Answer: part 1 is mass and part 2 is density
Explanation: I just did it and got it right
<span>ripple factor can be reduced by increasing the value of the load resistor (which means reducing the load of the circuit)</span>
Answer:
P=F/A where F is the weight of the water and A is the area on which it is resting. The weight of the water is mg. The mass of the water is dv where d is the density and v is the volume. Finally, the volume of the water in a vessel is equal to the area of the base of the vessel times the height of the vessel. (v=Ah)
Plugging everything in we get:
P = dAhg/A
So
P=dhg
So we have shown that liquid pressure is directly proportional to height of liquid in a vessel.
Answer:
The dolphin's speed is 17 mi/h
Explanation:
Use the formula for average velocity: Distance/time
then the average speed of the dolphin is 51/3 mi/h = 17 mi/h
A reference point would be something not on the ship which could be used to calculate distance traveled.
Answer: C.) A lighthouse on a nearby Island
