Answer:

Tension= 4,373.70N

Explanation:

Ma= Sum of forces

Horizontal forces are:

0= T1costheta=T2costheta

T1=T2=T

Vertical forces are:

Ma= T1sin8°+ T2sin8° - mg

Ma= 2Tsin8° - mg

Therefore ,

T= m(a+g)/(2sin8°)

T= 68(8.10+9.8)/2×0.139

68(17.9)/0.2783

T= 4373.697

T= 4373.70N

Describe a sea-level transgression
Eduardwww [97]
<span>Some geographic areas endure cycles between these two processes called transgressive-regressive sequences. The rocks of western Pennsylvania are one example. Sandy beaches often leave observable records of transgression by covering marsh sediments that were once behind it as it moves inland. The original sediments are then covered by even deeper water sediments, which geologists can trace and record. It is generally believed that transgression will increase in accordance with rising sea levels worldwide</span>

Why is radiation fog more likely near the center of an anticyclone than near the center of a cyclone?
Zigmanuir [339]
Radiation fog is the fog that is formed when the heat absorbed the Earth's surface is released into the atmosphere producing fog. This only occurs when the air is clear and calm. In the center of an anticyclone, the conditions of the air are clear and calm which is favorable for the formation of radiation fog. The center of cyclones, on the other hand, is turbulent and cloudy which prevents the formation of radiation fogs.
