<span>Radians/second * seconds = Radians BUT the angular velocity is not constant in this case so we need to integrate ω over time. We know this integral is the area under the curve which we can find using the plot: 20rad/s*2s + (10+5) + 10*0.4 = 59 radians 59 radians * 1rev/2π radians = 59/2π = 9.4 revolutions</span>

Answer:

mgh₁ + ½mv₁² = mgh₂ + ½mv₂²

Explanation:

Initial total energy = final total energy

PE₁ + KE₁ = PE₂ + KE₂

mgh₁ + ½mv₁² = mgh₂ + ½mv₂²

ioda

Answer:

b) field is zero,  c) the magnetic field does not change in intensity or direction

e) M = -H = Bo /μ₀ ,  g)  M = 0

Explanation:

Part b

superconductors are formed by so-called Coper pairs that are electrons linked through a distortion in the network, this creates that they must be treated as an entity so we have an even number of charge carriers and the material must behave with diamagnetic , Meissner effect, consequently the magnetic field inside its superconductor is zero

the correct answer is Zero

Part c

 outside the superconducting cylinder the magnetic field does not change in intensity or direction

Part E

Magnetization is defined by the equation

       B = μ₀ (H + M)

with field B it is zero inside the superconductors

        M = -H = Bo /μ₀

         

where Bo is the magnetic induction in the normal state

Part g

 As outside the cylinder there is no material zero magnetization

        M = 0

What type of energy is released when a firecracker explodes
Ludmilka [50]

-- Sound energy.  That's how you hear it explode.

-- Light energy.  That's how you see it in the sky.

-- Heat energy.  That's why you get burned if sparks fall on you.

-- Potential energy, as all the pieces fall to the ground.

These were all stored in it as chemical energy before it exploded.

Which energy transformation occurs when you light a gas burner?​
Eddi Din [679]

Answer:

Chemical energy to thermal(heat) energy

Explanation:

A gas burner contains chemical hydrocarbon such as methane, this methane is highly flammable.

The gas burner which contains methane when lighted up converts the chemical energy in the chemical to heat energy through the fire it produces. The fire then helps in heating up the surface it is applied to.
