Answer:
the force of the plow pulling backward on the tractor
Explanation:
<span>Because P = W ÷ t, and W = F*t, you can substitute (W) for (F*t). Then substitute (F) for (m*a). This will leave you with P = (m*a*d)/t. Since you need velocity, youd want to solve for a so you can use v = a*t. a = (P*t)/(m*d) therefore, substituting a in v = a*t, v = (P*t*t)/(m*d)</span>
Answer:
C 2000v its obviously ans because if o is 1000 2 vo is 2000v
Answer:
the effects that a jet and the magnetic fields have on a ProStar Is :
Explanation:
over the years scientist have found out that magnetic fields and the Jets carry away angular momentum , which helps the ProStar grow more in size .
Answer:

Explanation:
Since
, we calculate the resistance rate by deriving this formula with respect to time:

Deriving what is left (remember that
):

So we have:

Which for our values is (the rate of <em>I(t)</em> is decreasing so we put a negative sign):
