An athlete whirls a 7.00 kg hammer 1.8 m from the axis of rotation in a horizontal circle, as
shown in the figure below. The hammer makes one revolution in 1.0 s. What is the tension in
the chain?
A-500 N
B-50 N
C-5000 N
D-5 N
Answers
Answer:
A-500 N
Explanation:
The computation of the tension in the chain is shown below
As we know that
F = ma
where
F denotes force
m denotes mass = 7
And, a denotes acceleration
Now for the acceleration we have to do the following calculations
The speed (v) of the hammer is
v = Angular speed × radius
where,
Angular seed = 2 × π ÷ Time Period
So, v = 2 × π × r ÷ P
v = 2 × 3.14 × 1.8 ÷ 1
= 11.304 m/s
Now
a = v^2 ÷ r
= 70.98912 m/s^2
Now the tension is
T = F = m × a
= 7 × 70.98912
= 496.92384 N
= 500 N

b. 0.375 to 3 meters
c. 2,000 to 5,500 meters
d. 0.33 to 2.66 meters
Answers
With the use of wave speed formula, below are the answers to the questions
1. C
2. C
3. D
4. B
All the question centered on wave speed, wavelength and wave frequency. The relationship between these three quantities is;
wave speed = wavelength x frequency
That is,
V = Fλ
1. The given parameters are;
V = 1,500 m/s
F = 5 Hz
wavelength λ = V/F = 1500/5 = 300 m
2.) Given that the wavelengths ranging from 2.75 to 16.5 meters and the speed of sound is approximately 330 m/s
When wavelength = 2.75 m
F = V/ λ = 330 / 2.75 = 120 Hz
When wavelength = 16.5 m
F = V/ λ = 330 / 16.5 = 20 Hz
Therefore, the frequencies of thunder humans hear ranges from 20 Hz to 120 Hz
3.) Since the two waves are similar, they will be travelling at the same speed. That is,
Wave speed of X = Wave speed of Y
For wave X and Y respectively;
F = 200 Hz and 700 Hz
λ = 35 m and λm
Find λ of Y by equating the two wave speed. That is,
Fλ for X = Fλ for Y
200 x 35 = 700 λ
λ = (200 x 35)/ 700
λ = 7000 / 700
λ = 10 m
Therefore, The wavelength for wave Y is 10 m
4.) Given that the sea lions frequencies are ranging from 500 to 4,000 hertz. And the speed of sound in sea water is approximately 1,500 m/s
By using the same formula,
V = Fλ
Make wavelength the subject of formula
λ = V / F
When F = 500 Hz
λ = 1500/500 = 3 m
When F = 4000 Hz
λ = 1500/4000 = 0.375 m
Therefore, the approximate wavelengths of sound with which the California sea lions communicate is of the range 0.375 m to 3 m

Hernando builds a simple DC series circuit with a standard D-cell battery and uses an ammeter to determine that the total current in the system is 3.0 A. In an attempt to increase the brightness of the bulbs in the circuit, he tries to increase the voltage by adding two more batteries (in series with the first). Calculate the new current when driven by three batteries.
Answers
Answer: I = 9.0 A
Explanation: Ohm's Law is defined as the relationship between voltage and current: in a circuit, the voltage accross a conductor is directly proportional to the current.
The constant of proportionality is Resistance, whose unit is ohm (Ω).
so, Ohm's Law is
V = R.I
It is asked for the current, so, rearraging:
[tex]I=\frac{V}{R}[/tex]
When added two more batteries, the voltage of the circuit triples:
[tex]V_{final}=3V_{initial}[/tex]
Since they are directly proportional, if voltage triples, so does current:
[tex]I_{final}=3I_{initial}[/tex]
[tex]I_{final}=3(3.0)[/tex]
[tex]I_{final}=[/tex] 9.0
The new current, when driven by 3 batteries is 9.0 A.

If dan ran the 100m dash in 10.23s. What was his average speed during the race? (Round to the nearest tenth of a second)
Answers
Answer:
.1 seconds per meter
Explanation:
I am going to assume they are asking for the average time per 1 meter.
Because it took 10.23 seconds to run 100 meters, we are going to divide 10.23 by 100. This number will be the time per 1 meter.
To divide by 100, we will move the decimal point over by two. That will give us .1023 seconds.
The question asks to round to the nearest tenth, so we round it to .1 seconds.
*Just some trivia: Danie van Blerk does in fact have a time of 10.23 seconds. He has the 1073rd best 100 meter dash time. First place, Usain Bolt, has a time of 9.58 seconds.
