It is often useful to have an intuitive feel for the magnitude of physical units. In physics, force is typically measured in units of newtons (N). In each of the scenarios, decide which value for the force is most reasonable, and place the appropriate label.

a. The force you exert on the handle of a screen door as you open the door is on the order of: .
b. The force exerted by a honeybee as it lands on a flower is on the order of: .
c. The thrust force produced by the engines of a passenger jet as it takes off is on the order of: .
d. The weight of the largest aircraft carriers is on the order of:

An object is 10. cm from the mirror, its height is 3.0 cm, and the focal length is 2.0 cm. what is the image height? (indicate the object orientation by including the + or - sign with the answer.) hi = cm +1.33 -1.33 +0.75 -0.75

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?

While you are driving in the lane next to the curb on a multi-lane road the car on your left suddenly moves toward you lane. they are about toy crash into your front fender. you
