[tex]b=\frac{1}{2}[/tex] and [tex]a=-\frac{1}{2}[/tex]

Explanation:

The velocity longitudinal waves depends on the bulk modulus and the density. It is given by the formula:

[tex]V=\sqrt{\frac{\beta }{\rho} }[/tex]

Where V is the velocity , β is the bulk modulus and ρ is the density.

[tex]V=\sqrt{\frac{\beta }{\rho} }\\V=\frac{\beta^\frac{1}{2} }{\rho^\frac{1}{2} } \\V=\beta^\frac{1}{2} \rho^-\frac{1}{2}[/tex]

Therefore comparing with [tex]V =E ^b d ^a[/tex], where V, E and d are the velocity longitudinal waves, bulk modulus of elasticity and density, the values of b and a can be gotten.

Therefore, [tex]b=\frac{1}{2}[/tex] and [tex]a=-\frac{1}{2}[/tex]

Answer:

The organisms Rachel see are all inter dependent on one another to survive in the form of a food chain. This relationship helps the swamp ecosystem thrive.

Explanation:

In this swamp ecosystem, the Sandhill crane relies on the fishes for food, Some of the fishes rely on the algae or the snail for food and the snail also rely on the algae for food. This relationship not only serves to nourish the organism above the food chain but serves a general purpose of controlling the ecosystem. The absence of one or more of these organisms, say the algae can offset the ecosystem in a chain reaction that might go as far as affecting the cranes. Also, the absence of algae feeders can lead to an algae boom which might overpower the oxygen concentration in the pond further killing other organisms in the pond that need oxygen for respiration.

Answer:

The Answer is B

Explanation: The loudness is shared among the listener and source

Answer : The correct option is, (B)

Explanation :

There is a direct relation between the loudness of sound and the intensity of sound.

[tex]L=10 log \frac{I}{Ia} }[/tex]  ..........(1)

where,

L = loudness of sound

I = intensity of sound

= intensity of reference

From this we conclude that the loudness is directly proportional to the intensity of the sound.

There is an indirect relation between the intensity of sound and the distance of the listener from the source.

[tex]\frac{I_1 }{I_2 } = (\frac{d_1}{d_2} )^{2}[/tex]   ...................(2)

From this we conclude that the intensity of sound is inversely proportional to the square of the distance of the listener from the source.

From equation (1) and (2) we conclude that the loudness of sound is inversely proportional to the square of the distance of the listener from the source.

Hence, the correct option is, (B)

Answer: [tex]75000kg*m/s[/tex]

Explanation:

[tex]p=mv[/tex]

where;

p = momentum

m = mass = 3000kg

v = velocity = 25m/s

--------------------------------------------------------------------------------------------------

The first thing we need to do is convert 90km/h to m/s. Our conversion factors here are: 1km = 1000m and 1h = 3600s

[tex]90km/h(\frac{1000m}{1km})(\frac{1h}{3600s} )=25m/s[/tex]

Plug your values in the formula:

[tex]p=(3000kg)(25m/s)\\p=75000kg*m/s[/tex]

Answer:

The difference between mass and weight is that mass is the amount of matter in a material, while weight is a measure of how the force of gravity acts upon that mass. Mass is the measure of the amount of matter in a body. ... Weight usually is denoted by W. Weight is mass multiplied by the acceleration of gravity.

Answer:

mass is present in the substance and weight is the force exerted by gravity

substances will move faster and become warm to the touch.

Explanation:

when the radiation from the sun comes down and hits substances, the substances absorbs the radiation making them warm. the absorbed energy is transformed into heat energy. this heat energy plays an important role in regulating the temperature of the Earths crust, surface waters, and low atmosphere.

homes and cars

Explanation:

There are many devices in our day to day lives that use circuits in order to function. Aside from all those that are listed in the question some others include, our entire homes and cars, with the main difference being the amount of voltage that is being used. Just like tv's and computers, houses and cars use electrical circuits on a much larger scale in order to provide electricity to different parts of the system.

Answer: i dont really get what u are asking but here is what im guessing u mean.

Explanation:Refer to the diagram shown below.

m = 50 g = 0.05 kg, the mass of the ball

A = 6 cm = 0.06 m, the amplitude

The oscillatory motion relative to the equilibrium position is

x(t) = A cos(ωt)

where

x =  displacement at time t

A = amplitude, 0.06 m

ω = circular frequency

Therefore

x(t) = A cos(ωt)

The velocity function is

v(t) = - ωA sin(ωt)

The maximum velocity occurs when sin(ωt) = 1. Because the maximum velocity is 3.2 m/s, therefore

(ω 1/s)*(0.06 m) = (3.2 m/s)

w = 53.33 1/s

Therefore

x(t) = 0.06 cos(53.33t)

v(t) = 3.2 sin(53.33t)

When the spring is compressed by 4.5 cm (0.045 m) from the equilibrium position, then

0.06 cos(53.33t) = -0.045

cos(53.33t) = -0.75

53.33t = cos⁻¹ (-0.75) = 2.4189

t = 0.0454 s

The velocity when t = 0.0454 s is

v = 3.2 sin(53.33*0.0454) = 2.111 m/s

The kinetic energy is

KE = (1/2)*m*v²

    = 0.5*(0.05 kg)*(2.111 m/s)²

    = 0.1114 J

Answer:  0.1114 J

When the toy is at the highest point of its motion, its velocity is zero and its acceleration is negative.

Any projectile's instantaneous speed at its maximum height is zero. Because gravity gives the ball the same acceleration on the way up as it does on the way down, the time it takes to reach maximum altitude is the same as the time it takes to return to its launch position.

Because of the -ve acceleration along the vertical direction, velocity decreases until it reaches zero.

The velocity of a projectile is zero at its highest point. A projectile's acceleration is zero at its highest point.

When going up, the acceleration is negative because the speed is decreasing. When going down, the acceleration is negative because it is moving in the opposite direction, down.

Thus, When the toy is at the highest point of its motion, its velocity is zero and its acceleration is negative.

Answer:

Polygenic because a trait is controlled by three different  genes

Explanation:

In the given question, the diagram of the question is not found anywhere therefore the question has been answered based on previous knowledge.

The traits of an organism are determined by the sequences of nucleotide present on the DNA called genes. One gene-one protein hypothesis suggests that usually one trait is determined by 2 alleles of a gene but there are few traits which are either determined or influenced by more than one gene.

These traits are known as the polygenic trait as the traits are controlled by more than one or "poly (many) genes" like human eye color, height, and others.

Thus, the selected option is the correct answer.

Polygenic because a trait is controlled by three different  genes

Pressure = 1400 pascals

Explanation:

The formula to measure pressure is Pressure equals force in pounds over the area in square inch. The written abbreviated formula is P= F/A. By looking at the formula one can see that top obtain the pressure on an object, one must divide the the force by the area of an object.

P = 140/0.1

P = 1400

[tex]\\ \rm\longmapsto Pressure=\dfrac{Force}{Area}[/tex]

[tex]\\ \rm\longmapsto Pressure=\dfrac{140}{0.1}[/tex]
