A diverging lens (f = -11.0 cm) is located 25.0 cm to the left of a converging lens (f = 36.0 cm). A 3.40-cm-tall object stands to the left of the diverging lens, exactly at its focal point. (a) Determine the distance of the final image relative to the converging lens. (b) What is the height of the final image (including the proper algebraic sign)?
This situation is like that of a car on a curve that is banked at an angle of 21.50°. If she tries to make the turn without slowing down, what is the minimum distance from the seawall that she can begin making her turn and still keep away from a c..
Determine the new planets mass density to earth mass density
a basketball player who is 2 m tall is standing on the floor 10 m from the basket. If he shoots the ball at a 40.0 degree angle with the horizontal, at what initial speed should he throw so that is goes through the hoop without striking the backbo..
Two identical positive charges exert a repulsive force of 6.6 x10-9 N when separated by a distance of 5.4 10-10 m. what is the charge of each.
Assume this is the innermost line of interference (m = 0) and that speed of sound in air is 331 m/s, find the (linear) frequency of the sound in Hz.
The force of repulsion that two like charges exert on each other is 4.0 N. What will the force be if the distance between the charges is increased to 6 times its original value.
A 3.60-{rm m}-long, 430 {rm kg} steel beam extends horizontally from the point where it has been bolted to the framework of a new building under construction. A 66.0 {rm kg} construction worker stands at the far end of the beam. What is the magnitude..
Nobel laureate Richard Feynman (1918-1988) once said that if two persons stood at arm's length from each other and each person had 1% more electrons than protons, the force of repulsion between them would be enough to lift a "weight" equal to that..
At our distance from the Sun, the intensity of solar radiation is 1370 W/m2. The temperature of the Earth is affected by the greenhouse effect of the atmosphere.
Sally travels by car from one city to another. She drives for 24 min at 63.0 km/h, 52.0 min at 42.0 km/h, and 18.0 min at 81.0 km/h, and she spends 5 min eating lunch and buying gas.
A 102-N grocery cart is pushed 13.0 m by a shopper who exerts a steady horizontal force.
A mass rests on top of the piston. The initial temperature of the system is 305 K and the pressure of the gas is held constant at 137 kPa. The temperature is now increased until the height of the piston rises from 23.4 cm to 27.0 cm. What is the f..
