Answer:
1788.402 MJ
Explanation:
Work done = Force (N) x distance (m)
First we have to convert distance into metres:
173.8 x 1000 = 173,800 m
Then plug these values into the equation above:
173,800 x 10290 = 1788402000 J
The reason it's Joules (the unit for energy) is because work done = energy transferred
Now we have to convert Joules into Mega Joules:
1 J = 1/1000000 MJ
1788402000 J = 1788402000/ 1000000 = 1788.402 MJ
nucleosynthesis is the process in nuclear reaction
Answer:
Bulbs are filled with chemically inactive Nitrogen or Argon gas to prevent the oxidation of tungsten filament used in the bulb. A bulb is filled with an inert gas such as argon or nitrogen slows down the evaporation of the tungsten filament compared to operating it in a vacuum.
Explanation:
Answer:
Resistance 2.
Explanation:
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
Where;
- V represents voltage measured in voltage.
- I represents current measured in amperes.
- R represents resistance measured in ohms.
<u>Note</u>: Voltage is the same as potential difference.
Given the following data;
Resistance 1 = 10 Ohms
Current 1 = 3 Amperes
Potential difference 1 = current * resistance
Potential difference 1 = 3 * 10
<em>Potential difference 1 = 30 V</em>
To find the potential difference in 2;
Resistance 2 = 5 Ohms
Current 2 = 10 Amperes
Potential difference 2 = 10 * 5
<em>Potential difference 2 = 50 V</em>
Therefore, Resistance 2 has greater potential difference.
The solution to your problem is as follows:
a=dv/dt=2*0.82*twhat time velocity is 13.7 solve 13.7=0.82*t^2 t=sqrt(13.7/0.82) =4.51 sUse the time in the acceleration expression a= 2*0.82*4.51=7.39m/s^2
