a. while flying for 7.2 seconds, how many times will a typical giant hummingbird flap its wings?
b. a ruby-throated hummingbird can flap its wings 4 times faster than a giant hummingbird. how many times will a ruby-throated hummingbird flap its wings in the same amount of time?

a. 90

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
