A car travels at 15M/s for 10s. it then speeds up with a constant. acceleration not 2.0m/s ^2 for 15s. At the end of this time , what was the total distant traveled by the car

Why does the input force have to be greater than the force needed to lift the bale?

What are segments of dna that code for a particular trait. a combination of dna and proteins make up what

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?
