Thanks Heureka,

Try looking at this post:)

it is just 58+85   

Look here

(a).  Because the plane is rising at constant velocity (not accelerating) the net vertical force must be zero.  That is the upward force of 8000*sin(65) must equal the weight of the plane.

(b).  Forward acceleration is obtained from mass*acceleration = 8000*cos(65°).  The mass of the plane is its weight divided by g (acceleration of gravity).

(c).  There are two forces acting on the plane:  The 8000N in the direction shown and its weight acting vertically down.  From (a) you know the net vertical force is zero, so can you figure out what is left?

I really like how you have shown your working Geno.   

if you mean how to solve an integer then can you pls give an example like a question containing integers so that we can give you the answer to what your trying to understand?

just put it straight into the calc like that only use round brackets, not the square ones.  :)

I'll start you off:

The relationships between current (i) and voltage (v) for capacitor and inductor are:

i = C*dv/dt     for capacitor

v = L*di/dt     for inductor

If they are connected in series with an ac source (V*sin(ω*t)) the following circuit equation can be written:

L*di/dt + v = V*sin(ω*t)  where v is the voltage across the capacitor.

Differentiate this with respect to time and use the capacitor equation above to get:

L*d²i/dt² + i/C = ω*V*cos(ω*t)

Solve this 2nd-order differential equation for i as a function of t, making use of your initial conditions.

Thank you Melody , Geno and CPhill!im glad you all liked all those pics!and im not sure i can save it for you CPhill becoz that ice cream is just so yum!

Even i miss everyone when im not here so thats why i thought to come!

And CPhill i'll message you about that festival! 

$${\mathtt{\pi}}{\mathtt{\,\times\,}}{\mathtt{5}}{\mathtt{\,\times\,}}{\mathtt{9}} = {\mathtt{141.371\: \!669\: \!411\: \!540\: \!695\: \!7}}$$

look here

$${{\mathtt{3}}}^{{\mathtt{8}}}$$

is entered as 3^8

.

The slope is the coefficient of the x term, so slope = -3/2 here.

The y-intercept is the constant term, so y-intercept = -3 here.

.

Note that density = mass/volume.

The volume occupied by the sodium is Vsodium = 90/970 L = 1000*90/970 mL or 92.78mL.

This reduces the volume available for the gas, so its new density = 4.6/(250 - 92.78) g/mL

$${\frac{{\mathtt{4.6}}}{\left({\mathtt{250}}{\mathtt{\,-\,}}{\mathtt{92.78}}\right)}} = {\frac{{\mathtt{230}}}{{\mathtt{7\,861}}}} = {\mathtt{0.029\: \!258\: \!364\: \!075\: \!817\: \!3}}$$

new density ≈ 0.029 g/mL

.

Yes, that many Newtons.

$${\mathtt{45}}{\mathtt{\,\times\,}}\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{sin}}{\left({\mathtt{35}}^\circ\right)}{\mathtt{\,\small\textbf+\,}}{\mathtt{5}}{\mathtt{\,\times\,}}{\mathtt{9.8}} = {\mathtt{74.810\: \!939\: \!635\: \!795}}$$

.

By the way, don't confuse the symbol N for the normal force with the symbol N meaning Newtons!

N (normal force) = 75 N (Newtons)

 3494^2

do it on the calc on the home page

There is nothing that you can do

are they e as in 10^from the calculator

or 

This is what your teacher might mean. 

24+36=12*2+12*3=12(2+3)

so it will be 75 upward  right  ? 

To  covert Fahrenheit to Celsius, use this "formula"

C = (5/9)(F - 32)   so

C = (5/9)(18 - 32)  =  (5/9)(-14) = about -7.77C

how do you turn a negative variable exponet to a postive one

$$\small{\text{
$
\begin{array}{c}
a^{-x}=\dfrac{1}{a^x} \\\\
\dfrac{1}{a^{-x}}=a^x
\end{array}
$
}}$$

They were really excellent Rosala.

We really miss you when you are not about.  

I am very glad that you are back and that you have bought a fun post with  you. :)

Better put some ice on that, dude
