[tex]\huge\underline\mathtt\colorbox{cyan}{For Positively Charged:}[/tex]

By gaining electrons from the ground, the object will have a balance of charge and therefore be neutral. Grounding is the grounding of a positively charged object and involves the transfer of electrons from the ground into the object.

[tex]\huge\underline\mathtt\colorbox{red}{For Negatively Charged:}[/tex]

If it is to have its charge removed, then it will have to lose its excess electrons. Once the excess electrons are removed from the object, there will be equal numbers of protons and electrons within the object and it will have a balance of charge.

Answer:

The main intermolecular forces present in water is hydrogen bond.

It is followed by,

Dipole-dipole attractions

Dipole-induced dipole attractions

London dispersion forces

The hydrogen bonds are the strongest force, but the other types of intermolecular attraction are still present.

Answer:

In a second class lever, the load is located between the effort and the fulcrum. If the load is closer to the fulcrum than the effort, then less effort will be required to move the load. If the load is closer to the effort than the fulcrum, then more effort will be required to move the load.

Explanation:

from what i learned, if its farther away from the load, its easier to lift, like a wheel barrel

The conservation of the momentum allows to find the result of how the astronaut can return to the spacecraft is:

The momentum is defined as the product of the mass and the velocity of the body, for isolated systems the momentum  is conserved. If we define the system as consisting of the astronaut and the evo propellant, this system is isolated and the internal forces become zero. Let's find the moment in two moments.

Initial instant. Astronaut and thrust together.

        p₀ = 0

Final moment. The astronaut now the thruster in the opposite direction of the ship.

       [tex]m_f[/tex] = m v + M v '

where m is propellant mass and M the astronaut mass.

As the moment is preserved.

       0 = m v + M v ’

      v ’= [tex]- \frac{m}{M} \ v[/tex]  

We can see that the astronaut's speed is in the opposite direction to the propeller, that is, in the direction of the ship.

The magnitude of the velocity is given by the relationship between the masses.

In conclusion, using the conservation of the momentun we can find the result of how the astronaut can return to the ship is:

i would say B decrease mass of cannon or decrease mass of cannon ball

Explanation:

because when you fire the cannon the cannon ball and powder exit the cannon then that leaves the cannon ball and i would say that the explosion would force it out the cannon but would not increase its mass.

Explanation:

Free fall means that an object is falling freely with no forces acting upon it except gravity, a defined constant, g = -9.8 m/s2. The distance the object falls, or height, h, is 1/2 gravity x the square of the time falling.

Answer:

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

[tex]a = \frac{f}{m} \\ [/tex]

f is the force

m is the mass

From the question we have

[tex]a = \frac{2000}{100} = 20 \\ [/tex]

Answer:

Another ship travels at an average velocity of 26 km/h for

Explanation:

Ship one will cover a distance of 77 km after 2.2 hours and ship two will cover a distance of 65 km after 2.5 hours.

The average speed of an object is the average distance it covers in a given length of time. The scalar number reflects the average speed. Direction can be replaced with magnitude.

[tex]Average\ speed=Total\ distance/Total\ time[/tex]

Average velocity is a vector quantity. The change in position or displacement divided by the periods of time during which the change occurs is known as average velocity. Depending on how the displacement has been adjusted, the average velocity could be either positive or negative. Meters per second (m/s), or average velocity, is the SI measure for speed.

[tex]Average\ Velocity=Total\ displacement/Total\ time[/tex]

According to the question,

Ship one has an average velocity of 35 km/h for 2.2 hours.

So, total distance covered by ship one = 35 × 2.2 = 77 km.

Ship one has an average velocity of 26 km/h for 2.5 hours.

So, total distance covered by ship one = 26 × 2.5 = 65 km

Hence, the distance covered by ship one is 77 km and ship two will cover 65 km.

Answer:

around 1436.76 cm^3

Explanation:

v = 4/3(3.14)7^3

v = 4/3(3.14)343

v = 4/3(1077.02)

v = 1436.02666667

round up

v = 1436.027

if you use pi, then the answer would be around 1436.76 cm^3

The initial horizontal velocity of the projectile is 22.1 m/s.

The given parameters;

The time of motion of the object is calculated as follows;

h = ut + ¹/₂gt²

where;

h = ¹/₂gt²

[tex]t = \sqrt{\frac{2h}{g} } \\\\t = \sqrt{\frac{2\times 25}{9.8} } \\\\t = 2.26 \ s[/tex]

The initial horizontal velocity of the projectile is calculated as follows;

R = vₓt

[tex]v_x = \frac{R}{t} \\\\v_x = \frac{50}{2.26} \\\\v_x = 22.1 \ m/s[/tex]

Thus, the initial horizontal velocity of the projectile is 22.1 m/s.

Answer:

Solubility in gasses and liquids increase as pressure increases. This is due to colligative properties. The nitrogen gas levels would increase the farther the diver dives due to the increase of pressure causing the solubility of the nitrogen to increase, thus increasing the amount of it as you go deeper in the ocean.

Explanation:

As they plummet down, the driver would be in more risk. The solubility of gases and liquids increases as pressure increases. This is due to the existence of colligative properties. The nitrogen gas levels grow when the diver descends further into the water due to increased pressure, which causes the nitrogen's solubility to rise, increasing the amount of nitrogen present.

The equation of the constructor of the geomeric optics allows to find the results for the distance and size of the objects are:

The equation of the constructor of geometric optics describes the position of objects and their images for mirrors and lenses.

       [tex]\frac{1}{f} = \frac{1}{p} + \frac{1}{q}[/tex]  

Where f is the focal length, p and q are the distances to the object and the image, respectively.

They indicate the focal length f = 10 cm, the distance to the image q = 40 cm, that the height s h ’=  4 cm.  In the attachment we see a scheme of the system.

Let's find the distance to the object.

        [tex]\frac{1}{p\frac{x}{y} } = \frac{1}{f} - \frac{1}{q} \\\frac{1}{p} = \frac{1}{10} - \frac{1}{40}\\\frac{1}{p} = 0.075[/tex]

       p = 13.3 cm

The magnification in the ratio of image size to object size.  The image is inverted so its height is negative.

        [tex]m = \frac{h'}{h} = - \frac{q}{p}\\h = - \frac{p}{q} \ h'\\h = - \frac{13.3}{40}\ (-4)[/tex]

        h = 1.33 cm

In conclusion using the equation of the constructor we can find the results for the distance and size of the objects are:
