The momentum of the rolling ball will have less momentum than before the collision and the stationary ball will have more momentum after the collusion.
40 miles/hour
Details:
after one hour they have traveled 40mi. So they have traveled 40mi. in 1hr, or 40mi/1hr or 40mi/hr.
the problem is about reading a graph. the graph says that they traveled 40 miles in the first hour
formula for average speed:
miles traveled/time it took=speed or d/t=r
<span>So are strong bases. The reason acids and bases conduct electricity is that when they are mixed with water, they "separate" into ions. And the ions are charge carriers. These charge carriers can be made to carry a charge (which is why that description fits them).</span>
Answer:
75ohms
Explanation:
V= IR
V = 1.5volts
I = 0.02A
1.5 = 0.02×R
Making R the subject
R = 1.5/0.02
R = 75ohms
The resistance in the circuit will be 75ohms
When two vectors are in same direction then we add up to get their resultant and in this case resultant would be maximum
R = A + B
R = 4 + 2
R = 6
If vectors are in opposite direction then they provide minimum resultant and in this case we subtract them
R = A - B
R = 4 - 2
R = 2
