We can infer and logically deduce that the color of a boat's sternlight is white.

<h3>What is a sternlight?</h3>

A sternlight can be defined as a white light that is designed and developed to be placed as closely as possible and practical with the stern shining continuously (constantly).

By default, a sternlight is typically affixed to the boat in such a way that the light will shine out at an angle of 135 degrees (135°) from the back of the boat.

In this context, we can infer and logically deduce that the color of a boat's sternlight is white and it avails sailors and other persons the opportunity of determining and knowing the direction that a boat (vessel) is moving.

An elastic cable is to be designed for bungee jumping from a tower 130 ft high. The specifications call for the cable to be 85 f

azamat

Answer:

a) The spring constant is 50 lb/ft

b) The man is 26.3 ft close to the ground.

Explanation:

Height of tower is 130 ft

Specification calls for a cable of length 85 ft

the maximum this length stretches is 100 ft when subjected to a load of 750 lb

The extension of the cable is calculated from the formula from Hooke's law

F = kx

where F is the load or force on the cable

k is the spring constant of the cable

x is the extension on the cable

a) The extension on the cable is

x = 100 ft - 85 ft = 15 ft

substituting into the formula above, we'll have

750 = k*15

k = 750/15 = 50 lb/ft

b) for a 185 lb man, jumping down will give an extension gotten as

F = kx

185 = 50*x

x = 185/50 = 3.7 ft

The total length of the cable will be extended to 100 ft + 3.7 ft = 103.7 ft

closeness to the ground = 130 ft - 103.7 ft = 26.3 ft

An inventor claims to have developed a power cycle operating between hot and cold reservoirs at 1350 K and 295 K, respectively,

Art [367]

Answer:

efficiency = 0.71999 < 0.78148

efficiency = 0.7999 ≈ 0.78148

Explanation:

given data

Hot reservoir Temp Th = 1350 K

Cold reservoir Temp Tc = 295 K

heat transfer rate = 150,000 kJ/h

solution

first we get here maximum possible efficiency that is express as

maximum possible efficiency = 1 - $\frac{Tc}{Th}$ ..........1

put here value and we get

maximum possible efficiency = 1 - $\frac{295}{1350}$

maximum possible efficiency = 0.78148

and

efficiency = $\frac{Wout}{Qin}$ .................2

here Qin = $\frac{150000}{3600}$ = 41.667

so put here value in equation 2 we get

efficiency = $\frac{30}{41.667}$

efficiency = 0.71999 < 0.78148

and

efficiency = $\frac{33.33}{41.667}$

efficiency = 0.7999 ≈ 0.78148

claim might be true or not because there always be looser

Calculate the resistance of a lamp if the current through it is 0.4 A and the voltage across it is 8 V.

Papessa [141]

Answer:

Answer is 3.2 Ω (Ohms)

Explanation:

From Ohms Law I = V/R

R = V(I)

R = 8(0.4)

R = 3.2
