Unit of weight is Newton(N)
Explanation:
first is gamma Ray's, last is d
Electrons that are the highest energy level is called Valence Electrons
Answer: 6.67 m/s
Explanation:
Recall that average speed is the total distance covered by a moving body divided by the total time taken. The SI unit is metres per second.
i.e Average speed = distance/time taken
Given that:
Distance covered = 6.00 km
Convert kilometers to meters
If 1 km = 1000 m
6.00 km = (6.00 x 1000) = 6000m
Time taken to school = 0.250 hours
Convert time in hours to seconds
If 1 hour = 60 minutes & 1 minute = 60 seconds
Then, 0.250 hours = (0.250 x 60 x 60)
= 900 seconds
Average speed = ?
Average speed = 6000m/900s
= 6.67 m/s
Thus, your average speed to school is 6.67 m/s
