Answer:
The magnitude of the acceleration of a proton at a distance of 1.5cm from the bead is 5.6 x10^13m/s².
The magnitude of the acceleration of a proton at a distance of 1.5cm from the bead is 9.8 x10^16m/s².
Explanation:
Newton's second law states that the total sum of the force acting on a particle in motion is equal to the mass of the particle times the acceleration due to the force. So the electric force between the bead and proton is equal to ma. That is,
Fe = kq1*q2/r² = m*a
The proton had a charge of +1.6x10^-19C and a mass of 1.67×10^-27kg
By substituting these values into the equivalent for a we have that the acceleration of the proton at a distance of 1.5cm form the bead is 5.6×10^13m/s²
The proton had a charge of -1.6x10^-19C and a mass of 9.10×10^-31kg
By substituting these values into the equivalent for a we have that the acceleration of the proton at a distance of 1.5cm form the bead is 9.8×10^16m/s²
The answer to your question is 12 degrees because you subtract 42 degrees minus 30 degrees to get 12 degrees
Answer:gravity and friction
Explanation:Gravity to keep yourself on the ground and friction to not slide when are walking.
Answer:
€0.98 per liter = 4.377 doller per gallon
Explanation:
It is given that, In Europe, gas cost approximately €0.98 per liter. We need to convert it into dollars($) per gallon.
We know that, 1 euro = 1.18 United States Dollar
1 litre = 0.264172 US gallon
Cost of gas in Europe is €0.98 per liter.
