Answer:

Sí se puede aplicar el Principio de Conservación de la Energía Mécanica siempre y cuando se considere los efectos de pérdida de energía a causa del rozamiento, de lo contrario, no se cumpliría el requisito de conservación derivado del citado principio de conservación.  

Explanation:

Consideremos que el cuerpo representa nuestro sistema de estudio, el cual se desplaza por una carretera y experimenta rozamiento, significando cambios en la energía cinética y potencial gravitacional. La presencia de rozamiento indica una disipación de la energía del cuerpo, cuya energía mecánica total disminuye, significando un sistema no conservativo.

The radioactive decay is shown in the image attached to this answer

Answer:

Alpha

Explanation:

An alpha decay is said to have occurred when the mass number of the daughter nucleus decreases by four units and the atomic number of the daughter nucleus decreases by two units.

If we look at the equation from left to right, we will notice that the mass number of the daughter nucleus decreased by four units and the atomic of the daughter nucleus number by two units compared to that of the parent nucleus leading to the emission of an alpha particle.

Answer: ITS T

Explanation:

In a motor, electrical current enters through the brushes. TRUE.

Answer:

Explanation:

PE = m * g * h

m = 200 kg

h = 1000 m

g = 9.81

PE = 200 * 9.81 * 1000

PE = 1962000 Joules

Answer:

E = 950 J

Explanation:

The total amount of energy that can be transformed into gravitational energy will be equal to the kinetic energy of the ball at initial state:

[tex]E = K.E = \frac{1}{2} mv^2[/tex]

where, E = Energy = ?

m = mass of the ball = 19 kg

v = initial speed of the ball = 10 m/s

Therefore,

[tex]E = \frac{1}{2} (19\ kg)(10\ m/s)^2[/tex]

E = 950 J

Machine 2’s mechanical advantage is greater, which means that this machine can do more work with less force than Machine 1.

The term mechanical advantage is the ratio of the radius of wheel to the radius of the axle for a wheel and axle system.

The true statement about the two machines that were compared; 1 and 2 is that, machine 2’s mechanical advantage is greater, which means that this machine can do more work with less force than Machine 1.

Answer: an object in motion stays in motion unless acted upon by an unbalanced force

Explanation: this is Newton’s first law of motion, which states that an object, whether in a moving or resting state, will continue to stay in that state unless there is an unbalanced force that changes that state. For a moving object, an example would be friction worth the ground. For a resting object, an example would be the force of a push.

Globular star clusters form from tightly packed groups and/or older ancient stars.

Globular star clusters can be defined as ancient stars packed in a spherical and/or symmetrical shape.

Globular star clusters represent the most common types of groups (i.e., clusters) of ancient stars.

These groups of stars (globular) are characterized to be densest in the center of the cluster.

In conclusion, globular star clusters form from tightly packed groups and/or older ancient stars.

Answer:

Recessive alleles only show their effect if the individual has two copies of the allele.  

Explanation:

Dominant and Recessive Alleles If your allele pair is FF or Ff, you will have freckles. The only way you can escape a freckled face is to inherit the recessive gene from each parent, giving you the ff allele pair. In general, recessive alleles show up in your phenotype only if you have two of them.

Explanation:

Given:

m1 = 0.55 kg

m2 = 0.45 kg

vi1 = +5.8 m/a

vi2 = -3.9 m/a

Solve for V

m1vi1 + m2vi2 = (m1 + m2)V

(0.55 kg)(+5.8 m/s) + (0.45 kg)(-3.9 m/s) = (0.55 + 0.45)V

V = +1.46 m/a

This means that the combined mass after the collision is moving to the right at 1.46 m/s

Answer:

A force pump can be used to raise water by a height of more than 10m, the maximum height allowed by atmospheric pressure using a common lift pump.

In a force pump, the upstroke of the piston draws water, through an inlet valve, into the cylinder. On the downstroke, the water is discharged, through an outlet valve, into the outlet pipe.

Answer:

Amount of work done by Joanne = 80 joule

Explanation:

Given:

Displacement of ball = 2 meters

Force applied = 40 newtons

Find:

Amount of work done by Joanne

Computation;

Work done = Force applied x Displacement

Amount of work done by Joanne = Force applied x Displacement of ball

Amount of work done by Joanne = 40 x 2

Amount of work done by Joanne = 80 joule
