Two forces are in the ratio of 7:5. The maximum and minimum of their resultants are in the ratio of (A) 5:2 (B) 2:5 (C) 6:1 (D)1:6 answer please |
|
Answer» aximum and MINIMUM of their RESULTANTS are in the ratio of 6:1. Option C) ✬Step-by-step explanation:Given:-TWO forces are in the ratio of 7:5.To find:-The maximum and minimum resultant of the force Required FORMULA:-F_max = F₁ + F₂F_min = F₁ - F₂Solution:-Where,F₁ = 7F₂ = 5Applying the values,The maximum resulant of the force is 12. Finding the minimum resultant of the force,The minimum resultant of the force is 2. Now,Finding the force of maximum and minimum resultant.Therefore,The maximum and minimum resultant of the force is 6:1. |

>define average velocity. >Don't answer irrelevant answers. >Correct Answer = Brainliest. |
|
Answer» tion:The AVERAGE velocity of an object is its total DISPLACEMENT divided by the total time taken. In other words, it is the rate at which an object changes its position from one place to another. Average velocity is a vector quantity. The SI UNIT is meters PER second. |
|

How do you get the displacement of a particle is a straight line. show that its speed is constant? |
|
Answer» placement of a particle MOVING in a straight LINE is the change in its POSITION. If the particle moves from the position x(T1) to the position x(t2), then its displacement is x(t2)−x(t1) over the time interval [t1,t2]. In PARTICULAR, the position of a particle is its displacement from the origin.Hope it's helpful.♥ |

If object distance and image distance from a concave mirror is S° and Si respectively and R is the radius of curvature, if f= R/2, what is the mirror equation |
|
Answer» 1) In thermodynamics, an isothermal process is a type of thermodynamic process in which the temperature of the system remains constant: ΔT = 0. In contrast, an adiabatic process is where a system exchanges no heat with its surroundings (Q = 0).2) In physics (specifically, celestial mechanics), escape velocity is the minimum SPEED needed for a FREE, non-propelled OBJECT to escape from the gravitational influence of a massive body, that is, to eventually REACH an infinite distance from it.Hope it will helps ✌ |
