Max and Jimmy continue jumping on a trampoline. When they jump at the same time, Max makes a wave crest and Jimmy makes a wave trough. What type of wave interaction occurred?

Answers

Answer:

The type of wave interaction occurred is destructive interference

Explanation:

Given that,

Max and Jimmy jump at same time.

Wave crest makes by Max and wave trough makes by Jimmy.

We need to find the type of wave interaction occurred

According to given data,

We know that,

If the wave crest and wave trough are interacted to each other then the interaction is destructive interference.

If the wave crest and wave trough are interacted with crest and trough then the interaction is constructive interference.

So, we can say that if the wave crest and wave trough are interacted to each other then the interaction is called destructive interference

Hence, The type of wave interaction occurred is destructive interference

Answer:

Answer:

The question is not complete, below is the completed question:

Watching your mother bake bread, you learned that the dough of the bread rises because yeast acts on the sugar and releases gas. You wonder whether the amount of sugar used will affect the size of the bread. That is, if you add more sugar, the size of the bread will be larger. Your mother’s recipe calls for 60 grams of sugar to produce a loaf of bread about 1260 cm3. What is the independent and dependent variables?

Answer:

independent variable: amount of sugar used

Dependent vairable: size of bread

Explanation:

In a scientific experiment, there are two main types of variables; independent and dependent variable:

Independent variable: This is the variable that is completely under the control and manipulation of the experimenter. The values of this variable can be varied at will, and the effect of the variation affects the dependent variable. In this example, the independent variable is the amount of sugar used, because the amount of sugar used is determined by the baker.

Dependent variable: The dependent variable is the variable that changes as a result of the manipulation of the independent variable. It is not directly under the manipulation of the experimenter, and it is the variable that the experiment seeks to study. In this example, the size of the bread is the dependent variable because it depends on the amount of sugar used.

Enzo investigated the effect of different types of fertilizers on the growth of bean plants. He hypothesized that fertilizer B would result in the greatest amount of growth. However, the results showed that the control plants without fertilizer had the greatest growth. Why was Enzo's data still valuable even though it did not support his hypothesis?

Find the horizontal and vertical displacement comments of 145m displacement of a superhero that flies from the top of a building at an angle of 28 degrees below the horizontal

Answers

Answer:

The horizontal and vertical displacement is 128.02 m and 68.07 m respectively.

Explanation:

Displacement, d = 145 m

The top of a building at an angle of 28 degrees below the horizontal

We need to find the horizontal and vertical displacement.

For horizontal displacement,

[tex]D_x=d\cos\theta\\\\D_x=145\times \cos(28)\\\\D_x=128.02\ m[/tex]

For vertical displacement,

[tex]D_y=d\sin\theta\\\\D_y=145\times \sin(28)\\\\D_y=68.07\ m[/tex]

So, the horizontal and vertical displacement is 128.02 m and 68.07 m respectively.

Answers

Answer:

26897.3 m

Explanation:

1 km = 1000 m

1 cm = 0.01 m

so the calculation will be

25873 m + 1024 m + 0.03 m= 26897.3 m

The sum of the given expression (25.873 kilometers ) + (1024 meters ) + (3.0 centimeters)  would be 26897.0 meters.

What are significant figures?

In positional notation, significant figures refer to the digits in a number that is trustworthy and required to denote the amount of something, also known as the significant digits, precision, or resolution.

As given in the problem we have to Calculate the following sum and express the answer in meters, by Following the rules for significant figures,

(25.873 kilometers ) + (1024 meters ) + (3.0 centimeters)

1 kilometers = 1000 meters

1 meter =100 centimeters

(25.873 ×1000×100) + (1024×100 ) + (3.0 centimeters)

                = 26897.03 centimeters

Thus ,the sum of the given expression (25.873 kilometers ) + (1024 meters ) + (3.0 centimeters)  would be 26897.0 meters.

185 N to the right
185 N to the left

Answers

Answer:

15 N to the right.

Explanation:

100 N to the right -->

85 N to the left <--

So therefore in order to find the net force of where the sled is being dragged towards is 100 N - 85 N = 15 N.

So the sled is moving towards the right of 15 N.

Analyse the circuit to answer the following questions.

(i) What kind of combination are the lamps arranged in (series or parallel)?

(ii) Explain with reference to your above answer, what are the advantages (any

two) of this combination of lamps?

(iii) Explain with proper calculations which lamp glows the brightest?

(iv) Find out the total resistance of the circuit.​

Answers

A parallel circuit, is one which the conductors leading into the bulbs are joined together on one side of the bulbs, and the conductors coming out of the bulbs are joined together on the other side of the bulb

The correct arrangement, advantages, lamp and resistance values are;

(i) The lamps are arranged in parallel(ii) Improved reliability Optimum performance of the bulbs(iii) Lamp C(iv) The total resistance is 4 Ω

The reason the above values are correct are as follows:

(i) From the diagram attached, the lamps are arrange in parallel

This is so because, each lamp is directly connected across the terminals of the the voltage source

(ii) The advantages of the bulbs arranges in parallel are;

The other lamps will continue working if one lamp becomes faultyThe voltage is applied directly to each lamp, such that the lamps are lit with the maximum power available in the circuit

(iii) The brightness of the lamp is given by the power of the lamp

The lamp with the highest wattage, or power glows the most

Power, P = Voltage, V × Current, I

The power for lamp A, [tex]P_A[/tex] = 60 V × 3 A = 180 W

The power for lamp B, [tex]P_B[/tex] = 60 V × 4 A = 240 W

The power for lamp C, [tex]P_C[/tex] = 60 V × 5 A = 300 W (Brightest)

The power for lamp D, [tex]P_D[/tex] = 60 V × 3 A = 180 W

Therefore, lamp C has the highest power and glows the brightest

(iv) The total resistance is given by the voltage, divided by the total current

Total current, I = 3 A + 4 A + 5 A + 3 A = 15 A

[tex]Total \ resistance, \ R_{tot} = \dfrac{V}{I_{tot}}[/tex]

Therefore;

[tex]Total \ resistance, \ R_{tot} = \dfrac{60 \, V}{15 \, A }}=4 \, \Omega[/tex]

The total resistance, R = 4 Ω
