100% Verified Answers
Q1: If a span is 2 hands, and a pace is 6 hands, how many spans
are in a pace
A: 3
Q2: Which off the following are derived units?
Density
Distance
Time
Volume
Acceleration
A: Density, volume, and acceleration
Q3: True or False
"Hand", "Cubit", and "Pace" are all standardized units.
A: False
Q4: Acceleration is defined to be
A: Change in speed over time
Q5: Describe how you might find the volume of an irregularly
shaped solid (give details)?
A: You would find the volume of an irregular shaped object by water displacement. Pour
water into measuring cup and make sure there is space with markings above the water
line so that you can measure the change of volume when you place an object inside and
record your initial levels. Slowly lower your object into the water and record the new
level. Then calculate the difference between the two levels to find the volume.
Q6: 10 inches would equal
A: 25.4 cm
Q7: A cube of length = 2 cm, height = 4 cm, and width = 3 cm,
would have a volume of
A: 24 cm^3
Q8: What is the acceleration of an object when its velocity isn't
changing?
A: If the velocity isn't changing, the acceleration isn't changing which means it would be 0.
, Q9: An object with a density of 3 g/cm^3 and a volume of 10 cm^3
will have a mass of _____ g
A: 30
Q10: The weight of something equals its mass times ...
A: the gravitational acceleration
Q11: A pendulum that does 50 swings in 25 seconds will have a
period of ______ seconds
A: 0.5
Q12: State one of Newton's 3 laws of motion. You can use the short
version if you like.
A: objects have inertia, an unbalanced force produces a proportional acceleration. a= F/m
or F= ma, and action-reaction
Q13: Work is ________ times distance
A: force
Q14: If a 10N force lifts a mass 0.5 meters, the change in
gravitational potential energy is _____ J.
A: 5
Q15: If a 2kg mass is traveling 10 m/s, the mass has a kinetic energy
of...
A: 100 J
Q16: Why do handicap accessible ramps tend to be long and low
angle rather than short and steep?
A: Handicap accessible ramps tend to be long and low angle rather than short and steep
because less force is required to go up a long, low angled ramp than a short, steep one.
Q17: Higher mass and higher drop height result in _______
gravitational potential energy.
A: more
Q18: To find the total amount of work needed to climb a flight of
stairs, you would need to multiply which of the following ...
(select all that apply).
number of steps
your acceleration
height of each step
