Answer:

F = 0.64 N

Explanation:

We are given;

Spring constant constant; k = 1.28 N/m

Distance; x = 0.5 m

From Hooke's law, we know that F = kx.

Thus;

F = 1.28 × 0.5

F = 0.64 N

Thus, force it takes to pull the spring back = 0.64 N

Which of the following describe circumstances under which an exculpatory clause is generally unenforceable? Select all that appl
Sveta_85 [38]

Answer:

a. When the parties have unequal bargaining power  

c. When it covers public transportation  

Explanation:

Exculpatory clauses are often found in agreements between a company and a consumer when the activity is in danger, such as at a fitness center or ski resort. The company wants the consumer to understand the risk involved and to avoid lawsuits, so it includes a disclaimer in its contract. These clauses are used to limit liability, so they are not enforced when the parties have unequal bargaining power and when covering public transport.

A ski tow operates on a slope of angle 15.6 ∘ of length 340 m . The rope moves at a speed of 12.7 km/h and provides power for 53
GREYUIT [131]

Answer:

P = 34034.2 Watt

Explanation:

As we know that the slope angle is given as

\theta = 15.6^0

now the weight of the rider along the slope is given as

W = mgsin\theta

W = 69(9.81)sin15.6

W = 182 N

now total weight of all 53 riders along the slope is given as

F = 53 W

F = 9647.5 N

now the speed of the rope is given as

v = 12.7 km/h = 3.53 m/s

now the power required is given as

P = F.v

P = 9647.5(3.53)

P = 34034.2 Watt
