The final temperature of the tea cup is 100°C.

<h3>What is internal energy?</h3>

The Internal energy is the energy of a substance due to to the constant random motion of its particles.

The symbol for internal energy of a substance is U and it is measured in Joules.

ΔU = q + W

  • q is the heat, q = mcΔT
  • W is the mechanical work.

In conclusion,  the final temperature of the tea cup at room temperature of 24 °C which is heated until it has twice the internal energy is 100°C.

Answer: When you break on your bike and when you rub your hands together to get warm.

Explanation: Force and friction affect our daily lives in numerous amounts of ways. For instance, when a football is kicked, it moves faster later after some time its force decreases due to friction. A common example of friciton is when a bike stops. When the brakes are applied the friction on the pads cause the bike to stop. The rubbing hands is making friction. Which makes you get warm.

You drop two balls of equal diameter from the same height at the same time. Ball 1 is made of metal and has a greater mass than
Lelechka [254]

Answer:

The drop time ball 1 is less than the drop time of ball 2. A further explanation is provided below.

Explanation:

The net force acting on the ball will be:

⇒ F_{net}=mg-F_r

Here,

F = Force

m = mass

g = acceleration

Now,

According to the Newton's 2nd law of motion, we get

⇒ F_{net} = ma

To find the value of "a", we have to substitute "F_{net}=ma" in the above equation,

⇒ ma=mg-F_r

⇒    a=g-\frac{F_r}{m}

We can see that, the acceleration is greater for the greater mass of less for the lesser mass. Thus the above is the appropriate solution.

What is the mass of a person running at 2.5 m/s with momentum of<br> 200 kg m/S
kondor19780726 [428]

Answer:

m = 80 kg

Explanation:

p = m × v

200 = m × 2.5

2.5m = 200

m = 200/2.5

m = 80 kg

The Zeeman effect, in which energy levels of electrons are shifted and produce a corresponding split in spectral lines observed,
blagie [28]

Answer:

Magnetic Field Strength

Explanation:

The effect of the splitting of the spectral lines of an atom into several of its components when a static magnetic field is present is referred to as Zeeman Effect.

The spectral lines here corresponds to the various discrete energy levels in the sun at which the emission and absorption of the different energy levels of the sun occurs.

The splitting of the spectral lines occurs due to the presence of the strong magnetic field on the surface of the sun.

Thus the Zeeman Effect is used to measure the magnetic field strength on the sun's surface.
