Explanation:
It is given that,
A nerve signal travels 150 meters per second. It is the speed of the nerve signal. We need to convert the number of kilometers that the nerve signal will travel in the same time.
We know that,
1 kilometer = 1000 meter
1 hour = 3600 seconds


So, the nerve signal will travel at the rate of 540 km/h. Hence, this is the required solution.
Answer:
14523.55J
Explanation:
The work done by the jogger against gravity is given by the following equation;

where m is the mass, g is acceleration due to gravity taken as
and h is the height of the hill.
Since the length of the hill is 132m and it is inclined at 12 degrees to the horizontal, the height is thus given as follows;

Substituting this into equation (1) with all other necessary parameters, we obtain the following;

For the most part aesthetics but you could argue they reduce air turbulence in some cases which would lead to better gas mileage. On sports cars however the goal is usually down force which is not wanted on economy cars as it can actually worsen gas mileage.
I hope that answered your question.
Answer:
Efficiency = 5%
Explanation:
Given that,
Supplies energy to the bulb = 100 J
Transferred energy by the bulb = 5 J
We need to find the efficiency of the bulb. It can be given by "

So, the efficiency of the bulb is 5%.
Its gotta be 7k bc that's what it adds up too
