It's answer #2: potential energy. Kinetic energy is the energy that the ball acquires when it's moving.
Find the present value of the annuity necessary to fund the withdrawal given. $300 per month for 20 years Annuity earns 7% per year thank you for your time.
Evaluate the following algebraic expressions for the given value: 1. 4y-115 if y=7 2. 312 + 78x if x=4 3. 8z2 - 9 if z=3
A flagpole 20ft tall cast a shadow 12ft long on the level ground. Find the angle which the rays of the sun make with horizontal
The 4th term of an arithmetic sequence is 18 and the 6th term is 28. Give the first 3 terms. Use the formula

You roll a number cube numbered one to six 12 times. P(5) = two over three. What type of probability is illustrated and why? (1 point) experimental; the result is based on the number of possible outcomes ** experimental; the result is found by repeating an experiment ...
For what main purpose did European rulers build empires?
The weight W that a horizontal beam can support varies inversely as the length L of the beam. Suppose that a 4-m beam can support 1000 kg. How many kilograms can a 17-m beam support?
#3. amortized is if both the principal and interest rate are paid by a sequence of equal periodic payments Amortization Formula: R=monthly payments (?) P= principal amount ($2419.) i= 5.2% interest rate (0.052/36) n = number of payments (36 months) R = P(i) ------- 1-(1+i)^-n ...
the hundred thousands digit of a six-digit even numbers is 3 more than the thousand digit,which is twice the ones digit.give at least four numbers that satisfy the given condition.

give me a example of the hundred thousand digit of six-digit even numbers is 3 more than the thousand digit,which is twice the the ones digit.give at least four numbers that satisfy the given condition.
Math - To find 62 - 24, you could first find 64 - 24 = 40. Then what should you ...
Never mind, I figured it out!
We used 1g of MgO and .5g of Mg for the experiment. 250ml of 1M HCL was also used.
I'm trying to figure out what went wrong during my freshman chem lab. We were figuring out the enthalpy of formation of MgO(s). MgO(s) + 2H+(aq) -> Mg2+(aq) + H2O(l) dHrxn = -334.83kJ/mol Mg(s) + 2H+(aq) -> Mg2+(aq) + H2(g) dHxrn = -1105kJ/mol H2(g)+ 1/2O2(g) -> ...
tangent of theta is opposite / adjacent. So your theta (angle) here is 50, your opposite is 27, and we don't know the adjacent. So do simple algebra & bring x to the other side by multiplying so you have tan50 * x = 27, now divide tan50 * x by tan50 to get x by itself. Now...
What direction is the bee traveling? Anyways, i don't know...But the trains will collide in exactly 1 hour since the one is going 30 and the other 20. Their distance is 50 km apart. Is it asking if the bee is going 80km/hr, how long will it take to travel 50 km? If so then...
^Yeah theta has to be in degrees, or radians. Sq rt of 15 can't be right
Use your kinematic equations. You know Vix, Ax, Then you'll need to find Vfx
I remember this from last year - you should have a table of the heat of enthalpy somewhere in your book. From this you'll need to get the values of delta H (heat) of each mixture. The left side (HCl + NaOH) is the reaction and the right side is the result - you'll ...
It was kind of windy the other day bring the temperature from -10 degrees centigrade to 18 degrees centigrade in 24 hours. How much did the temp. rise in 24 hours? on average, how much per hour did the temp. rise?
