Answer:
0.25m²
Explanation:
We know that the summation of forces in the vertical direction is zero
So
PA-mg=0
A=mg/p
So
Substituting
A= 75* 9.8/3*10^-3
=0.25m² which is the total shoe area
The common formula for work is:
Work = force x displacement
W = F x d
Answer:
C. scientists possess varied talents and interests.
Explanation:
The above passage suggests clearly that often times, scientists possess varied talents and interests.
Cases were made of Abū Rayhān al-Bīrūnī and Robert Hooke. Both were scientists and had the same time had interests in other disciplines.
- Abū Rayhān al-Bīrūnī, a Persian made scientific contribution to the studies of heat, more so, his interest in cultures lucidly made him an erudite and foremost founding father of anthropology. Physics/mathematics and Anthropology are different fields with varied interests.
- Robert Hooke, was interested in physics. Besides this, he was skilled architect and surveyor. Physics and architecture/surveying are different fields. They are varied and dissimilar in nature.
Therefore, we can argue that the tone set by the author conveys a clear focal point that often times, scientists possess varied talents and interests.
