Resolver: Una bala de 0.8 de masa se mueve horizontalmente con una velocidad de 30 m/s y se introduce en un bloque de 4kg, inicialmente en reposo. ¿Cuál es la velocidad de la bala y el bloque después del impacto?

Answer:

The main reason for this is the engineering and technology driven building construction in Chile than in Haiti

Explanation:

The main reason for this is the engineering and technology driven building construction in Chile than in Haiti. Most of the buildings in Haiti do not fit in the building byelaws norms as most of them were constructed in a short period of time with less engineering and at cheaper rate. While building in Chile were built adhering to the building codes and byelaws.

The base of the building is Chile were separated from each other using the “base isolation” technology and the were also more flexible as compared to the buildings in Haiti.  

The skyscrapers in Chile were constructed in a way that they can float on the arrangements of ball bearings and padded cylinders

Answer:

The correct answer is NONE the two forces must be equal and of opposite direction, the closest answer is D

Explanation:

In this exercise it is indicated that Jack pushes a car, it is desired that Jill pushes the car so that the speed is constant

take as positive the direction of Jack's thrust

             F_jack - F_jill = 0

              F_jill = F_jack

therefore the push of the two must be equal and Jill's push must have the opposite direction to Jack's push.

The correct answer is NONE the two forces must be equal and of opposite direction, the closest answer is D

Answer:

the answer is B. it's too easy

Answer:

F = 0.0112 N

Explanation:

Given that,

Masses, [tex]m_1=m_2=6500\ kg[/tex]

The distance between masses, d = 0.5 m

We need to find the gravitational force between two large trucks. The formula for the gravitational forces is given by :

[tex]F=G\dfrac{m^2}{r^2}\\\\F=6.67\times 10^{-11}\times \dfrac{6500^2}{(0.5)^2}\\\\F=0.0112\ N[/tex]

So, the required force between masses is equal to 0.0112 N.

Answer:

x = 0.78 m = 78 cm

Explanation:

Applying the law of conservation of energy to the spring-mass system, we can write the following equation:

[tex]Kinetic\ Energy\ at\ Mean\ Position= Potential\ Energy\ at\ extreme\ position\\\frac{1}{2}mv^2 = \frac{1}{2}kx^2\\\\x^2 = \frac{mv^2}{k}\\\\x = \sqrt{\frac{mv^2}{k} }[/tex]

where,

x = maximum displacement = ?

m = mass = 3.6 kg

v = speed at mean position = 5.2 m/s

k = spring constant = 160 N/m

Therefore,

[tex]x = \sqrt{\frac{(3.6\ kg)(5.2\ m/s)^2}{160\ N/m} }\\\\[/tex]

x = 0.78 m = 78 cm

Answer:

300 m.

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 15 m/s

Final velocity (v) = 25 m/s

Time (t) = 15 secs

Distance (s) =?

The distance travelled by the motorbike can be obtained as follow:

s = (u + v)t / 2

s = (15 + 25) × 15 / 2

s = 40 × 15 / 2

s = 600 / 2

s = 300 m

Thus, the distance travelled by the motorbike is 300 m.

The interference is a  type of wave interaction shown in the photo. Option A is correct.

The result of two or more wave trains flowing in opposite directions on a crossing or coinciding pathways. This phenomenon is known as the interference of waves.

The effect is the sum of the individual wave amplitudes at each site where more than one wave is present.

When two wave pulses are traveling along a string toward each other. They meet and the phenomenon is occur known as interference.

Answer:

1 ohm

Explanation:

since there are two identical resistors, one resistor will be

R = [tex]\frac{4}{2}[/tex] =2ohm [ proven as in series [tex]R_{e} = 2 + 2 = 4ohm[/tex] ]

to calculate the equivalent resistance when in parallel:

[tex]\frac{1}{R_{e} } = \frac{1}{R_{1} } + \frac{1}{R_{2}}[/tex]

so,

[tex]\frac{1}{R_{e} } = \frac{1}{2} + \frac{1}{2}[/tex]

[tex]R_{e} = 1ohm[/tex]

Two identical resistors connected in series have an equivalent resistance of 4 ohms. The same two resistors, when connected in parallel, have an equivalent resistance of 1 ohm.

In a parallel circuit, voltage is thee same across each component in the circuit. The sum of the currents through each path is equal to the current from the source. However, the resistance cannot be added directly. It is calculated as:

1/Rt = 1/R1 + 1/R2 + 1/R3 1/Rt = 1/6.8 + 1/9.0 + 1/15

Rt = 3.08 ohms.

When resistors are connected in parallel, the equivalent resistance R will be less than the least resistance.

1/R = 1/R1 + 1/R2 + 1/R3 + 1/R4 + 1/R5

Since the 5 resistors are 10 ohms each, substitute them in to the formula

1/R = 1/10 + 1/10 +1/10 + 1/10 + 1/10

The LCM = 10

1/R = 5/10

Reciprocate both sides

R = 10/5 = 2 ohms

Therefore, Two identical resistors connected in series have an equivalent resistance of 4 ohms. The same two resistors, when connected in parallel, have an equivalent resistance of 1 ohm.

Answer:

A. respiration.

Explanation:

Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.

Additionally, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.

Basically, oxygen goes into the body of a living organism such as plants, humans and animals when they breathe while glucose is absorbed by the body when they eat.

Hence, the conversion of sugar to energy in the presence of oxygen is respiration.

Answer: 0.25 m/s

Explanation:  Speed = wavelengt · frequency

Explanation:

Mitochondria are essential parts of many eukaryotes, but they are useless without oxygen. Therefore, chloroplasts are extremely important. They produce breathable air for life. Root hairs are seen to not have chloroplasts as their job is to collect water and nutrients.

Answer:

some symptoms can be lack of energy, and dizziness.

Explanation:

The carbon cycle refers to the processes by which carbon in the biosphere is recycled. Photosynthesis sucks carbon dioxide out of the atmosphere, while cellular respiration releases it into the environment. Photosynthesis is the process by which solar energy reaches a plant and is converted into glucose.

How photosynthesis and cellular respiration are similar:

Photosynthesis is a method by which plants and other organisms transform light energy into chemical energy, which is then released to fuel the organism's metabolic activities through cellular respiration.

Answer:

F = 4117.64

Explanation:

First, we will calculate the acceleration of the hand, by using the third equation of motion:

[tex]2as = v_f^2 - v_i^2\\[/tex]

where,

a = acceleration = ?

s = distance covered = compression = 8.5 cm = 0.085 m

vf = final speed = 0 m/s

vi = iniial speed = 10 m/s

Therefore,

[tex]2a(0.085\ m) = (0\ m/s)^2-(10\ m/s)^2\\a = - 588.23\ m/s^2[/tex]

negative sign hows deceleration.

Now, we will calculate the force exerted by the hand:

[tex]F = ma = (7\ kg)(588.23\ m/s^2)\\[/tex]

F = 4117.64 N

The smaller the mass of an object, the smaller its inertia, because the inertia of any object is directly proportional to the mass of the object

The ability of an object to resist changes in motion is known as inertia. The amount of inertia is directly related to an object's mass; in fact, as we frequently observe, the heavier an object is, the harder it is to change its direction of motion.

A straightforward illustration: While it is relatively simple to stop a tennis ball that has been thrown in our direction, we are aware that it is more difficult to stop a large truck that is moving in the same direction at the same speed. This is because the truck has a much higher mass than the tennis ball and a higher moment of inertia. As a result, inertia rises as mass does.

Since the inertia of any object is directly proportional to its mass, the smaller its mass, the less inertia it will have.

n = ?

so by ohms law , V = I X R

we know that I = Q / T here t is 1 sec

Q = I X T = 0.5 X 1 = 0.5 C
