Many years ago, scientists concluded that matter is made up of very small particles known as atoms. Why did they accept the idea of atoms even though they could not see them? A) Scientists accepted the statements of wise men from early times.
B) Scientists had faith that they could someday see atoms.
C) Scientists believed that there was no need to prove that atoms exist, since matter exists.
D) Scientists realized that many observations were explained by the idea of atoms.

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
