The power of a purely resistive lead is always positive although the current and voltage are sometimes negative. explain​

Physics
1 answer:
pickupchik [31]2 years ago
7 0

Answer:

Current is in phase with voltage in a resistive circuit. Note that the wave form for power is always positive, never negative for this resistive circuit. This means that power is always being dissipated by the resistive load, and never returned to the source as it is with reactive loads.Explanation:

A power plant supplies 1,100 megawatts of power to the electric grid. how many joules of energy does it supply each second?
slavikrds [6]
The answer is it will supply 1.1 x 10⁹ J of energy each second.
we can calculate this by using the following equation;
P = W/t 
<span>W = P x t 
</span><span>and by work energy relation;
E = W = P x t
</span>1 watt = 1j/s
1megawatt = 1000000 = 10⁶ j/s
<span>E = 1100 x 106 x 1 </span>
E = 1.1 x 10⁹ J

a object with a mass of 70 kilograms is supported at a height 8 meters above the ground.what's the potential energy of the objec
Agata [3.3K]
Potential Energy = mgh,

where m = mass in kg,  g ≈ 10 m/s², h = height above ground = 8 m

PE = mgh
  
      = 70*10*8 = 5600 J

Looking at the position of the house and the tree, if the man ran starting from the house going
Aleks04 [339]

Average velocity of man is 2 m/s

<u>Given that;</u>

Distance between tree and house = 16 m

Time taken = 8 seconds

<u>Find:</u>

Average<em> velocity</em>

<u>Computation:</u>

Average velocity = Total distance cover / Time taken

Average velocity = Distance between tree and house / Time taken

Average velocity = 16 / 8

Average velocity = 2 m/s
