And a 40N Torce in a southeriy direction? 4. A car works harder to accelerate from 0 to 10km/hr than it does to maintain a 10km/hr speed. Why is this? A. b/c
static friction is harder to overcome than kinetic or rolling friction. B. b/c static friction is easier to overcome than
kinetic or rolling friction. C. b/c static friction is harder to overcome than potential energy. D. b/c static friction is
easier to overcome than gravity.

C.

Explanation: because potential energy is the starting point before it moves. nothing has to be done.

it should be all of them because it asks if you included all of those in your answer

explanation:

each  column  of the  table  is called a group. elements in a group share similar properties. groups are  read  from  top  to  bottom. metal. metalloid. nonmetal. solid. liquid. gas. fe. hg. o.  2. 3. 4. 5. 6. 7. 8. 9.  2. beryllium. 9.012. 4.  sodium. 22.990.  11. 3.  magnesium. 24.305.  12.  potassium. 39.098.  19. 4.  calcium. 40.078.  20. i guess  i
