Answer:
A police car's radar gun emits microwaves with frequency f. 1. =36 GHz. The beam ... waves at f. 2 . • Which frequency is higher, f. 1 or f. 2 ? • Calculate the difference f. 2. – f. 1 . 2. Page 3 ... The Doppler effect for EM waves is derived in ... velocity between source and observer. 4 ... The reflected waves have this shifted.
Explanation:
I enjoy stuff about guns so i hope this helps!
Cell differentiation is the process by which cells specialize to achieve their required functions. In order for a cell to differentiate, it will express specific genes. ... Importantly, mitosis produces cells that are identical to each other (clones).
Answer:
The correct option is (D). The value of cardiac output in the case of the human heart is approx. 5 liters in a minute. The multiplication product of heart rate and stroke volume gives the cardiac output.
Explanation:
The blood flow serves as the parameter for the calculation of cardiac output. For the restoration of homeostasis, increase or decrease in the cardiac output leads to the simultaneous increase and decrease in the blood flow and pressure respectively. Also, the reduction of cardiac output and venous return signifies the higher value of the tidal volume. The associated parameters namely stroke volume and heart rate is also affected by certain factors. Some of them includes age, gender, contractility, heart size and duration of contraction.
Besides the flow of blood in the body depends on the oxygen requirement of the target cell.
Answer:
A
Explanation:i beleive its a because it needs to be active
Each element absorbs light at specific wavelengths unique to that atom. When astronomers look at an object's spectrum, they can determine its composition based on these wavelengths. The most common method astronomers use to determine the composition of stars, planets, and other objects is spectroscopy.
