Explanation:
Answer:Wrap more turns of wire around the nail.
Explanation:The power of an electromagnet is directly proportional to the amount of electricity passing through that electromagnet.
Now,if they increase the number of rounds of the copper coil,the electricity conducting surface amount will also increase.
And that's why the electricity passing through that electromagnet will increase along with the electromagnetic power of that electromagnet.
• Increasing the battery voltage :
If they increase the battery voltage,the electricity which is passing through that electromagnet will also increase in amount .
And as discussed previously,the increasing amount of electricity will also increase the electromagnetic abilities of the electromagnet.
Answer:
The y intercept of the H2 is greater than H1.
Explanation:
Given,
The height from which the first food packet dropped = 1681 feet
The height from which the second food packet dropped = 961 feet
To find :
Two height functions and to compare in graph?
solution:
is a vertical translation of 
The y-intercept of h2 is 720 ft less than that of h1.
is a vertical translation of 
.
The y-intercept of h2 is 10 ft greater than that of h1.
is a vertical translation of
The y-intercept of h2 is 720 ft greater than that of h1.
is a vertical translation of
.
The y-intercept of h2 is 10 ft less than that of h1.
