Assuming no other horizontal force acts on the object, Calculate:(i)the resultant force

Answer»

Explanation:

Figure 1. Different forces exerted on the same mass produce different accelerations. (a) Two children push a wagon with a child in it. ARROWS representing all external forces are shown. The system of interest is the wagon and its rider. The weight W of the system and the support of the ground N are also shown for completeness and are assumed to cancel. The VECTOR f represents the friction acting on the wagon, and it acts to the left, opposing the motion of the wagon. (b) All of the external forces acting on the system add TOGETHER to produce a NET force, Fnet. The free-body diagram shows all of the forces acting on the system of interest. The dot represents the center of mass of the system. Each force vector extends from this dot. Because there are two forces acting to the right, we draw the vectors collinearly. (c) A larger net external force produces a larger acceleration (a′ > a) when an adult pushes the child.

The perimeter of a parallelogram is20 cm, its adjacent side are in the ratio3:2. Find the dimensions of theparallelogram.​

Answer»

Perimeter of parallelogram,

2(b+h) = 20cm

Ratio of the ADJACENT sides = 3:2

Let the sides be X say

Then, the ratio becomes to 3x:2x

As per problem,

  • 2(3x+2x) = 20cm
  • 2(5x) = 20cm
  • 10x = 20cm
  • x = 20cm/10
  • x = 2 cm

therefore, the value of x is 2cm

The adjacent sides,

  • 3x = 3×2cm = 6cm
  • 2x = 2×2cm = 4cm

Therefore, the adjacent sides are 6cm & 4cm

b) A 300 a wire Is stretched between 2 7 cm apart. If the tension in the wire is 10OR N. find C wie S Tirst, second, and third harmonic. Here R is your registration number.​

Answer»

ANSWER:

In fundamental mode ,

wavelength = 2 × Length of wire

Given,

MASS density = Mass of wire/length of wire = 3.5 × 10^-2/length of wire = 4 × 10^-2

Length of wire = 4/3.5 = 0.875 m

wavelength = 2 × length of wire

= 2 × 0.875 m

= 1.75 m

SPEED of WAVE = frequency × wavelength

= 45 × 1.75

= 78.75 m/s

Use formula,

Tension =( speed of wave)² × mass density

= (78.75)² × 4 × 10^-2

= 248.06 N

Answer»

ANSWER:

In other words, we can say that energy can neither be CREATED nor destroyed. In the CASE of a freely falling body, it is the mechanical energy of the system that is conserved. Mechanical energy (E) is the sum of the potential energy (U) and the KINETIC energy (K) of the freely falling body. Therefore, E=K+U=constant.
