Answer:
a) least mass
Explanation:
According to the Newton's first law of motion, more the mass of a body the greater is its inertia, and inertia is the tendency of a body to resist any change to its state of rest or uniform motion.
Greater is the mass of charge least is its deflection under the influence of magnetic field.
<em>This can be explained well by the mathematical equations relating the </em><em>centripetal force and the magnetic force</em><em> on a charged mass moving in a magnetic field perpendicular to the velocity:</em>
where:
m = mass of the charged particle
v = velocity of projection of the charged mass into the magnetic field
r = radius of curvature of path of charged mass under the magnetic force
q = magnitude of charge on the particle of mass 'm'
B = intensity of magnetic field normal to 'v'
i.e.
- Speed of the charge is higher when its mass is lesser and according to the Fleming's left hand rule we known that the charge continuously faces a magnetic force while moving in the field.
& also,
- Which indicates that more is the mass of charge larger is the radius of its trajectory of motion which means lesser is its deviation.
None of the diagrams you attached shows the scenario accurately,
or at all.
Heat flows from Object-B to Object-A, until both objects are at
the same temperature, somewhere between 10°C and 29°C.
The 'North pole' of any magnet is the one that would be attracted to the Earth's North magnetic pole. In that sense, they are just labels that identify the opposite magnetic force produced at each end of the magnet. The Earth'smagnetic field also has poles, North and South. more at study.com
Answer:
Radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heated object. ... The energy lost is emitted as light or electromagnetic radiation. Energy that is absorbed by an atom causes its electrons to "jump" up to higher energy levels. All objects absorb and emit radiation.

Answer:
the change in energy of the block due to friction is
Explanation:
From the question we are told that
The frictional force is
The mass of the block is
The length of the ramp is
The height of the block is
The change in energy of the block due to friction is mathematically represented as
The negative sign is to show that the frictional force is acting against the direction of the block movement
Now substituting values
