Answer:
D. Airplane wings must be designed to ensure that air molecules move more rapidly over the top surface of the wing, creating a region of lower pressure.
Explanation:
Bernoulli's theory operates on the assumption that its shape makes the air travel more over the top of the wing than under it as a plane moves through the air. Due to the pressure difference, wings feel a lifting force and create lift force. when pressure decrease than the velocity of the fluid will increase.
Therefore the answer is D.
That depends on WHERE the rig is, because
weight = (mass) x (acceleration of gravity where the object is) .
-- If the truck is on Mars, then
Weight = (36,000 kg) x (3.71² m/s²) = 133,560N.
-- If the truck is on the moon, then
Weight = (36,000 kg) x (1.62 m/s²) = 58,320N.
-- If the truck is on Earth, then
Weight = (36,000 kg) x (9.81 m/s²) = 353,160N.
It all depends.
Explanation:
neutron star, any of a class of extremely dense, compact stars thought to be composed primarily of neutrons. Neutron stars are typically about 20 km (12 miles) in diameter. Their masses range between 1.18 and 1.97 times that of the Sun, but most are 1.35 times that of the Sun.
