Basically, it sends out a signal that is the same frequency as your phone. This signal is powerful enough to outmuscle your phone's signal.
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
Answer:
FLASH FLOODS CAN CAUSE VEHICLES TO FLOAT AND FILL WITH WATER, TRAPPING AND DROWNING PEOPLE. WHILE ESPECIALLY DANGEROUS AT NIGHT AND IN DEEP WATER, EVEN ____ INCHES OF WATER CAN FLOAT SOME SMALL CARS.
The Answer is SIX Inches.
Explanation:
Flash floods: are short-term events and are associated with short, high-intensity rainfall which occur when creeks that are normally dry fill up and other creeks overflow. Densely populated areas have a high risk of flash floods. Water levels in flash floods can rise one foot in five minutes making Six inches of water able to reach the bottom of most passenger cars. Moving water will exert pressure on a car. The car floats downstream when stream force exceeds the friction force, the car will be carried when bouyancy force (which is the upward force exerted by any fluid upon a body placed in it) is greater than vehicle weight.
I posted this because I got it correct. The answer is 28J.
Answer:
he kinetic energy increases on the descent, being maximum at the lowest point of the trajectory.
Explanation:
In these semicircular sections the skaters slide from one side to the other, in the downward path their kinetic energy increases and their potential energy decreases; When it leaves the ramp and is in the air, the kinetic energy decreases rapidly, up to the point of maximum height where the kinetic energy is zero.
Consequently, the kinetic energy increases on the descent, being maximum at the lowest point of the trajectory.
