A200 n wagon is to be pulled up a 30 degree incline at constant speed. how large a force parallel to the incline is needed if friction is negligible?

The best formula to do this is F = mg sin θ  in which mg = 200 and you need to find the sin of 30 degrees. So first step is to find the sin of 30 degrees which woth a calculator equals 0.5. and then based on the formula you multiply 200 by 0.5 and the answer is 100. So F equals100.

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.

Perhaps seek some professional ? it isn't very asking some children who are just trying to find out answers to homework.also, it seems professional would actually be good to you. obviously it isn't going to magically fix your depression, but it'll do something. drugs, smoking weed, it won't do much, especially if your husband is against it. if you do it he'll dislike it. but talk to him, try and get him to listen to you, and figure everything out together, okay? there's a website- maybe it can offer some ?
