Answer:
400 N
Explanation:
Change of Kinetic Energy to Friction Wok
∆KE = W
½ x m x (v(5)² - v(3)²) = f x d
½ x 500 x (5² - 3²) = f x 10
250 x (25 - 9) = f x 10
25 x 16 = f
f = 400 N
Answer:
metals like iron or nickel
Explanation:
Resistance can be caused by specific resistance tools, like resistors, or loads (the part of the component that uses the electricity) like a light bulb or a speaker. Resistance is measured in ohms and can be measured by a multimeter.
Since Jason plays a lot of sports <em>(D)</em>, there's a good chance that he has developed a greater-than-average lung capacity. This is a good thing.
Speed=Distance/Time
Distance=40m,time=5.79seconds
S=40/5.79
=6.908m/s
