An elevator starts from rest with a constant upward acceleration and moves 1 m in the first 1.7 s. A passenger in the elevator i
avanturin [10]

Answer: Tension = 53.6N

Explanation:

Given that

Height h = 1 m

Time t = 1.7 s.

Mass m = 5.1 kg 

From the equation of the motion we can get the acceleration of the elevator:

h = X0+ V0t + at2/2;

Th elevator starts from rest with a constant upward acceleration. Initial velocity Vo = 0, also Xo = 0; thus

a = 2h/t2 = 2 × 1/1.7^2

a = 0.69 m/s2.

Then we can find the tension in the cord by using the formula

T = mg + ma

= 5.1 (9.8 + 0.69)

= 5.1 × 10.5

= 53.6N

Vladimir [108]

Answer:

Move slowly and reach bottom later.

Explanation:

Viscosity is termed as the thickness or consistency of any liquid or semi liquid. It is related to the internal friction of the substance.

When several liquids are poured down with equal path lengths then the liquid will high viscosity will reach the bottom latter while one with less viscosity.

The internal friction of the molecules tends to keep them together making its consistency more thick. Thus when it will slope down from a certain height it will take more time to reach down.

Drupady [299]

Answer:

Explanation:

a )

Force at the surface = FR

Value of g at height h = g( 1 - 2 h / R )

force at height h = F_R ( 1 - 2 h / R)

F_R / 2 = F_R ( 1 - 2 h / R)

=  F_R   - 2  F_R xh / R

F_R / 2 = 2  F_R x h / R

1 / 2 = 2h / R

4h = R

h = R / 4 . Ans

b )

Value of g at depth  d = g( 1 -  d / R )

force at depth d  = F_R ( 1 - d / R)

F_R / 2 = F_R ( 1 - d / R)

=  F_R   -   F_R xd / R

F_R / 2 =   F_R x d / R

1 / 2 = d / R

2d  = R

d = R / 2
