Answer:
<u>As</u><u> </u><u>we</u><u> </u><u>kno</u><u>w</u><u> </u><u>that</u><u>,</u><u> </u>
- 1 mm/min = 1.66667E-5 m/s
- 1 m/s = 60000 mm/min
<u>Now</u><u>,</u><u> </u><u>come</u><u> </u><u>to</u><u> </u><u>the</u><u> </u><u>question</u><u> </u><u>-</u><u> </u>
Result : 2536 mm/min = 0.0422666667 m/s.
Answer:
a) 0 J
b) 0.92J
Explanation:
The work is defined as:
because the normal force is perpendicular to the displacement the work done for it is zero.
The force because of frictions has an angle of 180 degrees because it is opposite to the motion, so:
Answer:
Our estimate not done correctly because the width was unrealistic.
Explanation:
Given that,
Length = 6 m
Width = 0.5 m
We need to calculate the area of rectangular floor
Using formula of area
Where, l = length
w= width
Put the value into the formula
We need to find why this estimate not done correct
Using given data
We can say that,
We assume width was unrealistic.
The length of room is 6 m.
We know that,
So, the length would be 20 feet.
The width of room is 0.5 m.
The width of room would be 1.64 feet.
So, the area will be
Hence, Our estimate not done correctly because the width was unrealistic.
Sorry I had the answer but it wont let me type numbers :(.:
I reckon it would be centimetres (cm).
