Basic velocity Time graph from SS1
Calculate the displacement between t = 2s and t = 5s of an object that moves along an axis and has the speed characterized below.

Please How is the answer option D, i can only see a trapezium for t=2 & triangle for t=5.

felix00:

Thank u 4 breaking dat down for me.
What course do u wanna study and wat school.....[s]I can't afford to be competing with someone like you for admission[/s]

Med & surg
As for school, I haven't decided yet......more of unijos, maybe unn or even Delsu.

Haba!!! see whining @ your last statement
Thanks for the compliment........

He is going for med and surg.....pity Nigerian uni aren't looking for people with brain....they are looking for people with deep pocket.

Electrical appliances at home are normally earthed so that A. the appliances are maintained at a lower p.d than the earth B. both the a.c and d.c sources can be used C. a person touching the appliances is safe from electric shock D. the appliances are maintained at a higher p.d than the earth

The difference between X-rays and
gamma rays is that A. x-rays are more penetrating than gamma rays B. x-rays are electromagnetic radiations while gamma rays are
negatively charged radiation C. x-rays have higher frequencies than gamma rays D. x-rays arise from energy changes in the electronic structure of atoms
while gamma rays come from the
nucleus

In a hydraulic press , a force of 40N is
applied on the effort piston of area 0.4m2. If the force exerted on the load piston is 400N, the area of the large
piston is A. 4m2 B. 8m2 C. 2m2 D. 1m2

As the pressure of a fluid increases,
its viscosity A. decreases B. increases C. increases then decreases D. remains constant

Optimist1998:

A. predict direction of chemical reaction
B. predict extent of chemical reaction
C. determine the equilibrium concentration of mixture
D. all of above

Conditions for equilibrium of concentration of reactant and products will be same if
A. temperature is constant

Hi,I...um...think the answer to the first and second question is D

The 2nd should be B

Please any reply on this?

I did F2/F1=A2/A1
400/40=x/0.4
40x=400 * 0.4
40x=160
x=4m2 (A)

I swear I pity any uni dat rejects dis guy, dey are missing out on one of d best out there if not d best

You're dealing with triangles within the stipulated 2s to 5s time frame

Same here
Which university did you pick

see how Temilola21 is answering the questions u won't praise her

Temilola21:



D.

do u want more from where those came from??

Hope u aint cheating??

SamanN:



The 2nd should be B

I think Temilola21 is right

Nuel25846:

Duh-uh,I'm not

The change in volume when 450kg of
ice is completely melted is [density of ice = 900 kgm -3, density of water = 100 kgm-3] A. 0.50m3 B. 0.45m3 C. 0.05m3 D. 4.50m3

A 50W electric heater is used to heat
a metal block of mass 5kg. If in 10 minutes a temperature rise of 12oC is achieved, the specific heat capacity of
the metal is A. 400 J kg-1K-1 B. 500 J kg-1K-1 C. 390 J kg-1K-1 D. 130 J kg-1K-1

Please I want to be sure. Are we all going for med and surg

Nuel25846:
As the pressure of a fluid increases,
its viscosity A. decreases B. increases C. increases then decreases D. remains constant

As the pressure increases, the volume decreases leading to less space for them to move freely, with less space you get more friction [for gases]


But pressure has no effect on liquids
Which of the fluids are you referring to...... Gas or liquid?
