Hello, I needed help with a few assignment questions. Thank you. It's about Newton's second law of motion.
We will have the following:
2) We can determine that the ratio is constant due to the fact that the acceleration of the gravity on Earth remains constant on the planet. And the mass of the planet is constant.
3) What causes the objects accelerate is the mass of the body that supports them and the mass of the very object. In clasical mechanics the acceleration is due to the influence that a body imparts on another. In relativistic mechanics the acceleration is due to the warping of the space that makes the bodies towards the one with a bigger sphere of influence.
It can also be interpreted as the relationship of the force that is imparted on a body by another and the mass of the smaller object.
A jet of water squirts out horizontally froma hole on the side of the tank as shown below. If the hole has a diameter of 3.62 mm, whatis the height of the water above the hole inthe tank?Answer in units of cm.
The jet of water emerges with a speed v horizontally. Then, it falls a vertical distance of 1.58, and during the time of its fall until it hits the ground, it travels a distance of 0.586 meters.
Since the water moves according to the Projectile Motion formulas, the horizontal motion is uniform and the vertical motion is uniformly accelerated from rest.
Then, we can use the vertical distance to find the time that it takes for the water to reach the ground. Then, divide the horizontal distance traveled by the water by the time it took for the water to fall to find the horizontal speed of the water.
Finally, use Torricelli's Theorem to relate the height of the water above the hole in the pipe to the horizontal speed. Find the height of the hole by isolating it and replacing the value of the known variables.
Step 1: Time
Since the water falls from rest a distance of 1.58m, and the time it takes for an object to fall a distance d in free fall from rest is given by:
[tex]t=\sqrt[]{\frac{2d}{g}}[/tex]Then, replace d=1.58m and the value of the acceleration of gravity g=9.81m/s^2 to find the time it takes for the water to fall:
[tex]t=\sqrt[]{\frac{2(1.58m)}{9.81\frac{m}{s^2}}}=0.5675564161\ldots s[/tex]Step 2: Speed
Since the water travels a horizontal distance of 0.586m during that time, then, the speed of the water jet as it emerges from the hole, is:
[tex]v=\frac{x}{t}=\frac{0.586m}{0.5675564161\ldots s}=1.032496477\ldots\frac{m}{s}[/tex]Step 3: Height (Torricelli's Theorem)
According to Torricelli's Theorem, the speed of a liquid jet emerging from a hole located a distance h below the level of water of a large container, is:
[tex]v=\sqrt[]{2gh}[/tex]Isolate h from the equation:
[tex]h=\frac{v^2}{2g}[/tex]Replace v=1.032496477...m/s and g=9.81m/s^2 to find the height of the water above the hole in the tank:
[tex]h=\frac{(1.032406477\ldots\frac{m}{s})^2}{2(9.81\frac{m}{s^2})}=0.05433481013\ldots m\approx5.43\times10^{-2\text{ }}m[/tex]Write the answer in cm:
[tex]h=5.43cm[/tex]Therefore, the height of the water above the hole in the tank is 5.43 centimeters.

Two unequal masses m and 2m are attached to a thin bar of negligible mass that rotates about an axis perpendicular to the bar. When m is a distance 2d from the axis and 2m is a distance d from the axis, the moment of inertia of this combination is i.
The moment of inertia for this combination is I when m is 2d from the axis and 2m is 2d from the axis, therefore I = mr2.
Explain the moment of inertia.Moment of inertia is a word used to describe a physical property that measures how resistant a body is to having the speed of its rotation along an axis modified by the application of a torque (turning force).

By what factor does the gravitational force between two objects increase if one object doubles in mass and the distance between them decreases by half?
The factor is that since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.
What is gravitational force?Gravitational force is described as the universal force of attraction, which is acting between objects. This force causes mutual attraction between all things with mass or energy.
The newton's law of universal gravitation states that every particle in the universe attracts every other particle with a force along a line joining them. The force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Imagine a person moving quickly, taking one stride ahead, one step back, and then beginning from the same place each time. A vector quantity is velocity. As a result, velocity is aware of direction. One must consider direction while calculating an object's velocity. Saying that an item has a velocity of 55 miles per hour is insufficient.
