Ms. Sue, you didn't even help the poor guy (or girl?). To compare, you have to find the range between the two. The range is 6 years.

Thank you!!

Sled accelerates at 2m/s^2. If net force is tripled and mass is doubled then what is the new acceleration of the sled?

Physics! Help
Calculate the net or resultant force in N in x direction given that F1=96.2 N is applied at angle of α=55.4° and a second F2=11.6 N is applied at angle of β=41.2°. See attached figure. Express your answer to 4 significant figures.

ohn and Jack are planning to do a physics lab related to vectors. Starting at the door of their physics classroom, they walk 2.0 meters, south. They make a right hand turn and walk 16.0 meters, west. They turn right again and walk 24.0 meters, north. They then turn left and ...

Given the following information about a sample, calculate a z score for a test grade of 91. = 87, s = 4.01

Find the diagonal length of a square with a side of the square measuring 5 centimetres?

science - chemistry (Le Chatelier's)
How does the concentration of the reactants affect the amount of product obtained? In general, does an increased concentration of reactant give more product? What are the exceptions? Does it matter if it's exothermic or endothermic? If the reactants/products are in liquid/...

In electrochemistry, why is my experimental voltage value of my cell lower than the standard electrode potential? I used zinc and copper as the electrodes and connected zinc sulphate and copper(II) sulphate using a salt bridge. I got 0.85V instead of 1.10V. I've read that ...
