Answer:
Dr. Engelbart, who would later help develop the computer mouse and other personal computing technologies, theorized that as electronic circuits were made smaller, their components would get faster, require less power and become cheaper to produce — all at an accelerating pace
Answer:
resistance
Explanation:
A strain gauge changes resistance with applied strain.
Answer:
(a) Current density at P is
.
(b) Total current I is 3.257 A
Explanation:
Because question includes symbols and formulas it can be misunderstood. In the question current density is given as below;

where
and
unit vectors.
(a) In order to find the current density at a specific point <em>(P)</em>, we can simply replace the coordinates in the current density equation. Therefore

(b) Total current flowing outward can be calculated by using the relation,

where integral is calculated through the circular band given in the question. We can write the integral as below,

due to unit vector multiplication. Then,

where
. Therefore
