Answer:
h=15.27m
Explanation:
Since at maximum height the vertical velocity must be null it's better to use the formula:
We will use this formula for the vertical direction, choosing the upward direction as the positive one, so we have:
or
which for our values is:
The correct option is C. i.e. <span>Using more coils of wire
</span>
Explanation:
The strength of an electromagnet can be increased in the following ways:
1. By increasing the number of coils.
2. By increasing the current/voltage
3. Using an iron core, increases the strength of the electromagnet.
Pressure and heat. I hope this helps
Answer:
ACTION REACTION FORCES
Explanation:
When there is an action frce there will be a reaction force
D)
Explanation:
Coz the position changes with time but the position change is not constant throughout time So, D) does not have constant velocity
