35 electrons will be orbiting the nucleus.
Answer:
correct answers will be
2. The train is not an inertial frame of reference.
5.The train may be moving at a constant speed in a circle.
8. The train must be accelerating.
Explanation:
As we know that string makes an angle with the horizontal
so we can write the force equation for the given ball
also in Y direction
now we have
now we can conclude that train is accelerating with acceleration same as gravity
now correct answers will be
2. The train is not an inertial frame of reference.
5.The train may be moving at a constant speed in a circle.
8. The train must be accelerating.
Magnetic field lines always forms closed loop in such a way that it originates from North pole and then terminates back into the South pole
Inside the magnet we will draw the field lines from south pole to north pole
So it is not possible that magnetic field lines originates from north pole and again terminates at the same pole
So this is
FALSE
Answer:
The limits of our senses are
Limits of Sight
Our vision field of view is 120° sideways and 135° vertically
Angular visual resolution is about an 1/60 of one degree
The presence of blind spots in the eyes
Limits of sound
The hearing range is within 20 - 20,000 Hz and our threshold hearing above 0 to 5 decibel of sound
Limits of taste
We have very limited sense of taste which is partly dependent on our sense of smell with little objectivity in distinguishing tastes
Sense of smell
The establishing of the effectiveness of human sense of smell is gauged on numerous parameters with certain tests being inconsistent, as such, it is difficult to clearly establish the effectiveness of the human sense of smell
In comparison with the sense of smell of other living things such as dogs, the human sense organ is comparatively low
