In physics, the ideal gas law describes the relationship among the pressure, volume, and temperature of a gas sample. this law is represented by the formula pv = nrt, where p is the pressure, v is the volume, t is the temperature, n is the amount of gas, and r is a physical constant. which of the equations below are equivalent to the formula pv = nrt? select all that apply. a. p = vnrt b. v = nrt/p c. n = pv/rt d. r = pvnt e. t = nr/pv

The table shows the total distance that myra runs over different time periods. which describes myra’s distance as time increases? increasing decreasing zero constant

The height of a flare fired from the deck of a ship in distress can be modeled by h(t)= -2(8t^2-52t-28), where h is the height of the flare above water and t is the time in seconds. a. find the time it takes the flare to hit the water.

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
