Answer:

__3__ blood picks up waste products such as carbon dioxide

__2__ carries oxygen and nutrients to the body cell

__1__ moves to right ventricle and to lungs

__4__ blood travels from the lungs to the left atrium

__5__ returns to right atrium

Explanation:

PLS MARK BRAINLEST

Both vena cava passes the deoxygenated blood to the right atrium. Blood from right atrium enters right ventricle and pulmonary arteries carry deoxygenated blood from right ventricle to lungs for oxygenation. Two pulmonary veins come from each lung and pass O2 -rich blood to left atrium. Blood enters left ventricle from the left atrium. The left ventricle pumps blood into the aorta which in turn branches and delivers blood to the major body regions and organs.

Answer:

[tex]15\:\mathrm{J}[/tex]

Explanation:

The potential energy of an object is given by [tex]PE=mgh[/tex].

Recall that the weight of an object is equal to the force of gravity on the object. From this, we can set up the following equation and solve for the mass of the object:

[tex]F=mg,\\5=mg,\\m=\frac{5}{9.81}\approx 0.51\:\mathrm{kg}[/tex]

Now we can plug in values to [tex]PE=mgh[/tex] and solve:

[tex]PE=0.51\cdot9.81\cdot3=\fbox{$15\:\mathrm{J}$}[/tex].

Answer:

The potential energy of the body is 15J.

Explanation:

The energy possessed to a body due to position is called Potential energy.

U=mgh

U=mgh

U=5×3=15J

Hence, the potential energy of the body is 15J.

Answer:

The object has an approximate mass of 4.06 kilograms.

Explanation:

Force is equal to mass times acceleration, so all we need to do is divide the force provided by the acceleration provided.

[tex]m = \frac{62.2N}{15.3 \frac{m}{s^2}}\\\\m = \frac{62.3kg\frac{m}{s^2}}{15.3 \frac{m}{s^2}}\\\\m = \frac{62.2kg}{15.3}\\\\m = 4.06kg[/tex]

Answer:

Negative feedback caused his pancreas to produce more insulin.

Explanation:

Positive feedback is a feedback that causes an increase of product as a result of change while negative feedback is a feedback that causes a decrease in product as a result.

Negative feedback mechanism can be shown in the body as the control of blood sugar. The blood sugar is the product to be controlled. When there is an increase in blood sugar, the nerves sense a change. This change leads to secretion of insulin by the pancreas until homeostasis and then the secretion stops.

Answer:

negative feedback cause his pancreas to stop secreting insulin.

B. The Law of Conservation of Energy

Explanation:

In Science, energy can be defined as the ability of an object or body to do work. There are two (2) main types of energy and these are;

I. Kinetic energy: it can be defined as an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

Where, K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents velocity measured in metres per seconds square.

II. Potential energy: it can be defined as an energy possessed by an object or body due to its position.

Mathematically, potential energy is given by the formula;

Where, P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

Additionally, the various forms of energy are solar energy, electrical energy, chemical energy, thermal energy, wind energy, nuclear energy etc.

Hence, energy is never created of destroyed, it only transforms from one form to another" is the definition of The Law of Conservation of Energy.

Answer:

The resistance provided by the electrical elements is;

D. 0.375 Ohms

Explanation:

The relationship between the voltage, V, current, I, and resistance, R of an electric circuit is given as follows;

V = I × R

The given parameters of the circuit are;

The voltage provided by the car battery, V = 12 V

The current drawn by the air conditioning and lights, I = 32 A

From, V = I × R, we have;

R = V/I

Therefore, by substituting the known values, we have;

R = 12 V/(32 A) = 0.375 Ohms

The resistance provided by the electrical elements, R = 0.375 Ohms

Answer:

Acceleration = 0.5 m/s²

Explanation:

Given the following data;

Initial velocity, u = 1m/s

Final velocity, v = 3m/s

Time, t = 4 seconds

To find acceleration;

In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.

This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.

Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.

Mathematically, acceleration is given by the equation;

[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]

[tex]a = \frac{v - u}{t}[/tex]

Substituting into the equation, we have;

Acceleration = (3 - 1)/4

Acceleration = 2/4

Acceleration = 0.5 m/s²

The [x] component will be +57.47 a[x]  and the [y] component will be -30.51 a[y].

Any vector can be resolved along the axes of the cartesian coordinate system. For a two dimensional vector (say [V]), it can be resolved along the

[x] and [y] axis, such that the components of the vector are the vector's themselves and are given by -

[x] component = VcosФ a[x]

[y] component = VsinФ a[y]

Given is a vector is drawn on an X - Y plane. It has a magnitude of 65.1 centimeters and a direction of 28.0 degrees below the positive x-axis.

From the data given, we can write -

Magnitude of vector = |V| = 65.1

Angle made with +x axis = [Ф] =28 degrees {below the axis}

Therefore, the [x] component will be -

[x] = 65.1 x cos(28) = 57.47 a[x]

and the [y] component will be -

[y] = 65.1 x sin(28) = 30.51 × -a[y] = -30.51 a[y]

Therefore, the [x] component will be +57.47 a[x]  and the [y] component will be -30.51 a[y].

Explanation: The absorption of light makes an object dark or opaque to the wavelengths or colors of the incoming wave: Wood is opaque to visible light. Some materials are opaque to some wavelengths of light, but transparent to others. Glass and water are opaque to ultraviolet light, but transparent to visible light.

Option.D-All materials is the correct answer.
Any object, whether living or inert, has the ability to absorb light. Absorption is always influenced by the electromagnetic frequency of the light being transmitted (i.e., its color) and the composition of the object's atoms.

.(b) the two walls are silvered to minimise the heat loss by radiation , because a shiny surface is a bad absorber and bad emitter of radiation i.e. good reflector of heat , so prevents the heat exchange between content of flask and surrounding .
