Because of the conditions that give rise to them, tornadoes do not have
the widespread destructive effects of hurricanes. Nevertheless, the
winds encountered in some tornadoes are even greater than those at
the eyewall of a hurricane. Suppose a small pebble is swept up in a tor-
nado. The pebble is 3.81 m from the center of the tornado and has a
tangential speed equal to that of the surrounding wind: 124 m/s. What
is the magnitude of the centripetal acceleration of the pebble?

In the circuit shown below, with each bulb holding a resistance of 60 ohms, how many amps of current are flowing? express your number as a decimal.

1. what is the relationship between wavelength and the penetrating power of an electromagnetic wave? a) the penetrating power has no relationship to the wavelength. b) the penetrating power increases as the wavelength increases. c) the penetrating power decreases as the wavelength increases. d) the penetrating power decreases as the wavelength decreases. 2. as ice melts and turns into water, the speed of sound through the material would most likely do what? justify your answer. a) the speed would not change because the material is always water. b) the speed of sound would increase because the density of water is less than that of ice. c) the speed of sound would increase because energy is added to ice in order to make it melt. d) the speed of sound would decrease because sound travels faster through solids than liquids. 3.which of these waves need a medium to travel through? a) sound b) x-rays c) infrared rays d) visible light
