Answer:
The five steps for determining density can be found in simple form as follows, measure the mass of the container, measure the volume of the liquid(s), measure the combined mass of the liquid and the container, and then determine the mass of the liquid alone and divide the mass by the volume of it.
Answer: not be able to stop in time to miss the object
Explanation:
The phrase "Over-driving your headlights" means that a person is driving at such a speed that the vehicle's stopping distance is greater than the maximum viewable distance with the headlights on.
When this occurs, it will be impossible for the vehicle to stop moving in time to avoid an object viewed by the driver in the range of his headlights.
This is a <u>dangerous driving practice</u> and can be avoided by driving at <u>reduced speeds</u>.
If the sound source is approaching you, the frequency you hear is higher than the real frequency of by the sound. How much higher depends on how fast the source is approaching. If the source's speed is constant, then the frequency you hear is constant ... higher, but not increasing.
FORMULA:
V = IR, where V = P.D ; I = Current; R = Resistance.
ANSWER:
Total Resistance(Req) in parallel circuit,
1/R = 1/R1 + 1/R2 + 1/R3
- 1/R = 1/40 + 1/20 + 1/10
- 1/R = 2 + 4 + 8/80
- 1/R = 14/80
- R = 80/14Ω
Now, I = V/R
- I = 60/80 × 14
- I = 21/2
- I = 10.5ampere.
