Two objects, A and B, are brought into contact with each other. The initial temperature of object B is 430 K. The heat capacity of object A is a constant 3 J/K and the heat capacity of object B is a constant 2 J/K. Through the exchange of heat the two objects eventually obtain a common final temperature of 340 K.

1. The initial temperature of object A was K.
2. The amount of heat exchanged during the process of obtaining the final temperature was J.
3. The final temperature would be (higher, lower, stay the same), if the heat capacity of object B was higher and the other given parameters remain constant .

Which of the following explains why it took so long for the public to accept the negative health effects of smoking? a)people were waiting for counter reasons, and those were presented.b)scientists had not completely finalized their results, which took 30 years.c)cigarettes were cheaply available and media channels were very inefficient.d)cigarette manufacturers were trying hard to bring an alternative into the market

Can you match these to the correct definition

Asatellite that goes around the earth once every 24 hours iscalled a geosynchronous satellite. if a geosynchronoussatellite is in an equatorial orbit, its position appearsstationary with respect to a ground station, and it is known as ageostationary satellite find the radius rof the orbit of a geosynchronous satellite that circles the earth.(note that ris measured from the center of the earth, not the surface.) you mayuse the following constants: the universal gravitational constant g is 6.67 \times 10^{-11}\; {\rm n \; m^2 / kg^2}. the mass of the earth is 5.98 \times 10^{24}\; {\rm kg}. the radius of the earth is 6.38 \times 10^{6}\; {\rm m}.
