You are looking at satellite data for a cloud. It reflects about 40% of the light that hits it, and has a brightness temperature of 270 K. The surface surrounding the cloud appears to have a brightness temperature of 295 K. What would be a good estimate for the temperature of the cloud

Two particles of masses m and 2m are placed on a smooth horizontal table. a string, which joins these two masses, hangs over the edge supporting a pulley, which suspends a particle of mass 3m.the pulley has negligible mass. the two parts of the string on the table are parallel and perpendicular to the edge of the table. the hanging parts of the string are vertical. find the acceleration of the particle of mass 3m.

Notice how they put future which of the clouds shown would indicate a possible future rain storm? a) b) c) d)

An object with a mass of 1.5 kg changes its velocity from + 15 m/s to +22 m/s during a time interval of 3.5 seconds. what impulse was delivered to the objects?
