Harry Hotrod rounds a corner in his sports car at 50 km/h. The friction force holds him on the road. If he has twice the speed, what must be the friction force to prevent him from skidding off the...
Please help me with this. It looks long, but it really is not. A physics student wants to determine the relationship between the radius of a charged conducting sphere and the magnitude of...
A lab experiment was performed to find the centripetal force on a rotating body which measured mass(m), frequency(n), and radius(r). It was found that Fc=4Π2n2mr. How do I write an expression...
i have to explain this on a paper and i dont know how to start
An electric dipole consists of a pint charge -q at the point (0,a) and a point charge q at the pint(0,-a). Find the electric field at the point (x,0).
What Is Optical Density? Difference between optical and mass density!
An object is falling at a rate that is 60% of the acceleration of gravity therefore it is pressing down on anything below it with: A> 100% of its mass B> 60% of its mass C>...
how to get the time from this given my answer is f=100 p.t= 1/100 t=0.01 sec is that right?
Where are physics laboratories usually located? Inside the colleges? Can you write the agreement saying that once your invention succeeds using their materials then you'll give them some profits of...
. The photo shows physics teacher Marshall Ellenstein walking barefoot on broken glass bottles in his class. What physics concept is Marshall demonstrating, and why is...
58. Which has the higher specific heat capacity: an object that cools quickly or an object of the same mass that cools more slowly?
In a sporting goods store you see what appears to be two identical life preservers of the same size. One is filled with Styrofoam and the other one is filled with lead pellets. If you...
. Show that the water pressure at the bottom of the 50-m-high water tower in Figure 5.3 is 490,000 N/m2, or is approximately 500 kPa
A shell was fired from ground level with an initial speed of 350 m/s at an angle of 30 degrees to the horizontal. Assuming there is no air resistance, calculate: a) its time of flight; b)...
a 2kg blob of putty moving at 3 m/s slams into a 2 kg of putty at rest. what is the initial momentum of the two blobs? what must be the final momentum of the two blobs? Also, calculate the velocity...
Please help! I just do not even know what I'm doing, and currently waiting for tutors to respond to work with me one on one. An unknown fluid could be determined from ρfl=(T-T'')/(T-T')...
A compressed spring has 16 J of potential energy. What's the maximum speed it can impart to a 2 kg object? Answer: 4.0 m/s
Two 5 kg masses are attached to opposite ends of a long massless cord which passes tautly over a massless frictionless pulley. The upper mass is initially held at rest on a table 50 cm from the pulley...
