Explanation:

Please find the complete question in the attached file.

The Radar is the instrument used to gather data from birds by researchers. This would be the primary tool to study the flight behavior of migrating birds with the impact of environmental influences including the ecology of migratory movements, from the broad population group for both the distribution of land areas and geomorphology as well as meteorological systems to the shift in the behavior of airlines of particular birds, especially when responding to lead routes.

Answer:

2.5x10^4 J (scientific notation)

25,000 (Acellus)

Equation:

Q=mcΔT

where:

Q=heat

m = mass

c = specific heat

ΔT=change in temperature

Any rearranging?

Let's see.

No, we need heat.

So no rearranging.

Plug in the numbers and solve

It takes approximately 28,224 joules of heat to raise 0.0438 kg of aluminum from room temperature to its melting point.

To calculate the heat required to raise the temperature of aluminum from room temperature to its melting point, we need to use the specific heat capacity formula: Q = m × c × ΔT

where:

Q = heat (in joules)

m = mass of aluminum (in kilograms)

c = specific heat capacity of aluminum (in joules per kilogram per degree Celsius)

ΔT = change in temperature (in degrees Celsius)

Given:

Mass of aluminum (m) = 0.0438 kg

Specific heat capacity of aluminum (c) = 900 J/kg°C (approximate value for aluminum)

Change in temperature (ΔT) = melting point (660°C) - room temperature (20°C) = 640°C

Now, let's calculate the heat (Q):

Q = 0.0438 kg × 900 J/kg°C × 640°C

Q = 28,224 J (joules)

So, it takes approximately 28,224 joules of heat to raise 0.0438 kg of aluminum from room temperature to its melting point.

Answer:

Ex = [tex]2 k q \frac{x}{(x^2 + z^2) ^{3/2}}[/tex] ,  E_z =0

Explanation:

To find the electric field of each charge, let's use

          E = k q / r²

where the field for a positive charge is outgoing and for a negative charge it is incoming.

Since the electric field is a vector magnitude, let's add its components at the point z

X axis

       Eₓ = E₁ₓ + E₂ₓ

       Eₓ = 2 E₁ₓ

Z axis

       E_z = E_{1z} -E_{2z}

       E_z= 0

Let's find the expression for the electric field

the distance from the charge to the test point, using the Pythagorean theorem is

      r² = (x-0) ² + (0-z) ²

      E = [tex]k \frac{q}{x^2 + z^2}[/tex]

with trigonometry we can find its components

      cos θ = E₁ₓ / E

      E₁ₓ = E cos θ

we substitute

     Eₓ = 2 E cos θ

where the cosine

    cos θ = x / r

     Ex = [tex]2 k \frac{q}{x^2 + z^2} \ \frac{x}{\sqrt{x^2 + z^2} }[/tex]

     Ex = [tex]2 k q \frac{x}{(x^2 + z^2) ^{3/2}}[/tex]

     E_z = 0

Answer:

the answers the correct one is C

Explanation:

In radioactive decay processes, a very important concept is the half-life time, which is the time it takes for the parent nuclei to decompose into child nuclei.

expressed this mathematically is

              N = N₀ [tex]e^{- \lambda t}[/tex]

for the average life time

              N₀ / 2 = N₀  [tex]e^{- \lambda T_{1/2}[/tex]

               T =[tex]\frac{ln 2x}{ \lambda}[/tex]

Analyzing this expression, the nuclei that decay are the so-called parents and the new nuclei called children appear.

Answer:

[tex]f=7.5\times 10^{14}\ Hz[/tex]

Explanation:

Given that,

The wavelength of light, [tex]\lambda=400\ nm=400\times 10^{-9}\ m[/tex]

The speed of light, [tex]c=3\times 10^8\ m/s[/tex]

We need to find the frequency of light. We know that,

[tex]c=f\lambda[/tex]

Where

f is the frequency

So,

[tex]f=\dfrac{c}{\lambda}\\\\f=\dfrac{3\times 10^8}{400\times 10^{-9}}\\\\f=7.5\times 10^{14}\ Hz[/tex]

So, the frequency of light is [tex]7.5\times 10^{14}\ Hz[/tex].

Add varying numbers of weights to M1 and measure the speed of the car.

Add varying numbers of weights to M2 and measure the speed of the cart.

In order to test the changing amount of force that is acting on the object has effect on the average speed of the object we have to change the amount of weight on the object and allows it to move to a certain point in this way we can check the effect of changing amount of weight on the speed of the object.

Answer:

[tex]6.42\ \text{m/s}[/tex]

Explanation:

v = Final velocity

u = Initial velocity = 0

s = Displacement of Tarzan's feet = 2.1 m

a = g = Acceleration due to gravity = [tex]9.81\ \text{m/s}^2[/tex]

From the kinematic equations we get

[tex]v^2-u^2=2as\\\Rightarrow v=\sqrt{2as+u^2}\\\Rightarrow v=\sqrt{2\times 9.81\times 2.1+0}\\\Rightarrow v=6.42\ \text{m/s}[/tex]

At the instant just before Tarzan's feet touch the ground the velocity of his feet are [tex]6.42\ \text{m/s}[/tex].

The speed at an instant just before Tarzen's feet touch the ground will be  

[tex]V=6.42\ \dfrac{m}{s}[/tex]

The speed of any body is defined as the movement of the body with respect to the time.

It is given in the question that

Mass of the Tarzen m=100 kg

The distance of the Tarzen's feet from the ground s=2.1 m

The acceleration due to gravity [tex]a=9.81\ \frac{m}{s^2}[/tex]

The speed of the Tarzen will be calculated by applying the equation of motion.

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

Since initial velocity is zero u=0

[tex]v^2=2as[/tex]

[tex]v=\sqrt{2as}[/tex]

[tex]v=\sqrt{2\times 9.81\times 2.1} =6.42 \ \frac{m}{s}[/tex]

Thus the speed at an instant just before Tarzen's feet touch the ground will be

Answer:

No, the car is decelerating  

Explanation:

No the car is decelerating if it exits a freeway and goes from 65

mph to 35 mph since the change in velocity is negative.

change in velocity = final - initial

change in velocity  = 35 - 65

change in velocity = -30mph

Since the change in velocity is negative, hence the car is decelerating. Deceleration is a negative acceleration

Answer:

24 N

Explanation:

Given,

Unstretched length or original length , x1 = 12cm

Stiffness constant, k = 8 N/cm

Load required to take spring to a length , x2 of 15cm

Recall the relation :

F = Ke

Where, e = extension

e = x2 - x1

e = (15 - 12) = 3

F = ke

F = 8 N/cm * 3cm

F = 24 N/cm*cm

F = 24 N

Hence, required load = 24 N

You will be able to tell whether the unknown cell is from an animal or from a plant through the knowledge of difference between plants and animal cells.

Explanation:

A cell can be defined as the simplest bit of living matter which exhibits a variety of shapes and sizes and that can exist independently.

When a slide of an unknown cell is studied under a microscope, different cell structures would be observed which would be used to conclude if the cell on the slide is a plant or animal cell.

The following features are observed in a plant cell:

--> cellulose cell wall is present

--> Chloroplast is present

--> A large central vacuole is present

--> Centriole is absent

The following features are observed in animal cell:

--> Cellulose cell wall is absent

--> Chloroplast is absent

--> Small vacuoles is present

--> Centriole is present

The difference between a plant and an animal cell can be seen from the features above and a clear knowledge of this will help the student tell whether the unknown cell is from an animal or from a plant.
