Answer:

The tension on each rope is 28.28 lb

Explanation:

Given that,

Weight = 40 lb

Angle = 45°

We need to calculate the tension on each rope

Considering the symmetry of the system, the tension of each rope must be same

So,

T\sin\theta+T\sin\theta=mg

Put the value into the formula

2T\sin\theta=mg

T\times\sin45=\dfrac{40}{2}

T=\dfrac{40\sqrt{2}}{2}

T=28.28\ lb

Hence, The tension on each rope is 28.28 lb.

SVETLANKA909090 [29]
The correct answer is B. Fuse.

Fuses were commonly used in houses up to recent ages, when circuit breakers became the more popular options, as they don't have to be changed every time they melt, since they don't melt.

Which air mass provides the moisture that produces the clouds and precipitation?
Andreas93 [3]
The MT is the air mass that provides the moisture that produces the clouds and precipitation. An air mass is a volume of air that is defined by its temperature and water vapor or moisture content .  MT is the abbreviation of marine time air mass. Air masses can control the weather for a relatively long time period from a period of days, to months, Most weather occurs along the periphery of these air masses at boundaries called fronts.

Otrada [13]

Hi there!

For this part, we can disregard the horizontal velocity because horizontal and vertical motion are INDEPENDENT.

We can used the simplified equation to solve for time:

t = \sqrt{\frac{2h}{g}}

Where:

h = height

g = acceleration due to gravity (assume g = 10 m/s²)

Plug in given values:

t = \sqrt{\frac{2(50)}{10}} = \sqrt{10}

t ≈3.162 sec
