The drawing shows an a-shaped ladder. both sides of the ladder are equal in length. this ladder is standing on a frictionless horizontal surface, and only the crossbar (which has a negligible mass) of the "a" keeps the ladder from collapsing. the ladder is uniform and has a mass of 14.2 kg. determine the tension in the crossbar of the ladder.

the answer is c.)

explanation:

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

happy to
