Am i correct? If not then which one

cupoosta [38]

Answer:

Yes, it's correct

Explanation:

Newton's second Law states that the acceleration of an object is proportional to the net force applied on it, according to the equation:

$F=ma$

where

F is the net force on the object

m is the mass of the object

a is the acceleration of the object

We can re-arrange the previous equation in order to solve explicitely for a, the acceleration, and we find:

$F=ma\\\frac{F}{m}=\frac{ma}{m}\\\frac{F}{m}=a\\a=\frac{F}{m}$

So, we see that the acceleration is proportional to the net force and inversely proportional to the mass of the object.

Eva8 [605]

When she starts out, he is (40x2.5)= 100 miles ahead of her.

She gains (65-40)= 25 miles on him every hour.

It takes her (100/25)= 4 hours to catch up to him.

Janice has just measured the density of an object. Which value is possible? (Density: D = )

babunello [35]

It is 6 g/cm3 because density cannot be negative, and it is not speed in which the unit would be m/s.
