Answer:
e, Relay
Explanation:
When short circuit or serious overload current occurs in the circuit,,the electromagnet generates enough suction to cut off the power supply.
Ammonia, Bananas, Bleach,
Tomatoes, Baking Soda are all examples of a base.
Answer:
F1 = 80
Explanation:
f1= f2 √ (F1/F2)
Where f1 = 300, f2 = 260 and F2 = 60
Putting in the above formula
300 = 260√(F1/60)
Dividing both sides by 260
=> 1.15 = √(F1/60)
Squaring both sides
=> 1.33 = F1/60
Multiplying both sides by 60
=> F1 = 80
Answer:
b. speed of a wave
Explanation:
The speed of a wave is defined as the product between the wave's frequency and the wave's wavelength:

where
is the wavelength of the wave
f is the frequency
Therefore, we see that this matches the definition listed in choice B:
b. speed of the wave.
The other options are:
a. number of waves passing a point in a second. --> frequency
c. distance between wave crests. --> wavelength
d. time for one full wave to pass. --> period
