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.
Answer:
It decreases
Explanation:
Wavelength and frequency has an inverse relationship. An inverse relationship is where one variable increases the other decreases and vice versa.
Answer: his total speed would be 3 seconds
Explanation: because if you mulimply 10 x 3 you get 30 meaning that your answer would be 3
Answer:
2.5 m/s²
Explanation:
Using the formula, v = u + at ( v = Final velocity; u = Initial velocity; t = Time; a = Acceleration)
25 = 0 + 10a
a = 25/10 = 2.5 m/s²
