compressibility, pressure, buoyancy, viscosity, and surface tension are characteristic of a fluids.
What is fluid ?Fluid is a material which can flow. gas and liquid is called as fluid. If a fluid is not compressible and it has zero viscosity it is considered an ideal fluid.
Fluids have no definite shape.
it has many characteristics,
Compressibility, different fluids have different compressibility, only gas is compressible, liquids are incompressible.
Pressure - all flued have pressure associated with them, when a gas is enclosed in a box, gas molecule have kinetic energy which collides on the wall of the box and pressurize it. Flowing water have pressure.
buoyancy - when a small object is falling in the flued a force called buoyance force is acted upon it which opposes falling motion.
Viscosity - it is relative motion between two adjacent layer, each liquid has different viscosity.
surface tension - it is the force per unit tangential line on the region which acts as stretched membrane.

Or
Does distance effect the strength of attraction more than magnitude?
Explanation:
Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects. And decreasing the separation distance between objects increases the force of attraction or repulsion between the objects.

An 80.0 kg merry-go-round of radius 1.20 m is accelerating horizontally from rest by a constant force of 70.0 N applied tangentially to the merry-go-round. Find the kinetic energy of the merry-go-round after 5.00 s. (Assume it is a solid cylinder.)
The kinetic energy of the merry-go-round after 5.00 s, when a constant force is applied tangentially to it, is determined as 3,069.5 J.
Conservation of angular momentumThe kinetic energy of the merry-go-round is determined by applying the principle of conservation of angular momentum as follows;
Iα = rF
where;
I is moment of inertia of the merry-go-round (solid cylinder)I = ¹/₂mr²
I = ¹/₂ x 80 x (1.2)²
I = 57.6 kgm²
α = (rF)/I
α = ( 1.2 x 70) / (57.6)
α = 1.46 rad/s²
Tangential acceleration of the merry-go-rounda = αR
a = 1.46 x 1.2
a = 1.752 m/s²
Velocity of the merry-go-roundThe velocity of the merry-go-round after 5 s is calculated as follows;
v = u + at
v = 0 + (1.752x 5)
v = 8.76 m/s
Kinetic energy of the merry-go-roundK.E = ¹/₂mv²
K.E = ¹/₂ x 80 x 8.76²
K.E = 3,069.5 J

brainly an andean condor with a wingspan and a mass soars along a horizontal path. model its wings as a rectangle with a width. determine the difference between the pressure at the top surfaces of the condor's wings and the pressure at the bottom surfaces brainly
The difference between the pressure at the top surfaces of the condor's wings and the pressure at the bottom surfaces is 101,204 Pa.
Difference in pressure between the top and bottom of the wingspanThe difference in pressure between the top and bottom of the wingspan is calculated as follows;
ΔP = P(top) - P(bottom)
Area of the wingspanA = bh
A = 2.7 m x 0.27 m
A = 0.729 m²
Weight of the Andean condorW = mg
W = 9 x 9.8
W = 88.2 N
Pressure at the top surface of condor's wingsThe pressure at the top surface of condor's wings is due to atmospheric pressure
P(top) = 14.7 Psi = 101,325 Pa
Pressure at the bottom surface of condor's wingsThe pressure at the bottom surface is due to weight of andean condor.
P = W/A
P(bottom) = 88.2/0.729
P(bottom) = 120.99 Pa
The difference between the pressure at the top surfaces of the condor's wings and the pressure at the bottom surfaces is calculated as;
ΔP = P(top) - P(bottom)
ΔP = 101,325 Pa - 120.99 Pa
ΔP = 101,204 Pa

A 8.2 kg solid sphere, made of metal whose density is 2300 kg/m3, is suspended by a cord. When the sphere is immersed in a liquid of unknown density, the tension in the cord is 23 N. The density of the liquid is
The density of the liquid is 1470.43 kg/m³. Density is an important parameter in order to understand the fluid and its properties. Its unit is kg/m³.
What is density?Density is defined as the mass per unit volume. The mass and density relation is given as;
mass = density × volume
The given data in the problem is as ;
m is the mass of a solid sphere=8.2 kg
[tex]\rm \rho_s[/tex] is the density of the metal= 2300 kg/m³
T is the tension in the cord = 23 N.
The volume of the liquid is found as;
[tex]\rm V_{sphere} = \frac{m}{\rho} \\\\ \rm V_{sphere} =\frac{8.2}{2300} \\\\ \rm V_{sphere} = 0.00356 \ m^3[/tex]
The volume of the sphere is equal to the volume displaced;
Volume displaced = 0.00356 m³
The buoyant force is found as;
[tex]\rm F_B = \rho g V \\\\[/tex]
From the given condition it is observed that the weight of the sphere is equal to the sum of buoyancy force and the tension in the cord.
[tex]\rm mg = \rho g V+T \\\\ 8.2 \times 9.81 = \rho \times 9.81 \times 0.00356+23 \\\\\ 80.442=\rho \times 0.0349 +23 \\\\ \rho = 1645.90 \ kg/m^3[/tex]
Hence the density of the liquid is 1645.90 kg/m³.

A 3.0-kg block moves up a 40° incline with constant speed under the action of a 26-N force acting up and parallel to the incline. What magnitude force must act up and parallel to the incline for the block to move down the incline at constant velocity?
Explanation:
Sooooo, first,
Constant Speed means that the body isn't accelerating.
a= 0
Let the force that causes it to move up the incline be P and Q be the force that causes the body to move down the incline. Let Fr be the frictional force.
The force that pulls the body downwards is given by,
F = mgsin40°
F= 18.898N
P -(F+Fr) = ma, but, a= 0
P = F + Fr
Fr = 26-18.898
= 7.102N
If the block must move down the incline, Q and Fr will act in the same direction.
Q + Fr = F
Q = 11.796N

A bullet having the mass of 110g is fired. If it's velocity is 50m/s, calculate the kinetic energy
[tex]\text{Kinetic energy,}\\\\E_k = \dfrac 12 mv^2\\\\~~~~~=\dfrac 12 \cdot 110 \times 10^{-3} \cdot 50^2\\\\~~~~~=137.5~ \text{J}[/tex]
Answer: 137.5 Joules
Explanation:
The SI units for kinetic energy is Joules, the SI units for mass is kilograms, and the SI units for velocity is meters per second. We are given the mass in grams, so we must convert it to kilograms. There are 1,000 grams in 1 kilogram:
[tex]110g*\frac{1kg}{1000g} =0.11kg[/tex]
Kinetic energy is the energy the system has due to its motion. It is defined to be:
[tex]KE=\frac{1}{2} mv^2[/tex]
Plug everything in:
[tex]KE=\frac{1}{2} (0.11kg)(50m/s)^2[/tex]

the battery voltage?
Express your answer in seconds (s)
The time taken for the capacitor voltage to be 45 % of the battery voltage is 5,750.3 s.
Discharge of the capacitor voltage
The rate at which the capacitor voltage discharges is given by the following formula;
