The figure shows two objects, Q and R, before and after they collide. before
after
Q
R
R
The arrows show the direction of movement of the objects.
The arrows are not to scale.
Explain how momentum is conserved in the collision.
Use Newton's third law and Newlon's second law in your answer.
Newton's second law can be written as
change in momentum
force =
time

If y gets smaller as x gets bigger and y have an relationship?

Two point charges are separated by a certain distance. how does the strength of the electric field produced by the first charge, at the position of the second charge, change if the second charge is doubled? a. the field does not change b. the field strength decreases by half. c. the field strength doubles d. the field strength quadruples

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.)
