Physics
What is potential energy?
Energy at rest, or stored up energy.
This element is in group 8A, and period 3.
How many protons does it have?
How many neutrons does it have?
How many valence electrons?
How many total electrons?
(Ar) Argon
18 protons, 22 neutrons, 8 valence electrons, 18 total electrons.
How many Neutrons does element #34 have?
45 neutrons.
Mushrooms are producers, true or false?
False.
What type of weather can be expected after a cold front?
Clear skies (sunny) and cold temperatures.
What are Newton's Three laws of motion in order?
1. Inertia
2. F=ma
3. Action/reaction
This Ion has 13 protons, and 15 electrons.
What is the chemical symbol of this element?
What is the net charge of this element?
(Al) Aluminium
The element has a net charge of -2
This element has three electron shells and two valence electrons. What is it?
Which trophic level gets about 1% of the original energy produced by a producer?
Secondary consumers.
What can be expected after a warm front?
Cloudy skies (overcast), warm temperatures, and precipitation (rain/snow/etc...)
What is the difference between Speed, Velocity, and acceleration?
Speed= distance/time
Velocity = speed + direction
Acceleration = change in speed or change in direction.
An isotope of Surfer-36 is neutral, so it has the same number of protons and electrons. How many neutrons does it have?
20 neutrons
Triple points!!!
Name three metalloids. Chemical symbols are okay.
B, Si, Ge, As, Sb, Te, Po, Lv, Ts
What are the three symbiotic relationships that involve a parasite and a host?
Mutualism
Commensalism
Parasitism
What are the three types of plate boundaries?
Convergent boundaries
Divergent boundaries
Transform boundaries.
What is the mass in kg of an object moving at 30 m/s2 and has a force of 120 Newtons?
4 kg
Answer in order of the questions.
Which group is the Alkali Metals group?
Which group is the Halogens?
Which group is the Noble Gases?
Which group is the Alkaline Metals group?
Group 1A
Group 7A
Group 8A
Group 2A
Find Gold on the periodic table. What group and period number is it in?
Period 6, group (11 or 1B)
What causes algae blooms?
Runoff from farms send fertilizer and other substances into lakes, and oceans. This causes vegetation to grow rapidly and die causing toxic chemicals and lack of oxygen through the process of decomposition.
(As long as you're close).
What is the difference between continental and oceanic crust?
Oceanic crust is newer and more dense because of the pressure from the ocean above.
A car traveled 92 miles in four hours. What was the vehicles average speed?
23 miles/hour
What determines an element's identity?
What determines an elements reactivity?
Valence electrons determine an elements reactivity.
This element is in period 2 and group 7. Draw it.
Must have two electron shells and seven valence electrons, the element is (F) Fluorine.
What is primary succession?
Pioneer species arrive on a rocky island with no living organisms. They will break down rock and over time soil will begin to form on the island. Other species will follow. From nothing, an ecosystem will develop/
What are some evidence for continental drift?
1. Continents look like puzzle pieces.
2. Fossils of plants and animals are found oceans apart.
3. Seafloor spreading (magnetic fields flip, and younger crust closest to mid-ocean ridges).
