Friction- the external force that acts on objects and causes them to slow down when no other external force acts upon them.
The answer might be B because the value is negative, and negative could mean slowing down.
Answer:
d= 1.5 g/cm3
Explanation:
datos
m= 30g
v= 20cm3
d=?
formula
d= m / v
solución
d= 30g / 20cm3 = 1.5g/cm3
