What is the horizontal acceleration of a block of mass 10 Kg, if it is pulled to the right with a force of 19 N is applied at an angle of 21º (measured counterclockwise from the +x axis). Give your answer in m/s/s to the nearest integer, without units.

Work = force × a. work b. energy c. distance d. momentum

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 ✕ 103 s. given that the charge of an electron is 1.6022 ✕ 10−19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.

Object a has a length of 3 cm, a width of 2 cm, and a height of 4 cm. object b is dropped into a graduated cylinder. it displaces 19 ml of water. the volume of object a is: a: greater than the volume of object b b: less than the volume of object b c: equal to the volume of object b
