After finding that objects of the same mass do not always float or submerge the same way in a tub of liquid, alexis wrote a new hypothesis to test objects that have the same mass.

if the surface area of an object increases, then it will float higher in the tub, because the object would need to displace more liquid in order to sink all the way down.

what is the dependent variable in this hypothesis?

Aball tossed vertically upward from the ground next to a building passes the bottom of a window 1.8 s after being tossed and passes the top of the window 0.20 s later. the window is 2.0 m high from top to bottom. what was the ball's initial velocity? the unit vector j^ is directed upward. how far is the bottom of the window from the launch position? how high does the ball rise above the launch position?

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?

Which statement correctly describes the current in a circuit that is made up of any two resistors connected in parallel with a battery? a. the current in the battery and in each resistor is the same b. the current the battery equals to the sum of the currents in the resistors c.the current in the battery is less than the current in either resistor d. the current in the battery equals to the product of the currents in the resistors
