Newton's law of inertia says that an object at rest will stay at rest and an object in motion will stay in motion. The coffee was moving the same speed as the car and continued to do so even after the car itself had stopped.
Stop and look. always treat a railroad crossing with no lights or gates like a stop sign.
Answer:
maximum powr attained when resistor arrange in series and equal tp 143.86 w
Explanation:
WE HAVE FOUR CASES TO OBTAINED MAXIMUM POWER
we know that
Maximum current
I= 4.47 volt
case 1 - arrange in series
equivalent resistance [/tex]= 3R = 3*2.4 = 7.2 \ohm[/tex]
case 2 connected in parallel
power = 0.80* 4.47^2 = 15.98 w
case 3 two in series and one in parallel
case 4
one in series and two in parallel
The correct option is (A) <span>the first law of thermodynamics
Explanation:
The first law of thermodynamics takes the idea of law of conservation of energy and modify it for thermodynamics systems. It is the total internal energy of the systems equals to the amount of heat added "to" the system and the workdone "by" the system given as:
</span>ΔU = Q - W
<span>Q = heat added TO the system
W = work BY the system
</span>ΔU = Total internal energy
<span>
But the total internal energy is CONSERVED; it means that energy cannot be created or destroyed; it can only be transformed from one form to another. Hence the correct option is (A).</span>
