can someone explain to me how to do these

consider a 627 N weight held by two cables. the left-handed cable had tension T2 and makes an angle of 48degrees with the ceiling . the right and cable had tension T1 and makes an angle of 35degrees with the ceiling
what is the tension in each cable
10 11
gravity on the surface of the moon is only 1/6 as strong as gravity on earth
the acceleration of gravity is 10m/s^2
what is the weight of a 14kg object on earth (answer in newtons)
weight on moon?
*i thought it would just be 14 times 9.8 for the weight on eearth but i enterd both 137.2 and 137.3 and the computer said it was the wrong answer?
thansk for ur help:)

For the first problem, draw a diagram. (I don't know how a person can do a problem like this without a diagram.) Resolve T1 and T2 into horizontal and vertical components. Since the weight is at rest, there is no net horizontal force, and no net vertical force, on it.
Horizontal forces: T1 cos(35°) -T2 cos(48°) = 0
Vertical forces: T1 sin(35°) + T2 sin(48°) - 627 = 0
Solve for T1 and T2.
For the second problem, don't use 9.8 m/s² for g; use 10 m/s², as the problem indicates.

The Physics discussion board, as presently constituted, is such a lot greater than the Astronomy and Space discussion board. A&S has a tendency to be incredibly smooth. A lot of i. grade college homework, ii. hoaxes (2012 stuff), and iii. trolls browsing for concentration. Even even though homework aid is stressful, a minimum of it's severe. You can typical self-filter out to discover questions that present a little bit task and a questioner who's appreciative. There has been speak among the aficionados of constructing a significant Physics and Math discussion board. But the normal consensus was once that it could nonetheless be filled with homework questions and unsolicited mail trolls, and Y!A could now not be eager at the notion due to the fact what Y!A desires is site visitors.

It's weight on earth would be 137.2 Newtons. It's mass on the moon would be 14 kg. It's weight on the moon would be 22.86666667.
