A woman throws a ball at a vertical wall d = 3.0 m away. The ball is h = 1.5 m above ground when it leaves the woman's hand with an initial velocity of 12 m/s at 45°. When the ball hits the wall, the horizontal component of its velocity is reversed; the vertical component remains unchanged. (Ignore any effects due to air resistance.) (a) Where does the ball hit the ground? m (away from the wall) (b) How long was the ball in the air before it hit the wall? s (c) Where did the ball hit the wall? m (above the ground) (d) How long was the ball in the air after it left the wall? s B was found to be .35s C was found to be 3.87m A and D ended up wrong. Wrong answers were A=7.55m and D=.89s Please help! and please only answer if you get a different answer for A and D.
A galvanometer whose full scale current is 150amps and coal resistance is 75ohms is used with a 1.50 ohms shunt resistor to make an ammeter. what is the largest current that can be measured by the ammeter.
Let us use the uncertainty principle to (very roughly) estimate the size of a hydro- gen atom. Picture the hydrogen atom as an electron orbiting a proton at close to the speed of light.
