The letter D represents the wavelength
This statement is
false.
The correct statement would be,
"W<span>hen you approach an
intersection and see a truck ahead signaling a right turn, you should stay
behind the truck,
away from the curbside, until the turn is completed."
Larger vehicles require a larger space to turn, being next to the truck and close to the curbside will only make it more difficult for the truck driver to complete the turn. This in turn will waste more time or even block traffic while the truck driver tries to complete the turn in the difficult situation that could have easily been avoided.</span>
The first thing you should do is calculate the work done when climbing the stairs. This work by definition will be given by:
W = F * d
W = (m * g) * (d)
W = ((71) * (9.8)) * (3) = 2087.4J
Then, you can calculate the power that in this case is given by
P = W / t
P = (2087.4) / (10) = 208.74W
To have the result in HP we use the fact that 1HP = 746W
P = (208.74) / (746)
P = 0.28 HP
answer
the power you produce in running up a flight of stairs is 0.28 HP
Speed is the rate of distance traveled per unit of time without regards to direction.
<u>Explanation</u>:
Speed is the pace of separation traveled per unit of time, regardless of direction.
Speed is straightforwardly relative to separate when time is consistent and conversely corresponding to a time when separation is steady. Multiplying one's speed would mean multiplying one's separation went in a given measure of time. Multiplying one's speed would likewise mean splitting the time required to travel a given separation.
Answer:
The given statement is false.
Explanation:
For any negative vector
The magnitude of the vector is given by
As we know that square root of any quantity cannot be negative thus we conclude that the right hand term in the above expression cannot be negative hence we conclude that magnitude of any vector cannot be negative.
