Anetwork engineer is subnetting the 10.0.240.0/20 network into smaller subnets. each new subnet will contain between a minimum of 20 hosts and a maximum of 30 hosts. which subnet mask will meet these requirements?
a. 255.255.224.0
b. 255.255.240.0
c. 255.255.255.224
d. 255.255.255.240

A1000-kg weather rocket is launched straight up. the rocket motor provides a constant acceleration for 16-s, then the motor stops. the rocket altitude 20-s after launch is 510-m. you can ignore any effects of air resistance. a. what was the rocket’s acceleration during the first 16-s? b. what is the rocket’s speed as it passes through a cloud 5100-m above the ground?

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

If two students are running down the hall toward each other, trying to get to class, and they have the same mass and acceleration, what will happen when they collide? will their forces cancel out or will each one experience a reaction?
