## What is parallelogram law of vectors explain with examples?

If two vectors are acting simultaneously at a point, then it can be represented both in magnitude and direction by the adjacent sides drawn from a point. Therefore, the resultant vector is completely represented both in direction and magnitude by the diagonal of the parallelogram passing through the point.

**What are vector quantities 20 examples?**

Some examples of vector quantities include:

- force, eg 20 newtons (N) to the left.
- displacement, eg 50 kilometres (km) east.
- velocity, eg 11 metres per second (m/s) upwards.
- acceleration, eg 9.8 metres per second squared (m/s²) downwards.
- momentum, eg 250 kilogram metres per second (kg m/s) south west.

**Is the working of a sling an example of parallelogram law?**

Yes, the sling based on parallelogram law of vector. The sling consist of two two rubber strings AO and BO which are attached with Y-shaped wooden frame. When a stone is held at point O and the junction of the two string on the rubber band is pulled, then the tension T1 and T2 are produced along OA and OB.

### What is the parallelogram law in physics?

: a law in physics: the resultant of two vector quantities represented in magnitude, direction, and sense by two adjacent sides of a parallelogram both of which are directed toward or away from their point of intersection is the diagonal of the parallelogram through that point.

**What is the formula of parallelogram law?**

According to the parallelogram law of vector addition if two vectors act along two adjacent sides of a parallelogram(having magnitude equal to the length of the sides) both pointing away from the common vertex, then the resultant is represented by the diagonal of the parallelogram passing through the same common vertex …

**What is the use of parallelogram law of forces?**

a rule for adding two vectors, as forces (parallelogram of forces ), by placing the point of application of one at the point of origin of the other and obtaining their sum by constructing the line connecting the two remaining end points, the sum being the diagonal of the parallelogram whose adjacent sides are the two …

#### What is the specific example of a vector?

For example, displacement, velocity, and acceleration are vector quantities, while speed (the magnitude of velocity), time, and mass are scalars. To qualify as a vector, a quantity having magnitude and direction must also obey certain rules of combination.

**What are vector quantities 5 examples?**

Other examples of vector quantities are displacement, acceleration, force, momentum, weight, the velocity of light, a gravitational field, current, and so on.

**What is the parallelogram law of vector addition?**

The parallelogram rule says that if we place two vectors so they have the same initial point, and then complete the vectors into a parallelogram, then the sum of the vectors is the directed diagonal that starts at the same point as the vectors.

## Is the working of a slingshot is based on the parallelogram law of vector addition explain?

Answer. Yes, the sling based onparallelogram law of vector. According to parallelogram law of forces, the resultant tension T of the two tensions act on the stone along OC. As the stone is released, it shoots under the action of resultant tension T in forward direction.

**What is the parallelogram method?**

The Parallelogram Method The parallelogram method is a little more difficult to describe, but is just as easy in practice as the head-to-tail method. The best way to understand this method is to see it performed visually.

**How do you calculate specific heat in physics?**

Get the huge list of Physics Formulas here. Specific Heat Formula. As we discussed above the specific heat is the relation of temperature change of an object with water. Also, the formula is like this: Heat energy = (mass of the object or substance) × (specific heat) × (Change in temperature) Q = m × c × \\(\\Delta T\\) Or. Q = \\(mc\\Delta T\\)

### What is specific heat and how to use it?

But, specific heat is a concept that very few people know about. Also, we use specific heat to raise the temperature of an object by degree. In addition, we will discuss specific heat, specific heat formula, its derivation and solved examples in this topic.

**What is the specific heat in joules/G°C?**

What is the specific heat in Joules/g·°C? The specific heat of copper is 0.39 J/g·°C. Helmenstine, Todd. “Specific Heat Example Problem.” ThoughtCo, Aug. 27, 2020, thoughtco.com/specific-heat-example-problem-609531. Helmenstine, Todd. (2020, August 27). Specific Heat Example Problem.
