Explanation:
I agree with Kathy gravity must be acting the same on both balls just because one ball is heavier doesn’t mean they will hit different times if the wooden ball was drop closer to the ground then the wooden ball would hit the ground first

How much longer would it take to travel a
distance of 600 km at a speed of 50 kmhr-1
than it would at a speed of 60 kmhr-1?
Explanation:
Time=distance/speed
=600/50
=12
=600/60=10
==12-10=2 hours

If the horizontal velocity component is 7.65 meters/second, what is the resultant velocity of the particle?
Answer:
R = 9.58 m/s
Explanation:
cos(37) = (7.65 m/s)/R
R = (7.65 m/s)/cos(37)
R = 9.58 m/s
A Red-Tailed Hawk leaves its nest and flies 100.0 meters across the sky in 20 seconds, when it spots a garter snake on the ground below. It then flies 50.0 meters in 5.0 seconds to catch the snake. What was the hawk's average speed over his entire journey?
Answer:
7.5 m/s
Explanation:
A red tailed hawk leaves its nest and flies 100 meters across the sky in 20 secs
Speed 1= distance/time
= 100/20
= 5m/s
When it spots a garter snake on the ground it flies 50 meters in 5 secs
Average speed= distance /time
= 50/5
= 10 m/s
Therefore the average speed of the hawk over the entire journey can be calculated as follows
= 10+5/2
= 15/2
= 7.5 m/s

How much resistance allows 6V battery to produce a current of 0.006 amps?
Answer:
It produces 1000Ω.
Explanation:
You have to apply Voltage formula, V = I × R :
V = I × R
6 = 0.006 × R
R = 6 ÷ 0.006
R = 1000Ω
We have that from the Question"How much resistance allows 6V battery to produce a current of 0.006 amps?" it can be said that How much resistance that allows 6V battery to produce a current of 0.006 amps is
R=1000 ohms
From the Question we are told
How much resistance allows 6V battery to produce a current of 0.006 amps?
Generally the equation for Resistance mathematically given as
[tex]R=\frac{V}{I}\\\\\Therefore\\\\R=\frac{V}{I}\\\\R=\frac{6}{0.006}\\\\[/tex]
R=1000 ohms
Therefore
How much resistance that allows 6V battery to produce a current of 0.006 amps is
R=1000 ohms

One of the largest pipe organs is in the auditorium organ in the Fox Theatre. The pipe is 32 ft. Long and produces a sound with a wavelength of about 8.8m. If the speed of sound in air is 346 m/s what is the frequency of this sound? What is the period? Show all work and explain your answer.
Explanation:
length of pipe= 32 ft
wavelength of wave λ= 8.8 m
let f be frequency
we know velocity of wave v=λf
therefore, f=v/λ = 346/8.8 = 39.31 per second or hertz
time period = 1/f = 1/39.31 = 0.02543 seconds
The frequency of this sound will be 39.31-sec⁻¹or Hz. While the time period will be 0.02543 sec.
What is the frequency?Frequency is defined as the number of repetitions of waves occurring in 1 second. Frequency is also defined as the number of cycles completed in 1 second. SI unit of frequency is Hz.
The given data in the problem is;
L is the length of pipe= 32 ft
λ is the wavelength of wave= 8.8 m
f is the frequency=?
T is the time period=?
The frequency is fine as the ratio of the speed of wave and wavelength.,
[tex]\rm f= \frac{v}{\lambda} \\\\ \rm f= \frac{346}{8.8}\\\\ \rm f= 39.31 \ Hz[/tex]
The time period is guven as the inverse of the time period.
[tex]\rm T = \frac{1}{f} \\\\ \rm T = \frac{1}{39.31} \\\\ \rm T = 0.02543\ sec[/tex]
Hence the frequency of this sound will be 39.31-sec⁻¹or Hz. While the time period will be 0.02543 sec.
