Answer:
Detecting kidney stones and cancer, visualizing fetus in the womb
Explanation:
Ultrasound technology can be used in detecting kidney stones and cancer throat and also visualizing a fetus in the womb. The use of ultrasound for detecting kidney stones started around 1961. Ultrasound has also been used in detecting various types of cancer including throat cancer. The use of ultrasound in knowing the gender of fetus in hospitals has been used for a long time. However, it's not used for cleaning dirty surgical tools. therefore, choice A, D and E apply.
- Detecting kidney stones
- Detecting throat cancer
- Visualizing a fetus in the womb
I=120 V/20 ohms
=6.0 A
SO the answer would be <span>A. 6.00 A</span>
Answer:
Speed = 300 m/s
Explanation:
Given the following data;
Frequency = 30 Hz
Wavelength = 10 m
To find the speed of the wave;
Mathematically, the speed of a wave is given by the formula:
Substituting into the formula, we have;
Speed = 300 m/s
Answer:
10 V
Explanation:
From Ohm's law, V=IR where V is the potential difference voltage, I is the current and R is resistance. Substituting 2A for current and 5 Ohms for resistance then V=2*5= 10 V
