2. Starting from rest, a racecar has a displacement of 201 m south while accelerating at
16 m/s?. Calculate the time it takes the car to travel the 201 m.
Help solve please!
Answer:
Explanation:
Assuming you mean a = 16 m/s²
s = ½at²
t = √(2s/a)
t = √(2(201)/16)
t = 5.012484...
t = 5.0 s
Which of the following is a true statement about computational models?
1. Computational models are more objective than humans, so computational models can be used to minimize bias.
2. Computers carry out the exact instructions you give them, whether they are the correct instructions or not.
3. Computational models, especially ones on computers with strong computational power, can fix errors in inputted equations.
4. Most computers have limits to computational power, with the exception of supercomputers.
The true statement about computational models is: 2. Computers carry out the exact instructions you give them, whether they are the correct instructions or not.
A computational model can be defined as the systematic use of computers to simulate real-complex systems, as well as studying them through the algorithmic or mechanistic use of various fields in science such as:
Mathematics.Computer science.Physics.A computer refers to an electronic device that is designed and developed to receive data (instructions) in raw form as an input, and then processes these data into an information (output) that is usable by an end user.
Generally, computers are designed to carry out the exact instructions an end user gives to them, whether those instructions are correct (right) or not (wrong).

the atmosphere of mercury and mars are very thin.what effects does the thin atmosphere on the temperature on the surface of this planet?
Answer:
The effects of the thin atmosphere are that the surface of the planet is going to be much hotter and not only that but also more radioactive than a planet with a thicker atmosphere. The thick atmosphere on other planets prevents a lot of radiation from going straight to the surface of the planet.

During hypnosis, people:
A. can accurately recall memories of early childhood and infancy.
B. lose all awareness of their surroundings.
C. temporarily suspend their sense of initiative.
D. are in a deep trance, which is similar to stage 3 NREM sleep.
During hypnosis, people temporarily suspend their sense of initiative. Hence, option (C) is correct.
What is hypnosis?
According to one definition, hypnosis is "a waking state of awareness, (or consciousness), in which a person's attention is diverted from his or her immediate surroundings and is consumed by interior experiences such as feelings, cognition, and images." In order to induce hypnosis, the subject must concentrate and become sufficiently absorbed in their imagination. A hypnotic world is created by the physician and patient through the use of suggestions and their acceptance.
Our everyday 'trance' states include things like becoming lost in a good book, driving down a familiar route without being aware of it, being in prayer or meditation, or engaging in a mindless or creative task. Our conscious awareness of our surrounds and an inner awareness exist on a continuum, thus even though one's emphasis is mostly internal in these states, one does not necessarily lose all awareness of the outside world.

Michael stands upright and allows his right arm to swing back and forth, naturally and without forcing, like a pendulum. He measures the time for 21 oscillations (complete cycles) to be 28.1 s. Assume his arm (length L) behaves as a simple pendulum, with an effective length of 2/3 L. Find the length of his arm, L.
Answer:
ytdgnrjjksmzjj3hfgbdhehkj jfjbcjbwbjrhrhb jdhbbjhhrhrhhjrjjr jfjnekrj
The length of his arm, L = 0.67 m.
What is time period?
A basic pendulum consists of a point mass hung by a tightly supported, weightless, and inextensible string.
T = 2π√ L/g, where L is the pendulum's length and g is the acceleration brought on by gravity, is the formula for a pendulum's period.
Given in the question the time for 21 oscillations (complete cycles) to be 28.1 s. Assume his arm (length L) behaves as a simple pendulum, with an effective length of 2/3 L.
T = 2π√ L/g
T = 2π√2l/3g
T = 28.1/21
T = 1.33
2π√2l/3g = 1.33
l = .67 m
The length of his arm, L = 0.67 m.

FIGURE 1 shows a 10 kg uniform metal rod with 2.0 m long pivoted at its centre C. A 20 N force is exerted on the rod, 0.5 m from point C. If the rod is in equilibrium, determine the
a) force, F needed.
b) magnitude and the direction of the force exerted at point C.
Answer:
Explanation:
Assuming we are looking parallel to a horizontal pivot pin with positive UP to the top of the picture, and the 20 N force acts perpendicular to the rod.
Sum moments about C to zero assume CW is the positive moment.
The rod mass causes no moment because there is no moment arm about C.
Fsin50[1.0} - 20[0.5] = 0
F = 10/sin50
F = 13 N
Summing vertical forces to zero With R being the pin reaction at C
Ry - F - 20sin50 - mg = 0
Ry = 13 + 20sin50 + 10(9.8)
Ry = 126.32 N
Summing horizontal forces to zero assuming a right directed force is positive.
Rx + 20cos50 = 0
Rx = -12.855...
R = √(-12.855² + 126.32²) = 126.972
R = 127 N
θ =arctan(126.32/-12.855) = 95.8107... = 5.8° CCW from UP

work is independent of the path taken between the points.
How does the current in a resistor change if the voltage across the resistor is
increased by a factor of 2?
If the voltage across a resistor is increased by a factor of two, the current in the resistor doubles.
What is ohm’s law?When all physical parameters and temperature are constant, Ohm's law claims that the voltage across a conductor is directly proportional to the current flowing through it.
This current-voltage connection may be expressed mathematically as,
The Equation of Ohm's Law;
V∝I
V'∝I'

How to find force if mass time and distance is given?
Answer:
For example, speed is a length divided by time. Force is mass times acceleration, and is therefore a mass times a distance divided by the square of a time. We therefore say that [Force] = MLT−2.
