Answer:
Number of turns per unit length will be 
Explanation:
We have given that strength of the magnetic field produced by the solenoid B = 7 T
Current in the solenoid i = 200 A
Let the number of turns per unit length is n
Magnetic field due to solenoid is given as 
here 
is permeability of free space n is number of turns per unit length and i is current
So 
need speed of sound on lhs
B student 2 because you add
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.
Answer:
27
Explanation:
It moves 13 meters in the first two seconds, backtracks 9 meters in the next 4 seconds, then moves forward 5 meters in the last 4 seconds. The total distance traveled is ...
13 m + 9 m + 5 m = 27 m
_____
In the first interval, the object moves from 1 m to 14 m away from the position reference, hence a move of 13 meters.
