Which is accurate about average and instantaneous speed?
O Instantaneous speed is calculated using a longer time interval than average speed.
OAverage speed is calculated using a shorter time interval than instantaneous speed.
O Average speed is calculated using the same size time interval as instantaneous speed.
O Instantaneous speed is calculated using an instant of time and average speed uses an easily
measureable time interval.

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?

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
