An Anecdotal Record is a formal observation method.

To create a Frequency count, a teacher must decide what social interactions behaviors, interest areas, or types of play that is to be monitored.

Clothing choices can aid preschoolers’ self-concepts and self-help skills.

A reaction of A produces two products, C and D , according to:A (aq) 2C(aq) + D(aq) When A is placed in the flask, its concentration is 0.050 M. The equilibrium concentration of A is measured to be 0.040 M. What is the equilibrium constant for this reaction?Hint:K = 2, Construct the ICE table :

Part 2 – InstructionsOn the next five problems, SHOW ALL WORK.  After you submit your test, take pictures of your work for the five problems below and upload them to Canvas using the link “TEST 1 Work” that is underneath the link for this test in Canvas.  Make sure that you show all work and write neatly and darkly enough for me to read it.  If I can’t see or read your work, I cannot give you any credit.

A small plane flies 40 km in a direction 60o north of east and then flies 30 km in a direction 15o north of east.  Find the magnitude and direction of its displacement.  Round the displacement to a whole number and the direction to the tenths place.

A projectile is fired at an angle of 20o to the horizontal, and another projectile is fired simultaneously and at the same speed at an angle of 70o to the horizontal. Neglecting air resistance, what is true of the projectile fired at the angle of 70o ?

At what angle in degrees should a cannonball be fired to cover the maximum horizontal distance possible if its initial velocity is 20

A woman starts from the origin and walks 75 m to the left and then walks 50 m to the right. What is her displacement?
