Explanation:
When a charged particle describes a circular path in a uniform magnetic field, the charged particle experiences a magnetic force towards the center of circular path, according to Fleming's left hand rule. Therefore the magnetic force and velocity (tangent to circular path) are perpendicular to each other during the circular motion. As the direction of displacement, is the direction of velocity, hence force and displacement are perpendicular to each other.
Therefore work done by magnetic force,
W=Fscos90=0
Answer:
3.176hours
Explanation:
270/85=3.126 hours DISTANCE / SPEED = TIME
It is FALSE.
The absolute value of both numbers is 7, therefore they are equal!
Hope this helps!
To solve this problem, apply the concepts related to the calculation of the work performed according to the temperature change (in an ideal Carnot cycle), for which you have to:
Where,
C = Heat capacity of the Brick
= Cold Temperature
= Hot Temperature
Integrating,
Our values are given as
Replacing,
Therefore the work perfomed by this ideal carnot engine is 58kJ
