The liquid with greater thickness will be more viscous since it flow speed is lower. Therefore, the more thick liquids is more viscous and flow slowly.
What is viscosity ?Viscosity of a liquid is the resistance to its flow. Viscosity depends on the density and thickness of the liquid. The more thicker the liquid the more viscous it will be.
Less thick liquids will flow fastly. For example water is a less viscous liquid as we see it flow so quickly. Whereas, honey, oil, etc are more viscous and the mobility of their liquid particles are resisted by viscosity.
The more viscous liquids generally has higher specific heat capacity as in the case of water and oil. The particle - particle attractive force is higher in highly viscous liquids.

what the kinetic energy quantities in calculation pls help me
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.
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

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.

because when you fire the cannon the cannon ball and powder exit the cannon then that leaves the cannon ball and i would say that the explosion would force it out the cannon but would not increase its mass.

Describe the relationship between the state of matter of water (gas, liquid, solid) and the motion of the water molecules.
Answer:
ok
Explanation:
solid- molecules are close together and vibrating
liquid - molecules are loser, faster moving and take the shape of its container
gas- fast moving molecules and take whatever shape they want (like a room or the air outside)
Explanation:
Solids: The inter-molecular attraction force is the highest and the inter-molecular distance is the least. Solids have definite shape and volume.
Liquids: The inter-molecular attraction force is less than that of solids and the inter-molecular distance is more than solids. Liquids have definite volume but no definite shape.
Gases: The inter-molecular attraction force is the least and the inter-molecular distance is the highest. Gases have no definite shape or volume.
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.

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.
