How many sigfigs does this number have?
0.07390
4
Generates ATP (energy)/Powerhouse of the cell
Solve for d
v=d/t
d=vt
How many diatomic elements are there?
Seven
Name the part you look through on a microscope
Eyepiece
v=d/t
Solve for t
t=d/t
What do ribosomes make?
They can be free floating, or bound to the rough ER.
9.81m/s2
What polyatomic element is this?
What charge does it take?
PO4
Phosphate
-3 charge
What is a closed system?
What is a open system?
Give examples for both.
Closed= no matter/energy can transfer in or out
Ex: closed bag of cereal
Open=matter/energy can be transferred in and out
Ex: a bowl of soup
Convert 14km into m
14km = 1400m
What is diffusion?
Movement of any particle from high to low concentration.
Ex: Candle, essential oil diffuser
What two energies are interchangable?
Kinetic energy and Potential energy
Ep=Ek
How many mols are there in one atom?
6.02 x 1023
What are the TWO laws of thermodynamics?
1. Heat/energy cannot be created/destroyed, can be transformed
2. Heat flows from hot -> cold, not all energy is transferred and some must be lost as heat
Isolate Final Velocity
a=(Vf-Vi)/t
a=Vf-Vi/t
(at) +Vi =(Vf-Vi) + Vi
Vf=at+Vi
What is the difference between pinocytosis and phagocytosis?
Pino= engulfs liquids
Phago= engulfs solids
If someone drives 130km [N], turns around and drives 75km [S], then stops and drives another 85km [N],
What is their total distance?
What is their displacement?
Distance = 290 km
Displacement = 140 km [N]
Name all diatomic elements
Someone does 20J of work to move an empty box 145cm
How much force is used?
F=Wd
F= 20 x 1.45m
F= 29J
Convert 175 km/h into m/s
175 km=175000 m
1h= 3600s
(1/3600) x 175 000 =
48.6m/s
Why can viruses NOT survive outside of a host?
They lack metabolic and reproductive capabilities.
Ep=650J m= 68.2kg g=9.81m/s2
Solve for h
650/(9.81 x 68.2)
650/669.042
h=0.97m
List what kind of reaction, develop & balance the following:
ZrTe2 + Cl6W
Double Replacement Reaction
ZrTe2 + Cl6W= ZrCl4 + Te3W
What differs scalar quantities from vector quantities?
Vector quantities show direction & magnitude
Scalar quantities only show how much (magnitude)
