<h2>Positive Affects:</h2>
  1. Technology aids in the research of curing diseases or other environmental problems. Without technology, we would not have been able to eradicate diseases like polio.
  2. Technology allows us to communicate to people quicker, in spite of the distance and conditions.
<h2>Negative</h2>
  1. Over-dependence of technology makes humans lazy. We won't be paying much attention because everything is available on Google.
  2. There are health affects due to the radiation. Our vision gets weakened and the laziness can lead to physical problems like obesity and fatigue.

Answer:

72 m

Explanation:

Given:

v₀ = 0 m/s

v = 60 m/s

a = 25 m/s²

Find: Δx

v² = v₀² + 2aΔx

(60 m/s)² = (0 m/s)² + 2 (25 m/s²) Δx

Δx = 72 m

What properties of sound determine the volume of sound?
Mila [183]
The amplitude of sound waves determines the volume of the sound. Not by the motion of sound, only pitch in that aspect. It is related to the square of the amplitude.

A marble slides without friction in a vertical loop around the inside of a smooth, 28.6 cm diameter horizontal pipe. The marble'
Leviafan [203]

Answer:3.49 m/s

Explanation:

Given

Speed of marble at Bottom v=4.22 m/s

Diameter of loop d=28.6 cm

As Energy is conserved therefore Energy at top is equal to energy at bottom

E_T=E_B

\frac{mv^2}{2}+mgh=\frac{mv_0^2}{2}  ,where v_0 is the velocity at bottom

\frac{v^2}{2}+gh=\frac{v_0^2}{2}

v_0^2=v^2+2gh

v^2=v_0^2-2gh

v=\sqrt{v_0^2-2gh}

v=\sqrt{4.22^2-2\times 9.8\times 0.286}

v=\sqrt{17.8084-5.6056}

v=3.49 m/s
