We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.

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.)
