Answer to Problem 1QP

Option (d)

Explanation of Solution

According to Einstein's theory of General Relativity, space itself can be considered to be, cured by mass. As a result, the density of the universe can find how much mass it has spread over to its volume, to determine its shape, as well as its future.

The critical density is proportional to the square of the Hubble constant, which is used in measuring the expansion rate of the universe.

Comparing the critical density to the actual density can help scientists to understand the cosmos.

Conclusion:

The density of the universe dictates whether it will be open, closed, or flat. Therefore, option (d) is correct.

The density of the universe dictates whether it will be open, closed, or flat. Therefore, option (a) is incorrect.

The density of the universe dictates whether it will be open, closed, or flat. Therefore, option (b) is incorrect.

The density of the universe dictates whether it will be open, closed, or flat. Therefore, option (c) is incorrect.

If the room’s radius is 16.2 m, at what minimum linear speed does Quicksilver need to run to stay on the walls without sliding down?  Assume the coefficient of friction between Quicksilver and the wall is 0.236.
In the comics Thor flies by spinning his hammer really fast from a leather strap at the end of the handle, letting go, then grabbing it and having it pull him. If Thor wants to reach escape velocity (velocity needed to leave Earth’s atmosphere), he will need the linear velocity of the center of mass of the hammer to be 11,200 m/s. A) If the distance from the end of the strap to the center of the hammer is 0.334 m, what angular velocity does Thor need to spin his hammer at to reach escape velocity? b) If the hammer starts from rest what angular acceleration does Thor need to reach that angular velocity in 4.16 s? c) While the hammer is spinning at its maximum speed what impossibly large tension does the leather strap, which the hammer is spinning by, exert when the hammer is at its lowest point? The hammer has a total mass of 20.0kg.
The car goes from driving straight to spinning at 10.6 rev/min in 0.257 s with a radius of 12.2 m. The angular accleration is 4.28 rad/s^2. During this flip Barbie stays firmly seated in the car’s seat. Barbie has a mass of 58.0 kg, what is her normal force at the top of the loop?
