Answer:
I = 5[amp]
Explanation:
Electrical power is defined as the product of voltage by current.
where:
P = power = 1150 [W]
V = voltage = 230 [V]
I = current [amp]
Now replacing:
![1150=230*I\\I=1150/230\\I=5[amp]](https://tex.z-dn.net/?f=1150%3D230%2AI%5C%5CI%3D1150%2F230%5C%5CI%3D5%5Bamp%5D)
A 15 [amp] fuse must be used. Always the fuse must be larger than the operating current, to protect the equipment from very high currents. above 15 [amp]
Answer:
C
Explanation:
Sound waves speed up noticeably when moving through a solid or liquid, because all it is is just particles colliding; and particles are way closer together with those states of matter.
The speed of light can change when moving through different substances, but this is dependent on complicated factors such as frequency, polarization, intensity, et. cetera
The important part is that it does change speed, so your answer is C.
Hope this helps!

The photography that shows a person using a type of wave technology, allows people to see very small objects clearly. D as it is a microscope
<h3>Why are wave technologies important?</h3>
Wave technologies are important because;
- They create waves that are more perfect than humans can provide by themselves.
- Certain inventions use waves to enhance human senses like hearing, sight and touch.
Thus, the photography that shows a person using a type of wave technology, allows people to see very small objects clearly. D as it is a microscope.
