Started Strange will end as Strange

Two objects X and Y are observed traveling in space under the influence of the gravitational attraction of the Sun. The closest distance of X to the sun (perihelion) is measured to be r_X,P = 5·10^10m at which point it travels with a speed of v_X,P = 7·10^4 m/s, while for Y the closest distance to the sun is

r_Y,P = 8·10^10m traveling at v_Y,P = 6·10^4 m/s.

a.) Determine which object has a bound orbit around the sun and which one doesn't.

-What I did was get the Sun's escape velocity ( 3.8*10^11 m/s) and since it is more than the velocity of X & Y, I said that they are both bonded orbits, please correct me.

b.) For the object in a bound orbit:

Determine the eccentricity e of the bound orbit. This will require (i) the geometry of an

ellipse, (ii) conservation of angular momentum, and (iii) conservation of energy. Then also find the

lengths of the semi-major and the semi-minor axes, a and b .

c.) Determine its period in years.

d.) Determine the smallest speed of the object in the orbit.

Please explain the steps

Q1. You decide to roll a solid sphere up a ramp of height ℎ, and want it to have a speed at the top equal to V_T. The sphere rolls without slipping. The sphere has radius r, mass m. What linear speed V_B must you give it at the bottom of the ramp in terms of ℎ, V_T, r, m, and/or g?

Simplify your answer as much as possible. (Note: I_CM, sphere=(2/5)MR^2).

I think we should do conservation of energy...but help...

Please explain all the steps

Thank you

Write a MATLAB function the performs the operation of a half-adder, call it half_add. The

function should have two inputs, a and b, and return two outputs, X and c. Then, write another

function, call it full_add, that invokes half_add to perform the operation of a full adder. The

function full_add should have three inputs, a, b and c_in, and return two outputs, s and c_out.

Finally, write a program that uses the function full_add to find and display s and c_out for each

possible combination of a, b, and c_in.

This is what I have so far for the half-adder:

clear all; clc

function [(X,c)] = half_add( (a,b) )

%function to perform the operation of a half-adder

% a and can be logical or numeric binary vectors

a = logical([0 0 1 1]); b = logical([0 1 0 1]); % assigning a and b

for k = 1:4

X(k) = xor(a,b)

c(k) = a(k) & b(k)

end

end

please explain me what to do after this...

Determine whether the limit lim as (x,y) approaches (0,0) xysin(1/(x^2+y^2)) exists or not. If it exists, compute it.

Please give the steps and details.

[-2; -1]

Given are the following two equations in two unknowns.

3 - 4z + 2β = 5z

-3β + 2 = -2β - 4z

Assign z to the element X(1) of the vector X and assign β to the element X(2). Find a

matrix H and a vector C , such that the given equations can be written as: HX C= . Do not

solve the equations.

I can solve for β and plug it into the other equation to get z, then get β, but Is that what the question is asking? please give details of what it should be.

Thank you

Consider the circular motion r(t) = <3 cos(5t), 3 sin(5t)>. Find its ve-

locity and its acceleration. How do they compare with the position

function at any point in time (i.e. are they parallel, orthogonal or

some other type of special relative position)?

Suppose that the acceleration is given by a(t) = <cos t; 2 sin t>, the

initial position is given by <1, 0> and the initial velocity by <0, 1>. Then

find the vector valued functions that give the position and the velocity.

I have heard that it has Zinc Stearate- fatty acid derived from swine. I am not sure, please tell me only if you know. And give source. tell me whose fatwa is it, what fiqh is he from and is there a concescus, and tell me all the sources please.

Please give it with proof from Quran and Sunnah

“Anas bin Malik (radi Allahu anhu) narrated that the Prophet (sal Allahu alaihi wa sallam) would breathe three times in the vessel and say: ‘It is more wholesome and thirst quenching.’” [The Chapter on Drinks: Jami At-Tirmidhi]

Breathing three times while drinking means that he would not gulp all the water down in one go but take breaks to breathe. These breaths would be released and drawn outside the glass. This style of drinking distinguishes man from animals as the Prophet (sal Allahu alaihi wa sallam) told us not to drink all at once like a camel.

“Breathe three times in the vessel” means that while drinking from the vessel he used to draw his mouth away from the vessel three times and breathe outside. There is a Sahih hadith that the Messenger of Allah (sal Allahu alaihi wa sallam) forbade breathing in the vessel. The reason being that, by doing so, the foul smell of the mouth penetrates into the water or else, more often than not, the saliva finds its way into the water, which even the drinker himself would detest. Breathing outside the glass or cup, on the contrary, is more satisfying, healthy and pleasant for the stomach.

The Sahabah asked the Prophet (sal Allahu alaihi wa sallam) about the buildings of Jannah and he replied: “Bricks of gold and silver. Its mortar is fragrant musk. Its pebbles are pearls and sapphires. Its soil is saffron. Whoever enters it will live in luxury and happiness and will never experience any hardship or misery; he will live forever and never die. Their clothes will never wear out and their youth will never fade.” [Ahmad, Tirmidhi]

Just try to imagine a home that belongs to you made of delicate bricks of gold and silver. Grey mortar doesn’t bind the bricks together but a perfume! The driveway leading to your house isn’t full of grey pebbles but lustrous pearls and and clear blue sapphires. Imagine walking on them as you lead your guests into your new home. They don’t tarnish, break, get dirty or messed up in the least with use! It looks like a brand new driveway forever. Imagine soil that is sweet smelling saffron… what kind of flowers would grow out of it…
