D.It draws objects together in proportion to their mass
Answer:
2354.4 Pa
40221 Pa
Explanation:
= Density = 1000 kg/m³
g = Acceleration due to gravity = 9.81 m/s²
h = Depth
The pressure difference would be
The pressure difference in the first case is 2354.4 Pa
The pressure difference in the second case is 40221 Pa
Answer:
a) initial position = 10m
b) average velocity = 30m/s
Explanation:
The general equation of a motion with constant velocity is given by:
(1)
So: initial position
v: average velocity
t: time
You have the following equation:
(2)
If you compare the equations (1) and (2) you obtain that:
hence:
a) initial position = 10m
b) average velocity = 30m/s
Answer:
1) F1
Explanation:
As the air resistant force depends on the speed of object and its orientation as it falls, it does not depend on the mass of the object. Therefore, air resistant force on 1 coffee filter is the same as the air resistant force on 3 coffee filters.
