Penelope sees that her brother Angelos is using water carelessly. She warns Angelos to be more careful because water is a renewa

ble resource and can be used up since it takes millions of years to form. Angelos argues that water is a nonrenewable resource and cannot be used up since it can be replaced when it rains.
Which statement is best supported by this scenario?

A. Penelope was correct when she said that water takes millions of years to form.
B. Penelope was correct when she said that water can be used up.
C. Angelos was correct when he said that water is a nonrenewable resource.
D. Angelos was correct when he said that water cannot be used up.

Correct option: B

The water is a precious resource as it is used everywhere. Once we use the water it becomes dirty or unusable and can only be recycled by snow melting or rainfall. Clean water can get used up and it can only be replenished by rain or snow melting. Hence, Penelope was correct when she said that water (clean) can be used up. If you use water for washing, cleaning and other industrial purposes, it becomes dirty and you cannot reuse it. Hence, you have to wait for rain to get clean water again. Hence, the clean water can be used up.

A flywheel with a diameter of 1.63 m is rotating at an angular speed of 79.9 rev/min. (a) What is the angular speed of the flywh
Studentka2010 [4]

Answer:

(a) 8.362 rad/sec

(b) 6.815 m/sec

(c) 9.446 rad/sec^2

(d) 396.22 revolution

Explanation:

We have given that diameter d = 1.63 m

So radius r=\frac{d}{2}=\frac{1.63}{2}=0.815m

Angular speed N = 79.9 rev/min

(a) We know that angular speed in radian per sec

\omega =\frac{2\pi N}{60}=\frac{2\times 3.14\times 79.9}{60}=8.362rad/sec

(b) We know that linear speed is given by

v=r\omega =0.815\times 8.362=6.815m/sec

(c) We have given final angular velocity \omega _f=675rev/min

And \omega _i=79.9rev/min

Time t = 63 sec

Angular acceleration is given by \alpha =\frac{\omega _f-\omega _i}{t}=\frac{675-79.9}{63}=9.446rad/sec^2

(d) Change in angle is given by

\Theta =\frac{1}{2}(\omega _i+\omega _f)t=\frac{1}{2}(675+79.9)\times 1.05=396.22rev

inysia [295]

Answer:

Best explains Jamming

Explanation:

<em>The deliberate radiation of electromagnetic (EM) energy to degrade or neutralize the radio frequency long-haul supervisory control and data acquisition (SCADA) communications links, best explains what?</em>

Jamming is defined as the blocking or interference with authorized wireless communications. it's a problem  in personal area network wireless technologies. Jamming can occur inadvertently due to high levels of noise .

Jammers can send radio signals to interfere or disrupt communication flows by by decreasing the signal-to-noise ratio.They use radio frequency to interfere with communications by keeping it busy.
