Answer:
A. <u>The water decreases the friction between the floor and the feet </u>
Explanation: Think about it like this, when your in the shower and water is on your skin, you can scrub it fluidly, but when the water dries in your towel, there is more friction when your rub your skin, this is because the molecules in water aren't as compact as solids, so anything acting against it, is most likely to disperse from it.
Answer:
Increases is the correct answer.
Explanation:
Just took the quiz.
I have no Idea it might be 5cm squared
1) Displacement: -49 m, in the negative direction
Explanation:
The displacement of an object is a vector, whose magnitude is given by the difference between the final point of the motion and the starting point:
In this problem, the starting point is +34 m, while the final position is -15 m; therefore, the displacement is:
and the direction is negative, in according to the negative sign.
2) Velocity: -3.27 m/s
Explanation:
Velocity is equal to the ratio between the displacement and the time taken:
in this problem, we have:
d = -49 m is the displacement
t = 15 s is the time
therefore, the velocity is
and the direction is negative.
Answer:
1Kilowatt =1000watts
Now
Energy =Power x time
We need our power in Kilowatt and Our time in hours
Given
Power = 1200Watt
Divide this by 1000... To get its value in Kilowatt
Power = 1.2kilowatt
Time=6min
Divide by 60 to get its value in hours
Time = 6/60hr = 0.1hrs
Energy = 1.2kilowatt x 0.1hrs
=0.12kilowatt hours
