Hydrogen bombs and stars both produce energy with nuclear _____.

Physics
1 answer:
Kruka [31]3 years ago
3 0

Answer;

- Nuclear fusion

Explanation;

-Hydrogen bombs and stars both produce energy with the nuclear fusion. On other side, the Sun and other stars make heat and light by nuclear reactions.

-The first stage of a hydrogen bomb involves a fission explosion which in turn leads to a nuclear fusion. The extreme heat and pressure from the initial atomic blast force together deuterium and tritium (two light gases made of hydrogen). When they are forced together, some of the hydrogen atoms fuse to one another, creating helium.

-This process of fusion releases even more energy per unit of mass than fission does, and the energy released from the fusion reaction also feeds back into the fission reaction, increasing its output.

what is the mechanical advantage of a crowbar when a worker uses 10N of force to pry open a window that has a resistance of 500N
Oksana_A [137]

Answer:

50

Explanation:

The mechanical advantage of a machine is given by

MA=\frac{F_{out}}{F_{in}}

where

F_{out} is the output force

F_{in} is the input force

For the crowbar in this problem,

F_{in}=10 N is the force in input applied by the worker

F_{out}=500 N is the force that the machine must apply in output to overcome the resistance of the window and to open it

Substituting into the equation, we find

MA=\frac{500}{10}=50

One violin creates a sound whose intensity level is 60dB. Find the intensity level of 16 violins, each playing at this intensity
Yanka [14]

Answer:

72.04 dB.

Explanation:

The intensity level of 60dB corresponds to the sound intensity I given by the equation

60dB = 10log(\dfrac{I}{I_0} )

where I_0 = 1*10^{-12}W/m^2

solving for I we get:

6 = log(\dfrac{I}{I_0} )

10^6 =\dfrac{I}{1*10^{-12}}

\boxed{I = 1*10^{-6} W/m^2}

Now, when 16 violins are playing the intensity I becomes

{I = 16(1*10^{-6} W/m^2)

which on the decibel scale gives

dB = 10log(\dfrac{16*10^{-6}}{1*10^{-12}} )

dB = 72.04\: dB.

Thus, playing 16 violins together gives the intensity level of 72 dB.
