Explanation:
In a magnetic field, the radius of the charged particle is as follows.
r =
where, m = mass, v = velocity
q = charge, B = magnetic field
Therefore, q will be calculated as follows.
q =
=
=
=
= +2e
Thus, we can conclude that the charge of the ionized atom is +2e.
Answer:
Option A
250 degrees Celcius
Explanation:
If 1046J of heat energy is added to water, the water will experience a rise in temperature, at a rate that is directly proportional to its specific heat capacity.
Mathematically, this can be seen as
Where C = specific heat of water = 4.184 J/g • °C.
Q = heat energy = 1046 J
Therefore, the increase in temperature that will be experienced, is for 250 degrees Celcius
