90 km/h is 25 m/s
the relative velocity when cars are traveling in opposite directions is the sum of the two
25+20= 45 m/s
Yes. Kinetic energy is a form of mechanical energy and friction will turn that kinetic energy into heat.
Answer:
11.98 N
Explanation:
Normal force = mg = 2.03 * 9.81
coeff of static friction must be overcome for the book to begin moving
.602 = F / (2.03 * 9.81) = 11.98 N
It is number 3 because I know it is
<span>ripple factor can be reduced by increasing the value of the load resistor (which means reducing the load of the circuit)</span>
