Two protons are separated by a distance of 3.8 x 10−8 m in air. Find the magnitude of electric force and determine whether it is repulsive or attractive?

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h

happy to

pls mark as brainliest

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
