Answer:
Explanation:
Given
mass of sled =26 kg
coefficient of static friction 
coefficient of kinetic friction 
In order to move sled from rest we need to provide a force greater than static friction which is given by

After Moving Sled kinetic friction comes in to play which is less than static friction

therefore minimum force to keep moving sledge at constant velocity is 18.34 N
Answer:
The solution is neither acidic or basic,
PH < 7 acidic
PH = 7 neutral
PH > 7 basic
It is a measure of the (H+) hydronium concentration.
Answer:
I'm pretty sure it means like getting abs and working out your stomach.
Explanation:
Answer:
all scenarios are using the same power
Explanation:
we know that power is defined as P(Watts)=W(Joules)/t(seconds).
When applying this formula to each of the scenarios we find:
