Answer:
the water level was shallow beach, then it rose to deep sea, then the water receded to a beach
Substance that can flow and take the shape of its container; either liquid or gas. friction. Force that opposes motion between two surfaces that are touching.
The equivalent resistance of the three resistors when connected in parallel is:
Since the three resistors in this problem are identical, we can call R their resistance, and we can rewrite the previous equation as
And since we know the value of the equivalent resistance,
, we can find the value of R:
Now the problem asks us what is the equivalent resistance of the three resistors when they are connected in series. In this case, the equivalent resistance is just the sum of the three resistances, so
Answer:
t = 1.68 min
S = 2.82 miles
Explanation:
Given,
The initial velocity of the vehicle, u = 0
The final velocity of the vehicle, v = 203 mph
The average acceleration of the vehicle, a = 2.93 ft/s²
= 7191.82 miles/h²
Using the first equation of motion
v = u + at
t = (v - u) / a
= (203 - 0) / 7191.82
= 0.028 h
= 100.8 s
Thus, the time taken by the vehicle to reach the final velocity is, t = 100.8 s
Using the third equations of motion
S = ut + 1/2 at²
Substituting the values
S = 0.5 x 7191.82 x (0.028)²
= 2.82 miles
Hence, the distance traveled by the vehicle, S = 2.82 miles
