Yes, yes, we know all of that. It certainly took you long enough to
get around to asking your question.
If
a = (14, 10.5, 0)
and
b = (4.62, 9.45, 0) ,
then, to begin with, neither vector has a z-component, and they
both lie in the x-y plane.
Their dot-product a · b = (14 x 4.62) + (10.5 x 9.45) =
(64.68) + (99.225) = 163.905 (scalar)
I feel I earned your generous 5 points just reading your treatise and
finding your question (in the last line). I shall cherish every one of them.
It’s easier to lift the wheelbarrow when the load is near the front because there isn’t any pressure near the back where the handles are.
Answer:
"0.758315 sec" is the appropriate choice.
Explanation:
The given values are:
Angular speed,

or,
= 
Tire rotates,
= 3.5 times
Now,
The time interval will be:
⇒ 
⇒ 
⇒ 
⇒ 
Answer:0.45ohms
Explanation:
Let R be there equivalent resistance
1/R=1/r+1/r+1/r
1/R=1/5+1/1+1/1
1/R=1/5+2
1/R=(1+10)/5
1/R=11/5
Cross multiplying we get
11R=5
Divide both sides by 11
11R ➗ 11=5 ➗ 11
R=0.45ohms
