Answer:
About 66 miles per hour
Explanation:
Based on the information given we can assume the car traveled the same number of miles every hour meaning all we need to do is divide.
400/6 ≈ 66 miles per hour
Answer
66 mph
Explanation:
400 ÷ 6 = 66.666666666666666.......

The tallest Ferris wheel in the world is located in Singapore. Standing 42 stories high and holding as many as 780 passengers, the Ferris wheel has a diameter of 150m and takes approximately 30 minutes to make a full circle. Determine the speed of the riders (in m/s) on the Singapore Flyer.
Answer:
The speed of the riders on the Singapore Flyer is approximately 0.262 m/s
Explanation:
The dimensions of the tallest Ferris wheel in the world are;
The diameter of the Ferris wheel, D = 150 m
The tine it takes the Ferris wheel to make a full circle, T = 30 minutes = 30 min × 60 s/min = 1,800 seconds
The angular velocity of the Ferris wheel, ω = 2·π/T
The linear velocity of the Ferris wheel, v = r·ω = The speed of the riders
Where;
r = The radius of the Ferris wheel = D/2
D = 150 m
∴ r = 150 m/2 = 75 m
∴ v = r·2·π/T
∴ v = 75 m × 2 × π/(1,800 s) ≈ 0.262 m/s
The speed of the riders on the Singapore Flyer, v ≈ 0.262 m/s
A bird flies South for the winter at a constant force of 51 N. Suddenly a wind with a force of 35 N blows due South. What is the net force of the bird?
Answer:
86N
Explanation:
The bird is going south and the wind is also blowing south so all the force is acting in the same direction thus it all adds up.

5.7 miles NE
Oh
9.1 miles sw
9.1 miles NE
Answer:
Explanation:
so her displacement is the distance from the start... she's now at a point (6,5) away from the start.. so what's the length of the side of the right triangle made by one side of 6 and the other of 5
Yes.. use Pythagoras theorem to solve this
C = √([tex]6^{2}[/tex]+[tex]5^{2}[/tex])
C = √(36 + 25)
C = √61
C = 7.810 miles.. north east of where she started
C = 7.8 miles NE :P

A sound wave is produced by a musical instrument for 0.40 second. If the frequency of the wave is 370 hertz, how many complete waves are produced in that time period? *
A) 200 waves
B)150 waves
C)100 waves
D) 50 waves
Explanation is in a file

The number of waves produced by the musical instrument during the given time is 148 waves.
What is meant by frequency of a wave ?Frequency of a wave is defined as the number of oscillations completed by the wave in one second.
Here,
The frequency of the wave, f = 370 Hz
That means the wave completes 370 oscillations in 1 second. Or 370 waves are produced by the musical instrument in 1 second.
The time taken by the instrument to produce waves, t = 0.4 s
Therefore,
The number of waves produced by the musical instrument during this time is,
n = f x t
n = 370 x 0.4
n = 148
Hence,
The number of waves produced by the musical instrument during the given time is 148 waves.
