Answer:
The temperature after the water is heated is higher by 152°F
Explanation:
The starting temperature of a beaker of water = 60 F
Temperature of water in heated condition = 212°F
The temperature rises by 212°F - 60°F = 152°F
The temperature after the water is heated is higher by 152°F

circumference?
Answer:
The circumference of a circle is the distance around it (linear) while a period is the completion of a cycle or the length from one peak to the next of a periodic function
Explanation:
Circumference is the distance around a circle while period is the time taken for one revolution around the circle.
What is a Circle?This is a round plane figure whose points are equidistant from a fixed point. The circumference is total distance round the circle.
On the other hand, period refers to the time taken for one revolution around the circle.

A spring is stretched 0.15 m and the force was 1500 N. What is the spring constant?
The spring constant for a spring is stretched 0.15 m and the force was 1500 N is 10000.
What is spring constant?The spring constant, k, is a measure of the spring's stiffness. It varies depending on the spring and material. The greater the spring constant, the stiffer the spring and more difficult to stretch.
The letter k symbolizes the "spring constant," which is a number that tells us how "stiff" a spring is.
If k is large, it means that more force is required to stretch it a certain length than would be required to stretch a less stiff spring the same length.
We know that,
F = k(x)
Where k is the spring constant.
Here, it is given that:
F = 1500N
x = 0.15m
So,
1500 = k (0.15)
k (0.15) = 1500
k = 1500/0.15
k = 150000/15
k = 10000
Thus, the value of spring constant is 10000.

You are adding sugar to a cup of tea. What could you do to make the sugar dissolve
faster? (Select all that apply)
Stir/agitate
Heat the tea
Break the sugar into smaller parts
Keep adding more sugar
Answer:
Stir/agitate and heat the tea
Answer:
Stir the tea, Heat the tea, and Grind the sugar
Explanation:
Heating and stirring both increase the energy of the tea molecules, which increases interactions with the sugar. Grinding sugar allows more sugar molecules to be exposed to the solvent particles that dissolve them.
When a 6 Ω resistor is connected across the terminals of a 3 V battery, the number of coulombs passing through the resistor per second is
Answer:
Given that - R = 6 ohm
V = 3 volt
n = ?
so by ohms law , V = I X R
I = V \ R = 3 \ 6 = 0.5 A
we know that I = Q / T here t is 1 sec
Q = I X T = 0.5 X 1 = 0.5 C
By the law of quantization ,
Q = n x e
n = Q / e = 0.5 / 1.6 x 10 ^-19
n = 0.3125 x 10^19

Describe what happens to a moving object if NO forces are acting on it
Answer:
An object with no net forces acting on it which is initially at rest will remain at rest. If it is moving, it will continue to move in a straight line with constant velocity. Forces are "pushes" or "pulls" on the object, and forces, like velocity and acceleration are vector quantities.

A plumber is going to put two pipes in a wall, one in front and one in back. The pipes will be touching once they are installed. Both pipes are the same size and have the same number of molecules. The diagram above shows the pipes now, before they have touched. Use the information in the diagram to answer the question.
How does the temperature of the front pipe compare with the temperature of the back pipe before the pipes touch? What will happen after the pipes have been touching for a while?
Answer:
They become the same exact tempature
Explanation:
Since they got connected it should be the same.
the temperature of the front pipe compare with the temperature of the back pipe before the pipes touch by using same temperature.
what is temperature ?Temperature is the measure of hotness or coldness expressed in terms of any of several arbitrary scales and it indicate the direction in which heat energy will spontaneously flow from a hotter body to a colder body.
It is not the equivalent of the energy of a thermodynamic system like burning match is at a much higher temperature than an iceberg whereas the total heat energy contained in an iceberg.
Temperature which is similar to pressure or density known as intensive property that is independent of the quantity of matter is considered as distinguished from extensive properties, such as mass or volume.

A 25 N force stretches a spring 0.280 m. What was the spring constant?
Answer:
the spring constant is -89.2857 n/m
Explanation:
The computation of the spring constant is shown below:
As we know that
Force in newtons = Spring constant × amount of extension
F = -k × x
where
F = 25 N
And, x = 0.280m
So, the spring constant would 2
= 25N ÷ 0.280 m
= -89.2857 n/m
Hence the spring constant is -89.2857 n/m

In regions of the cardiovascular system where there is steady laminar blood flow, the shear stress on cells lining the walls of the blood vessels is about 20 N / M2. If the shear strain is about 0.008, estimate the shear modulus for the affected cells.
Answer:
Shear Modulus = 2500 Pa = 2.5 KPa
Explanation:
The shear modulus is defined as the ratio between the shear stress and the shear strain. Hence, the shear modulus, in this case, can be calculated by the use of the following formula:
[tex]Shear\ Modulus = \frac{Shear\ Stress}{Shear\ Strain}\\[/tex]
we have,
shear stress = 20 N/m²
shear strain = 0.008
Therefore,
[tex]Shear\ Modulus = \frac{20\ N/m^2}{0.008}\\\\[/tex]
Shear Modulus = 2500 Pa = 2.5 KPa

Explanation:
An effect analogous to two-slit interference can occur with sound waves, instead of light. In an open field, two speakers placed 1.19 m apart are powered by the same function generator producing sine waves at 1,163 Hz frequency. Assume that the speed of sound is 340 m/s. A student walks along a line 12.5 m away and parallel to the line from one speaker to the other speakers. She hears an alternating pattern of loud and quiet, due to constructive and destructive interference. What is the distance between the central maximum and the first maximum (loud) position along this line in m
Answer:
3.04 m
Explanation:
The interference by diffraction of waves is noticeable only when the dimension of the opening through which the wave is passing through is comparable to the wavelength of the passing wave.
It is given that :
Distance between two speakers, d = 1.19 m
Speed of sound, v = 340 m/s
The frequency is f = 1163 Hz
Distance the student walk along the line of the speaker, D = 12.5 m
We know the wavelength of the sound produced by the speakers is given by :
[tex]$\lambda=\frac{v}{f}$[/tex]
[tex]$=\frac{340}{1163}$[/tex]
= 0.29 m
Now the distance between the central maximum and the first maximum position is given by :
[tex]$y=\frac{\lambda D}{d}$[/tex]
[tex]$=\frac{0.29 \times 12.5}{1.19}$[/tex]
= 3.04 m

True or false. In a parallel circuit the current remains the same everywhere.
A.False
B. True
Answer:
Its False
Explanation:
In parallel circuits the current splits up so each branch has a different effective resistance (in each of the separate branches one can use the series rule again). Due to this, the current isn't the same everywhere in a parallel circuit.

A 100 N force is applied to move an object a horizontal distance of 5 meters at constant speed in 10 seconds. How much power is done?
The power used when a 100 N force is applied to move an object through a distance of 5 m at constant speed in 10 seconds is 50 W
We'll begin by calculating the energy. This can be obtained as follow:
Force (F) = 100 N
Distance (s) = 5 m
Energy (E) =?E = F × s
E = 100 × 5
E = 500 JFinally, we shall determine the power. This can be obtained as follow:
Energy (E) = 500 J
Time (t) = 10 s
Power (P) =?[tex]P = \frac{E}{t}\\\\P = \frac{500}{10}[/tex]
P = 50 WTherefore, the power used in moving the object is 50 W.
