The drag on a 2-m-diameter satellite dish due to an 81-km/hr wind is to be determined through a wind tunnel test using a geometrically similar 0.4-m-diameter model dish. Assume standard air for both model and prototype.

The floor of the room is cooler than the ceiling. explain this based on air currents in the room.

A 50-kg satellite circles the Earth in an orbit with a period of 120 min. What minimum energy is required to change the orbit to another circular orbit with a period of 180 min? (Earth: radius = 6.4 106 m, mass = 6.0 1024 kg)

Wave can be described as A. a continuous transmission of energy from one location to the next B. The disturbance of particles in an area C. The transmission of energy through individual particles D. The motion of particles in a medium

A germ is also called a microorganism or a microbe. True False

What is 1.33Ω plus 2Ω?

As a fire truck approached Mary, the pitch of the siren got higher. once the fire truck passed and moved away, the sirens pitch got lower. this change in pitch is because in the sound waves
