Explanation:

The momentum of an object can be found by using the formula

momentum = mass × velocity

From the question

mass = 1000 kg

velocity = 5 m/s

We have

momentum = 1000 × 5 = 5000

Explanation:

The useful energy generated by the machine having an efficiency of 15% and an energy input of 300 J is 45 J

Efficiency = 15% = 0.15

Work input = 300 J

The useful energy generated (i.e work output) by the machine can be obtained as follow:

[tex]Efficiency = \frac{workout}{workin} * 100\\\\0.15 = \frac{Workout}{300}[/tex]

Cross multiply

Work output = 0.15 × 300

Therefore, the useful energy generated by the machine is 45 J

first resolve the initial velocity of the ball into two components

1)one parallel to ground(u)

2)another perpendicular to ground(v)

call the initial velocity=p=25.4 m/s at 58.0° deg to ground

so the horizontal component of velocity=25.4cos58=13.46 m/s

so the vertical component of velocity=25.4sin58=21.54 m/s

we have nothing to do with the horizontal component of velocity as it plays no part in the hang time

only vertical component of velocity determines the hang time

hang time=2*(vertical component of velocity)/(acceleration due to gravity)

==>hang time=2*21.54/9.8=4.39 s

==>hang time =4.39 s

The position of an ant and a spider in a room are A(2,3,5) and B(6,0,8)  the distance between ant and spider is 5.83 m.

The distance formula states that the distance between two points in xyz-space is the square root of the sum of the squares of the differences between corresponding coordinates A( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] , [tex]z_{1}[/tex] ) and B( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] ,[tex]z_{2}[/tex]),

AB² = ([tex]x_{2}[/tex] - [tex]x_{1}[/tex])² + ([tex]y_{2}[/tex] - [tex]y_{1}[/tex])² + ( [tex]z_{2}[/tex]  - [tex]z_{1}[/tex] )²

In reality, the Pythagorean Theorem is nothing more than the distance formula. Draw a right triangle using the segment AB as its hypotenuse in order to get the distance AB between points  A( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )  and B( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] ).

Given that in the question two points are A(2,3,5) and B(6,0,8), so the distance between them is

AB² = ([tex]x_{2}[/tex] - [tex]x_{1}[/tex])² + ([tex]y_{2}[/tex] - [tex]y_{1}[/tex])² + ( [tex]z_{2}[/tex]  - [tex]z_{1}[/tex] )²

AB² = 4² + 3² + 3²

AB² = 34

Explanation:

The human brain has the capacity to generate new neurons throughout the lifespan (option b).

The correct statement regarding the development and growth of new neurons in the human brain is option A. The human brain has the capacity to generate new neurons throughout the lifespan.

1. Neurogenesis, the process of generating new neurons, was once believed to be limited to early brain development and not to occur in adulthood. However, recent research has challenged this notion.

2. Studies conducted on adult brains have provided evidence of neurogenesis occurring in specific regions of the brain, such as the hippocampus, which is involved in learning and memory.

3. Neurogenesis in the adult brain involves the generation of new neurons from neural stem cells. These stem cells have the ability to differentiate into mature neurons and integrate into existing neural circuits.

4. The process of neurogenesis is influenced by various factors, including environmental enrichment, physical exercise, and certain medications.

5. It is important to note that while neurogenesis occurs in the adult human brain, the rate of neurogenesis is relatively low compared to early brain development.

6. In contrast to option B, there is evidence to support the idea that neurogenesis continues to occur in the human brain after birth and throughout life.

7. Option C is incorrect because while glial cells, a type of support cell in the brain, can reproduce and grow in number throughout adulthood, neurons also have the capacity to generate new neurons.

8. Option D is incorrect as several animal species, including primates, birds, and rodents, have been found to experience neurogenesis in various stages of their lives.

In conclusion, option A is the true statement regarding the development and growth of new neurons in the human brain, as neurogenesis can occur throughout the lifespan.

Answer:

I think A. I had a similar question

Explanation:

24.8 m/s

Explanation:

You don't have to solve for time first. You can use the equation below to solve for the velocity before impact:

[tex]v_y^2 = v_{0y}^2 + 2a_yy[/tex]

We know that [tex]v_{0y} = 0[/tex] so the equation above becomes

[tex]v_y^2 = 2a_yy \Rightarrow v_y = \sqrt{-2a_yy}[/tex]

Plugging in the numbers, we get

[tex]v_y = \sqrt{-2(-9.8\:\text{m/s}^2)(31.3\:\text{m})}[/tex]

[tex]\:\:\:\:\:=24.8\:\text{m/s}[/tex]

METHOD 2:

If you insist on using that equation for d, we can do that too. So solving for t from the equation for d. we get

[tex]t = \sqrt{\dfrac{2d}{g}} = \sqrt{\dfrac{2(31.3\:\text{m})}{9.8\:\text{m/s}^2}}[/tex]

[tex]\:\:\:\:= 2.53\:\text{s}[/tex]

So using the equation [tex]v_y = gt,[/tex] we get

[tex]v_y = (9.8\:\text{m/s}^2)(2.53\:\text{s}) = 24.8\:\text{m/s}[/tex]

So you get the same result regardless of the method you use.

Answer:

Explanation:

Assuming we are looking parallel to a horizontal pivot pin with positive UP to the top of the picture, and the 20 N force acts perpendicular to the rod.

Sum moments about C to zero assume CW is the positive moment.

The rod mass causes no moment because there is no moment arm about C.

Fsin50[1.0} - 20[0.5] = 0

F = 10/sin50

F = 13 N

Summing vertical forces to zero With R being the pin reaction at C

Ry - F - 20sin50 - mg = 0

Ry = 13 + 20sin50 + 10(9.8)

Ry = 126.32 N

Summing horizontal forces to zero assuming a right directed force is positive.

Rx + 20cos50 = 0

Rx = -12.855...

R = √(-12.855² + 126.32²) = 126.972

R = 127 N

θ =arctan(126.32/-12.855) = 95.8107... = 5.8° CCW from UP

a) Las balas de cañon disparadas desde el puerto deben tener una ángulo de 27.39° para que puedan impactar al barco, con una velocidad inicial de 82 m/s.

b) El tiempo de vuelo de las balas de cañon para alcanzar al barco que está a 560 m de distancia es de 7.69 s.

c) Sabiendo que el ángulo calculado en el inciso a) es para una distancia de 560 m, el barco debe estar a una distancia mayor para que las balas no lo alcancen.

a)

Podemos usar las ecuaciones de tiro parabólico para encontrar el ángulo que permita derribar al barco invasor.

[tex]x=\frac{v_{i}^{2}sin(2\alpha)}{g}[/tex] (1)

Donde:

Lo que debemos hacer es depejar α de la ecuación 1

[tex]sin(2\alpha)=\frac{xg}{v_{i}^{2}}[/tex]

[tex]sin(2\alpha)=\frac{560*9.81}{82^{2}}[/tex]

[tex]sin(2\alpha)=0.82[/tex]

[tex]\alpha=\frac{sin^{-1}(0.82)}{2}[/tex]

[tex]\alpha=27.39^{\circ}[/tex]

Por lo tanto, el ángulo para que el cañón impacte en el barco es de 27.39 °.

b)

Sabemos que la componente de la velocidad en el eje x es constante, así que podemo usar la siguiente ecuación.

[tex]v_{x}=\frac{x}{t}[/tex]

La componente x de la velocidad es V(x) = V(i)cos(α) y sabiendo la distancia total de 560 m, el tiempo será:

[tex]v_{i}cos(\alpha)=\frac{x}{t}[/tex]

[tex]t=\frac{x}{v_{i}cos(\alpha)}[/tex]

[tex]t=\frac{560}{82cos(27.39)}[/tex]

[tex]t=7.69\: s[/tex]

El tiempo total de vuelo de las balas de cañon es de 7.69 s.

c)

Sabemos que el ángulo calculado en el inciso a) es de 27.39 °, y ese valor fue calcualdo para una distancia de 560 m, por lo tanto el barco debe estar a una distancia mayor que esa para que las balas no lo alcancen.
