Answer:68

Explanation:

6.8x100

We have that for the Question "A block weighing (Fg) 100 N is resting on a steel table (us = 0.68) ." it can be said that

The minimum force to start this block moving is [tex]F_{min}=37N[/tex]

From the question we are told

A block weighing (Fg) 100 N is resting on a steel table (us = 0.68)

The minimum force to start this block moving is. N.

Generally the equation for the Maximum force  is mathematically given as

[tex]F_{max} =0.74*50\\\\F_{max} =37N[/tex]

Therefore

The Minimum force = max Frictional force

Therefore

[tex]F_{min}=37N[/tex]

Hence

The minimum force to start this block moving is [tex]F_{min}=37N[/tex]

hi! newton's third law applies to a lot of things. this is shown when we jump, bounce a ball, or push something, for example. the law states that for every action, there an equal and opposite reaction. when you bounce a ball, it bounces back up at the same force at which you dropped it.

Answer:

250 m

Explanation:

In projectile, range is given as;

R = (v²sin 2θ)/g

We are given θ = 45°

Thus range of shell is;

R = (v²sin (2 × 45))/g

R = v²/g

Now, distance for the shell to hit the car will be; 150 + 14.14t

This will be equal to the range of shell;

150 + 14.14t = v²/g

Where t is time of flight

Now, time of flight is given by;

t = (2vsin θ)/g

t = (2v sin 45)/g

In surf form, we have;

t = (2v/(g√2))

Simplifying further gives;

t = (v√2)/g

Plugging this value of t into the distance equation gives;

150 + 14.14(v√2)/g = v²/g

Assuming g is 10 m/s², we have;

150 + 14.14(v√2)/10 = v²/10

Multiply through by 10 to get;

1500 + 14.14(v√2) = v²

v² - 20v - 1500 = 0

From quadratic equation calculator, we have; v = 50 m/s

Thus, t = (50√2)/g

t = (50√2)/10

t = 5√2

Plugging this into the distance equation gives;

Distance = 150 + 14.14(5√2) = 250 m

Answer:

Ek =  981000 [J]

Explanation:

To solve this problem we must use the principle of energy conservation, where kinetic energy is transformed into potential energy or vice versa. In this special case we take the reference level of potential energy in the soil (potential energy equivalent to zero). When the potential energy is zero, this energy has been transformed into kinetic energy and the velocity will be maximum.

[tex]E_{k} =\frac{1}{2}*m*v^{2}[/tex]

[tex]E_{p}=m*g*h[/tex]

where:

Ek = kinetic energy [J]

Ep = potential energy [J]

m = mass = 200 [kg]

h = elevation = 500 [m]

[tex]E_{p}= E_{k}[/tex] (energy conservation)

Ep = 200*9.81*500

Ep = 981000 [J]

And the kinetic energy is equal to:

Ek = Ep =  981000 [J]

Answer:

t = 9.36 s

Explanation:

Given that,

Initial velocity, u = 0 (at rest)

Final velocity, v = 77 m/s

Acceleration of the airplane, a = 8.2 m/s²

We need to find the time required for an airplane to take off its speed 77 m/s. Let t be the time. using first equation of motion to find it as follows :

v=u+at

[tex]t=\dfrac{v-u}{a}\\\\t=\dfrac{77}{8.22}\\\\t=9.36\ s[/tex]

so, the airplane will take 9.36 seconds.

an atoms ability to attract other electrons and form a chemical bond

since other one got deleted :(

Electronegativity is an atom's ability to attract other electrons and form a chemical bond.

The tendency of an atom of a given chemical element to attract shared electrons (or electron density) when forming a chemical bond is known as electronegativity.

The electronegativity of an atom is affected by its atomic number as well as the distance between its valence electrons and the charged nucleus. The higher the associated electronegativity, the more an atom or substituent group attracts electrons.

Electronegativity is a simple way to quantify bond energy as well as the sign and magnitude of a bond's chemical polarity, which characterizes a bond along a continuous scale from covalent to ionic bonding.

Hence, electronegativity is an atom's ability to attract other electrons and form a chemical bond.

Stars and planets form when dust and gas from space is pulled together by gravitation.

In mechanics, gravity, often known as gravitation, is the force of attraction that acts on all matter. It has little impact on determining the intrinsic characteristics of common stuff because it is by far the weakest known force in nature.

In contrast, it governs the formations and evolution of stars, galaxies, and the entire cosmos by its extensive and ubiquitous action, which affects the trajectories of objects in the solar system and beyond the universe. All objects on Earth experience weight, or a gravitational pull that is proportionate to their mass and is imposed by the planet's mass.

Hence, the stars and planets form when dust and gas from space is pulled together by gravitation.

Answer:

Explanation:

To the atomic mass;

1.   Atomic mass is the number of protons + neutrons;

  When a new proton is added, the atomic mass increases.

   When a proton is removed, the atomic mass reduces

The mass of an atom is concentrated in the nucleus where there is the proton and neutron.

2. Atomic number is the number of protons:

When a new proton is added, the atomic number increases

When a new proton is removed, the atomic number reduces

3. Charge:

 An atom is neutral if the number of positive charges is the same as negative charges:

    Protons = electrons

If :

   Protons > electrons = +Ve charges

   Protons < electrons =  -Ve charges

Answer: 6.0 m/s2

Explanation:

The acceleration of the block pushed horizontally with the force of 6 N is 3 m/s².

In order to move a body of mass 'm' kg with an acceleration of 'a' m/s², a force of magnitude → |F| = ma is needed to push the body in a specified direction.

Given is a 2 kg block being moved across a frictionless horizontal surface by a 6 Newton horizontal force.

Mass of block [m] = 2 Kg

Force on block [F] = 6 N

From the definition of force -

|F| = ma

6 = 2 x a

6 = 2a

a = 3 m/s²

Therefore, the acceleration of the block pushed horizontally with the force of 6 N is 3 m/s².

Explanation:

Answer:

47.4 ft/s

Explanation:

Using v² = u² - 2gs where u = initial vertical velocity of ball = 100sin30, v = final vertical velocity of ball at the time it was caught by the fielder, g = acceleration due to gravity = 32 ft/s² and s = vertical displacement = y₂ - y₁, y₁ = 3 ft and y₂ = 7 ft. s = y₂ - y₁ = 7 - 3 = 4 ft

Substituting these values into the equation, we have

v² = u² - 2gs

v² = (100sin30)² - 2 × 32ft/s² × 4 ft

v² = (100sin30 ft/s)² - 256 ft²/s²

v² = (50 ft/s)² - 256 ft²/s²

v² = 2500 ft²/s² - 256 ft²/s²

v² = 2244 ft²/s²

v = √2244 ft²/s²

v = 47.37 ft/s

v ≅ 47.4 ft/s

So, the velocity of the ball relative to the fielder at the instant the catch is made is 47.4 ft/s.

Thus, Ew=Fd=E (P=E/t)
