A stream of doubly ionized particles (2 protons) moves at a velocity of 3.0 × 104 m/s perpendicularly to a magnetic field of 0.0
1 answer:
The force on a charged particle on a magnetic field is given by:
where B is the magnitude of the field, q is the charge of the particle, v is its velocity and θ is the angle between the field and the velocity of the particle.
In this case we have that:
• The magnitude of the field is 0.09 T.
,• The charge of the particle is 3.2 x 10 –19C .
,• The velocity is 3.0 × 10 4 m/s
,• The angle between the field and the velocity is 90°, since they are perpendicular.
Plugging these we have:
Therefore, the force on the charge is:

To solve the problem it is necessary to take into account the concepts related to energy efficiency in the engines, the work done, the heat input in the systems, the exchange and loss of heat in the soupy the radius between the work done the lost heat ( efficiency).
By definition the efficiency of the heat engine is
Where,
Temperature at the room
Temperature of the soup
The work done is defined as,
Where represents the input heat and at the same time is defined as
Where,
Specific Heat
The change at the work would be defined then as
On the other hand we have that the heat lost by the soup is equal to
The ratio between both would be,
Replacing with our values we have,
Therefore the fraction of heat lost by the soup that can be turned into useable work by the engine is 0.0613.
Answer:
Explanation:
As we know that there is no external torque on the system of platform, banana and the monkey
so the angular momentum of the system will remains conserved
so here we can say
here we know that
Now from above equation
