deepta and abhinav having weight 450N and 350N are playing seesaw. If deepta sits at a distance of 2cm from fulcrum, how far should abhinav be seated in order to balance feel ya?​

Answers

Answer:

The distance Abhinav should be seated from the fulcrum in order to balance the seesaw is 2.57 cm

Explanation:

For mechanical advantage of a seesaw, we have

Work done by Deepta = Work done by Abhinav

Weight of Deepta × Distance of Deepta from fulcrum = Weight of Abhinav × Distance of Abhinav from fulcrum

The given information are;

The weight of Deepta = 450 N

The weight of Abhinav = 350 N

The distance of Deepta from the fulcrum = 2 cm = 0.02 m

The distance of Abhinav from the fulcrum = X

Which gives;

450 × 0.02 = 350 × X

X = 450 × 0.02/350 = 0.0257 m = 2.57 cm

Therefore, Abhinav should be seated at 2.57 cm from the fulcrum in order to balance the seesaw.

How can you stop yourself from starving yourself when depressed?​

Answers

Answer: Honest Awnser

I'm going to be briefly honest with you. I'm not sure if this is a real question or one simply because you're feeling this way. If you're wanting to starve yourself due to depression/feeling bigger. I would simply first talk with someone such as an adult or a doctor to seek help and guidance if you're in need of it. There is no way of just stopping yourself if it is a severe wanting to do something such as starve yourself. But, if it isn't severe I'd slowly move yourself to eat, starting with small snacks to small meals slowly. Don't overdo it by making yourself each a huge meal, but slowly add up to a normal meal.

John is a 15 year old young man who is struggling in school, smoking pot, and rebelling pretty strongly against his parents. He tells the therapist that his parents are "devils from hell" and he hates them. He also seems to be depressed and not wanting to do much of anything but smoke. Give 3 possible diagnoses for John and explain why you selected each one.

Answers

Answer: Despite his hatred towards his parents, I would definitely suggest to John that it would be probably a good idea to take some time out of your day and talk to his parents, let them know how he truly feels. Why? Because if he does, maybe his parents will realize the bad things they have done to make John feel the way he feels, and change the way they act.

Another suggestion that I would provide John would be to stay calm, and avoid anything negative. Why? If he does this, over-time, his depression would get better, instead of the negative things in his life making it worse.

Lastly, another suggestion I would provide John includes medical attention. Depression can’t be cured just with avoiding problems. You need to take medicine as well. So, what I would suggest is for John to go see a doctor who is familiar with depression, anxiety, and all that Jazz, so that the doctor can provide John a few medicines he should take daily.

Despite the fact that John despises his parents, I would urge him to talk to them and let them know how he really feels.

What is depression?

Depression is defined as a widespread and significant medical condition that has an adverse impact on how you feel, think, and behave. Major depression is challenging since it has numerous underlying causes. The way your brain controls your moods can be impacted by elements like genetic susceptibility, extreme life stressors, substances you may use, and medical disorders.

John would also get medical care from me. Avoiding difficulties alone won't help someone with depression. You must also take your medication. Therefore, I advise John to visit a doctor who is experienced in treating depression, anxiety, and other related conditions so that the doctor can prescribe a few medications for John to take every day.

Thus, despite the fact that John despises his parents, I would urge him to talk to them and let them know how he really feels.
