According to the graph the acceleration of the object is ?

A) Constant
B) decreasing
C) increasing
D) zero

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

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 :)

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!

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

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)

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.

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.

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.

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,

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

Answer:

all of these very easy questions

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

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.

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.

Answer:

The pressure inside the dropper is same as the atmospheric pressure when the rubber bulb is not pressed. ... But when we press the rubber bulb the pressure inside the dropper increases and hence the water flows out.  Atmospheric pressure acting from outside the dropper balances the pressure exerted by water and water does not come out of a dropper. On pressing the dropper inside pressure of water becomes more than outside atmospheric pressure and water run out. When we press the bulb of a dropper with its nozzle kept in water, air in the dropper is seen to escape in the form of bubbles. Once we release the pressure on the bulb, water gets filled in the dropper.
