Answer 1

Answer:

The wavelength is 1.7cm

Explanation:

Given

See attachment for wave pattern

Required

What is the wavelength

To do this, we simply calculate the distance between successive waves (see attachment 2 for point A and B)

Using the ruler, points A and B are at:

[tex]A = 0.6cm[/tex]

[tex]B = 2.3cm[/tex]

So, the wavelength is:

[tex]\lambda = B - A[/tex]

[tex]\lambda = 2.3cm - 0.6cm[/tex]

[tex]\lambda = 1.7cm[/tex]

If approximated, the wavelength is:

[tex]\lambda \approx 2cm[/tex]

The energy transferred to the water in 100 seconds was 155 000 J. specific heat capacity of water = 4200 J/kg °C
Determine the mass of water in the kettle.
Use Figure 10.
Give your answer to 2 significant figures.
Any help would be appreciated

Answers

Answer:

0.37 kg

Explanation:

I'm not a professor myself, but this is how I worked it out:

using the graph, after 100 seconds, the temperature is 100 degrees Celsius.

If we now substitute everything into the specific heat capacity equation, making the mass "m", we would come up with:

4200 = 155000/(m x 100)

If we rearrange and solve for m, we get 0.37 kg.

I'm not sure if I have done this correctly, feel free to correct me.

Hope this helps!

By using the specific heat capacity formula, the  mass of water in the kettle is 0.47 kg

Give that the energy transferred to the water in 100 seconds was 155 000 J and the specific heat capacity of water = 4200 J/kg °C

From the graph;

The initial temperature of the water at time zero is 22 degree Celsius

The final temperature of the water at time 100s is 100 degree Celsius

Change in temperature (T) = 100 - 22 = 78 degree Celsius

To determine the mass of water in the kettle, use the heat energy formula below

E = mcT

Substitute all the parameters into the equation

155000 = 4200 x 78 M

Make M the subject of the formula

M = 155000/327600

M = 0.47 kg

Therefore, the  mass of water in the kettle is 0.47 kg

A - 28.4-μC charge is placed 16.4 cm from a charge q, the force between the two charges is 1240 N. What is the value of q?

Answers

Answer:

1.31×10⁻⁴ C or 131 μC

Explanation:

From the question,

Applying Coulomb's Law,

F = kqq'/r²..................... Equation 1

Where F = Force between the charges, q = first charge, q' = second charge, r = distance between the charges, k = coulomb's constant.

make q' the subject of the equation

q' = F×r²/(kq)

q' = Fr²/kq................ Equation 2

Given: F = 1240 N, r = 16.4 cm = 0.164 m, q = 28.4 μC = 2.84×10⁻⁵ C,

Constant: k = 8.98×10⁹ Nm/C²

Substitute these values into equation 2

q' = (1240×0.164²)/[(2.84×10⁻⁵)×(8.98×10⁹)

q' = (33.35104)/(25.5032×10⁴)

q' = 1.31×10⁻⁴ C

q' = 131 μC

A window cleaner has a weight of 839.86 N. The window cleaner is cleaning windows on the 4th floor of a building at a height of 12 m. How much potential energy does the window cleaner have?

Answers

Answer:

E = 10078.32 J

Explanation:

Given that,

The weight of a window cleaner, F = 839.86 N

The window cleaner is cleaning windows on the 4th floor of a building at a height of 12 m.

We need to find the potential energy of the window cleaner. We know that the potential energy of an object is given by :

E = mgh

Put values,

E = 839.86 × 12

E = 10078.32  J

So, the window cleaner will have 10078.32  J of potential energy.

The mass of an object is 84 kg. Find its weight on the Earth and the Moon.​

Answers

Answer:

We would take the mass given, 80 kg, and multiply it times the acceleration of Earth's downward pull on that mass, 9.8 m/s/s. So the weight on Earth is 784 newtons. So the weight of the same 80 kg mass on the moon is 133.28 N.

hi

mass is express  in Newtons.

On Earth gravity is  9.807   so  wieght would be :   9.807 * 84= 823.79

On the Moon garvity is  1.62  so weight would be  :  84 *1.62 = 136.08

A negative 6 mC charge enters a region of 45 T magnetic field that is directed up. If the charge is moving toward the south with a speed of 400 m/s

Answers

Question: A negative 6 mC charge enters a region of 45 T magnetic field that is directed up. If the charge is moving toward the south with a speed of 400 m/s. determine the magnitude and  direction of the force

Answer:

Magitude of F = 108 N

Direction: Perpendicular to the plane containing v and B.

Explanation:

From the question,

Since the velocity of the charge(v), is parallel to the field(B).

Therefore, We apply

F = qvB..................Equation 1

Where F = Force, B = magnetic field, v = velocity, q = Charge.

Given: q = 6 mC = 0.006 C, v = 400 m/s, B = 45 T

Substitute these values into equation 1

F = 0.006×400×45

F = 108 N.

The direction of the force is always perpendicular to the plane containing v and B.

a hot iron bar is placed 100ml 22C water. the water temperature rises to 32C. how much heat did the water gain and how much heat did the iron bar lose? Q=change T x C x M

Answers

Answer:

Water gained: 10Iron lost: -10

Explanation:

Given: Hot iron bar is placed 100ml 22C water, the water temperature rises to 32C

To find: How much heat the water gain, how much heat did the iron bar lost

Formula:Q = change T x C x M

Solve:

How much heat water gained

Initial heat = 22, then rose to 32. To find how much heat the water gained, simply subtract the current heat by the initial heat.

                                              32 - 22 = 10

The water gained 10 amounts of heat.

How much heat Iron lost

Current heat = 32, then dropped to 22. To find how much heat the Iron lost, simply subtract the initial heat by the current heat.

                                                   22 - 32 = -10

The Iron lost -10 amounts of water.

The number of waves produced by the musical instrument during the given time is 148 waves.

What is meant by frequency of a wave ?

Frequency of a wave is defined as the number of oscillations completed by the wave in one second.

Here,

The frequency of the wave, f = 370 Hz

That means the wave completes 370 oscillations in 1 second. Or 370 waves are produced by the musical instrument in 1 second.

The time taken by the instrument to produce waves, t = 0.4 s

Therefore,

The number of waves produced by the musical instrument during this time is,

n = f x t

n = 370 x 0.4

n = 148

Hence,

The number of waves produced by the musical instrument during the given time is 148 waves.
