An LC circuit of a 4-mH inductor and a 200nF capacitor. If the maximum energy

stored in the circuit is 10^-4 J, what are the maximum charge on the capacitor and

the maximum current in the circuit? What are the minimum values?

i am reviewing for a test and want to make sure i did these answers right please help out

A box of Chex of mass 1 kg and a box of Corn Flakes of mass 3 kg are accelerated

across a horizontal surface by a horizontal force !F applied from the left to the Chex

box–the Corn Flakes box is on the right side of the chex box. The magnitude of

the frictional force on the Chex box is 2.0 N, and the magnitude of the frictional

force on the Corn Flakes box is 4.0 N. If the magnitude of !F is 12 N, what is the

magnitude of the force on the Corn Flakes box from the Chex box?

2) A block is moved down an incline a distance of 5.0 m from point A to point B by

a force !F that is parallel to the incline and has magnitude 2.0 N. The magnitude

of the frictional force acting on the block is 10 N. If the kinetic energy of the block

increases by 35 J between A and B, how much work is done on the block by the

gravitational force as the block moves from A to B?

2) A locomotive accelerates a 24-car train a long a level track. Every car has a mass

of 5 × 104 kg and is subject to a frictional force f=250 v, where the speed v is in

meters per second and the force f is in Newtons. At the instant when the speed of

the train is 28 km/h, the magnitude of its acceleration is 0.3 m/s2. (a) What is the

tension in the coupling between the first car and the locomotive? (b) If this tension

is equal to the maximum force the locomotive can exert on the train, what is the

steepest grade up which the locomotive can pull the train at 28 km/h?

A locomotive accelerates a 25-car train a long a level track. Every car has a mass

of 5 × 104 kg and is subject to a frictional force f=250 v, where the speed v is in

meters per second and the force f is in Newtons. At the instant when the speed of

the train is 30 km/h, the magnitude of its acceleration is 0.2 m/s2. (a) What is the

tension in the coupling between the first car and the locomotive? (b) If this tension

is equal to the maximum force the locomotive can exert on the train, what is the

steepest grade up which the locomotive can pull the train at 30 km/h?

A baseball leaves the bat of Henry Aaron with a speed of 34-m/s at an angle of

370 above the horizontal . The ball is 1.2-m off the ground when it leaves the bat.

To be a home run, the ball must clear a fence that is 3.0-m high and 106-m from the

home plate. (a) At what times after being hit will it reach the height of the fence?

(b) How far from home plate will the ball be at these times? (c) Will Henry have a

home run? Explain.

I have

y= -1/2 G t^2 + Voy t + Yo

Yo=1.2

X = Vox t = VoCos t

t = x / VoCos

Y = - 1/2 g ( x / VoCos)^2 + X tan + 1.2

Now what?? :}

A= (2.00m)ˆi + (3.00m)ˆj ; !B : 4.00m, at + 65

!C= (−4.00m)ˆi − (6.00m)ˆj ; !D : 5.00m, at − 235

I thought you needed to put them all in the same form.. so for b and d

b = 4cos65 4sin65 = 1.7i + 3.6 j

d= -2.9i + 4.1j

so adding them would be ( 2 + 1.7 -4 -2.9)i (3+3.6 -6 +4.1)

= -3.2i + 4.7j

But then what? that is the some.. but how do you do

(a) unit-vector notation, and as (b) a magnitude.

a tiger is chasing a monkey. The monkey runs in a straight line at a speed of 5 m/s. If the tiger leaps off the ground of a 30 angle and a speed of 14 m/s, at what distance behind the monkey should the tiger leap in order to land on the monkey?

the answer is d=10.17m

Can you please help me set up this problem. I have a test tomorrow and I am trying to study. Thanks :]

We will get there late night and have a few hours of a lay over. what time do the bars in the airport close?

but i also got him a free plan ticket to go to my summer home. Do you think it would be ok to ask him if that can just cover the money i owe him, because if i didn't get him the ticket he would've had to buy a plane ticket. Or do you think he would feel cheated?

how awesome was teh finale?

are you happy that janine won!!

i know this persons name i know he is a sex offender i just want to find out how extreme and what he did.

i'm from the hanson bros generation... just wondering who you guys think is better. =p

in august my friends and i want to go camping. we want wonderful scenery and a secluded camp site. where should we go. we don't it to be to expensive and maybe not tooooo far away from socal. we were thinking possibly big sur or yosemite. not sure though. =)

i love in southern california and i'm pretty much down to do anything in that general area.. not all my friends are 21. i am turning 21 on the 16th (which is a thursday) i have from thursday to sun off work. so do my friends. whats a good idea. =) i don;t want to just go bar hoping or just have a party. ive done that every birthday!

does not change?

The magnitude of teh velocity

the x component of the velocity

the y component

the accelertion

and explain.

please =D

A 10-m-long glider with a mass of 680 kg (including the passengers) is gliding horizontally through the air at 30\;{\rm m}/{\rm s} when a 60 kg skydiver drops out by releasing his grip on the glider.

would it be considered rape or shop lifting??

does not work.. myxer is teh best but not verizon doesnt support them.. ughh.. i really want the song "I'm on a a boat" featuring Tpain... does anyone know where i can get it for free
