A hiker climbs to the top of a mountain at rate of 0.5 m/hr. The speed of hiker is 1.3 x 10⁻⁴ m/s and the velocity of the hiker is 1.3 x 10⁻⁴ m/s west.
Speed is a scalar quantity. It is used to measure the distance traveled in a period of time. It is represented by -
s = d/Δt
where,
s = speed
d = distance
Δt = change in time
Velocity is a vector quantity. It is used to measure the change in position, that is, displacement over the change in time. It is represented by -
v = Δs / Δt
where,
v = velocity
Δs = change in position/displacement
Δt = change in time
The standard unit of velocity and speed both is m/s.

Hey there!:
Balanced Equation , for the reaction:
3 H₂SO₄(aq) + 2 Fe(s) → Fe₂(SO₄)₃(aq) + 3 H₂(g)
2 moles Fe ---------------------------------- 3 moles H₂
0.250 moles Fe ---------------------------- ( moles H₂ ) ??
____________________________________________
moles H₂ = 0.250 × 3 / 2
moles H₂ = 0.75 / 2
moles = 0.375 moles of H₂
Hope this helps!
The answer is D because there is no forces of attraction or repulsion between gas particles .
The answer is 4. It can hold 4 sublevels as s.p,d,f and it holds 32 electrons
