A 12 Volt lead-acid car battery, engineered for "up to 500 or more charge/discharge cycles," has a rating of 95.0 Ampere-hours.

It sells for $ 126.00. If initially fully charged, what is the total electrical energy that the battery can deliver before it needs to be recharged?

Answer:

Explanation:

Electrical energy = potential x charge

potential = 12V ,

Charge = 95 amp-hours

= 95 x 60 x 60 coulomb

= 342000 coulomb

Electrical energy stored in battery  = 342000 x 12

= 4104000 J

= 4.1 x 10⁶ J .

How long does it take to walk 0.13 miles
LekaFEV [45]
<span>0.13 miles are equal to 209 meters or 228.8 yards and the human walking speed is about 3.1 miles per hour, with all those calculations we can say that every 0.05 miles would take an average person about 1 minute, and if we add 0.10 + 0.03 it would be about 4-5 minutes to travel that short distance.</span>

State newton's universal law of gravitation
Lorico [155]

Every particle of mass is attracted to every other particle of mass.  The magnitude of the force between two objects is proportional to the product of their masses, and inversely proportional to the square of the distance between them.  The direction of the force is along the line between their centers.

(NOTE:  Newton's 3rd law of motion tells us that gravitational forces always come in pairs.  Between two objects, there are two forces ... one in each direction.  Their strengths are equal ... Your weight on Earth is exactly equal to the Earth's weight on YOU.)

Two devices with capacitances of 25 μf and 5.0 μf are each charged with separate 120 v power supplies. calculate the total energ
mash [69]
The energy stored in a capacitor is given by
U= \frac{1}{2} CV^2
where C is the value of the capacitance while V is the voltage difference applied to the capacitor.

Let's calculate the energy of the first capacitor:
U_1 =  \frac{1}{2} (25\cdot 10^{-6}F)(120 V)=1.5 \cdot 10^{-3}J

And now the energy of the second capacitor:
U_2 =  \frac{1}{2} (5 \cdot 10^{-6}F)(120 V)=3 \cdot 10^{-4}J

So, the total energy stored in the two capacitors is
U=U_1 +U_2 = 1.8 \cdot 10^{-3}J

a car dealer sells 4 makes of cars in 5 colors with either standard or automatic transmissions. how many variations does the dea
Anuta_ua [19.1K]

<u>The number of variations the dealership have is 40 cars</u>.

Data given;

  • The number of different product = 4
  • The number of transmission = 2 (standard or automatic)
  • The numbers of colors available = 5

<h3>Dealership variation </h3>

This is the total numbers of cars available in the dealer shop at the moment.

To get that, we simply multiply the numbers of colors available, the number of transmission and the makes of car available.

This is equal to

4*2*5=40

From the above calculation, we can say that <u>the variations the dealership offers is 40</u>
