Answer:

The correct option is 'd': The change in shape of an object.

Explanation:

Since by definition physical change is defined as a change that changes only the form of an object or substance and producing no change in the chemical composition of the substance. Physical changes are reversible in nature.

As we can see from all the options the change in the shape of the object is a reversible change as we can always remold any substance in any shape, thus it confirms to a physical change.

The change in the molecular composition of an object is a hallmark of a chemical reaction thus indicates a chemical change.

The smell change in an object is an indication of a chemical change in the object hence is not a physical change.

Calculate the required rate of return for Climax Inc., assuming that (1) investors expect a 4.0% rate of inflation in the future

Westkost [7]

Answer:

Required rate of return = 18.5 %

Explanation:

given,

rate of inflection = 4 %

risk free rate = 3 %

market risk premium = 5 %

firm has a beta = 2.30

rate of return has averaged 15.0% over the last 5 years

now,

Nominal risk free rate = risk free rate + inflation

= 3% + 4%

= 7%

Required rate of return = Nominal risk free rate + β (RPM)

= 7% + 2.3 x 5.0%

Required rate of return = 18.5 %

grandymaker [24]

The unit of force is the 'Newton'.

1 newton is the force that accelerates 1 kilogram of mass
at the rate of 1 meter per second-squared.

1 N = 1 kg-m/s²

-- A force of 1 pound is about 4.448 newtons.

-- A force of 1 newton is about 3.6 ounces.

vlabodo [156]

Answer:

V = 156.13 [cm³]

Explanation:

El volumen de un solido con forma de paralepipedo se puede calcular por medio de la siguiente formula:

$V = ancho*largo*alto$

donde:

V = volumen [cm³]

ancho = 3.4 [cm]

largo = 11.2 [cm]

alto = 4.1 [cm]

Ahora reemplazando.

$V = 3.4*11.2*4.1\\V = 156.13 [cm^{3}]$

IrinaK [193]

The reasoning which is in use when large, angular rocks are interpreted to have originated from the outcrop at the top of the hill is; Fossil succession

<h3>Fossil succession of rocks</h3>

The principle of fossil succession in characterized by the fact that fossil entities succeed one another upward through rock layers in a definite and determinable order.

On this note, any time period can be dated by its fossil content.
