Answer:
E = q V B describes the electric field induced
E Proportional to V B
while the magnet is pushed into the coil the induced field (B) will increase (consider 1 turn of the coil)
If V is constant the E-field will increase due to increasing B and the galvanometer will deflect accordingly
When V drops to zero the deflection must again be zero
So one would see a blip due to the deflection of the galvanometer
Note that as V increases the galvanometer will deflect one way and then as V drops to zero the deflection will be opposite (drop to zero when V is zero)
B always increases to a constant value because of the properties of the magnet.
Complete question:
If the swimmer could cross a 14 km channel maintaining the same average velocity as for the first 50 m in the pool, how long would it take?
For the first 50m in the pool, the average velocity was 2.08 m/s
Answer:
It would take for the swimmer approximately 1.87 hours.
Explanation:
If the swimmer maintains the average velocity on the channel, we should find and approximate value of the time it takes to cross the channel with the Galileo’s kinematic equation:
With x the displacement, v the average velocity and t the time, solving for t:
The electric force is small in comparison because charges are VERY small but the
gravitational force has to do with the mass of the Earth and Moon.
If a balloon is high up it will pop because pressure here think of it like this when you swim and go under water lets say 12ft you will notice that your head will hurt and it will take your oxygen away faster just like a balloon it has air in it so when it goes to high it will pop because its made of weak material so it will pop. and a low balloon because it will hit things and like i said balloons pop easy it could also get soft rubber because it is not moving and if like the sun was on it than it would pop as well i really hope this helped you
