Thanks for the help. For number 2, the only answers I'm given are the ones up there. So if tanto, como isn't correct, would the best answer be (mas, que)? And I meant to put pensando, but I forgot the n. 11 should've said pensando
This is a three part question. First part is to calculate the amount of energy necessary to turn -10 C ice into 0 C water. Next is calculating the energy to convert 0 C water into 100 C steam. Then calculating the amount of energy to raise the steam 10 C
Kinematics time: First you need to realize that x and y act independently of each other. If you drop a ball straight downwards, it's not going to suddenly accelerate in the x direction. Next draw a free body diagram. The only force that is theoretically
Best way to solve it is using a calculator and taking advantage of the arc functions (cos^-1 or tan^-1) to solve it. arcCos^-1 (-1)= answer arcTan^-1 (-1) = answer if you can't use a calculator, then try to remember the unit circle. cos(y) = -1 when y = pi
Hypotheses generally make predictions about what will happen. The hypothesis isn't always correct, but it's important to make one before you experiment. Example Hypothesis: More people like cats over dogs in my class. Here I make a prediction that could be
Thanks so much :)
Diffusion and Osmosis, although they have similar end results, are caused for different reasons; you could technically argue that Osmosis is a specific type of Diffusion. To begin, Osmosis for the most part deals primarily with water and its solutes
Define variables. x=Jackson's current age Set the equations up by: x-7=2/5(x+20) solve for x 5x-35=2x+40 (I multiplied both sides by 5 and distributed the 2 to the (x+20)). Isolate x 3x=75 ANSWER: x=25 Now check the answer. 7 years ago from 25 would mean
So you're given the limitation of 500 cm^2. This is essentially the surface area of the different solids if you choose to form them into that shape. The best way to calculate the maximum volume with a fixed surface area is to find the ratio of volume to
Area for a rectangle is width times length. A=W*L Define the variables. A= 1/2 yards^2 L= 2/3 yards W=? Then isolate the variable Width (w). W = A/L Plug in your known values. Width = 1/2 yards^2/(2/3 yards) If you're uncomfortable using fractions within
