In which scenario does radiation occur?

Physics

Pretty sure a, because it’s a stove and it uses electricity like almost a normal appliance for the kitchen would, the rest are just a natural force without any radiation to occur in them, electricity is the same as technology and believe it or not technology like phones give off radiation, so yeah. hope this was helpful!

What distance does electromagnetic radiation travel in 55.0 μs ?
Komok [63]
Electromagnetic radiation is an energy that is known as light. so electromagnetic radiation will have the same speed as the speed of light which is 3 x 10^8 m/s. so the distance it travel at 55 x 10^-6 s is:
D = ( 3 x 10^8 m/s ) (  55 x 10^-6 s )
D = 16500 m

determine the amount of potential energy of a 5.0-N book that is moved to three different shelves on a bookcase . the height of
klasskru [66]
Potential energy<span> is the </span>energy<span> that is stored in an object due to its position relative to some zero position. It is calculated by the expression PE = mgh where mg is the weight of the book and h is the height. It is calculated as follows:

PE = 50(1) = 50 J
</span>PE = 50(1.5) = 75 J
PE = 50(2) = 100 J

Three monkeys A, B, and C weighing 20, 26, and 25 lb, respectively, are climbing up and down the rope suspended from D. At the i
Marina86 [1]

Answer:2235.2lb-ft/s^2

Explanation:

Given

Mass of monkey A=20lb

Mass of monkey B=26lb

Mass of monkey C=25lb

acceleration of monkey A=4.2ft/s^2

acceleration of monkey B=0

acceleration of monkey C=-5.4ft/s^2

Force Due to monkey A\left ( F_A\right )=20\times 4.2 =84lb-ft/s^2\left ( downwards\right )

Force Due to monkey A\left ( F_B\right )=26\times 0 =0lb-ft/s^2

Force Due to monkey A\left ( F_C\right )=25\times 5.4 =135 lb-ft/s^2\left ( upward\right )

In addition to it  Weights of monkeys will be acting downwards therefore net Downwards force is balanced by tension

T=\left ( 20+26+25\right )32.2+84-135=2235.2 lb-ft/s^2

Two metal plates 15mm apart have a potential difference of 750v between them. The force on a small charged sphere placed between
Romashka [77]

Answer:

50,000 V/m

Explanation:

The electric field between two charged metal plates is uniform.

The relationship between potential difference and electric field strength for a uniform field is given by the equation

\Delta V=Ed

where

\Delta V is the potential difference

E is the magnitude of the electric field

d is the  distance between the plates

In this problem, we have:

\Delta V=750 V is the potential difference between the plates

d = 15 mm = 0.015 m is the distance between the plates

Therefore, rearranging the equation we find the strength of the electric field:

E=\frac{\Delta V}{d}=\frac{750}{0.015}=50,000 V/m

If 2050 J of heat are added to a 150 g object its temperature increases by 15°C.
Darina [25.2K]

When an object gets heated by a temperature ΔT energy needed, E = mcΔT

Here energy is given E = 2050 J

Mass of object = 150 g

Change in temperature ΔT  = 15 ^0C = 15 K

a) Heat capacity of an object equal to the ratio of the heat added to (or removed from) an object to the resulting temperature change.

  So heat capacity = E/ΔT = 2050/15 = 136.67 J/K

b) We have E = mcΔT

                    c = \frac{2050}{150*10^{-3}*15}  = 911.11 J/kgK

 So object's specific heat = 911.11 J/kgK
