Diagram (b) is a free-body force diagram for the cupboard. *State the magnitude of force Y.

*Explain why forces X and P must have equal magnitude.

*Calculate the moment of the weight of the cupboard about a point A.
Moment=?

*Calculate the value of force X when h=0.60 m.
Force X=?

*In principle the fixing screws could be positioned anywhere between point A and the top of the
cupboard. Sketch a graph to show how the size of force X would depend on h for values of h from
zero up to 0.60 m.

(*) Mark is qustions.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j

it is b. absorbs thermal energy
