Answer:
23.52092 J
Explanation:
m = Mass of block = 6.79 kg
s = Sliding distance = 2.82 m
= Angle of slide = 20.7°
= Coefficient of kinetic friction = 0.425
g = Acceleration due to gravity = 9.8 m/s²
Work done by the force of gravity is given by
The work done by the force of gravity is 23.52092 J
You draw a straight line from the start point to the end point. It doesn't matter what route was actually followed for the trip.
<span>The metric
system is the oldest name for the international system of units. The answer is <u>a.
True. </u>SI unit or the international systems of units are based on seven
basic units; the meter, kilogram, second, ampere, Kelvin, candela and mole. All
of these basic units are divided into multiples by a power of ten. For example
in meters, 1 meter is equal to: 1000 millimeter, 100 centimeter, 10 decimeter,
0.1 decameter, 0.01 hectometer, 0.001 kilometer and so on and so forth.</span>
