Byron bought a keyless entry door lock that has the digits 0 through 9 on the keypad. He wants to choose a three-digit entry code. How many different combinations are possible, if the digits can be repeated?
27
30
729
1,000

1000

Explanation:

There are 10 possible choices for the first number, 10 for the second, and 10 for the third. Multiplying all of this together, you get 10*10*10=1000 possible combinations. Hope this helps!

if the forces acting on an object are unbalanced, the object will accelerate in the direction of the net force on the object.

explanation:

this is best explained by having an understanding of newton's second law, which states that f=ma. you see, when the forces are unbalanced, net force (sum of all forces) is not zero. therefore making it necessary for the object to have an acceleration in the direction of the net force.
