Answer:
Explanation:
Given that:
- moment of inertia of tucked body,
- rotational speed of the body,
- i.e.
- moment of inertia of the straightened body,
<u>Now using the law of conservation of angular momentum:</u>
angular momentum of tucked body=angular momentum of straight body
The velocity after 5 seconds is 50 m/s.
Answer:
Hertz extended Maxwell's idea that light is produced by the interaction of electromagnetic fields. Waves produced a diffraction pattern. Results supported the wave theory of light.
Cations are formed by losing electrons
Cations are basically positive ions
It's not lose or gain protons because atoms can't lose or gain protons. The protons don't move.
It's not gain electrons because electrons are negative. More electrons=more negative
If you can't remember cations are positive
CAT-ions are PAWS-itively charged
Answer : 
Explanation :
It is given that,
Charge, 
Velocity of Aircraft, 
(in west)
Magnetic field, 
( in north )
Using the relation as :
Magnetic force is ,
Using Right hand thumb rule, the direction of force is in the plane perpendicular to the velocity and the magnetic field i.e. 
.
