Activity of Integration 5 (page 54) Imagine one of the daily newspapers in your country has published an article entitled "The sun will soon stop moving". The National Science Forum has organized a conference to discuss the newspaper article, and your school has been invited to participate in the discussion. Using the knowledge, you have learnt in this chapter, prepare a paper of at least one and a half pages that you will present at the conference. In your paper, point out the likely effects on time and people's lives if the sun stopped moving.

Debbie places two shopping carts in a cart corral she pushes the first cart which then pushes a second cart what force is being exerted

What is the energy of a photon of ultraviolet radiation with a frequency of 4.4 × 1015 hz? planck’s constant is 6.63 × 10–34

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
