If there is no friction, the force that moves the box forward horizontally must be matched by the same force.
If there is friction, then the force moving it forward = frictional force + the additional force you need to add.
Answer:
B. 83.3 cfm
Explanation:
given that the rate of change is,
= 10000 ft³ per 2 hour (note 2 hours = 60 min x 2 = 120 min)
= 10000 ft³ per 120 min
= 10000 / 120 ft³ per min
= 83.3 ft³ per min
Hello
You expect to see:
1) A solar eclipse, when the earth is between the sun and the moon: the shadow of the earth is projected on the moon surface, and the sun will appear dark
2) An "earth eclipse", when the moon is between the sun and the earth: the shadow of the moon is projected on the earth surface, therefore the earth will appear dark.
Answer:
Explanation: The periodic table contains rows and columns. To find how many valence electrons are in an element, simply locate the column number that it is in, and that determines the number of valence electrons in an element. This rule works only for elements excluding the transition metals
Explanation:
0.4375 m/s^2
Acceleration is change in velocity over time
Change in velocity (Vf-Vi) 9.7m/s - 6.2m/s = 3.5 m/s
Time is 8 seconds
Acceleration = 3.5m/s / 8s = 0.4375 m/s^2
