What does it say about the application of Newtons second law of motion in football

Answers

Answer 1

Answer:

Newton's Second Law of Motion states that a force on an object is equal to the mass of the object multiplied by its acceleration ( F = ma ).

The football then exerts an equal amount of force in the opposite direction on the kicker's foot.

Everything in football that has a mass and acceleration will have a force.

Explanation:

Answer 2

Answer:

The more force applied to the football the more acceleration. Kicking or throwing the ball harder makes it move faster and cover more distance.

difference between centripetal and centrifugal force

Answers

Answer:

A centripetal force (latin: towards the center) is a force shown in any motion that does NOT go in a straight line, related to the fact that your velocity vector changes in direction, and thus you have an acceleration that goes in the same direction - adding an image for more clarity.  Rest is just having to remember that acceleration and the force that causes it have the same direction, as do acceleration and change in velocity.

Centrifugal force (latin again: away from the center) is an apparent force, related to the fact that bodies have a tendency - called inertia - of wanting to keep their state of straight motion (or stillness, in case they're not moving to begin with). The moment they get accelerated in a curved trajectory (think a ball on the back seat of a car rolling to the outer side of the curve, you yourself being pushed towards the door if someone drives quite aggressively, or if you are into flight, the ball in a steam gauge turn coordinator, the internet should have photos of it), they receive an apparent acceleration relative to the frame of the moving place where they are, while they try to keep thier relative motion compared to an inertial frame of reference (ie, the rest of the earth).

If U=53m/s and find the launch angle such that the maximum height of the projectile is equal to three times the horizontal range​

Answers

Answer:

t = V0 sin theta / g      time to get max height

h = Voy t - 1/2 g t^2 = Vo^2 sin^2 theta / 2 g          max height

R = V0^2 sin 2 theta / g      range formula

h = 3 R        given

Vo^2 sin^2 theta / 2 g = 3 * V0^2 sin 2 theta / g

sin^2 theta = 6 * sin 2 theta = 12 * sin theta cos theta

tan theta = 12

theta = 85.2 deg

Can check:  

Vx = 8.37

Vy = 99.6     assuming V0 =100

t = 99.6 / 9.8 = 10.2 sec     to reach max height

Sx (total range) = 2 * 10.2 * 8.37 = 170 m

Sy = 1/2 * 9.8 * (10.2)^2 = 510 m

Height = 3 * range

Un bloque de cobre cuya masa es 250 gramos , absorbe calor y su temperatura se eleva de 20 ˚C a 150 `C. ¿Cuál es la cantidad de calor absorbida por el bloque de cobre?. Expresar el resultado en unidades caloríficas y en unidades mecánicas.

Answers

Dada la información de la pregunta, el calor absorbido por el cobre es de 12513 J o 2990 calorías.

El calor ganado se obtiene de la relación;

H = mcdt

Dónde;

H = calor absorbido

m = masa

c = capacidad calorífica del cobre

Δt = cambio de temperatura

La capacidad calorífica del cobre es de 385 J / kg / ° C

Entonces;

m = 250 gramos o 0,25 kg

Δt = 150 ° C - 20 ˚C = 130 ˚C

H = 0,25 kg * 385 J / kg / ° C * 130 ˚C

H = 12513 J o 2990 calorías

Explain Beryllium chloride molecule ( Formation of BF3 molecule and NH3 molecule )​

Answers

Answer:

Here it is!

Explanation:

BeCl2 referred to as Beryllium Chloride, is an inorganic compound. It appears as white or yellow crystal solid at room temperature. It can exist in both monomeric and 1-D polymeric forms. The properties of beryllium chloride are similar to aluminum chloride owing to the diagonal relationship of beryllium with aluminum.

The molar mass and melting point of beryllium chloride are 79.91 g/mol and 399 °C, respectively. The chemical bonding in Beryllium Chloride is studied by writing down its Lewis structure by following the Lewis approach.

After lewis structure, there is a need of understanding its molecular geometry and hybridization of the central atom, Beryllium. The molecular orbital (MO) theory will be used to understand the MO diagram of beryllium chloride.

As a result, an ionic compound Beryllium chloride is formed.

Boron Fluoride (BF3)

Boron trifluoride is formed through interaction of π bonds with the double alpha bonds of fluorine.

When a capacitor is charged, the electric field E, and hence the electric flux Φ, between the plates changes. This change in flux induces a magnetic field, according to Ampère's law as extended by Maxwell: ∮B⃗ ⋅dl⃗ =μ0(I+ϵ0dΦdt). You will calculate this magnetic field in the space between capacitor plates, where the electric flux changes but the conduction current I is zero. A parallel-plate capacitor of capacitance C with circular plates is charged by a constant current I. The radius a of the plates is much larger than the distance d between them, so fringing effects are negligible. Calculate B(r), the magnitude of the magnetic field inside the capacitor as a function of distance from the axis joining the center points of the circular plates. Express your answer in terms of μ0 and given quantities. B(r) =

Answers

The magnitude of the magnetic field B(r) inside the capacitor as a function of distance from the axis is [tex]\mathbf{B(r) =\dfrac{\mu_o I r}{2 \pi a^2} }[/tex]

A charged capacitor usually cause changes between the plates of electric field E and the electric flux Φ

As seen in Ampere's law which is extended by Maxwell:

[tex]\mathbf{\oint B^{\to} .dl^{\to} = \mu_o \Big( I+\dfrac{d \phi }{dt} \Big)}[/tex]

To meet the equilibrium equation of electric charge, Maxwell modified Ampere's law by incorporating the displacement current through into electric current component.

The displacement current can be expressed by the relation;

[tex]\mathbf{I = \varepsilon_o \dfrac{dE}{dt} }[/tex]

From the given information, the displacement current density through area A can now be expressed as:

[tex]\mathbf{I = \varepsilon_o A \dfrac{dE}{dt} }[/tex]

Replacing the value of displacement current density into Maxwell modified Ampere Law, we have:

[tex]\mathbf{\oint B .dl= \mu_o I_{enclosed} }[/tex]

[tex]\mathbf{B \times (2 \pi r) = \mu_o I\Big (\dfrac{\pi r^2}{\pi a^2} \Big) }[/tex]

a bolwing ball has a mass of 6 kilograms a tennis ball has a mass of 0.06 kilograms

Answers

To compare the magnitude of the inertia of the bowling and tennis ball, we take the ratio of their masses. Hence, the bowling ball has 100 times the inertia of the tennis ball.

Given the Parameters :

Mass of bowling ball = 6 kilogram Mass of tennis ball = 0 06 kilogram

Taking the ratio of the masses :

Mass of bowling ball / Mass of tennis ball

Inertia = 6kg / 0.06kg

Inertia = 100

Hence, the inertia of the bowling ball is 100 times that of the tennis ball.
