Answer:
64 kPa
Explanation:
The pressure exerted by a force on a surface is given by
where
p is the pressure
F is the force
A is the area on which the force is exerted
In this problem, let's call:
F = the weight of the performer, which is the force
A = the area of 1 stilt
At the beginning, the performer is standing on both stilts, so the area on which he exerts pressure is 2A. So the pressure is
(1)
Later, he stands on one stilt only. The force exerted is still the same (his weight), however, the area is now reduced to A; therefore, the new pressure is
which is twice the value calculated in (1); so, the new pressure is
Answer: not be able to stop in time to miss the object
Explanation:
The phrase "Over-driving your headlights" means that a person is driving at such a speed that the vehicle's stopping distance is greater than the maximum viewable distance with the headlights on.
When this occurs, it will be impossible for the vehicle to stop moving in time to avoid an object viewed by the driver in the range of his headlights.
This is a <u>dangerous driving practice</u> and can be avoided by driving at <u>reduced speeds</u>.
Answer:
BBbbb
Explanation:
B is the correct answer:))))
Answer:
Explanation:
(2.2500x10^3) x (3.00 x10^5)
First add the power values since all are to power 10 hence this will be 3+5=8
Then multiply the digit intergers ie 2.25*3=6.75
Therefore, in scientific notation this will be represented as
