A particle is moving with a constant velocity in a circle, What is its acceleration?
If a particle is moving in a circle then it can't have constant velocity.And if you are talking about constant speed, then this case is called uniform circular motion.Now an acceleration towards center know as centripetal acceleration will act on body ,so that it can continue it's motion in circle.|a| = v*v/r.Where v=speedr = radius of circle.
I gets many calls regarding jobs, who asks me to deposit some amount of money (1500-2500) for creating a referral before conduction of any interview. Are these reliable?
I guess, am qualified to answer this question as I have been through this desperate phase of “getting job at any cost” after my graduation.Get this, No genuine employer will offer you job without interview for some cheap money or whatever reason. If they are offering a direct job bypassing the interview and asking you to pay for that, its scam and STAY AWAY.I assume the calls you get are regarding job "interviews" in specific. There are some genuine consultancies or human resource organisations which really want to help aspirants to find Jobs they deserve. Such kinds don’t charge anything from candidates, because they will be getting paid by companies. So, if any person/org is asking money for arranging interviews again STAY AWAY.I did little search and found these links on internet. List of fraudulent consultancies / Agencies that you should be aware of.fake COMPANY & CONSULTANCIES- By IBM ,TCS&ACCENTUREfake consultanciesAlso, I strongly advise you to do your own research on the consultancy or agency you got the call from. Apparently, at any given metro city there are at least 50 scamster agencies waiting to con job seekers.While we are at it, I also want to warn you about fake certificate rackets. There are some agencies who offer fake work experience to candidates in exchange for hefty sum of money. There are lot of reasons why you should walk away from such offers. However I'd like to state just one major reason"It's an offence and the offender will end up jobless and will probably never find one in future also"These kind of offers are nothing but troubles disguised as opportunities. Some day they are gonna reveal themselves and cause you lot of painAcquire skills, prepare well for the interviews and earn your job. There are always opportunities for skilled and confident people.
What will be the angle between veCtor a and b if there are three veCtors a ,b and C suCh that veCtor (a+ b+C) =0, and magnitude of a ,b and C be 3,5,7?
a+b+c=0a+b=-c|a+b|=|c|a²+b²+2abcos∆=|c|²9+25+30cos∆=49cos∆=1/2∆=π/3 = 60°
How do I convert joule to eV?
Electron Volt is a unit of energy that is equal to the work done on an electron in accelerating it through a potential difference of one volt.[math]1eV=1.6*10^{-19}J[/math]And this can also be written as,[math]6.25*10^{18}eV=1J[/math]Cheers!
