True.
It has been studied in a research study that claims birds have the ability and capability to regenerate their hair cells.
Brainliest please?
Because field lines don’t all go in to the pole. The bottom half go outwards not inwards.
Answer:
D
Explanation:
D) The overall work done by gravity is zero
This statement is correct .
If m be the mass of each of the children and h be the height of tower
work done by gravity on the boys in going up = - mgh
it is so because force applied by gravity = mg downwards and displacement
is upwards
work done will be negative = - mgh
Work done by gravity on boys when they come down = + mgh because both force and displacement are downwards .
Hence total work done = - mgh + mgh = 0.
The children will have same kinetic energy as the inclined surface is friction-less so no energy will be dissipated hence addition of energy to boys in both the cases will be same.
Answer:
it should be 8,000
Explanation:
because if you multiply the mass value by 1000, you will get 8,000

Answer:
I would strongly recommend Exploring Quantum Physics through Hands-on Projects for physics practicals.
Explanation:
- Though it is not about books, but it is solely on you how you want to get knowledge. If you are truly passionate about learning physics in a practical way "Exploring Quantum Physics through Hands-on Projects" will be the best one out there.
- Besides "Laboratory Projects in Physics, a Manual of Practical Experiments for Beginners" is also a promising one.
- There are detailed chapters on important topics like light as a wave and particles, atoms and radioactivity, Schrödinger, etc.
- If you wisely follow these books, you will surely get all your doubts cleared and learn new mechanisms easily.
