Answer:

660

Explanation:

0.011kW = 11W

energy = 11 x 60

            = 660J

Answer:

a)  [tex]v_{oy}[/tex] = 0,  b)  t = 9.035 s, c) x = 587.275 m, d)  v_y = -88.54 m / s,

e) v = 109.84 m / s,  f)  θ = -53.7º

Explanation:

This exercise is a projectile launch

a) as the projectile is launched horizontally, its initial vertical velocity is zero

          [tex]v_{oy}[/tex] = 0

b) let's use the relation

          y = y₀ + v_{oy} t - ½ g t²

when reaching the ground y = 0 and the initial vertical velocity is v_{oy}=0

         0 = y₀ + 0 - ½ g t²

         t = [tex]\sqrt{ \frac{2 v_o}{g} }[/tex]

         t = [tex]\sqrt{ \frac{ 2 \ 400 }{ 9.8} }[/tex]

         t = 9.035 s

c) the horizontal distance is

         x = v₀ₓ t

         x = 65  9.035

         x = 587.275 m

d) the vertical speed when touching the ground

         v_y = [tex]v_{oy}[/tex] -gt

         v_y = 0 - 9.8 9.035

          v_y = -88.54 m / s

the negative sign indicates that the velocity is directed downwards

e) the velocity at this point

          v = [tex]\sqrt{ v_x^2 + v_y^2}[/tex]

          v = [tex]\sqrt{65^2 + 88.54^2}[/tex]

          v = 109.84 m / s

f) the direction of the velocity

let's use trigonometry

          tan θ = v_y / vₓ

          θ = tan⁻¹1 v_y / vₓ

          θ = tan⁻¹ (-88.54 / 65)

          θ = -53.7º

this angle is measured clockwise

Este tipo de indagación ayuda al individuo a aprender cosas nuevas.

Fluorine is the sample which is shiny but does not conduct heat and electricity through it. The flow of electricity requires the flow of electrons or charged particles. Thus, the correct option is A.

A conductor is a substance, chemical element, or a material which allows electricity and heat to flow through it. In a conductor, the electrical charge carriers which are usually electrons or positive and negative ions, move easily from one atom to another atom when a particular amount of voltage is applied.

Fluorine is a shiny element however it does not conduct heat and electricity through it. It is the most electronegative atom and is very reactive in nature. It only gains electrons and does not lose them. And because of this property of fluorine, it restricts the movement of electrons through it and fails to conduct electricity.

Therefore, the correct option is A.

Answer:

floating had to do with the pressure rather than the weight

Explanation:

the water pressure on the bottom of the boat is so hard and pushing that it causes it to float.. And the steel ball has alot of density. which is causing it to sink

Answer:

because of its displacement, a ship displaces water. when a steel ball does not.

Answer:

A ball when from moving to stoping

Explanation:

Kinetic = energy of motion

Potential = energy stored

When you roll a ball on the ground, it gains kinetic energy, but then the ball starts to slow down until it stops and it remains at rest which means it's at potential energy. It went from moving (kinetic) to stoping (potential)

Answer:

Your answer should be B. a parabola.

Explanation:

The path of the projectile in the absence of friction is a parabola. Therefore, option (b) is correct.

Projectile motion can be described as a form of motion experienced by a projectile that is projected near the surface of the earth and moves along a curved path under the action of gravity. This curved path is to be a parabola, but may also be a straight line in special cases when the projectile is thrown directly upwards.

The study of such motions is known as ballistics and the only force that is actively exerted is gravity, which acts downward, thus giving the object a downward acceleration toward the Earth’s center of mass.

No external force is required to maintain the horizontal velocity component of the object's motion because of the object's inertia. Other forces, such as aerodynamic drag or internal propulsion need additional analysis.

Therefore, the path of an object or projectile is generally parabola in the absence of friction.

Answer:

Explanation:

The current produced by a 9-volt battery flowing through a resistance of 0.2 ohms would be  45 Ampere.

Resistance is the obstruction of electrons in an electrically conducting material.

The mathematical relation for resistance can be understood with the help of the empirical relation provided by Ohm's law.

V=IR

As given in the problem we have to find the current produced by a 9-volt battery flowing through a resistance of 0.2 ohms.

current produced by a 9-volt battery  = voltage /resistance

                                                              = 9 volt /0.2 ohms

                                                              = 45 Ampere

Thus, the current produced would be 45 Ampere.

Answer:

so the answer is number one which is A

Answer:

Ver respuesta en el procedimiento

Explanation:

En este caso, necesitamos la expresión que nos permite hallar el Trabajo realizado por un objeto a través de una distancia dada. Esa expresión es:

W = F * x   (1)

Donde:

W: Trabajo en Joules (J)

F: Fuerza en Newton (N)

x: Distancia o radio en metros (m)

En este caso, solo tenemos una masa de 800 lb, y la distancia que se esta recorriendo. No tenemos ningún dato adicional que nos diga si por ejemplo, es empujado por una persona o parecido, solo los datos de la masa que lleva la carreta. Por lo tanto, la única fuerza que podemos asumir se está ejerciendo, sería la fuerza del peso del objeto que se calcula así:

P = mg   (2)

Donde:

g: aceleración de gravedad (9,8 m/s²)

Ahora bien si reemplazamos (2) en (1) nos queda:

W = mgx  (3)

Y antes de realizar el cálculo debemos convertir la unidad de masa en libra a kilogramo, usando la siguiente conversión:  1 lb -----> 0,454 kg por tanto:

m = 800 * 0,454 = 363.2 kg

Ahora podemos usar (3) y calcular el trabajo:

W = 363,2 * 9,8 * 100

W = 355936 J o simplemente 355,936 kJ

Espero te sirva.

PD: También puedes usar el valor de gravedad como 10 m/s² y tendrás un resultado de 363200 J o 363,2 kJ.

Answer:

the work done is zero.

Explanation:

Given;

applied force, F = 8000 N

time of force application, t = 15 s

Work done is given as the product of force and displacement. Since the car is unable to move, then the displacement is zero and the work done is zero.

Work done = Force x displacement

Work done = 8000 N x 0

Work done = 0

Therefore, the work done is zero.

Answer:

Earth’s gravitational force is stronger

Explanation:

Earth’s gravitational force is stronger than the moon because of the presence of more massive objects in earth; on the flip side, the moon’s gravity is weaker than the earth due to smaller in size as compared to the earth. Earth gravity is denoted by g; conversely, moon gravity is denoted by gm

Answer: The greater an object's mass, the more gravitational force it exerts. So, to begin answering your question, Earth has a greater gravitational pull than the moon simply because the Earth is more massive. That's why the moon isn't pulled out of Earth's orbit by the gravity of larger planets or by the sun.
