Answer:
Young's modulus of this tendon is .
Explanation:
Given that,
Length of the tendon, l = 19 cm
It is stretched by 4.5 mm,
Force, F = 11.3 N
Average diameter, d = 8.2 mm
Radius, r = 4.1 mm
The formula of Young's modulus of this tendon is given by :
So, the Young's modulus of this tendon is . Hence, this is the required solution.
Answer:
Explanation:
Given that,
Mass m = 2kg
Initial Velocity Vi = 3m/s
Force applied. = 4N
Distance cause by the force applied d = 5m
a. Work done by the force applied?
Work done by force applied can be determined by
W = F×d•Cosx
Where x is direction is the force and displacement
The force and displacement are in the same direction, then, x =0°
W = F×d•Cosx
W = 4×5Cos0
W = 20J.
b. Final velocity
The change in kinetic energy is equal to work done
∆K.E = W
½mVf² - ½mVi² = W
½mVf² = ½mVi² + W
½ × 2 Vf² = ½ × 2 × 3² + 20
Vf² = 9+20
Vf² = 29
Vf = √29
Vf = 5.39m/s
The final velocity is 5.39m/s
Answer:
Lateral inversion
Explanation:
When an object is placed in front of a plane mirror, the appearance of the object on the plane mirror appears as a reversal of the object. This effect is known as lateral inversion.
Lateral inversion occurs as a result of the fact that light is reflected by a plane mirror. The image formed by the plane mirror is as far behind the mirror as the object is in front of it. Hence lateral inversion occurs because of the way our brains perceive images on a plane mirror. The mirror image of symmetrical letters and objects do not show lateral inversion.
