Its just that the number of neutrons range from 0 to 2. (distance from 1 to 3 is 2)
Not totally sure about this one... I had it as a question in a 25 question test, and this was my answer. I got a 96% on that test, which means I only got one wrong, so this is probably right.
A printer has power of 100 W, and it takes time of 30 seconds to print out the document, then the power consumed in 30 seconds will be 0.8333 W.
The quantity of energy moved or changed per unit of time is termed as power in physics. The watt, or one joule per second, is the unit of power in the International System of Units. Power is also referred to as activity in historical texts. A scalar quantity is power.
Power is connected to other factors; for instance, the power required to move a land vehicle is equivalent to the sum of the vehicle's velocity, traction force on its wheels, and aerodynamic drag.
Assuming the printer consumes electrical energy at a steady rate, then:
100 ÷ 60 = 1.6667 watts per minute.
Now, calculate the power consumed in 30 seconds,
1.6667 ÷ 2 = 0.8333 watts.
Therefore, the power consumed in 30 seconds will be 0.8333 watts.

100W translates to 100 watts consumed in 1 hour. Assuming the printer consumes electrical energy at a steady rate, then: 100 ÷ 60 = 1.6667 watts per minute. 1.6667 ÷ 2 = 0.8333 watts consumed in 30 seconds.
Answer:
230
Explanation:
You do Ke = kinetic times distance divide by mass
c. Central Powers.
b. Allied Forces.
d. Axis Powers.
(b) 1
(c) 2
(d) 4
(e) 8
(f) None of them
Answer:
(c) 2
Explanation:
Heat transfer across the walls due to conduction is given by:
where,
q = heat transfer rate
K = thermal conductivity
A = Area
ΔT = change in temperature
L = thickness
For wall A:
For wall B:
Because the change of temperature and area of walls are the same. Dividing both terms:
using values given in the question:
Therefore, the correct answer is:
(c) 2
The addition of heat energy to a system always causes the temperature of that system to increase. This is always true because you are adding heat of a substance to increase its temperature. For example, you are going to drink a cup of coffee. And you wanted it hot to boost your attention. So you have to use hot water. In order for your water to become hot or warm, you need boil it in a kettle. Note that you are going to use an electric stove. The electric stove gets it energy from the source giving it a hotter temperature to the water in the kettle. You are applying heat energy to warm the water. So, the statement is true.
