What is the Metric unit for mass in science
A plane is uniformly accelerated from 60 ms to 80 ms in 12 seconds what is the distance traveled by the plane during this period
((60m/s+80m/s)/2)x12s=840m
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
How long will it take a sailboat traveling at the rate of 5 miles per hour to sail 120 miles
It will take a sailboat 24 hours traveling at 5 miles per hour
to sail 120 miles.
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 far will a driver go by maintaining a constant speed of 70 miles per hour and driving for 6 hours
The tangent of an angle equals the ratio of the
Sine of the angle to its cosine.
If I have a right triangle The side opposite angle A is 6 meters and the side adjacent angle A is 8 meters How long is the hypotenuse
Which of these measurements is not a scalar quantity
A man accepts a bet and circumnavigates the earth in 80 days Using 6200 miles as the circumference of the earth at his latitude determine the average speed in miles over hour
If a right triangle is 12.5 meters and the side opposite a 30 angle. how long is the hypotenuse
If a right triangle is 12.5 meters and the side opposite a 30 angle, the hypotenuse length will be: 14.43 meters.
A driver traveling at a speed of 21 ms tops a hill and spots a deer standing in the middle of the road 90 meters away He hits the brakes and panic stops the car in 8 seconds How far did the car travel
Assuming that his acceleration was linear (ie. that he slowed
down at a perfectly steady rate), then you can say his velocity at
any point in those eight seconds was:
21 - t(21 / 8) m/s
To get the distance covered in that time, you can simply take
the area under that line between 0 seconds and eight seconds.
Because it's linear, this is very easy. You're dealing with a right
triangle that is 8 seconds wide and 21 meters per second tall. With
a triangle, the area is equal to half it's width times it's height,
so the equation is:
d = 21m/s * 8s / 2
∴d = 168m / 2
∴d = 84m.
So he traveled 84 meters in those 8 seconds, and probably scared
the bejeebers out of that poor deer.
Average speed = 21/2 m/s , Time =8 s, Distance = 8 x 21/2 =
84m
A plane traveling at 80 ms lands on a runway and comes to rest after 10 seconds What was the plane's deceleration
In the metric system the prefix for 1 1000 is
The trip took 317 days What was the average speed of the sailboat in miles per hour Round to the nearest tenth of a mile hour
We're missing a value, we'll need the distance traveled to
determine that.
120 meters northeast vector or scalar
Vector, magnitude and direction.
You drive a car 2 hours at 40 miles per hour 2 hours at 60 miles per hour how many miles will you travel
If you drive a car at 40 miles per hour for two hours,then the
distance covered will be 80 miles.If you drive the car for another
2 hours at 60 miles per hour ,then you will cover another 120
miles.The total distance you will cover is thus 80 miles + 120
miles = 200 miles.
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.
Which of these formulas is correctly rewritten from the original formula to solve for b a 3b - 2c
What is the tan of angle A bc equals 5 ca equals 12 ba equals 13
