How the choice of building materials and techniques can help them cool down faster, after heating up.

Answers

Answer:

The choice of building materials and techniques can help them cool down faster, after heating up is explained below in brief details.

Explanation:

Building materials

Buildings that are composed of rock, bricks, or pavement, or inserted into the territory, can seem cooler thanks to the great "thermal mass" of these elements – that is, their capability to assimilate and discharge heat gently, thereby softening temperatures over time, producing daytime cooler and night-time warmer.

last question, can someone help please?

Answers

Answer may very but include: The terminal velocity of an object falling through a fluid is its maximum attainable velocity in the fluid. it is said to occur when the sum of the drag force and the buoyancy is equal to the downward force of gravity acting on the object. At terminal velocity, the object stops accelerating and moves at constant velocity.

What happens to the arrangement of atoms in matter as it is heated?

Answers

Answer:

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance.

Explanation:

Atoms speed up and create more energy/heat.

A box of mass 5.0 kg is initially at rest. A 500 N force causes it to move horizontally through a
distance of 12.00 m. How much work would there be?

Answers

Answer:

Workdone = 6000Nm

Explanation:

Given the following data;

Mass = 5kg

Force = 500N

Distance = 12m

To find the work done;

Workdone = force * distance

Workdone = 500 * 12

Workdone = 6000Nm

Empujamos un baúl 3 metros, para ello aplicamos una fuerza de 200 Newton. ¿Cuál es el trabajo realizado?

Answers

Answer:

Trabajo realizado = 600 Nm

Explanation:

Dados los siguientes datos;

Fuerza = 200 Newton

Distancia = 3 metros

Para encontrar el trabajo realizado; Trabajo realizado = fuerza * distancia

Sustituyendo en la ecuación, tenemos; Trabajo realizado = 200 * 3

Trabajo realizado = 600 Nm

Which of these statements is true about the effect of a force exerted upon an object?
a. A large force always produces a large change in the object's momentum.
b. A small force always produces a large change in the object's momentum.
c. A small force applied over a long time interval can produce a large change in the object's momentum.
d. A large force produces a large change in the object's momentum only if the force is applied over a very short time interval.

Answers

Answer:

d. A large force produces a large change in the object’s momentum only if the force is applied over a very short time interval.

Explanation:

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.

Mathematically, momentum is given by the formula;

[tex] Momentum = mass * velocity [/tex]

Also, the impulse of an object is given by the formula;

[tex] Impulse = force * time [/tex]

In accordance with the impulse-momentum theorem, the statement which is true about the effect of a force exerted upon an object is that a large force produces a large change in the object’s momentum only if the force is applied over a very short time interval.

Calculating net force

Answers

Answer:

0N.

Explanation:

Net force is the sum total of forces acting on an object.

The Fn which is the net force is

450+ (-250) + (-600)+ 600+ 0 + 250 + (-450)

= 450-250+(-600)+ 600+0+250-450

= 0N

The net force is 0

Explanation: Hand span is not a standard unit.

Second is the unit of time.

Meter is the unit of length or distance covered by an object.

Gram is the unit of weight of an object.

Hand span is not a standard unit. This is because the size of hand varies from person to person. Hence, the correct option is (c) "hand span".

An automobile of mass 1.46 E3 kg rounds a curve of radius 25.0 m with a velocity of 15.0 m/s. The
centripetal force exerted on the automobile while rounding the curve is:

Answers

Answer:

Centripetal force = 13140 Newton.

Explanation:

Given the following data;

Mass = 1.46 E3 kg = 1.46*10³ = 1460 kg

Velocity = 15m/s

Radius, r = 25m

To find the centripetal force, we would use the following formula:

Centripetal force = mv²/r

Substituting into the equation, we have;

Centripetal force = (1460*15²)/25

Centripetal force = (1460 * 225)/25

Centripetal force = 328500/25

Centripetal force = 13140 Newton.

29. A wave source approaches your location, describe
the shift in wavelength and frequency you will
perceive.

Answers

Answer:

The waves travel at the same speed, but the observed frequency depends on any relative motion between the observer and source. When the observed frequency changes, so does the wavelength. If the observer and source are moving toward each other, then the frequency increases and the wavelength decreases.

A weightlifter lifts a set of weights a vertical distance of 2.0 m. If a constant net force of 350 N is exerted on the weights, what is the net work done on the weights?

Answers

Answer:

700 Joules

Explanation:

The work done equals force times distance. Just multiply your two values there.

Side note: It would be more impressive if he'd done it in 1 second rather than 5. You know why? Because POWER=WORK/TIME. The less time it takes him to lift the weight with the same force and distance, the more powerful he is!

14. Saeed is pulling a 6 kg heavy rock with an upward force of 40 N but does not succeed to lift it up. What is the magnitude of the normal force on the rock?

Answers

Answer:

58.8 N

Explanation:

The normal force is calculated as equal to the perpendicular component of the gravitational force.

Thus; N = mg

We are given m = 6 kg

Thus;

N = 6 × 9.8

N = 58.8 N

Thus, magnitude of normal force on the rock = 58.8 N

PLS mark BRAINLIEST

A wagon of mass 42 kg is pushed by a student a distance of 12.2 meters, and 297 j of work was done on the wagon force did the student apply is 24.34 N.

What is force?

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

work = force*distance

force = work/distance

force = 297/12.2

force = 24.34 N

For an object falling at the terminal velocity, list all the forces (magnitude and direction) acting it?

Answers

Answer:

Three stages of falling

There are three stages as an object falls through a fluid:

at the start, the object accelerates downwards due to the force of gravity

as the object's speed increases, frictional forces such as air resistance or drag increase

at terminal velocity, the weight of the object due to gravity is balanced by the frictional forces, and the resultant force is zero
