The correct answer to the question above is the third option; ultrasound imaging of the liver. The ultrasound imaging of the liver is definitely not an application of Doppler technology. If the Doppler technology is being used in medical field, it would be for the ultrasound of the heart and blood vessels for examination.
Answer:
Voltage is the measure of specific potential energy (potential energy per unit charge) between two locations. ... When a voltage source is connected to a circuit, the voltage will cause a uniform flow of charge carriers through that circuit called a current.
They need more oxygen to function, so gas exchange needs to increase
Answer:
piece of submerged iron
Explanation:
The buoyant force is given by:
where
is the density of the liquid (in this case, water)
is the submerged part of the object
g is the acceleration due to gravity
In this problem, the liquid used in the two examples is the same, water, so is the same; and g is the same as well. Therefore, the only difference between the two examples is .
For the piece of wood, we are told that the object is floating, so only a fraction of its total volume of 25.0 cm3 will be submerged: therefore the submerged volume will be less than 25.0 cm3. On the contrary, the problem tells us that the piece of iron is submerged, so the submerged volume in this case is 25.0 cm3. Therefore, the submerged volume for the iron is greater than for the piece of wood, so the buoyant force of the piece of iron is greater.
Answer
A
Explanation:
Weight = Mass x Acceleration due to gravity
Weight = 1000 x 9.81
= 9810 or 9.81x10^ 3
