = \frac{1}{2}kx^{2}

       h = \frac{1}{2} \times \frac{kx^{2}}{mg Sin \theta}

          = \frac{78 \times 0.04}{2 \times 0.5 \times 9.8 \times 0.5}

          = 0.64 m

Thus, we can conclude that the distance traveled by the block is 0.64 m.

A sound wave traveling downward with a speed of about 4,000 m/s suddenly slows to 1,500 m/s not far below the Earth’s surface. W
mezya [45]
<h2>Answer: an underground lake</h2>

Explanation:

In general, sound (mechanical waves) travels faster in solids than in liquids, and faster in liquids than in gases. This is because <u>the speed of the mechanical waves is determined by a relationship between the elastic properties of the medium </u>in which they are propagated and the mass per unit volume of the medium (that is:<u>density</u>).

In other words: The speed of sound varies depending on the medium through which the sound waves travel.

So, if we are told the sound wave initially had a speed of 4,000 m/s and it suddenly decreases to 1,500 m/s, this means the sound waves passed from a solid medium to a liquid medium.

Hence, the correct option is: an underground lake.

Train cars are coupled together by being bumped into one another. Suppose two loaded train cars are moving toward one another, t
stellarik [79]

Answer:

0.243 m/s

Explanation:

From law of conservation of motion,

mu+m'u' = V(m+m')................. Equation 1

Where m = mass of the first car, m' = mass of the second car, initial velocity of the first car, u' = initial velocity of the second car, V = Final velocity of both cars.

make V the subject of the equation

V = (mu+m'u')/(m+m')................. Equation 2

Given: m = 260000 kg, u = 0.32 m/s, m' = 52500 kg, u' = -0.14 m/s

Substitute into equation 2

V = (260000×0.32+52500×(-0.14))/(260000+52500)

V = (83200-7350)/312500

V = 75850/312500

V = 0.243 m/s

An object moving on a horizontal, frictionless surface makes a glancing collision with another object initially at rest on the s
cluponka [151]

Answer:

Momentum is always conserved, and kinetic energy may be conserved.

Explanation:

For an object moving on a horizontal, frictionless surface which makes a glancing collision with another object initially at rest on the surface, the type of collision experienced by this objects can either be elastic or an inelastic collision depending on whether the object sticks together after collision or separates and move with a common velocity after collision.

If the body separates and move with a common velocity after collision, the collision is elastic but if they sticks together after collision, the collision is inelastic.

Either ways the momentum of the bodies are always conserved since they will always move with a common velocity after collision but their kinetic energy may or may not be conserved after collision, it all depends whether they separates or stick together after collision and since we are not told in question whether or not they separate, we can conclude that their kinetic energy "may" be conserved.
