Answer:
3.6m
Explanation:
if you are at a building that is 46m above the ground, and the professor is 1.80m, the egg must fall:
46m - 1.80m = 44.2m
the egg must fall for 44.2m to land on the head of the professor.
Now, how many time this takes?
we have to use the following free fall equation:
where 
is the height, 
is the initial velocity, in this case 
. 
is the acceleration of gravity: 
and 
is time, thus:
clearing for time:
we know that the egg has to fall for 44.2m, so 
, and , so we the time is:
Finally, if the professor has a speed of 
, it has to be at a distance:
and t=3.002s:
so the answer is the professor has to be 3.6m far from the building when you release the egg
Answer:
0.45 miles
Explanation:
since, car will be running on the edge of track, distance covered in one lap by car will be equal to circumference of track.\
we will use value of pi as 22/7
Circumference for any circular shape is given by 
Hence, in one lap distance will be covered
in 7 laps 
distance will be covered.
but is given that 7 laps should be equal to 10 miles
so 10 miles will be equal to 
Thus, diameter of track will be 0.45 miles to meet the requirement.
Resistance can be caused by specific resistance tools, like resistors, or loads (the part of the component that uses the electricity) like a light bulb or a speaker. Resistance is measured in ohms and can be measured by a multimeter.

Answer:
Explanation:
As an example, ice on steel has a low coefficient of friction – the two materials slide past each other easily – while rubber on pavement has a high coefficient of friction – the materials do not slide past each other easily. The coefficients of friction ranges from near 0 to greater than 1.
