There are several differences between<span> a </span>physical and chemical change<span> in matter or substances. A </span>physical change<span> in a substance doesn't </span>change<span> what the substance is.

Answer:
0.4 m/s²
Explanation:
Given:
v₀ = 0.5 m/s
v = 2.5 m/s
t = 5 s
Find: a
v = at + v₀
2.5 m/s = a (5 s) + 0.5 m/s
a = 0.4 m/s²
The product of √30 and √610 is 10√183.
√30 = √(2×3×5)
and √610 = √(2×5×61
Since 61 can't be factorised further.
Therefore, the value of √30×√610 is
= √(2×3×5×2×5×61)
= 2×5×√(3×61)
=10√183
