an adult has suffered a diabetic emergency. first aid care was given, but the person continues to not feel better. when should you call 9-1-1?

The commonly expressed equation to describe Newton's second law of motion is F = m×a.

Newton's second law of motion states that the acceleration of an object is directly proportional to the force applied to it, and inversely proportional to its mass.

Mathematically, this can be expressed as F = ma, where F is the net force applied to an object, m is the object's mass, and a is the resulting acceleration of the object.

In other words, the greater the force applied to an object, the greater its acceleration will be, and the more massive the object is, the less its acceleration will be for a given force.

This law is one of the fundamental principles of classical mechanics and is essential for understanding the behavior of objects in motion.

Thus the distance between the man and his image is now 3+3 = 6 cm.

Answer:

40 kW

Explanation:

A railcar has a continuous 1000 N decelerating force any time it is in motion. If no braking occurs, how much power would be required to keep the railcar moving at 40 m/s

Solution:

Power in Physics is the rate of doing work and the work can be mechanical, electrical, etc. The S.I unit of power is the watts (W).

The power required to keep the car moving must match the work done by the friction force (decelerating force) that tends to slow down the railcar.

Work done = Force * displacement

Power = Work done / time = (Force * displacement) / time

Power = Force * (displacement / time)

Power = force * velocity = 1000 N * 40 m/s = 40000 W

Power = 40 kW

Answer:

La velocidad del sistema bala-bloque es 5 metros por segundo.

Explanation:

El enunciado tiene una omisión gramatical. La forma correcta es la siguiente:

Una bala de 0.8 kilogramos de masa se mueve horizontalmente con una velocidad de 30 metros por segundo y se introduce en un bloque de 4 kilogramos, inicialmente en reposo. ¿Cuál es la velocidad de la bala y el bloque después del impacto?

Esta situación es un caso clásico de colisión enteramente inelástica, en donde el sistema bala-bloque no tiene influencia de fuerzas externas, entonces la situación queda descrita por la siguiente ecuación:

\(m_{b}\cdot v_{b,o} = (m_{b}+m_{B})\cdot v\) (1)

Donde:

\(m_{b}\) - Masa de la bala, en kilogramos.

\(v_{b,o}\) - Velocidad inicial de la bala, en metros por segundo.

\(m_{B}\) - Masa del bloque, en kilogramos.

\(v\) - Velocidad del sistema bala-bloque, en metros por segundo.

Si sabemos que \(v_{b,o} = 30\,\frac{m}{s}\), \(m_{b} = 0.8\,kg\) y \(m_{B} = 4\,kg\), entonces la velocidad del sistema masa-bloque es:

\(v = \frac{m_{b}}{m_{b}+m_{B}}\cdot v_{b,o}\)

\(v = 5\,\frac{m}{s}\)

La velocidad del sistema bala-bloque es 5 metros por segundo.

Explanation:

tan ● = opposite / adjacent

tan 31.5 = 19 / F

0.613 = 19 / F

0.613F = 19

F = 31

sin ● = opposite / hypotenuse

sin 31.5 = 19 / a

0.52 = 19 / a

0.52a = 19

a = 36. 36

Using trigonometry, the base of the triangle is approximately 33.476, and the hypotenuse of the triangle is approximately 38.118.

To find the base and hypotenuse of a right triangle with one angle of 31.5 degrees and a given height of 19:

Here,

Opposite side = height = 19 (given)

Adjacent side = base (unknown)

Hypotenuse = hypotenuse (unknown)

First, let's find the base (adjacent side):

tan(θ) = opposite ÷ adjacent

tan(31.5 degrees) = 19/base

To find the base, we can rearrange the equation:

base = opposite ÷ tan(θ)

base = 19 ÷ tan(31.5 degrees)

Calculating the value:

base ≈ 33.476

So, the base of the triangle is approximately 33.476.

Now, using the Pythagorean theorem, we can write:

hypotenuse² = base² + opposite²

hypotenuse² = (33.476)² + 19²

hypotenuse ≈ 38.118

Therefore, the hypotenuse of the triangle is approximately 38.118.

Thus, base is 33.476, and hypotenuse is 38.118.

The conservation of energy and the conservation of angular momentum equations can be used to determine a satellite's velocity and flight-path angle at a 200 km altitude.

The conservation of energy equation can be used first:

E = mv2 (1/2) - GMm/r

E stands for overall energy, m for the satellite's mass, v for its velocity, G for gravitational constant, M for the Earth's mass, and r for its distance from the planet's core. The total energy at 100 km altitude is given by E1 = (1/2)mv1.2 - GMm/. (r1)

where r1 is the distance from the Earth's center at 100 km and v1 is the velocity at 100 km. 200 kilometers above sea level, the total energy

GMm/E2 = (1/2)mv22 (r2)

where r2 is the distance from the Earth's center at 200 km and v2 is the velocity.

GMm/(r1) = (1/2)mv2(r1) - mv1(r2) (r2)

The conservation of angular momentum equation is thus applicable: L = mvr.

L is the angular momentum, m is the satellite's mass, v is its speed, and r is its distance from the Earth's center L1 = mv1r1 represents the angular momentum at an altitude of 100 kilometers.

L2 = mv2r2 represents the angular momentum at an altitude of 200 km.

Answer:

As you increase the temperature of a gas, its particles get more kinetic energy and move faster.

I’ll assume you know what KE is.

Consider a sample of confined gas, liquid, or solid material that’s not going anywhere. We may know it’s mass but since it’s not going anywhere, we conclude the sample has zero velocity and KE is zero.

Long ago it was noticed that a sample like this actually had parts and that they were moving. Each part of the sample had a part of the mass and all those random velocities had a combined Internal KE.

More KE in a particle also carried more momentum. So collisions involved more impulse … to each other and to what ever they touched. This causes more pressure to gas samples, more volume in most liquids and solids.

Put your skin on the surface and your nervous system responds to that impact too. We build devices that survive more extremes than our bodies and report more consistent results. We keep the ones that tend to agree with each others’ response and find those that have use in extreme conditions.

Watching a thermometer reading is a measure of its temperature. The laws of motion predict that the average KE of the device will become the same as its surroundings. An outdoor thermometer may be used to gauge the air temperature; but that is inaccurate when it is also gaining KE by being in sunlight or losing by rain evaporation or snow.

Pepper moves away from dish soap in water due to the disruption of surface tension caused by the interaction between the hydrophobic pepper and the soap molecules. The movement of the paper boat when soap is added is also a result of surface tension, as the soap reduces the cohesive forces between water molecules and creates regions of lower surface tension around the boat, causing it to move.

When pepper is sprinkled onto the surface of water containing dish soap, it disperses and moves away from the soap. This phenomenon is a result of surface tension and the interaction between the soap molecules and the water.

Water molecules have strong cohesive forces, causing them to stick together and create a surface tension. Pepper, being hydrophobic, does not mix well with water and tends to stay on the surface. When dish soap is introduced to the water, it disrupts the surface tension by reducing the cohesive forces between the water molecules.

Soap molecules are composed of a hydrophilic (water-loving) head and a hydrophobic (water-repelling) tail. When soap is added to the water, its hydrophobic tails interact with the water, while the hydrophilic heads face outward. This action disrupts the water's surface tension, creating areas with lower surface tension around the soap molecules.

As a result, the pepper, being hydrophobic, is repelled by the regions of lower surface tension and moves away from the soap. The pepper particles distribute themselves on the water surface away from the dish soap, showcasing the impact of the altered surface tension.

Similarly, when soap is added to a paper boat floating on water, it causes the boat to move. As the soap disrupts the surface tension, it creates regions of lower surface tension around the boat. The water pushes against these areas of lower surface tension, propelling the boat forward.

In summary, the movement of pepper away from dish soap in water is due to the disruption of surface tension caused by the hydrophobic nature of the pepper and the action of soap molecules. Similarly, the addition of soap to a paper boat floating on water creates regions of lower surface tension that push the boat forward.

0.001500 m³ block of titanium would weigh approximately 14.915 pounds.

Density is physical property of matter that explains how much mass is contained in any given volume of a substance and in other words, it is the amount of "stuff" (mass) per unit of space (volume).

We calculate the mass of the titanium block using its density and volume: mass = density × volume

mass = 4510 kg/m³ × 0.001500 m³

mass = 6.765 kg

6.765 kg × (1 pound / 0.453592 kg) ≈ 14.915 pounds

A liquid thermometer can be used to test for fevers. When body temperature increases, the liquid inside the thermometer expands and rises to show a higher temperature reading, the explanation that describes the change in the thermal energy,

The thermometer tip is heated by conduction with the person's body. The particles of the thermometer tip then transfer heat by conduction with the liquid inside of it. The particles inside the liquid then convect heat causing the warmer particles to speed up, expand, and rise.

It can be defined as the form of the energy in which heat is transferred from one body to another body due to their molecular movements, thermal energy is also known as heat energy.

Conduction with the subject's body heats the thermometer's tip. The liquid inside the thermometer is subsequently heated by conduction between the particles of the thermometer tip. The warmer particles then accelerate, expand, and ascend as a result of the heat convecting through the liquid's particles.

recoiling cannon  is the reaction force, indicates newton's third law

In mechanics, every action that tries to preserve, alter, or change a body's motion is referred to as a force. It is common practice to utilize Isaac Newton's three laws of motion to illustrate the idea of force in his Principia Mathematica (1687).

Newton's first law states that in the absence of an external force, a body will continue to be in either its resting or equally moving condition along a straight path. According to the second law, when an outside force applies on a body, the body accelerates (changes velocity) in the force's direction.

If we apply same force  to both-an apple or a couch, the object which will accelerate less is couch.

What is acceleration?

Acceleration is the term used to describe the pace at which speed and direction of velocity vary over time. Something is said to be accelerating when it starts to move faster or slower. Even when the speed is constant, motion on a circle accelerates because the direction is always keeps shifting. Both impacts cause all other motions to speed up.

The couch will accelerate less because

F = m a

where, F = force, m = mass, a = acceleration.

This equation can also be written as

a = F/m
