Until it was recently discontinued, the fastest jet plane in the skies was the Lockheed SR-71 Blackbird. However, this plane did not reach its high speeds through large acceleration. The plane had a mass of 7.7 x 104 kg and was driven by an estimated unbalanced force of about 7.23 x 105 N. What was the acceleration of the Lockheed SR-71 ?

Crowbar of 5 metre is used to lift an object of 800 metre if the effort arm is 200cm calculate the force applied

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?

The starship enterprise is caught in a time warp and spock is forced to use the primitive techniques of the 20th century to determine the specific heat capacity of an unknown mineral. the 125-g sample was heated to 96.3°c and placed into a calorimeter containing 85.9 g of water at 20.0°c. the heat capacity of the calorimeter was 14.2 j/k. the final temperature in the calorimeter was 24.5°c. what is the specific heat capacity (in j/g°c) of the mineral? enter to 4 decimal places.
