Considering the definitipn of current, voltage, power, and Ohm's law,
CurrentThe flow of electricity through an object, such as a wire, is known as current (I). Its unit of measurement is amps (A). So current is a measure of the speed at which the load passes through a given reference point in a specified direction.
VoltageThe conductive force (electrical pressure) behind the flow of a current is known as voltage and is measured in volts (V) (voltage can also be referred to as the potential difference or electromotive force). That is, voltage is a measure of the work required to move a charge from one point to another.
Resistance
Resistance (R) refers to the resistance or opposition that an element has to the passage of electric current. It is represented by the symbol Ω and indicates the resistance that an element offers to the passage of electricity.
This means that the greater the resistance to the passage of current, the lower the intensity or amount of electricity that passes through this conductor.
The resistance that is measured in ohms.
Ohm's law
Ohm's law indicates that the current through a circuit is directly proportional to its voltage or voltage and inversely proportional to the resistance it presents.
Mathematically, Watt's law is expressed:
[tex]I=\frac{V}{R}[/tex]
So if you want to find resistance, the expression for its calculation is:
[tex]R=\frac{V}{I}[/tex]
This caseIn this case, you know:
V= 5.26 VI= 0.41 AReplacing:
[tex]R=\frac{5.26 V}{0.41 A}[/tex]
Solving:
R= 12.8 ohms
Habiba is right. The resistance is 12.8 ohms.

WHAT IS THE VOLUME OF A 5.71 G PLASTIC CUBE THAT HAS A DENSITY OF 1.15 G/CM3
DONT ANSWER i need to find out if it cant float or sink?!
Answer:
p>Whether an object will float or sink is dependent on its density, and on the density of the liquid it is placed in. In the case of water, an object with a density less than 1 g/cm3 will float. The closer its density is to 1 g/cm3, the more of it will sit below the water level.

Answer:
KE = 0.5 * m * v², where: m - mass, v - velocity.
Explanation:
In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s 2.

49.4 m.
The maximum height reached by the ball during the upward motion is 24.7 m.
The given parameters;
initial velocity of the ball, u = 22 m/sThe maximum height reached by the ball is determined using the third kinematic equation as shown below;
v² = u² - 2gh
where;
v is the final velocity of the ball at the maximum height = 0h is the maximum height attained by the ball0 = u² - 2gh
2gh = u²
[tex]h = \frac{u^2}{2g} \\\\h = \frac{22^2}{2(9.8)} \\\\h = 24.7 \ m[/tex]
Thus, the maximum height reached by the ball during the upward motion is 24.7 m.

Three forces act simultaneously on poin J. One force is 10.0 N north; the second is 15.0 N west; the third is 15.0 N 30.0° east of north. Determine the magnitude and direction of the resultant force.
The magnitude and direction of the resultant force are 10.0N and 101.36⁰
The sum of force along the force horizontal is expressed as:
[tex]\sum F_x=-15.0N+15cos30\\\sum F_x = -15.0N + 12.99N\\\sum F_x = -2.01N[/tex]
The sum of force along the vertical is expressed as:
[tex]\sum F_y = +10N[/tex]
Calculate the magnitude of the force:
[tex]F=\sqrt{(\sum F_x)^2+(\sum F_y)^2} \\F=\sqrt{(-2.01)^2+(10)^2} \\F=\sqrt{104.0401}\\F= 10.2N[/tex]
Hence the magnitude of the resultant force is 10.2N
Find the direction
[tex]\theta = tan^{-1}\frac{y}{x}\\ \theta = tan^{-1}\frac{10}{-2.01}\\\theta =tan^{-1}(-4.9751)\\\theta =-78.63^0\\\theta = 180-78.63 = 101.36^0[/tex]
Hence the magnitude and direction of the resultant force are 10.0N and 101.36⁰

3. Explain what forces the Egyptians had to overcome when building the pyramids
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
But how did the Egyptians overcome the extreme friction of dragging such massive things through the sandy desert, some of which weighed more than 9,000 pounds? Researchers at the University of Amsterdam have come up with a very simple solution to the friction problem: they utilised water.
The pyramids were not built by slaves, contrary to common perception. Archaeologists discovered the ruins of a purpose-built town for the hundreds of labourers who constructed the renowned Giza pyramids about 4,500 years ago.
The Egyptians had to overcome the force of friction while dragging the big blocks of stone and the force of gravity while uplifting the large stone structure to a greater height when building the pyramids.
What is friction?Friction is a type of force that resists or prevents the relative motion of two physical objects when their surfaces come in contact.
The friction force prevents any two surfaces of objects from easily sliding over each other or slipping across one another. It depends upon the force applied to the object.
Thus, while constructing the pyramids, the Egyptians had to fight against the forces of gravity and friction as they lifted the massive stone edifice to a greater height.

A ship travels 3.20 hours with a velocity of 21.1 mph at theta= 123º, including the effects of the
current. The pilot then turns to a heading of 190.0° with a speed of 18.2 mph, including the effects of
the current. If the pilot stays on this heading for 1.10 hours, what is the ship's final displacement from
its original starting point?
The vector addition and kinematics of uniform motion allows to find the result for where the starting point is:
The ship left a point at a distance of 77,565 miles in a direction of 136.7º from the x-axis.
Given parameters
First speed v₁ = 21.3 pH Angle θ₁ = 123º Time t₁ = 3.20 h Second speed v₂ = 18.2 mph Angle θ₂ = 190.0º Time t₂ = 1.10 hTo find
Distance start point.
Velocity is a vector magnitude, therefore it has direction and module, to make the addition of these magnitudes vector algebra must be used.
There are two methods for adding vectors:
Graphic. In this case, a vector is placed at the tip of the other and the resulting vector goes from the origin of the first to the tip of the last. Analytical. In this case, the vector is decomposed into a coordinate system, the resultants are found and the vector is composed.
In the attached we can see a diagram of the displacement of this ship. We use a Cartesian reference system and using trigonometric to decompose the velocities.
First speed
cos 123 = [tex]\frac{v_1_x}{v_1}[/tex]
sin 123 = [tex]\frac{v_1_y}{v_1}[/tex]
v₁ₓ = v₁ cos 123
[tex]v_{1y}[/tex] = v₁ sin 123
v₁ₓ = 21.1 cos 123 = -11.49 mph
[tex]v_{1y}[/tex] = 21.1 sin123 = 17.70 mph
Second speed
v₂ₓ = v₂ cos 190
[tex]v_{ 2y}[/tex] = v₂ sin190
v₂ₓ = 18.2 cos 190 = -17.92 mph
[tex]v_{2y}[/tex] = 18.2 sin190 = -3.16 mph
Now we can use kinematics of uniform motion.
v = [tex]\frac{d}{t}[/tex]
d = v t
Where v is the velocity, d the distance and t the time
Let's find every distance traveled.
For first speed
x-axis
x₁ = v₁ₓ t₁
x₁ = -11.49 3.20
x₁ = - 36,768 miles
y-axis
y₁ = [tex]v_{1y} \ t_1[/tex]
y₁ = 17.70 3.20
y₁ = 56.64 miles
Travel for 2nd speed
x₂ = v₂ₓ t₂
x₂ = -17.92 1.10
x₂ = -19,712 miles
y₂ = -3.16 1.10
y₂ = - 3,476 miles
Let's find the distance traveled on each axis
x-axis
[tex]x_{total}[/tex] = x₁ + x₂
[tex]x_{total}[/tex] = -36,768 - 19,712
[tex]x_{total}[/tex] = -56.48 miles
y-axis
[tex]y_{total}[/tex] = y₁ + y₂
[tex]y_{total}[/tex] = 56.64 - 3.476
[tex]y_{total}[/tex] = 53,164 miles
Let's construct the total displacement vector, for the module let's use the Pythagorean theorem
[tex]d_{total} = \sqrt{x^2 +y^2} \\d_{total} = \sqrt{56.48^2 +53.164^2}[/tex]
[tex]d_{total}[/tex] = 77,565 miles
Let's used trigonometry for the direction
[tex]tan \theta ' = \frac{y_{total} }{ x_{total} } \\\theta ' = tan^{-1} \frac{y_{total} }{ x_{total} }[/tex]
θ’= 43.3º
This angle is in the second quadrant to indicate the angle with respect to the positive side of the x-axis in a counterclockwise direction.
θ = 180 - θ'
θ = 180 - 43.3
θ = 136.7º
In conclusion using the addition vectors and kinematics of uniform motion we can find the result for where the starting point is:
The ship left a point at a distance of 77,565 miles in a direction of 136.7º from the x-axis.

Which statement best describes the main idea of the poem
Two roads diverged in a yellow wood, And sorry I could not travel both And be one traveler, long I stood And looked down one as far as I could To where it bent in the undergrowth; Then took the other, as just as fair, And having perhaps the better claim, Because it was grassy and wanted wear; Though as for that the passing there Had worn them really about the same, And both that morning equally lay In leaves no step had trodden black. Oh, I kept the first for another day! Yet knowing how way leads on to way, I doubted if I should ever come back. I shall be telling this with a sigh Somewhere ages and ages hence: Two roads diverged in a wood, and I— I took the one less traveled by, And that has made all the difference.
