An influence upon an oscillatory system that has the effect of reducing/restriction or preventing its oscillations. Damping is produced by processes that dissipate the energy stored in the oscillation.
Answer:
Static friction prevents the motion of an object while sliding friction is a type of frictional motion between two surfaces in contact.
Explanation:
Answer:
![4 ms^{-2}](https://tex.z-dn.net/?f=4%20ms%5E%7B-2%7D)
Explanation:
Normal force - should be the reaction from the surface it's on - nullifies the weight of the object. At this point the only force is of
from whoever is pushing the square and the friction, towards the right. At this point we divide the force by the mass of the object to obtain an acceleration of ![8/2 = 4 ms^{-2}](https://tex.z-dn.net/?f=8%2F2%20%3D%204%20ms%5E%7B-2%7D)
The object will fall through a distance of 638.45 m.
Considering the question given above, the following data were obtained:
Time (t) = 11.3 s
<h3>Height (h) =? </h3>
<u>NOTE</u>: Acceleration due to gravity (g) = 10 m/s²
We can obtain the height as illustrated below:
H = ½gt²
H = ½ × 10 × 11.3²
H = 5 × 127.69
<h3>H = 638.45 m</h3>
Therefore, the distance the object will fall is 638.45 m

Answer: 28
Explanation:
Given
Circuit breaker current is ![I=20\ A](https://tex.z-dn.net/?f=I%3D20%5C%20A)
Power of the light bulb is ![P=100\ W](https://tex.z-dn.net/?f=P%3D100%5C%20W)
Voltage of the DC-circuit is ![V=120\ V](https://tex.z-dn.net/?f=V%3D120%5C%20V)
If the resistance are connected in parallel, they must have same voltage i.e. 120 V
So, Resistance is given by
![\Rightarrow R=\dfrac{V^2}{P}\\\\\Rightarrow R=\dfrac{120^2}{100}\\\\\Rightarrow R=144\ \Omega](https://tex.z-dn.net/?f=%5CRightarrow%20R%3D%5Cdfrac%7BV%5E2%7D%7BP%7D%5C%5C%5C%5C%5CRightarrow%20R%3D%5Cdfrac%7B120%5E2%7D%7B100%7D%5C%5C%5C%5C%5CRightarrow%20R%3D144%5C%20%5COmega)
For the 20 A current and 120 V battery, net resistance is
![\Rightarrow R_{net}=\dfrac{120}{20}\\\\\Rightarrow R_{net}=6\ \Omega](https://tex.z-dn.net/?f=%5CRightarrow%20R_%7Bnet%7D%3D%5Cdfrac%7B120%7D%7B20%7D%5C%5C%5C%5C%5CRightarrow%20R_%7Bnet%7D%3D6%5C%20%5COmega)
Suppose there are n resistance in the circuit connected in parallel.
![\Rightarrow \dfrac{144}{n}=R_{net}\\\\\Rightarrow n=\dfrac{144}{6}\\\\\Rightarrow n=28.8\approx 28\ \text{for current to be less than 20A}](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cdfrac%7B144%7D%7Bn%7D%3DR_%7Bnet%7D%5C%5C%5C%5C%5CRightarrow%20n%3D%5Cdfrac%7B144%7D%7B6%7D%5C%5C%5C%5C%5CRightarrow%20n%3D28.8%5Capprox%2028%5C%20%5Ctext%7Bfor%20current%20to%20be%20less%20than%2020A%7D)
Thus, there can maximum of 28 bulbs.
