A) The calculated resistance needed to generate the current at low speed is; R = 480 ohms
B) Resistance at medium and larger speeds are;
At medium speed; R is less than that at low speed
At larger speed; R is less than that at medium speed.
A) We are given;
Voltage; V = 120 V
Current at lower speed; I = 0.25 A
Formula for resistance here is;
R = V/I
R = 120/0.25
R = 480 ohms
B) This means that if larger currents are required at higher speeds, it means that lower resistance would be required.
Similarly at medium currents the resistance will be lesser than that at lower speed but greater than that at larger speeds.

Explanation:
Answer:
a ship floats because of the mass and the parts of the ship help with staying on top of the water the buoyancy force is helpful for the ship to float which means weightless-airlessness and lightness.
Explanation:
The sum of n odd numbers n², where n is a natural number and represents the number of terms.
<h3>What is a natural number?</h3>
The numbers that we use when we are counting or ordering, which occurs commonly and obviously in nature.
Here, given all the odd numbers from 1,3,5,7..........999.
The sum of n odd numbers, n².
999² = 998001
Thus, the sum of all the odd numbers from 1 to 999 is 998001.
