Answer:
The the speed of the car is 26.91 m/s.
Explanation:
Given that,
distance d = 88 m
Kinetic friction = 0.42
We need to calculate the the speed of the car
Using the work-energy principle
work done = change in kinetic energy
Put the value into the formula
Hence, The the speed of the car is 26.91 m/s.
The 2 seconds part isn’t relèvent to the question.
So momentum = mass x velocity
So 0.18 x 100 = 18
Answer:
C. valence electrons
Explanation:
Each dot is a valence electron.
Also, in my school, we called them Lewis Dot Structures.
The weather report never tells the "humidity" of the air. It tells the
"RELATIVE humidity". That's the percent of the moisture the air
COULD hold at the current temperature that it's actually holding
right now.
If the air is completely dry, then it's holding NONE of the moisture
that it COULD hold, and the relative humidity is zero percent.
