On your cousin's wedding day you leave for the church 30.0 min before the ceremony is to begin, which should leave plenty of time since the church is only 17.0 km away. On the way, however, you have to make an unanticipated stop because of road construction work. As a result your average speed for the first 15 min is only 11.0 km/h. What average speed do you need to have on the remainder of the trip to get you to the church on time? Express your answer to three significant figures and include the appropriate units.

According to valence bond theory, which orbitals overlap in the formation of the bond in hf according to valence bond theory, which orbitals overlap in the formation of the bond in hf 2s on h and 2p on f 1s on h and 2s on f 1s on h and 1p on f 1s on h and 2p on f 1s on h and 3p on f

Astone is dropped from the upper observation deck of a tower, 250 m above the ground. (assume g = 9.8 m/s2.) (a) find the distance (in meters) of the stone above ground level at time t. h(t) = (b) how long does it take the stone to reach the ground? (round your answer to two decimal places.) s (c) with what velocity does it strike the ground? (round your answer to one decimal place.) m/s (d) if the stone is thrown downward with a speed of 2 m/s, how long does it take to reach the ground? (round your answer to two decimal places.) s
