A “real” image occurs when light rays actually intersect at the image, and become inverted, or turned upside down. ... In flat, or plane mirrors, the image is a virtual image, and is the same distance behind the mirror as the object is in front of the mirror. The image is also the same size as the object.

Answer: Ted and Tim

Explanation:

The football players Ted and Tim have the same momentum, which is 120 kg m/s. Hence, option C is correct.

The momentum is the result of a particle's velocity and mass. Force and motion, meaning it has both magnitude and direction. According to Isaac Newton's second equation of motion, the force acting on a particle equals the time rate of increase of momentum.

The impulse, which is the product of the force and the intervals (the impulse), is equal to the difference in momentum, according to Newton's 2nd law, if a steady force operates on a particle for a specific amount of time. On the other hand, a particle's momentum is the amount of time needed for a consistent action to fight it to rest.

As per the given information in the question,

The momentum of Ted is,

p = 60 × 2 = 120 kg m/s

The momentum for Todd is,

p = 80 × 1.7 = 136 kg m/s.

The momentum of Tom is,

p = 90 × 1.5 = 135 kg m/s and,

The momentum for Tim is,

p = 100 × 1.2

p = 120 kg m/s.  

After comparing the momentum of all the players, Ted and Tim have similar momentum.

Answer:

P = 100 lb

Explanation:

For an ideal machine:

[tex]Work\ In = Work\ Out\\(P)(L)=(W)(H)[/tex]

where,

P = Effort = Input Force = ?

L = Effort Arm = Length of inclined plane = 10 ft

W = Load to be lifted = 200 lb

H = Load Arm = Height = 5 ft

Therefore,

[tex]P(10\ ft) = (200\ lb)(5\ ft)\\\\P = \frac{(200\ lb)(5\ ft)}{10\ ft}[/tex]

Answer:

A) 49,050 N

B) 16 m

Explanation:

Question:

El dibujo de la pregunta se obtiene de un documento titulado "TRABAJO DIVERSO Y ENERGÍA" que se encuentra en línea y se presenta aquí.

La masa dada del vagón, m = 1,000 kg

La altura del punto en el que descansa el vagón, punto 1, h₁ = 12 m

A) El radio en el punto 2, el punto más bajo, R = 6 m

La fuerza, 'N', que la vía ejerce sobre el vagón en el punto 1 viene dada por la siguiente relación;

N = El peso del vagón + La fuerza de movimiento del vagón

∴ N = m × g + m × a

Dónde;

g = La aceleración debida a la gravedad ≈ 9,81 m / s²

a = La aceleración del vagón

Observamos que para el movimiento circular, la fuerza de movimiento del vagón, m × a = La fuerza centrípeta que actúa sobre el vagón = m × v² / R

∴ m × a = m × v² / R

Dónde;

v² = La velocidad del vagón en el punto 2 = 2 · g · h₁

Por lo tanto;

N = m × g + m × a = m × g + m × v² / R = m × g + m × 2 · g · h₁ / R

∴ N = 1000 × 9,81 + 1000 × 2 × 9,81 × 12/6 = 49,050

La fuerza que ejerce el vagón en el punto 2, N = 49,050 N

B) En el punto 3, tenemos;

N = m · g - m · a₃

La fuerza centrípeta en el punto 3, m · a₃ = m · v₃² / R₃

∴ La altura en el punto 3, h₃ = 4 m

El cuadrado de la velocidad en el punto 3, v₃² = 2 · g · (h₁ - h₃)

Para que el vagón esté seguro en el punto 3, la fuerza de la vía sobre el vagón, N = 0 para que el vagón permanezca en la vía actuando

Por lo tanto;

N = m · g - m · a₃ = 0

m · g = m · a₃ = m · v₃² / R₃ = m · (2 ​​· g · (h₁ - h₃)) / R₃

∴ R₃ = (2 · g · (h₁ - h₃)) / g = (2 · (h₁ - h₃)) = 2 × (12 - 4) = 16

El radio de curvatura en el punto 3 para que el punto sea seguro es R₃ = 16 m.

Answer:

Resistance, R = 2.5 Ohms

Explanation:

Given the following data;

Voltage = 10 V

Current = 4 A

To find the resistance;

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

[tex] V = IR[/tex]

Where;

V represents voltage measured in voltage.

I represents current measured in amperes.

R represents resistance measured in ohms.

Making resistance, R the subject of formula, we have;

[tex] R = \frac {V}{I} [/tex]

Substituting into the equation, we have;

[tex] R = \frac {10}{4} [/tex]

Resistance, R = 2.5 Ohms

Therefore, the resistance of the resistor in the electrical circuit is 2.5 Ohms.

Answer:

M= -10/4

M = -5/2

-5/4 + m = -15/4

Explanation:

3/4 + m = -7/4

Subtract 3/4 from both sides

3/4 + m - 3/4 = -7/4 - 3/4

m = (-7-3) / 4

m = -10/4

m = -5/2

Check the options

11/4 + m = -1/4

m = -1/4 - 11/4

m = (-1-11) /4

m = -12/4

m = -3

-5/4 + m = -15/4

m = -15/4 + 5/4

m = (-15+5) /4

m = -10/4

m = -5/2

The distance that the honey flowed would be the dependent or outcome variable and the temperature of the honey would be the independent variable.

The dependent variable is what is being measured in an experiment. You can remember it by thinking “it depends on what you’re changing.”

The independent variable in an experiment is what is being changed. You can remember this by thinking “the Independent variable is what I as the scientist change.”

Explanation:

mark me brainliest plz

In the experiment " Temperature" is dependent variable and the distance honey flows is independent variable.

It is the factor that one can purposely control or change to observe its effect , is called independent variable.

It respond to the change in the independent variable , is called dependent variable.

Explanation:

To understand photoelectric effect the physicists has to view light as a particle and not wave. The wave nature of the light could not explain the phenomenon of photoelectric effect.

Photoelectric effect is emission of electrons from a material when electromagnetic radiation(Light) is incident on it. These emitted electrons are called photoelectrons.

The explain this effect Einstein proposed that beam of light is can not be a wave propagating through space, but a swarm of discrete energy packets, called as photons.

Answer:

Oxygen starts with six valance electrons and ends with six valance electrons but after bonding has parts of the densities of 8 electrons

Explanation:

Chemical bonding does not increase the valance electrons. Oxygen has 6 valence electrons. Bonding is sharing of valance electrons

The electron density of two of the valance electrons of Oxygen are shared with the Hydrogen atoms. The Hydrogen atoms is turn share part of the electron density of their single electron with Oxygen.

This means that there are parts of 8 electron densities around the Oxygen. This does not increase the number of valance electrons of Oxygen. (Note the sharing is very unfair, Oxygen gets more than its

share of the electron densities of the two electrons used for the chemical bond.

Explanation:

Answer:

the weight of the astronaut on Earth is 1209.88 N

Explanation:

Given;

weight of the astronaut, W = 200 N

acceleration due to gravity on moon, g = 1.62 m/s²

Apply Newton's second law of motion to determine the mass of the astronaut;

F = ma = mg

m = F/g

m = 200 / 1.62

m = 123.457 kg

The weight of the astronaut on Earth is calculated as follows;

F = mg

where;

g is acceleration due to gravity on Earth = 9.8 m/s²

F = 123.457 x 9.8

F = 1209.88 N

Therefore, the weight of the astronaut on Earth is 1209.88 N

Answer:

120N

Explanation:

Newton's second law formula: F= ma

given that m = 10 kg, a = 12 m/s^2

F = ma = 10 kg * 12 m/s^2 = 120 kgm/s^2 = 120 N

The force acting on the box is equal to 120N. Therefore, option (A) is correct.

According to Newton's 2nd law of motion, The force acting on an object is equal to mass times the acceleration of that object.

This law tells that the acceleration of a moving body depends upon two variables in which one is the mass of the object which is constant while the other is the force acting on that object. The acceleration of an object increases as the mass of the object is less.

The mathematical equation of the second law of motion can be written as:

F = ma

Given, the mass of the box, m = 10 Kg

The acceleration of the box, a = 12m/s²

We can find the force acting on the box by putting the values a and m:

Force acting on the box, F = 10 ×12 = 120 N

Therefore, the force acting on the box is equal to 120 newtons.
