Physic Test
I have a Physics test today on electicity and circuits - I need a formula sheet?
Can anyone tell me equations for the following subjects
Charge
Resistance
Voltage
Power
Amps (current)
Thanks!
PS (grade 11 physics)
v=i*r
r=v/i
i=v/r
p=iv ; p= (v^2)/r ; p=(i^2)*r
where:
v- voltage
r-resistance
i-current
p-power

Big D. - Crysis Destruction Physics Madness
simple physic test (Home made)?
A 15 Tonnes boat is about to go through a deep aqueduct which can stand the weight of 20 cube meter of fresh water. The aqueduct is already 74% of its weight capacity with the water it supports..
what happens when the boat stand above the aqueduct ?
A. The aqueduct collapse under the weight
B The aqueduct is OK and the boat goes through
C The boat get stuck
The first one to provide the right answer gets his 4 stars rating but please provide justification for your answer
C The boat gets stuck !!!!
At 74% full there is less than 15 Tonnes of water in the aquaduct. (20t x 74% = 14.8t)
The boat weights 15 tonnes so it is displacing 15 tonnes of seawater in order to float.
There is not enough seawater in the aquaduct (`14.8 tonnes) to support the boat (15 tonnes) so it will ground and get stuck in the Aquaduct.
Edit:
Note a boat enters the aquaduct it displaces a volumne of water equal to the boats weight. An auqaduct allows water to flow freely so as the boat enters the aquaduct an equal volume of water is pushed out (displaced). There is no change in the total weight since water is allowed to flow into and out of the aquaduct freely.
The size of the boats dimensions and shape relative to the dimensions of the aquaduct would come into play if you were comparing a shallow draft vessle like a barge to a sleek hull shaped like a sail boat which would have a deeper draft.
But in this problem there just isn't enough water available in the Aquaduct to support 15T so the shape of the boat is irrelavant. Answer C!

Physic Test
I am studying for a physics test & need a bit of help with the following questions:?
1) Can an object be accelerating while its velocity is zero?
2) How long does it take for a dropped ball to reach the ground? I think this one is 10m/s, am I right?
3)Ignoring air resistance, does a thrown ball accelerate in the horizontal direction?
Any help is appreciated! I want to get a good grade on my test, thanks!
1) YES.
if V=0 and acceleration is - or + the object is speeding up from rest
2) So your looking for time, right? I'll need more info about distance. You know acceleration is -9.8 m/s^2 because it's in free fall, But you need to know the distance! Then you could plug it into either:
VI=VF + A(T)
Distance=VIT+1/2(A)(T)^2
3)No.
*Here's some help with veloctiy and acceleration*
VI= initial velocity A=acceleration
VI=+ A=+ SPEEDING UP
VI=- A=- SPEEDING UP
VI=+ A=- SLOWING DOWN
VI=- A=+ SLOWING DOWN
VI=- or + A=0 CONSTANT VELOCITY
VI=0 A=- or + SPEEDING UP FROM REST
VI=0 A=0 REMAINING AT REST
Hopefully this helps you out a bit ^_^ and good luck =)
