Suppose an asteroid orbits the sun with a mean radius 11 times that of Earth. Use the simplified version of
Kepler's third law (T2= a³) to find the period of the asteroid? Round your answer to the nearest Earth year.

The time shown by the speedometer corresponding to speed of 10 m/s is 1 s.

The time shown by the speedometer corresponding to speed of 20 m/s is 1 s.

The time shown by the speedometer corresponding to speed of 30 m/s is 1 s.

1. As shown by the speedometer on the right.

The speed of 10 m/s indicated by the speedometer to the right may be used to calculate how long the ball has been falling from the maximum altitude it reached.

Equation for free fall: Vf = Vo - gt

Vo=0, Vf=gt, and t=Vf/g

I suggest using an approximation of g for this problem: g = 10 m/s2 (I'll explain why in a moment).

1 second is equal to [10 m/s]/[10 m/s2].

The time is now dropping. From it has been four seconds since launch, the upward time was three seconds. You may use this to determine the launching speed.

2. The moment the speedometer registers 20 m/s

Determine the launching speed first:

Vo - gt = Vf

Given that the ball took 3 seconds to ascend and that its speed was zero at its highest point, you may calculate:

0 = Vo - gt

Vo=gt=10 m/s2 3 s = 30 m/s

Now, while the ball is moving upward and the speedometer reads 20 m/s, use the beginning velocity to compute.

t = [30 m/s - 20 m/s] / [10 m/s2] = 1 s 20 m/s = 30 m/s - 10 m/s2

Therefore, t = 1 s is the initial solution.

3. The moment the speedometer registers 30 m/s.

The projected speed for the launch is also 30 m/s.

This reading therefore reflects the precise moment the ball was released.

Time is therefore 0 and the launch moment remains the same.

The mean value of the measurements is 2.2 cm³.

The attributes of an object or an event are measured and quantified so that they can be compared to other things or events.

Therefore, measurement is the process of determining the size or smallness of a physical quantity in comparison to a primary reference quantity of a similar kind. The range and applications of measurement depend on the situation and industry.

Measurements do not apply to nominal attributes of things or occurrences in the natural sciences and engineering, as stated in the International Vocabulary of Metrology published by the International Bureau of Weights and Measures. Measurement is essential to trade, science, technology, and quantitative research in many fields.

Mean of the measurements = (2.1+2.1+2.4)/3 = 6.6/3 = 2.2 cm³.

Newton's second law states that the product of the box's mass and acceleration determines the net force acting on the object. T, which equals f= 23.52 N, must be applied in order to move up the ramp.

The behaviour of objects for which all external forces are balanced is predicted by Newton's first law of motion. According to the first law, sometimes known as the law of inertia, an object's acceleration will be zero metres per second per second if the forces acting on it are evenly distributed. When everything is in balance, or equilibrium, objects cannot accelerate. According to Newton, an item will only accelerate if another force is operating on it that is net or imbalanced. If an imbalanced force is present, the object will accelerate and change its direction and speed, or both. The behaviour of objects for whom all external forces are not balanced is covered by Newton's second law of motion.

An object that is speeding occasionally has a constant change in velocity over time. As was said in the previous sentence, the data table above depicts an object increasing its velocity by 10 m/s every second. Since there is a constant change in velocity every second, this is known as a constant acceleration. Contrary to popular belief, an object with constant acceleration is distinct from one with constant velocity. Refuse to be duped! Furthermore, a moving item at a constant speed is not accelerating. The following data tables show the motions of objects moving at a constant acceleration and at a variable acceleration. The three main categories of accelerated motions are uniform, non-uniform, and average acceleration.

Answer:

Choice d: support force (normal force) on the cat and the weight of the cat are equal in magnitude.

Explanation:

The cat in this question is stationary. As a result, the acceleration of this cat will be zero. By Newton's Second Law of Motion, the net force on this cat will also be zero.

If the floor is level, there will be two forces acting on this cat:

For the net force to be zero, these two forces need to balance each other. For that, they need to have the same magnitude and point in opposite directions. Therefore, the magnitude of the support force (normal force) will be equal to the magnitude of the weight of this cat.

If a 0.12-kg apple falls off a tree branch that is 2.3 m above the thick grass. The apple sinks 0.067 m into the grass while stopping, then the average contact force that grass would exert on the apple would be 1.177 Newtons.

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.

As given in the problem if a 0.12-kg apple falls off a tree branch that is 2.3 m above the thick grass. The apple sinks 0.067 m into the grass while stopping,

The contact force on the apple = 0.12 × 9.81

carries the "same current" - the first option

If two balls the same size and different masses go down a ramp, they will move at the same speed.

The phrase "rolling down a frictionless slope" is illogical. The translational and rotational motions of the balls are completely uncoupled if the slope has no friction, and the balls just slide down the slope.

I believe the situation when there is static friction, allowing the balls to roll without slipping, is what you are most interested in.

In either case, the velocity as a function of distance along the ramp (v(s)) for uniform spheres ends up being independent of both the mass and the radius. Additionally, the duration of the descent is simply the integral of ds/v(s), which is also independent of the mass and radius.

As a result, they move at the same speed regardless of position and arrive at the bottom at the same moment.

A tiger leaps horizontally from a 5.5 m rock with a speed of 3.6 m/s. So the tiger will land 2.772 m away from the base.

In mechanics, acceleration refers to how quickly an object's velocity alters in relation to time. The vectorized magnitude of accelerations. An object's acceleration is determined by the direction of the net force pushing against it.

Acceleration has a direction and a magnitude, making it a vector quantity. A vector quantity is a velocity as well. Acceleration is defined as the change in the vector of velocity over a period of time divided by the duration of the change.

According to the question, the given values are,

For y component :

Acceleration, a = -9.8 m/s²

Velocity, v₀= 0 m/s

Δy = -5.5 m

For x component :

a = 0 m/s²

v₀ = 3.6 m/s

Δy = v₀t + 1/2 at²

- 5.5 m = 0 + 1/2(-9.8)t²

t = 0.77 seconds

Δx = v₀t + 1/2 at²

Δx = (3.6)(0.77) + 0

Δx = 2.772 meters.
