A thesis should be a statement that can be argued.

Explanation:

How much voltage is required to run 0.054 A of current through a 15 2

resistor? Use AV = IR.

O A. 0.81 V

O B. 1.2 V

O c. 2.8x10²v

O D. 3.6 x 10-3 v

Answers

Answer:

The correct option is (a).

Explanation:

Given that,

Current flowing through the resistor, R = 0.054 A

Resistance of the resistor, R = 15 ohms

We need to find the voltage. We know that, Ohm's law gives the relation between voltage, current and resistance i.e.

V = IR

Put all the values,

[tex]V=0.054 \times 15\\\\V=0.81\ V[/tex]

So, the required voltage is equal to 0.81 volts.

Determine whether the interference is constructive or destructive at each location indicated.
A.constructive or destructive
B. constructive or destructive
C. constructive or destructive
D. constructive or destructive

Answers

Answer:

A. Constructive

B. Destructive

C. Destructive

D. Constructive

Explanation:

Constructive interference takes place at locations along the path of two superposed waves where the waves are in phase such that a high or low point of one of the waves corresponds with a high or low point of the other wave which gives a resulting wave amplitude which is the sum of the amplitudes of the individual waves

Destructive interference takes place at locations along the path of two superposed waves where one wave is out of phase with the other wave such that a high or low point of one of the waves coincides with a low or high point of the other wave respectively thereby cancelling the effect of the other wave and giving a resulting wave that has an amplitude which is the difference in the amplitudes of the individual waves

Therefore;

At point A, the peak of each wave partially coincides resulting in constructive interference

At point B, the peak of the blue wave and the trough of the red wave partially coincides resulting in destructive interference

At point C, the through of the blue wave and the peak of the back wave partially coincides resulting in destructive interference

At point D, the trough of each wave partially coincides resulting in constructive interference.

If 10.0 J of work are required to transfer 2.00 coulombs of
charge from point X to point Y in an electric field, what is the
difference in potential between these two points?

Answers

Answer: 5V

Explanation: because 2 goes into 10, five times. Also I know it’s correct cuz I got it right in my quiz

The difference in potential between these two points is 5 V.

Electric potential between the two points

The electric potential between two points is the work done in taking a unit postive charge from one point to another.

The difference in potential between these two points is calculated as follows;

W = qV

V = W/q

V = 10/2

V = 5 V

Thus, the difference in potential between these two points is 5 V.

A chocolate bar has nutritional energy content of 100KJ. If an 50kg mountain climber eats this chocolate bar and converts it all to potential energy. What altitude(height) can she climb on a mountain using this energy? Consider g=10m/s^2

Answers

Answer:

h = 200 m

Explanation:

The energy content of the chocolate is completely converted to the potential energy of the climber. Therefore:

[tex]Energy\ of\ Chocolate = Potential\ Energy\\Energy\ of\ Chocolate = mgh[/tex]

where,

m = mass of climber = 50 kg

Energy of Chocolate = 100 KJ = 100000 J

g = acceleration due to gravity = 10 m/s²

h = height = ?

Therefore,

[tex]100000\ J = (50\ kg)(10\ m/s^2)h\\\\h = \frac{100000\ J}{500\ N}[/tex]

h = 200 m

Pedro is planning to model how changes in weather affect evaporation from lakes. For his first experiment, he wants to test how humidity affects the evaporation rate. He places one beaker with 300 mL of water in a dry area, and he places another beaker with 300 mL of water near a humidifier. Which of the following variables does Pedro need to control during his experiment?

Answers

The aim of the experimental model is to test the effect of humidity (changes in weather) on evaporation (rates) from lakes

The control variables in an experiment are the variables that the experimenter intends to keep constant always so as to limit their effect on the measurements of the relationship between the dependent and the independent variable

Therefore in order to have a proper measurement of the effect of humidity on evaporation rate, other variables such as temperature, and the volume of the water in the experiment investigations which affect evaporation rate by the provision of heat, (temperature) and their heat capacity, (the volume and therefore, mass of water) should be controlled

A typical electromagnetic signal from a communications satellite might have an intensity of 0.600 pW/m2 at the surface of the Earth. Your satellite dish collects the energy of the electromagnetic signal from the satellite; then your dish passes that energy to its central receiver, where the signal can be processed by a circuit. The area of a satellite dish can be calculated from pi (3.1416) times the radius squared. If your satellite dish has a radius of 0.28 m, and if it is receiving the signal described above, how much electromagnetic energy is reflected to the central receiver in 2.5 minutes

principle of quantization of charge​

Answers

Charge quantization is the principle that the charge of any object is an integer multiple of the elementary charge. Thus, an object's charge can be exactly 0 e, or exactly 1 e, −1 e, 2 e, etc., but not, say, 12 e, or −3.8 e, etc.

Quantization is the process of replacing analog samples with approximate values taken from a finite set of allowed values.

Describe how the energy is transferred from the gas hob to cook the egg in the water.

Answers

Answer:

remember the ways in which the heat is transferred:

Conduction: Heat transfer of two objects touching.

Convection: Heat transfer in a medium with a gradient of temperature.

Radiation: Heat transferred between two objects that not touch each other (an example of this is how the Sun heats up the Earth)

First, we start with the gas itself.

It has a lot of pressure, so when you open the knob, the gas can get out.

The has chemical potential energy.

When you combust the gas, you transform that energy into heat energy, as the flame touches the pot, it starts o also heat the pot.

This heat energy is transferred to the pot, which transfers heat energy to the water by conduction, the heat in the water is "distributed" by convection, and as the water starts to heat up, the energy is transferred to the egg by conduction.
