Answer: acceleration can be calculated when a known force is acting on an object of known mass. Newton’s law can be represented by the equation F net = m x a, where F net is the total force acting on the object, m is the object’s mass, and a is the acceleration of the object.

Can you solve it descriptively . thanks

Answer:

$|M_y| = 170.82 \ N.mm$

Explanation:

From the diagram affixed below completes the question

Now from the diagram; We need to resolve the force at point A into (3) components ; i.e x.y. & z directions which are equivalent to $F_x \ , F_y \ , F_z$

So;

$F_x$ = positive x axis

$F_y =$ Negative y axis

$F_z$ = positive z axis

Then;

$|M_x| = F_y *27-F_z*11 = 77 ----- equation(1) \\ \\ |M_z| = F_y*4 - F_x*11 = 81 ---- equation (2) \\ \\ |M_y| = F_x *27 - F_z *4 = ? ---- equation (3)$

From equation (1); Let's make $F_y$ the subject of the formula ; then :

$F_y = \frac{77+11F_z}{27}$

Substituting the value for $F_y$ into equation (2) ; we have:

$(\frac{77+11F_z}{27})4-F_x*11=81 \\ \\ 11(\frac{7+F_z}{27} ) 4- F_x -11 =81 \\ \\ 28+4 F_z - 27F_x = \frac{81*27}{11} \\ \\ 4F_z - 27F_x = 198.82 -28 \\ \\ 4F_z - 27F_x = 170.82 \\ \\ Since \ |M_y| = 4F_z-27F_x \\ \\ Then: \\ \\ \\ |M_y| = 170.82 \ N.mm$

Improving our use of both solar energy and wind energy will depend on the development of batteries. Why are these two energy sou

victus00 [196]

Answer:

The batteries make it possible to store the electricity generated when the sun and wind peak so it can be available to the grid when electricity demand is at its peak.
