What term describes an educated guess about what the answer to a question might be
The custom of watching fireworks on the Fourth of July would be studied by this social science
A jogger runs at an average speed of 5 ms for 3 minutes then finishes with an average speed of 4 ms for 2 minutes What is his average speed in ms for the run
If a lahar is traveling at 80 kmh how long will it take the lahar to travel 20 km
It will travel that distance in 15 minutes.
The shortest distance from start to finish is called the vector addition
Which of these rates is slowest 1760 yardsminute 60 mihr or 88 ftsec
When you convert it, you will find out that they're all the
same.
How long will it take a driver to drive 300 miles by maintaining a constant speed of 60 miles per hour
Time = Distance/Speed = 300 miles/60 mph = 5 hours
The tangent of an angle equals the ratio of the
Sine of the angle to its cosine.
Which of these measurements is not a scalar quantity
Look at the pie graph pictured How many students ate in the cafeteria
Not an example of centripetal acceleration
A plane flying 100kmh due north encounters a crosswind of 100kmh from the east ie blowing westward What then is the planes velocity relative to the ground
What type of measurement is this 12 feet up scalar or vector
A scalar has distance but no direction.
A vector has distance and direction.
"12 feet up" has distance (12 feet) and direction (up), so is a
vector.
Do Two cars traveling the same speed in opposite directions have the same velocity
No, because velocity includes direction as well as speed.
In order for the velocities to be the same, they would have to go the same speed in the same direction.
What of these is always part of using the scientific method
A question about an observation
What is an increase in the magnitude of velocity called
It is called acceleration.
