Why does the total weight of the shuttle decrease during the first 20 seconds?
The total weight of the shuttle decreases during the first 20 seconds of flight because the shuttle is burning fuel, which is released as exhaust gases. As fuel is burned, the weight of the shuttle decreases due to the loss of mass from the system.
What is the decrease in weight caused by the upward force of displaced fluid?
It is named after Archimedes of Syracuse, who first discovered this law. According to Archimedes' Principle, "any body fully or partially submerged in a fluid is buoyed up by a force equal to the weight of the fluid displaced." When a body is fully immersed the weight of fluid displaced is equal to the volume of the body times the density of the fluid. So this amount will be the reduction in apparent weight of the body. If the body is floating, its apparent weight is reduced to zero, so the weight of fluid displaced must equal the weight of the body. In this case only part of the volume of the body needs to be immersed to displace its weight in fluid, because the body has a lower density than the fluid.
How many second did the wright brother's first flight last?
The Wright Brothers' first powered flight on December 17, 1903, lasted 12 seconds and covered a distance of 120 feet.
What is the distance that the object travels in the first 5 seconds?
To find the distance traveled in the first 5 seconds, we multiply the average velocity by the time traveled. If the object's velocity is constant, this distance is equal to the velocity multiplied by the time.
How would you measure the weight of your dog?
To measure the weight of your dog, use a bathroom scale. Step on the scale alone first to record your weight, then pick up your dog and step on the scale again. The difference in weight between the two readings will be your dog's weight.
Why does the total weight of the shuttle decrease during the first 20 seconds?
The total weight of the shuttle decreases during the first 20 seconds of flight because the shuttle is burning fuel, which is released as exhaust gases. As fuel is burned, the weight of the shuttle decreases due to the loss of mass from the system.
