Answer: 2352 J

Explanation:

A body's<u> gravitational potential energy</u> U depends on its position and is mathematically expressed as follows:

U=mgh

Where:

m=60 kg is the mass of the skater

g=9.8 m/s^{2} is the acceleration due gravity

h=4 m is the skater's current height

Solving:

U=(60 kg)(9.8 m/s^{2})(4 m)

U=2352 J

The blackbody radation emmitted from a furnace peaks at a wavelength of 1.9 x 10^-6 m (0.0000019 m). what is the temperature ins
krek1111 [17]

Answer:

Temperature, T = 1542.10 K

Explanation:

It is given that,

The black body radiation emitted from a furnace peaks at a wavelength of, \lambda=1.9\times 10^{-6}\ m

We need to find the temperature inside the furnace. The relationship between the temperature and the wavelength is given by Wein's law i.e.

\lambda\propto \dfrac{1}{T}

or

\lambda=\dfrac{b}{T}

b = Wein's displacement constant

\lambda=\dfrac{2.93\times 10^{-3}}{T}

T=\dfrac{2.93\times 10^{-3}}{\lambda}

T=\dfrac{2.93\times 10^{-3}}{1.9\times 10^{-6}\ m}

T = 1542.10 K

So, the temperature inside the furnace is 1542.10 K. Hence, this is the required solution.

Equation InterpretationTwo Pizza Rolls are on the rotating carousel of a microwave oven. One is at the rim (edge) and the other
svetoff [14.1K]

Answer:

Explanation:

Both the pizza rolls are on two circular paths having different radii because one of them is on the rim and another is near the central axis. Their angular velocity are equal . That means they rotate by same angle in equal period of time. So in Δt they make equal angles at the centre. Hence their angular displacements are equal.

But length of arc made by them in equal interval of time that is Δt are different. Ir is so because their speed are different . Speed v and angular speed ω are related to each other as follows.

v = ω r .

So for objects in motion on circular paths having different radii , v are different even if their ω are same.

length of arc l = v Δt

So length of arc will be proportional to their v which will be proportional to r if their ω are same .

Hence length of arc will be proportional to radius of circular path,  ie their distance from the centre .
