An object 6.0mm high is placed 18cm from a convex mirror of radius of curvature 18cm .
A) Determine the image distance using the mirror equation
1do+1di=1f. Follow the sign conventions.
B) Determine the image size using the equation for magnification m=hiho=?dido. Follow the sign conventions.
A .228g wires are stretched between two points 77.20 cm apart. The tension in the wire is 618N. Find the frequency of the first harmonic. Reply in units of Hz.
A man pushes a lawn mower on a level lawn with a force of 186 N. If 35 percent of this force is directed downward, how much work is completed by the man in pushing the mower 6.5 m.
A spring with 49 N/m hangs vertically next to a ruler. The end of the spring is next to the 17-{rm cm} mark on the ruler. If a 2.0-{rm kg} mass is now attached to the end of spring, where will the end of the spring line up with the ruler marks.

A cricket ball is bowled at a speed of 144 km/hr. suppose the ball diameter is 70 mm and a drag coefficient 0.45, estimate the drag force in newtons which would be acting on the ball.
What should the charge (sign and magnitude) of a particle of mass 1.487 be for it to remain stationary while placed in a downward-directed electric field of magnitude 630.
A train car with mass m1 = 556 kg is moving to the right with a speed of v1 = 8.6 m/s and collides with a second train car, What is the initial momentum of the first train car
Two spherical objects have a combined mass of 200. The gravitational attraction between them is 8.01×10-6 while their centers are 21.0 apart.
A turbine that uses steam drives an electric generator. The inlet stream flows through a 10 cm diameter pipe to the turbine at 2.5 kg/s at 600°C and 1000 kPa. The exit steam discharges through at 25 cm diameter pipe at 400°C
