Answer:
current I = 38 mA
Explanation:
given data
distance r = 7.2 cm
repel each other force per unit length \frac{F}{l} = 4.2 nN/m
solution
we know 2 wire is parallel and when current flow through these wire they exert force each other due to magnetic field
and current I(1) = I(2) ................1
so
..................2
put here value
4.2 × 
= 
solve it we get
I = 0.038884 A
current I = 38 mA
Answer:
Units. Torque has the dimension of force times distance, symbolically T−2L2M. Although those fundamental dimensions are the same as that for energy or work, official SI literature suggests using the unit newton metre (N⋅m) and never the joule. The unit newton metre is properly denoted N⋅m.
Dimension: M L2T−2
In SI base units: kg⋅m2⋅s−2
Other units: pound-force-feet, lbf⋅inch, ozf⋅in
There are many principles that are classified under the Gestalt Principles. The Gestalt principles believe that any stimulus can be viewed in a very simple form. According to the given image, I can say that the square represents the Gestalt principle of PROXIMITY. Hope this helps.
C. Insulator
It COULD be semi-insulator but i'm sure its C
The correct answer is C. Mercury and Mars have the same gravitational force
Explanation:
This chart compares the different features of two planets in our solar system (Mercury and Mars). In this chart, the only numerical value or feature that is the same for both planets is gravity because for both planets gravity is 1.7 m/s2. This implies the gravitational force or the force that attracts objects towards the center of the planet is the same or that objects are pulled with the same force in both planets. Moreover, this factor depends on others such as mass, density, among others.
