Acar traveling at 70 mph70 mph down the interstate collides with a bug trying to cross the highway. which of the following statements best describes this collision? the car exerts a smaller force on the bug than the bug exerts on the car. the car exerts a larger force on the bug than the bug exerts on the car. neither exerts a force on the other. the bug gets smashed because it got in the way of the car. the car exerts a force on the bug but the bug does not exert a force on the car. the car exerts the same sized force on the bug as the bug exerts on the car.

What is the relationship between the wavelength of a wave and it's energy?

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 790 n/m. it is initially at rest on an inclined plane that is at an angle of 28 degrees with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is k = 0.14. in the initial position, where the spring is compressed by a distance of a = 0.18 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

In a simplified model of the human eye, the aqueous and vitreous humors and the lens all have a refractive index of 1.40, and all the refraction occurs at the cornea, whose vertex is 2.60 cm from the retina. what should be the radius of curvature of the cornea such that the image of an object 40.0 cm from the cornea’s vertex is focused on the retina?
