So the answer is c because what is happening is called “beta decay”. A, gamma doesn’t change the two numbers. B, alpha increases it with a hydrogen atom. and D would make the bottom number on the left of the equation 9.

Identify the method of thermal energy transfer.
Solnce55 [7]

Answer:

A: Conduction

B: Convection

C: Radiation

Explanation:

Conduction is the transfer of heat in internal energy by microscopic collisions of particles and movement of electrons within a body so from the fire hitting the metal. Convection is the heat transfer due to the bulk movement of molecules within fluids such as gases and liquids so the water boiling in the pot. Radiation is the handle heating up due to the heat interacting with it.

OSCilloscope shows wave starts cycle minimum 20 units reaches max of 100 units before completing 5 milliseconds what is relation
Vitek1552 [10]

Answer:

T=0.02\ s

f=50\ Hz

Explanation:

Given:

  • minimum amplitude at the start of oscillation cycle, a_0=20\ unit
  • the first maximum amplitude after the start of oscillation cycle, a_{m1}=100\ units
  • Time taken to reach from the first minima to the first maxima, t=5\times 10^{-3}\ s

As we know that an oscilloscope executes a wave cycle represented by a sine wave. So we can deduce that it  has executed one-fourth of the cycle in going from the amplitude of 20 units to 100 units in 0.005 seconds.

<u>So the time taken to complete one cycle of the oscillation:</u>

T=4\times 0.005

T=0.02\ s is the time period of the oscillation

<u>We know frequency:</u>

f=\frac{1}{T}

f=\frac{1}{0.02}

f=50\ Hz
