Can u write it more specifically? so that I can answer
Total distance=60m+40m=100m
Total Time=6+4=10s
#a
![\boxed{\sf Speed=\dfrac{Distance}{Time}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Csf%20Speed%3D%5Cdfrac%7BDistance%7D%7BTime%7D%7D)
![\\ \sf\longmapsto Speed=\dfrac{100}{10}](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%20Speed%3D%5Cdfrac%7B100%7D%7B10%7D)
![\\ \sf\longmapsto 10m/s](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%2010m%2Fs)
#b
Displacement=AC=60m
![\\ \sf\longmapsto Velocity=\dfrac{Displacement}{Time}](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%20Velocity%3D%5Cdfrac%7BDisplacement%7D%7BTime%7D)
![\\ \sf\longmapsto Velocity=\dfrac{60}{10}](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%20Velocity%3D%5Cdfrac%7B60%7D%7B10%7D)
![\\ \sf\longmapsto 6m/s](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%206m%2Fs)
#C
![\\ \sf\longmapsto Velocity=\dfrac{60}{5}=12m/s](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%20Velocity%3D%5Cdfrac%7B60%7D%7B5%7D%3D12m%2Fs)
#d
The velocity of A to C is greater than Velocity from C to A
Answer : ![8.96 \frac{g}{cm^{3}}](https://tex.z-dn.net/?f=%208.96%20%5Cfrac%7Bg%7D%7Bcm%5E%7B3%7D%7D)
Explanation : To find density, we can use the formula as given below;
density ρ = ![\frac{mass(m)}{volume(v)}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bmass%28m%29%7D%7Bvolume%28v%29%7D%20)
Here, we have the mass as 89.6 g and the volume is
,
on calculating we get,
This means that the density of the copper sample is
Light bulb, automobile, & telephone.
Answer is: The ions in the solute separate from each other.
For example, dissociation of potassium iodide in water:
KI(aq) → K⁺(aq) + I⁻(aq).
Solvation is the interaction of solvent (water) with molecules or ions (in this example K⁺ and I⁻) in a solute.
Anion I⁻ has negative charge, so positive end (hydrogen atoms) of a water molecul attracts them.
