A 5 kg object is suspended by a string from the ceiling of an elevator.
The acceleration of gravity is 9.8 m/s

Determine the tension in the string if it is
accelerating upward at a rate of 5.3 m/s

Answer in units of N.

The temperature in gavin's oven is a sinusoidal function of time. gavin sets his oven so that it has a maximum temperature of 280°f and a minimum temperature of 240°. once the temperature hits 280°, it takes 20 minutes before it is 280° again. gavin's cake needs to be in the oven for 30 minutes at temperatures at or above 270°. he puts the cake into the oven when it is at 260° and rising. how long will gavin need to leave the cake in the oven? (round your answer to the nearest minute.)
