Hello~
Ice is harder than liquid water because<span> the molecules of ice are linked more tightly together than the molecules of liquid water.
Hope this helps! </span>
True. No matter can be created nor destroyed in pretty much every aspect of life, especially chemical reactions.
Given a = 10 cm/s²
u = 0 cm/s
v = 50 cm/s
we know that
v²=u²+2aS
2500=2×10×S
2500÷20 = S
S= 125 cm
The ramp is 125 cm
