The temperature of a fluid rises when energy is given to it. This phenomenon can be described by the equation:

Q = MCp ΔT

where,

Q is the quantity of added energy.

M is the fluid's mass.

The fluid's heat capacity is denoted by Cp.

T stands for temperature change.

<h3>What happens to a fluid's kinetic energy as the temperature rises?</h3>

The mean kinetic energy of the particles in a liquid rises with temperature. The molecules' higher average kinetic energies allow them to more easily overcome the attraction forces that keep them bound together.

<h3>Which temperature rise makes liquids more fluid?</h3>

The most significant determining factor for fluidity is pouring temperature. Therefore, the fluidity increases as the pouring temperature increases.

<h3>How does a liquid react when the temperature rises?</h3>

Particles in a solid, liquid, or gas move more quickly as its temperature rises. The particles slow down as the temperature drops. When a liquid is sufficiently cooled, it turns into a solid.

Large electric fields in cell membranes cause ions to move through the cell wall. The field strength in a typical membrane is 1.

jeka57 [31]

Answer:

$1.6\cdot 10^{-12}N$

Explanation:

The electric force on a charged particle is given by

$F=qE$

where

q is the charge of the particle

E is the strength of the electric field

In this problem, we have

$E=1.0\cdot 10^7 N/C$ is the electric field strength

$q=+e=+1.6\cdot 10^{-19}C$ is the charge of the calcium ion

Therefore, the electric force exerted on the calcium ion is

$F=(1.6\cdot 10^{-19}C)(1.0\cdot 10^7 N/C)=1.6\cdot 10^{-12}N$

A 3,65 kg mass attached to a

motikmotik

This question involves the concepts of tension, weight, and centripetal force.

The maximum speed, the mass can have before the string breaks is "10.26 m/s".

First, we will find the maximum tension force:

Tension = Weight

T = W = mg = (32.4 kg)(9.81 m/s²)

T = 317.84 N

Now, this tension force must be equal to the centripetal force:

$T = \frac{mv^2}{r}\\v=\sqrt{\frac{Tr}{m}}$

where,

v = maximum speed = ?

r = radius = 1.21 m

m = mass = 3.65 kg

Therefore,

$v=\sqrt{\frac{(317.84\ N)(1.21\ m)}{3.65\ kg}}\\$

A kilogram is a unit of mass and when multiplied by meters per second

amm1812

Answer:

it yields a derived unit known as Newton, which is the unit of Force.

Explanation:

The formula for force is given by Newton's Second Law, which states that whenever an unbalanced force is applied to a body, it produces an acceleration in the body in the direction of force.

$F = ma\\$

where, F = Force

m = mass

a = acceleration

Now, we substitute the respective S.I units of each quantity in equation:

F = Newton (N)

m = kilogram (kg)

a = acceleration = m/s²

Therefore,

$N = (kg)(m/s^2)$

So, it is clear from above expression that:

<u>When kilogram is multiplied by meter per second squared, it yields a derived unit known as Newton, which is the unit of Force.</u>

Answer:

sound energy is form of mechanical energy.Sound travels as waves of energy, but, unlike light, the waves transmit energy by changing the motion of particles. ... That means that each individual particle is only moving a short distance.
