I'm not sure whether I can post a business homework here, but anyway... I'm a business student and currently doing some project about confectionery industries around the world. I have already gathered enough information about the confectionery industries in different countries such as in Australia, Canada, Malaysia and many more. However, I got stuck with Cuba since I don't have enough sources to identify its domestic or international confectionery industries. Do this country have this kind of industry? If so, what is its confectionery industry domestic volume? revenue? profit? How many domestic and international confectionery manufacturers/wholesalers/retailers are there? Does anyone know any sites or links where I can gather information with regards to this country?

oh nevermind, i got it. so simple

Complete the the reaction below. What type of reaction is it?

yes i got a similar graph, but how can i find the value for the ionization for Cs?

If it is right, I'll do it with the ionization energy. Thank you for checking it well I don't think it will work for the Ionization energy Li=0.52 Mj.mol-1 Na=0.50 Mj.mol-1 K=0.42 Mj.mol-1 their rates are different :/

yeah, Cs will be larger than the ones above it.

For the atomic radii, it increases as you go down the group and decreases across the periodic table. The highest atomic radii(peaks of my graph) is found in group 1A while the lowest atomic radii (troughs of my graph) is found in group 8A (noble gases). This is vice versa with the ionization energy.

Hi I am doing a project about analyzing different trends on the periodic table using some data of the first 20 elements. I already graphed their data and answered all of the questions that I'm required to answer, but I'm stuck with this question because I'm not sure how to do it. Can someone help me? Thanks. Here is the question: Using graphical method or any other, estimate the atomic radius and predict a first ionization energy for Cesium.

oh nevermind, i got it. thanks for the time

Electric field (E) is in the positive z-direction, magnetic field (B) is in the positive Y-direction and the velocity of the proton is in the positive X-direction. What is the direction of the electric force? magnetic force? I think the electriic force willl be on the z-direction and the magnetic force will be on the x-direction but i think i'm wrong :/

Can you please check my work? thanks

How can I change my username? Can I still change my username if I already changed it once?

alright thanks

In millikan oil drop experiment, is terminal velocity same for all the drops? I am doing the experiment and i got different velocities for the drop, should i calculate for the average velocity? I need it to calculate for the charge.

Question : If you are given the total mass of clips in each four containers and without knowing how many numbers of clips are there, how will you find out the mass of one clip? First container: 7.5 g Second container: 20 g Third container: 50 g Fourth container: 125 g I have no idea how this relates to our topic in class. Our topic in class is about the Millikan Oil drop and J.J thompson's charge-to-mass ratio.

A spring is hanging from a ceiling, and you attached a mass to it. First scenario: You support the mass by your hand from the spring's uncompressed position and slowly released it at it goes to stop. Second scenario: From the uncompressed position of the spring, you let the mass dropped quickly. Question: Is the maximum (extension) stretch of the spring when mass is dropped quickly, equal to the stretch of the string when the mass is released slowly?

For c I said that the total energy after the balls were realeased is the same or equal to their total energy before they were released since friction is neglected. (energy is conserved) for d i solved it using the conservation of energy and i got v=sqrt(2gh) THank you very much I alrready searched for it, but the mathematical explanations are too advanced for my level so I don't quite understand it but the videos are interesting Yes

My answer for a is the Y-track My reason (for b) is because Y-track has more steeper slope which will give the ball a greater speed. I need to explain it further, I just need help with letter B. I already finished C and D oh i think i posted my question in the wrong section, sorry

An athlete with a mass of 62 kg jumps and lands on the ground on his feet. Th e ground exerts a total force of 1.1 x 10 ^ 3 N [backward 55°up] on his feet. Calculate the acceleration of the athlete.

Hi I have a project and it's obviuously about projectiles. I need to build my own mechanical machine to launch my projectile, like a catapult or something. The goal is to hit a target that is 5-8 m away from the starting point, and I will be tested by it's accuracy and distance. I'm thinking about a machine which I can adjust the angle, and measure the force that will be applied to the projectile.. any ideas how can I do this? I need plenty suggestions. THANKS!

AAAHH YESS!! x+50 is the whole range i get it! thank soo muchhh!! your a lifesaver !
