Answer:

The stronger person holds it closer to them.

Explanation:

if the stronger person were to hold the ladder closer to them, they would be holding more of the weight thus making the weaker person have less weight. this is because of the center of gravity being closer to the stronger person.

Answer:

Strong person should hold the ladder near the center while weak person should hold it at the end

Explanation:

So here we can see from the figure that in order to hold the ladder straight the two forces must counter balance the weight of the ladder

So here we know that

mg = F_1 + F_2

also for torque balance of the ladder we know that

F_1 r_1 = F_2 r_2

here we know that the distance of force F1 is less than that of other force F2 so

\frac{r_1}{r_2} < 1

so we can say that

\frac{F_2}{F_1} < 1

so weak person will apply less force if he hold it at the long distance

How many neutrons does element X have if it’s atomic number is 28 and it’s mass number is 81?
labwork [276]

Well let’s put it this way. To find the neutrons you subtract the atomic atomic Nuremberg from the atomic mass. So

Mass=81-Number=28

81-28=53

Final answer is 53.

How much power does an electric device use if the current is 36.0 amps and the resistance is 3.9 ohms?
dsp73
<span>Question: How much power does an electric device use if the current is 36.0 amps and the resistance is 3.9 ohms? </span>

How?: 

Equation: P = I^2 R          

Meanings:
P = Power in Watts
I = Current in Ampere
R = Resistance in ohms.

Plugged in: P = 36^2<span> x 3.9 = 5054.4
 
Answer: P= </span>5100 watts.

A Nichrome wire 44 cm long and 0.30 mm in diameter is connected to a 3.1 V flashlight battery. What is the electric field inside
Alexeev081 [22]

Answer:

7.05 Volts/m

Explanation:

L = length of the Nichrome wire = 44 cm = 0.44 m

V = Potential difference across the end of the wire = battery voltage = 3.1 Volts

E = magnitude of electric field inside the wire

Magnitude of electric field inside the wire is given as

E = \frac{V}{L}

Inserting the values

E = \frac{3.1}{0.44}

E = 7.05 Volts/m

Which vehicle has the LEAST kinetic energy? 18-wheeler, minivan, car, or bike?
Whitepunk [10]

We can make pretty good guesses for their masses, but kinetic energy also depends on their speeds, which we don't know, and may change.

As an example ... If the truck, the van, the car, and the bike are all parked at the mall, then a scampering mouse has more kinetic energy than all of them combined.

As the question stands, no answer is possible.
