A ball is thrown(from 0') straight up at 50' per second, how long before it hits the ground? How high does it go?
How does a body fossil form? Is it just bones and teeth?
explain necessary and sufficient conditions and how providing these is one approach to defining a term
The rim of the London Eye (a 135m diameter ferris wheel) moves 26 cm/sec, slow enough for passengers to safely get on the wheel from the platform (2 meters above ground level) without stopping the wheel at the bottom of its rotation. What's the height at the bottom of the ...
Which of the fundamental American political values does the "Tea Party" most fundamentally support? Do you believe the "Tea Party" is a legitimate heir of the Founding Father's protest against the British? Do you believe the Tea Party will transform Ame...
I calculated tan and sin (theta) for a physics lab experiment -- two-slit interference I had to use this equation y = L tan (theta), with y = 0.25 and L = 2 and tan (theta) came out to be 7.12 in degrees and 0.1243 in radians. I found sin (theta) by using the triangle for X^2 ...
I need a 1.00 W motor to push a garbage compactor so that it squishes some garbage. The garbage has a spring constant of 49.7 N/m. If I am going to squish it 30 cm, determine how much time the compactor takes.
What is the wavelength of waves transmitted by an AM radio station operating at a frequency of 840 kilohertz? Calculate the energy of a photon whose frequency is 2450 megahertz What is the difference in energy for a photon of ultra-violet radiation, wavelength 319 nm and a pho...
