a block of weight W on an inclined plane of angle 30deg is attached by a string passing over a pulley to another block of weight 50kg hanging vertically.the coefficient of static friction between the plane and the weight W is 0.3.if the system is just at the point of moving down the plane determine W.

honey: dQ/dt=C_e*de/dv*V*A, Where C_e= charge of an electron= (1.6x10^-19).... de/dv= rate of flow of electrons with respect to volume= 5.0x10^{22[/]ecm[sup]-3}....V=mean drift velocity= 1.00mm/s, since i want to deal in cm, then v=0.1cm/s.... A=area= 1.00mm/s= 0.01cm[su]2[/sup], now that we have gotten all, the parameters, we fix it in the equation..... dQ/dt=(5x10²²)*(0.1)*(0.01)*(1.6x10^-19), after multiplying, dQ/dt= I(current) = 8A...

gr8 job,bt u had to convert to m nt cm.ansa z 8 * 10-12A
bt nt in option anywy jst a trick.

I giv it to u.

a metal wire contains 5.0 *10^-22 electrons per cm3 and has across sectional area of 1.0mm2.if the electrons move along the wire with a meean drift velocity of 1.0mm/s.calaulate the current in amperes in the wire if the electronic charge is 1.6 *10-19c.
A)10A

Lilly001: All we have been hearing so far is ASUU's side of the story. Will
like y'all to read this and get FG's side of the story and truly
know who is deceiving who..
The labour dispute
between the Federal Government and the
Academic Staff Union of Universities (ASUU)
which has resulted in the six-week old strike by the
university lecturers took a worse turn yesterday
with the Federal Government threatening to invoke
its no-work-no-pay policy to force the striking
lecturers back to work.
This was made known by the Secretary to
Government of the Federation, Senator Anyim
Pius Anyim, at a meeting with the chairmen of
university governing councils and vice-chancellors
on Friday who ordered the striking university
lecturers to return to their duty posts while the
pending issues were being resolved. He also
directed all the governing councils of the various
universities to open the gates of the institutions to
students as from next week.
The directives followed the inability of both
parties (FG and ASUU) to reach a definite
agreement on the issue earned allowances to
university workers after about two months of
dialogue and negotiations and the threat by the
union to discontinue talks with government.
The Federal Government also disbursed the N30
billion it provided to support the councils for the
payment of academic earned allowances to
lecturers, at the meeting.
Anyim said this was in addition to the N100 billion
provided by the government to address the
challenges of infrastructural deficit in the system.
He said: “Mr. President is fully committed to
bringing the students back to school and
appreciates the patience of parents and students as
government is making every effort to revitalise the
university system.
“By this demonstration of clear commitment to
revitalise the university system, government hereby
urges every (member of) staff of the nation’s
universities to return to work as all issues are being
resolved.
“With particular reference to the contentious issue
of earned allowances, every (member of) staff of
the universities that is so entitled should verify his
claim with his university council and accordingly
get paid,” he said.
SGF said the Earned Allowances was the major
issue in dispute, adding that traditionally,
universities pay deserving staff but “because of the
amount that ASUU now claims as arrears,
government decided to assist the university
councils to pay.”
He said the Federal Government did not receive
any computation of amount involved until
February, 2013 and that ASUU demanded for an
outrageous sum of N92 billion arrears for three
years’ payment based on percentage range of
between 15 and 20 of personnel cost.
The Minister of Education, Professor Rugayyatu
Ahmed Rufa’i, also said that ASUU actually went
on strike over the initial offer of five per cent of
personnel cost of the entire university staff.
She said that government had addressed all other
issues raised by the union for them to call off the
strike. She maintained that government had no
money to pay the N92 billion academic Earned
Allowances requested by ASUU, insisting that it
was not feasible in view of the current state of the
nation’s economy.
Anyim further said: “After series of discussions
involving the National Assembly; the SGF; the
Chairman of the Needs Assessment Report
Implementation Committee, Governor Gabriel
Suswam; the ministers of Education, Labour; and
the Coordinating Minister for the Economy and
other stakeholders, government has now provided
N30 billion to support the university councils in
settling the Earned Allowances.”
He said all other issues of Consolidated Salary
Structure for Academics in Nigerian Universities
(CONUASS II), amendment of Pensionable
Retirement Age of Academics in the Professorial
Cadre to 70 years have been fully implemented.
Anyim said most of the issues contained in the
2009 agreement, which necessitated the current
strike, have been fully met, except for the Earned
Allowances, which ASUU pegged at N92 billion.
He said, “On July 2nd, 2013, ASUU declared what
it called, ‘total and indefinite strike’ over issues it
says have remained unresolved pertaining to an
agreement it reached with government in 2009. It
is pertinent to narrate the genesis of the 2009
agreement. ASUU went on strike action in 2006
based on their request for a review of personnel
matters, on account of this, government initiated a
Needs Assessment of the University system
comprising federal and state universities. The
negotiations led to the 2009 agreement.
“Some of the issues which bothered on amendment
of pensionable retirement age of academics in the
professorial cadre; consolidated peculiar
allowances (CONPUAA), exclusively for
university teaching staff; National Health Insurance
Scheme (NHIS); setting up of budget monitoring
committee in all public universities have been fully
implemented.”
He said the Federal Government had explained
why ASUU’s demands concerning the transfer of
Federal Government landed property to
universities would not be possible to implement.
“Government has been clear that it cannot transfer
government’s landed property to ASUU because it
has no structure to manage or maintain such
property.
Government is, however, willing to support any
council that sets up a property company with
management structure to compete with others in
the industry,” he stated.
In a related development, the Minister of
Education, Ruqayyatu Rufa’I, at the event in
Abuja, said she expected ASUU to suspend the
strike going by the latest action of government.
She said the situation had generated so much
anxiety on the part of students, parents and
government, and that negotiations on the
remaining issues could continue.
“Government is ready to implement all the
recommendations, particularly as it relates to
revitalisation of the universities system. I want to
assure you that this will be done in the next few
years.
The Minister of Labour and Productivity, Chief
Emeka Wogu; Chairman, Senate Committee on
Education, Senator Uche Chukwumerije; and the
Chairman, House Committee on Education,
Honourable Aminu Suleiman, all attended the
meeting.
This comes after ASUU had on Thursday
foreclosed further talks with the Federal
Government negotiation team, an indication of a
total collapse of negotiations.
Meanwhile, efforts to get the reaction of ASUU
President, Dr. Nasir Isa Fagge, on the development
were unsuccessful as his mobile phone line was
‘unreachable’.
