Answer:
70509.8039216 N/C
Explanation:
k = Coulomb constant =
q = Charge = 2.00 µC
l = Length of filament = 5.1 m
r = Radius of cylinder = 10 cm
Electric field is given by
The electric field at the surface of the cylinder is 70509.8039216 N/C
Answer:
1) Time interval Blue Car Red Car
0 - 2 s Constant Velocity Increasing Velocity
2 - 3 s Constant Velocity Constant Velocity
3 - 5 s Constant Velocity Increasing Velocity
5 - 6 s Constant Velocity Decreasing Velocity
2) For Red and Blue car y₂ = 120 v = =
= 20 m/s
We get the same velocity for two cars because it is the average velocity of the car at the given interval of time. It is measured for initial and final position.
3) At t = 2s, the cars are the same position, and are moving at the same rate
Position - same
Velocity - same
The position-time graph shares the same spot for two cars.

We need to calculate the enthalpy change first:
Keep in mind this is the energy per mole, we need energy per atom:
We can see that this reaction needs the energy to get started (enthalpy change is positive).
The energy of a photon is given with this formula:
We need this photon to have the same energy (or higher) as our enthalpy change:
This wavelenght is clasified as near infrared.
