If the direction of both r and fare reversed ,the direction of momentum force |
|
Answer» You should DEFINE your variables. I think we all know that F is a vector pointing in the direction of the force. HOWEVER, R is typically not the variable used for a vector in this situation (typically r is used), and r refers to the vector from the axis to the point where the Force is applied - therefore “reversing the direction of R” confuses the issue. However, it is clear that the torque is given by the vector equation, torque = r X F. The magnitude of the torque will not change if the directions of either or both of r and F is reversed |

|
Answer» ✔️ Answer ✔️ Your answer:- Check out the ATTACHMENT please. What is an inclined plane? Inclined plane, SIMPLE machine consisting of a sloping surface, used for raising heavy bodies. The force required to move an object up the INCLINE is less than the weight being RAISED, discounting friction. The steeper the slope, or incline, the more NEARLY the required force approaches the actual weight. #KEEPLEARNING HOPE I AM CLEAR. WARM REGARDS. (≧▽≦) |

Answer» An optical fiber (or fibre in British English) is a flexible, TRANSPARENT fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair.[1] Optical fibers are used most often as a means to TRANSMIT light[a] between the two ends of the fiber and find WIDE usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data transfer rates) than electrical cables. Fibers are used instead of metal wires because signals travel along them with less loss; in addition, fibers are immune to electromagnetic interference, a problem from which metal wires suffer.[2] Fibers are also used for ILLUMINATION and imaging, and are often wrapped in bundles so they may be used to carry light into, or images out of confined spaces, as in the case of a fiberscope.[3] Specially designed fibers are also used for a variety of other applications, some of them being fiber optic sensors and fiber lasers |

Can proofs of equations os motion be asked in exams in class 9?For example those V = U + AT proofs |
|
Answer» Answer: where u = initial velocity, v = final velocity, a = ACCELERATION and t = TIME period Explanation: We KNOW acceleration (a) = rate of change of velocity
= timeinterval changeinvelocity
= timeperiod finalvelocity−initialvelocity
= t v−u
∴a= t v−u
ora×t=v−u or at = v - u or at + u = v ∴ v = u + at |

Diameter of the metal ball measured by vernier caliper is 2.34 cm. if least count of vernier is 0.01 cm, calculate percentage error. |
Answer» Given:-
⠀ To FIND:-
⠀ Solution:-→ Percentage error = FRACTIONAL error × 100 → Fractional error = Absolute value ÷ Measured values → Fractional error = 0.01 ÷ 2.34 → Fractional error = 0.00427 Now, → Percentage Uncertainty = Fractional error × 100 → Percentage Uncertainty = 0.00427 × 100 → Percentage Uncertainty = 0.427% ⠀ Hence,

What is a blue hole?( people are really worse , they report my relevant and educational questions+Answers alsoಥ╭╮ಥ) |
|
Answer» Answer: A blue hole is a large marine CAVERN or sinkhole, which is open to the surface and has DEVELOPED in a bank or island composed of a carbonate bedrock. Their existence was first discovered in the late 20th CENTURY by fishermen and recreational divers. The Blue Hole itself is no more dangerous than any other Red Sea dive site but diving through the Arch, a submerged tunnel, which lies within the Blue Hole site, is an extreme dive that has RESULTED in many accidents and fatalities. Most blue holes are formed from sinkholes or caves that develop slowly over time, as rock begins to erode and collapse. Many blue holes were formed during the last Ice Age, after sea levels rose and filled existing sinkholes with water. Take care |
