Answer:
60km/hr due east
Explanation:
Given parameters:
Displacement = 60km East
Start time = 10am
End time = 11am
Unknown:
Average velocity = ?
Solution:
The average velocity is the displacement divided by the time taken.
For this journey, the time taken is;
11am - 10am = 1hr
So;
Average velocity =
= 60km/hr due east
A) true; he performed experiments which showed that negatively-charged electrons orbited the positively-charged nucleus.
Answer:
4.5
Explanation:
volume is length x breath x height
since 75 is in cm, we convert it to metre
= 0.75m
= 1.2m x 5m x 0.75m
=
