a truck carries a 5.2 ton load of gravel.with this load it accelerates at 0.36m/s without a load the truck accelerate at 0.62m/s.what is the mass of the truck?the accelerating total force are the same in both area
250 mL of ethyl alcohol is placed in a Pyrex glass to the brim at 0°C. How much is the expansion of ethyl alcohol after heating it to 50°C? the expansion of glass? Will the ethyl alcohol overflow? (β of ethyl alcohol is 100 X 10-6 / °C and of Pyrex glass is 3.2 10-6 / °C)
In the figure, a cube of edge length a = 3.70 m sits with one corner at the origin of an xyz coordinate system. A body diagonal is a line that extends from one corner to another through the center. Find the angle between each pair of body diagonals.
A car’s engine provides a forward force of 500 N. It is opposed by a resistive force of 200 N. The car accelerates forwards for 20 m. How much work is done by each force? By how much does the car’s energy increase?
the mass of a typical car is m=1000 kg, so it's weight on the earth's surface is mg=9800N. suppose you have two containers, one with N electrons and another with N protons. These two containers are placed a distance 10 m apart, and the electric force between them is equal to the weight of the car. find N.
Convert 4.77 picojoules to electron volts.
What is the potential at a point 18 m away from a 17.14 mC charge?
A 0.750-cm diameter shell contains a uniformly distributed charge of 65.4 pC on its surface. Determine
the potential near the surface of the sphere.
A sphere has a radius of 9 m. Determine the potential if the charge at the sphere’s center has a magnitude
of 567 mC.
What will be the electric potential 4.3✕10 -14 m from the same fragment if it contains 25 electrons instead?
