CONCEPTUAL PHYSICS HELP! [PAYING] [multiple choice]

I need help with these if anyone is willing to I can offer a $5 amazon gift certificate by 2 hours.

What is the relationship in which the ratio of the manipulated variable and the responding variable is constant?
inverse proportion, direct proportion, slope, or interdependent

Displacement vectors of 4km south, 2km north, 5km south, and 5km north combine to a total displacement of: 16km north, 11km west, 6km south, 2km south.

What is the most appropriate SI unit to express the speed of a cyclist in the last leg of a 10-km race? km/s, km/h, mm/s, cm/h

Instantaneous speed is measured when? at the starting point, when the object reaches its destination, at a particular instant, over the duration of the trip.


The slope of a line on a distance-time graph is: distance, time, speed, or displacement.

A car traveled 60 km in 2 hours, 84km in the next 1 hour, and then 68 km in 2 hours before reaching its destination . what was the cars average speed? 212km/h, 42km/h, 148km/h, or 1060 km/h.

Which examlpe identified a change in motion that produces acceleration?

a speed skater moving at a constant speed on a straight track
a ball moving at a constant speed around a circular track
a particle moving in a vacuum at constant velocity
a vehicle moving down the street at a strady speed

which example describes constant acceleration due only to a change in direction
an object in free fall, traveling around a circular track, an object at rest, increasing speed while traveling around a curve.


The motion of an object looks different to observers in different ________


The centripetal force acting on a satellite in orbit
a. acts as an unbalanced force on the satellite
b. changes the direction of the satellite
c. is a center-directed force
d. all of the above

Describe a main idea of physical science that deals with space and time.
How many significant figures will the answer to the calculation 65.25x37.4 have?
What is the relationship between two variables if the product of the variables is constant?

Thanks.

 

Please don't threads like this.
People who do so never give what they offer.

 

go try yahoo answers...

they love answering shit like this.

"A car traveled 60 km in 2 hours, 84km in the next 1 hour, and then 68 km in 2 hours before reaching its destination . what was the cars average speed? 212km/h, 42km/h, 148km/h, or 1060 km/h."

(60 + 84 + 68) / (2 + 1 + 2) = 42.4 km/h

common sense?

Displacement vectors of 4km south, 2km north, 5km south, and 5km north combine to a total displacement of: 16km north, 11km west, 6km south, 2km south.

displacement is distance from start (not travelled) if you didn't know that.

would GUESS this one cause all the others are straight lines
