The distance between the two cities is 513.24 km.
The time spent on the journey when the two trains meet is calculated as follows;
(Va - Vb)t = d
where;
(76 - 65)t = 40
11t = 40
t = 40/11
t = 3.64 hr
d1 = 76 km/h x 3.64 h
d1 = 276.64 km
d2 = 65 km/h x 3.64 h
d2 = 236.6 km
The distance between the two cities = 276.64 km + 236.6 km
= 513.24 km

Answer:
diffusion is the answer.
height is 45 metres
Explanation:
KE=PE
¹/²mv² = mgh
¹/²v² = gh
but v =30m/s
(30)² / 2 =10h
450=10h
h = 45m
one of the graph is postion-time graph while the other one is velocity-time graph
No. An atom is made up of 3 kinds of particles, protons, neutrons, and electrons. Protons and neutrons make up the center of the atom.
