If the absolute temperature of an object is tripled, the thermal power radiated by this object (assuming that its emissivity and size are not affected by the temperature change) a. will increase by a factor of 18. b. increase by a factor of 27. c. increase by a factor of 81. d. increase by a factor of 9. e. increase by a factor of 3.

this a false

explanation:

where's the following? you gotta add it to know what the choices are

explanation:

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
