Answer:

PAPER CLIPS ON NOSE OF A PAPER AIRPLANE

Purpose: To determine if the number of paperclips on the nose of a paper airplane affects the velocity and speed, measured in meters per seconds.

Make a Hypothesis Based on the Learning Thus Far: If the number of paperclips on the nose of a paper airplane increases, then the speed will _increase______ (increase, decrease, stay the same) in a __linear_______ (linear, exponential, logarithmic) mathematical relationship, and the velocity will (increase, decrease, stay the same) in a __exponential____ (linear, exponential, logarithmic) mathematical relationship. (Fill in the appropriate words for your hypothesis.)

Pictures: Insert at least 3 pictures of yourself conducting the experiment into this lab report. At least 2 pictures must show your face as you conduct the investigation. You may need to ask someone to help take these photos.

The sun emits energy in the form of electromagnetic waves produced by nuclear reactions deep in the sun's interior. Assume that

tatiyna

Answer:

I = W / 4π R_{s}², P = W / 2π c R_{s}², Io /I_{earth} = 10⁴

Explanation:

The intensity is defined as the ratio between the emitted power and the area of the spherical surface

I = P / A

Since the emitted power is constant and has a value of W for this case, let's look for the area of the sphere on the surface of the sun

A = 4π $R_{s}$ ²

I = W / 4π R_{s}²

.- The radiation pressure for total absorption is

P = S / c

Where S is the Pointer vector that is equal to the intensity

Let's replace

P = W / 2π c R_{s}²

.- We repeat for r = R_{s}/2

I₂ = W / 4π (R_{s}/ 2)²

I₂ = 4 W / 4π R_{s}²

I₂ = 4 Io

I₀ = W / 4piRs2

We calculate the radiation pressure

P₂ = I₂ / c

P₂ = 4 I₀ / c

P₂ = 4 (W / 4pi c Rs2)

.- the relationship between these magnitudes is

I₂ / I₀ = 4

P₂ / P₀ = 4

Let's calculate the intensity on the surface where the Earth is

r = 1.50 10¹¹ m

$I_{earth}$ = W / 4π r²

Io / I_{earth} = r² / $R_{s}$ ²

Io /I_{earth} = (1.5 10¹¹ / 6.96 10⁸) 2

Io /I_{earth} = 4.6 10⁴

Io /I_{earth} = 10⁴

8. A student does 1,000 J of work when she moves to her dormitory. Her internal energy is decreased by 3,000 J. Determine the he

Lyrx [107]

Answer:

The heat loss during the process = -4000 J

Explanation:

Work done by the student (W) = - 1000 J

Negative sign on the system is due to work done on the system.

Decrease in internal energy (U) = - 3000 J

We know that heat transfer in the system is given by (Q) = U + W

⇒ Q = - 1000 - 3000

⇒ Q = - 4000 J

This is the value of heat transfer during the process And negative sign indicates that heat loss during the process.

A car travels 20 km South, then turns and travels 30 km East? What is the total displacement?

Ne4ueva [31]

Answer:

Explanation:36.05 km

Given

First car travels $r_1=20\ km$ South

then turns and travels $r_2=30\ km$ east

Suppose south as negative y axis and east as positive x axis

So, $r_1=-20\hat{j}$

$r_2=30\hat{i}$

Displacement is the shortest between initial and final point

Dispalcement $=r=r_1+r_2$

Displacement $=-20\hat{j}+30\hat{i}$

Displacement $=30\hat{i}-20\hat{j}$

Magnitude $=\sqrt{30^2+(-20)^2}$

Magnitude $=36.05\ km$
