PLEASE HELPP A 275 g block at 100°C is placed in a 65 g brass calorimeter that contains 140 g of water at 15.0°C. If the final temperature of the mixture is
28.0°C, what is the specific heat of the block?
O 0.340 J/gºC
O 0.385 J/gºC
O 0.401 J/g °C
O 0.016 J/g °C

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}.
