a soccer player kicks a ball straight up into the air at 6 m/s.ignore air resistance.what is the velocity of the ball at its highest point?
The number is 381654729 because 381654729 / 9 = 42406081 38165472 / 8 = 477068 3816547 / 7 = 545221 381654 / 6 = 63609 38165 / 5 = 7633 3816 / 4 = 954 381 / 3 = 127 38 / 2 = 19 3 / 1 = 3
plz help me understand this 1.) 6x - 3y = 6 2.) y= -2/3x +4 y= 2x + 5 2x + 3y = -6 3.) x+y=0 4.) 3x - 4y = -5 x=y+4 x = y+2
A hot 0.25-kg piece of iron is placed in a calorimeter containing room temperature water. How much heat is lost by the iron as it cools from 125 degree C to 75 degree C? I must have the given/work and answer also how much heat is gained by the water
how much heat must be absorbed by a 500 g pot of water to raise the temperature from 20 degree C to 30 degree C?
for each pair of substances, circle the substance with more thermal energy and explain why? A0 500g of water at 35 degree C VS. 500 g of water at 85 degree C B) 500 g of water at 35 degree C VS. 250 g of water at 35 degree C
A person standing on the roof of a building throws a ball directly upward. The ball misses the rooftop on its way down and eventually strikes the ground. The function s(t) = −16t2 + 64t + 80 describes the balls height above the ground, s(t) , in feet, t , seconds a...
For the reaction 1 CaCO3(s) + 2 HCl(aq) <==> 1 CaCl2(aq) + 1 H2O(l) + 1 CO2(g) Calculate K, the equilibrium constant, from thermodynamic data at 293 K. (Hint #1: Assume that S and H do not change with temperature.) (Hint #2: Work in J/mol)
