What do you know about nuclear energy?
Answer:
Nuclear energy comes from splitting atoms in a reactor to heat water into steam, turn a turbine and generate electricity. Ninety-three nuclear reactors in 28 states generate nearly 20 percent of the nation's electricity, all without carbon emissions because reactors use uranium, not fossil fuels.

the right-hand tube of the manometer is open to the atmosphere. The pump has been operated so that the mercury levels differ, as shown, by 250 mm. The density of mercury is 13 600 kg / m3. i) Calculate the pressure, in Pa, due to the 250 mm column of mercury.
Answer:
P(ressure) = d g h = density * gravity * height
P = 13600 * 9.8 * .25 = 33,300 Pa
Check: 1 atm = 76 cm = 760 mm height = 1.01 * 10E5 Pa
h = 1.01 * 10E5 / 9.8 * 13600 .758 m = 758 mm for 1 atm
250 / 758 = 1/3 atmosphere = 33,700 Pa close enough for estimates
(the pressure requested is 1/3 atmosphere where 1 atm = 760 mm Hg)
A brick is 32cm long and 10cm wide. It weighs 16N and is lying on the ground. Find the pressure exerted by the brick on the ground.
Answer:
Below
Explanation:
First, we need to convert the dimension from cm to m before plugging it into the equation:
32 / 100 = 0.32 m
10 / 100 = 0.1 m
You can use this equation to find the pressure exerted on the ground
Pressure = Force / Area
Plugging our values in.....
Pressure = 16 Newtons / (0.1)(0.32)
= 16 Newtons / 0.032
= 500 N/m^2
Hope this helps! Best of luck <3
Describe how you would measure the Volume of an irregular solid object.
You can include any apparatus and equations.
Answer:
Find a recipient that you can put the object completely inside, and fill this recipient with water. After, you put the irregular solid you want to measure the volume inside, and the water will spill out the recipient. So you take the water that spilled out and uses a graduated recipient to measure the volume of water. The volume of the solid will be exactly the same volume of water that spilled of the first recipient

how is light reflected from a prism
Answer:
White light entering a prism is bent, or refracted, and the light separates into its constituent wavelengths. Each wavelength of light has a different colour and bends at a different angle. The colours of white light always emerge through a prism in the same order—red, orange, yellow, green, blue, indigo, and violet.

how is circuit used to make permanent magnet
Answer:
The touch in a circuit is by forming a circuit with the bars, and moving the horseshoe magnet backwards and forwards upon it. Between the two poles a strong current is excited, & on moving the magnet around we magnetize the bars to saturation i.e. to as a high degree as the bar is capable of retaining.

What does v or vf stand for? What SI units are used to measure it?
Answer:
Below
Explanation:
In my experience, vf means final velocity, and v would be the average velocity!
You would write it as ΔV (delta V)
The SI units that are used to measure it are m/s
Hope that helped!
v and vf stand for velocity and final velocity respectively. its SI unit is to measure it is m/s.
What is velocity & Acceleration ?Velocity is "rate in change of displacement with respect to time".
i.e. v= dx/dt. It is denoted by v.
it is also defined as displacement divided time. i.e. v= Displacement÷Time.
Velocity shows how much distance can be covered in unit time. It's SI unit m/s.
Acceleration is rate in change of velocity with respect to time.
i.e. a = dv/dt
if an object changes its velocity in short time, we can say that it has greater acceleration.
a= dv/dt =Δv/Δt = [tex]\frac{v_{i} - v_{f} }{t_{i}-t_{f} }[/tex]
where [tex]v_{i}[/tex]= initial velocity of an object
[tex]v_{f}[/tex]= final velocity of an object
t₂= initial time of an object
t₁ = final time of an object
Hence v is stands for velocity and vf is stand for final velocity,

Answer:
36 mph.
Explanation:
Now Albert here is using the wind to his advantage but if say there was no wind then he would not have the 6 mph behind him so we subtract 6 from 40 to get 36. hope this helps :)
A student uses the right-hand rule as shown.
What is the direction of the magnetic field in front of the wire closest to the student?
O up
Oright
O down
O left
Answer: O:right
Explanation: In this case you place your finger on the current, and your fingers should curl showing the way, you must use your right hand in this case, otherwise that would mean the fingers on your left would bend way back, and snap off, (Not really lol, just saying)
The direction of the magnetic field in front of the wire closest to the student is right. Thus, the correct option is B.
The direction of the magnetic field encircling a current-carrying wire can be determined using the right-hand rule. The magnetic field's direction is shown by the direction in which your fingers wrap around the wire if you point your right thumb in the direction of the current.
In this case, the student is using the right-hand rule with their thumb pointing upward. This means that the direction of the current is flowing into the page, perpendicular to the direction of their thumb.
To determine the direction of the magnetic field in front of the wire closest to the student, we can curl our fingers around the wire in the direction of the current (into the page) while keeping our thumb pointing upward. This results in the direction of the magnetic field being to the student's right.

If a ball is rolling at a velocity of 1.5 m/s and has a momentum of 10.0 kg times m/s, what is the mass of the ball?
Answer:
Mass of the ball, M = 6.667 kg
Explanation:
Given data:
Momentum, Mo = 10.0 kgm/s
Velocity of the rolling ball, V = 1.5 m/s
Mass of the body, M = ?
Momentum, Mo = Mass, M x Velocity, V
10.0 kgm/s = M x 1.5 m/s
Divide each side by 1.5 m/s
M = 10.0 kgm/s / 1.5 m/s
M = (6⅔) kg
:. Mass of the ball, M = 6.667 kg
6. 498.82 mg comverted to kg
Answer:
0.00049882 kg
........................
Answer:
498.82 mg=0.00049882 kg
Explanation:
To get this answer, you must multiply the quantity of mg by 0.000001, which is also 0.001². Since one gram is 1000 mg, and 1000 g is 1 kg, you must divide the amount of mg by one million, or multiply by 1/1000000, or 0.000001. I hope this helped you. Enjoy your day, and take care!
in the Newton's Third Law of Motion state three characteristics
Answer:
Newton's third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A. This law represents a certain symmetry in nature: forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself.
The P.E stored by a mass spring system at an extension of 2 cm is 10 J. The P.E stored by the same system at an
extension of 4 cm will be:
Explanation:
extension(x) = 0.02m When the P.E is 10J.
extension(x)= 0.04m PE?.
P.E is proportional to Extension²
P.E/x² = P.E"/x"²
10/(0.02)² = P.E/(0.04)²
P.E= 10x(0.04)²/(0.02)²
P.E= 40J
