One of the flaws in the engineers' reasoning for galloping gertie's design was that they attributed prior failures of suspension bridges to too much weight or poor workmanship.
True or false
At the coast on a summer day, the land is hotter than the ocean. Warm air over the land rises and is replaced by cooler air, causing a sea breeze.
At night, the land cools quickly and the ocean is now warmer than the land. What will happen next?
Winds will stop blowing as the convection current ceases to flow.
The convection current will reverse direction, reversing the winds.
Winds will increase as the two convection currents overlap.
The convection current will move seaward, reversing the winds.

The convection current will reverse direction, reversing the winds. The correct option is 2.
What is convection current?A convection current is a fluid motion caused by the uneven heating of a fluid, such as air or water.
During the day, the land heats up faster than the ocean, causing warm air to rise and cool air from above to replace it. As a result, a sea breeze blows from the ocean to the land.
The land cools faster than the ocean at night, causing the opposite effect. Because the air over the ocean is warmer than the air over land, the convection current reverses direction.
Warm air rising from the ocean is replaced by cool air rising from the land. This causes a land breeze to blow from the land to the ocean, reversing the wind direction.
Thus, the correct option is 2.

What are some facts about Explorer IV spacecraft?
I don't need long sentences.
Answer:
-launched on July 26, 1958
-the mission remained secret from the public for six months
-was designed to further investigate the radiation belt around Earth
-the mission lasted 71 days
Explanation:
Answer:
Explorer 4 was identical in size to the earlier Explorers but was over 3 kg heavier, primarily due to a larger instrument payload. The satellite was a 2.03 m long, 0.15 m diameter cylinder and nosecone that comprised the fourth stage of the Jupiter-C launch vehicle. The on-orbit mass (after fuel burnout) was 17.43 kg. The spacecraft body was made of stainless AISI-410 steel, 0.058 cm thick. The surface was sandblasted, no aluminum oxide striping was used as on earlier Explorers.
Explanation:
Explain the prosses of welding
Answer:
Welding is a fabrication process whereby two or more parts are fused together by means of heat, pressure or both forming a join as the parts cool. Welding is usually used on metals and thermoplastics but can also be used on wood.
