Answer:
No
Explanation:
walking requires friction because if friction did not exist we would slide around without stopping
Answer:

Explanation:
From the question, acceleration from
in 10 seconds.
Acceleration function can be written as:-

From the acceleration equation, we can obtain the velocity equation:

We calculate velocity after 10sec from the above v(t) as
.
To obtain distance travelled after 10 seconds:-

Therefore 200m is for 10seconds, and next 200m at 30m/s
Total time=
The best answer is b) <span>Method 1 and Method 3
Method 2, which is part of every other options, does involve using extra water because the dishwasher will necessarily use extra water, even if it is full when you use it.
On the other hand, fixing leaky faucets requires no extra water and the recycled water used to wash your car has already been used. </span>
<h2>Answer:</h2>
The refractive index is 1.66
<h2>Explanation:</h2>
The speed of light in a transparent medium is 0.6 times that of its speed in vacuum
.
Refractive index of medium = speed of light in vacuum / speed of light in medium
So
RI = 1/0.6 = 5/3 or 1.66
I would say B
Because technically if your just holding it your not doing anything
