PLEASE HELP ME LOTS OF POINTS The train that braked was moving at an acceleration of 0.4 m / s ^ 2 for 25 sec. Then its speed is the braking moment and the braking distance is?

SO I THINK ITS a=0,5m/s

t = 25sec

and we need to found V and S?

Which quantities are scalars? choose all that apply a.distance b.speed c. acceleration d.velocity

A5 foot by 5 foot box culvert is buried 6 feet beneath the surface of the ground. a crosssection of this very long culvert (into and out of the page) is illustrated below. assume that the soil in which the culvert is buried has the following properties: jt = 120 pcf, w = 12%, ko = 0.50, ka = 0.33, and kp = 3.00. calculate the total horizontal force per unit length of culvert (fh) felt on one of the vertical faces of the culvert.

What are the similarities & differences between a thermistor and a light dependent resistor in physics?
