When the electric field pierces outward through the section.
Answer:
15000 m/s
Explanation:
You just need to multiply the wavelength with the frequency.
Answer:
you divide the distance by the time it takes to travel that same distance, then you add your direction to it.
Answer: I have more time to think about the wonderful things in life that we don't always appreciate.
Explanation:
We can calculate the acceleration of Cole due to friction using Newton's second law of motion:

where

is the frictional force (with a negative sign, since the force acts against the direction of motion) and m=100 kg is the mass of Cole and the sled. By rearranging the equation, we find

Now we can use the following formula to calculate the distance covered by Cole and the sled before stopping:

where

is the final speed of the sled

is the initial speed

is the distance covered
By rearranging the equation, we find d:
