Chapter 34, Problem 20TE
If we can’t even predict the weather, how can we ever expect to predict the fate of the universe?
Expert Solution & Answer
To determine
The prediction of the fate of the universe.
Answer to Problem 20TE
There cannot be an exact theory about the fate of the universe, but the speculations can be made which can bring us closer to the fate of the universe.
Explanation of Solution
Indeed, we cannot predict the fate of the universe, but the continuous progress that scientists are making in the field of astronomy can help us getting closer to know the fate of the universe. As it is helped us to know why the universe is not collapsing but yet expanding due to dark energy. The behavior of dark energy is still unknown.
The speculations made by scientists are sophisticated speculations based upon the centuries of collected evidence. The powerful telescopes and many different missions to space, help in understanding the universe and the behavior of different energies.
Conclusion:
Therefore, there cannot be an exact theory about the fate of the universe, but the speculations can be made which can bring us closer to the fate of the universe.

The ramp has a slope angle of 20.0°, and the man pulls upward with a force F whose direction makes an angle of 30.0° 75.0° with the ramp (Fig. E4.4). (a) How large a force F is necessary for the component Fx parallel to the ramp to be 90.0 N? (b) How large will the component Fy perpendicular to the ramp be then?

The projectile lands on the tabletop a horizontal distance R (the "range") away from where it left the launcher. Set this up as a formal problem, and solve for vo (i.e., determine an expression for Vo in terms of only R, 0., and g). Your final equation will be called Equation 1.arrow_forward2. A projectile is shot from a launcher at an angle 0,, with an initial velocity magnitude vo, from a point even with a tabletop. The projectile hits an apple atop a child's noggin (see Figure 1). The apple is a height y above the tabletop, and a horizontal distance x from the launcher. Set this up as a formal problem, and solve for x. That is, determine an expression for x in terms of only v₁, o,y and g. Actually, this is quite a long expression. So, if you want, you can determine an expression for x in terms of v., 0., and time t, and determine another expression for timet (in terms of v., 0., y and g) that you will solve and then substitute the value of t into the expression for x. Your final equation(s) will be called Equation 3 (and Equation 4).arrow_forward
