Use the definition of scalar product, a with arrow · b with arrow = ab cos θ, and the fact that a with arrow · b with arrow = ax

bx + ayby + azbz to calculate the angle between the two vectors given by a with arrow = 5.0i hat + 5.0j + 4.0k and b with arrow = 6.0i hat + 3.0j + 5.0k.

7. A beam of light converges at a point P. Now a lens is placed in the path of the convergent
Rudiy27

Answer:

Lens at a distance = 7.5 cm

Lens at a distance = 6.86 cm  (Approx)

Explanation:

Given:

Object distance u = 12 cm

a) Focal length = 20 cm

b) Focal length = 16 cm

Computation:

a. 1/v = 1/u + 1/f

1/v = 1/20 + 1/12

v = 7.5 cm

Lens at a distance = 7.5 cm

b.  1/v = 1/u + 1/f

1/v = 1/16 + 1/12

v = 6.86 cm  (Approx)

Lens at a distance = 6.86 cm  (Approx)

A 77.0 kg rider sitting on a 7.3 kg bike is riding along at 9.3 m/s in the positive direction. The rider drags a foot on the gro
saw5 [17]

Answer with Explanation:

We are given that

Mass of rider=m=77 kg

Mass of bike =m'=7.3 kg

Initial velocity,u=9.3 m/s

Final velocity,v=6 m/s

A.Change in velocity=v-u=6-9.3=-3.3 m/s

Total mass,M=m+m'=77+7.3=84.3 kg

Change in momentum=M(v-u)=84.3(-3.3)=-278.19 kgm/s

B.Impulse=Ft=Change in momentum=-278.19kg m/s

C.Time,t=13.2 s

v=u+at

Using the formula

6=9.3+13.2a

13.2a=6-9.3=-3.3

a=-\frac{3.3}{13.2}=-0.25 ms^{-2}

F=ma

F=84.3(-0.25)=-21.075 N

D.S=ut+\frac{1}{2}at^2

S=9.3(13.2)+\frac{1}{2}(-0.25)(13.2)^2

S=100.98 m
