Distance = 400 m, Displacement = 400 m in the direction of the straight line.
Answer:
The power dissipated if the three resistors were connected in parallel across the same potential difference is 405 W
Explanation:
Given;
three identical resistors connected in series
let the first resistor = R₁
let the second resistor = R₂
let the third resistor = R₃
Rt = R₁ + R₂ + R₃
Since the resistors are identical, thus, R₁ = R₂ = R₃ = R
Rt = 3R
Power is given as;
P = IV = V² / R
If the 3 identical resistor connection were changed to parallel, then the equivalent resistance in the circuit will be;
Therefore, the power dissipated if the three resistors were connected in parallel across the same potential difference is 405 W
<u>Answer:</u>
<em>The amount of water entering the earth through precipitation is equal to the amount of water leaving earth through transpiration.</em>
<u>Explanation:</u>
Rates of precipitation and evaporation vary widely according to regions and seasons. But in a global scale the rates are equal. Thus the total amount of earth’s water maintains its constancy even though there is a continuous change in forms of water.
Evaporation and transpiration are the forms in which Water leaves the earth and it returns to the earth in various forms of precipitation like rain, snow, dew, fog etc. This water then reaches ocean and land. The water that reaches the land flows as surface run off into rivers and water bodies or seep into the ground replenishing the ground water table.
Solution:
initial sphere mvr = final sphere mvr + Iω
where I = mL²/3 = 2.3g * (2m)² / 3 = 3.07 kg·m²
0.25kg * (12.5 + 9.5)m/s * (4/5)2m = 3.07 kg·m² * ω
where: ω = 2.87 rad/s
So for the rod, initial E = KE = ½Iω² = ½ * 3.07kg·m² * (2.87rad/s)²
E = 12.64 J becomes PE = mgh, so
12.64 J = 2.3 kg * 9.8m/s² * h
h = 0.29 m
h = L(1 - cosΘ) → where here L is the distance to the CM
0.03m = 1m(1 - cosΘ) = 1m - 1m*cosΘ
Θ = arccos((1-0.29)/1) = 44.77 º
