Answers

Answer:

[tex]0.00074m[/tex] [tex]=[/tex] [tex]7.4*10^{-4}m[/tex]

Explanation:

Given

[tex]0.00074m[/tex]

Required

Express as scientific notation

The scientific notation of a number is: [tex]a * 10^{b}[/tex]

Where [tex]1 \le a \le 9[/tex]

This implies that:

[tex]0.00074m = 7.4 * 10^b[/tex]

Next, is to determine the value of b.

Count the number of point to move from the current point location to 7.4.

If the point moves backward, b will be negative, else b will be positive.

So:

[tex]0.00074m[/tex]      [tex]b=-4[/tex]

Hence:

[tex]0.00074m[/tex] [tex]=[/tex] [tex]7.4*10^{-4}m[/tex]

Astronomers were at first surprised to find complicated molecules in the interstellar medium. They thought ultra-violet light from stars would break apart such molecules. What protects the molecules we observe from being broken apart?A. such molecules form in cells, and there is a protective membrane around each cellB. such molecules always form inside stars; the stars outer layers protect themC. such molecules form in clouds that contain significant amounts of dust, and the dust in the cloud protects them from ultra-violet raysD. such molecules form only in the regions that are already millions of degrees hot and thus can’t be affected by ultra-violet raysE. you can’t fool me; the seeming discovery of complex molecules out there was a mistake, and astronomers now realize there are no molecules out there.

Answers

Answer:

The objects that protects the molecules observed from being broken apart is option C;

Such molecules form in clouds that contain significant amount of dust, and the dust in the cloud protects them from ultra-violet rays

Explanation:

The existence of high energy cosmic and ultraviolet radiation is capable of breaking molecules present within translucent clouds in the interstellar medium.

However, when the light is passed through translucent clouds that are several light years thick or through non-transparent clouds interactions with the gases and dusts result in changes in the starlight that reaches a certain distance such as Earth

Therefore, the formation and presence of such molecules in clouds that are made up of dust serves to protect them from being broken by the high energy ultraviolet rays from the stars.

Calculate the force of an object shot in the air with a mass of 2 kg and an acceleration of 9.81 m/s2.

Answers

Answer:

Force = 19.62 Newton

Explanation:

Given the following data;

Mass = 2kg

Acceleration = 9.81 m/s²

To find the force;

Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.

Mathematically, it is given by the formula;

Force = mass * acceleration

Substituting into the formula, we have;

Force = 2 * 9.81

Force = 19.62 Newton

Your little cousin loves ice cream bars. You buy him one and he starts to lick it. As you sit down on a park bench, he drops
the bar on the seat of the bench. You pick up the bar to throw it away, but he starts to cry, so you shrug and give it back to
him. Will he definitely get sick?

Answers

Answer:

nop

Explanation:

It is not certain whether the child will get sick from eating the ice cream bar that was dropped on the bench.

What is contamination?

Contamination refers to the presence or introduction of harmful substances or organisms into a material, environment, or food source.

There is a possibility that the ice cream bar could have picked up bacteria or other contaminants from the bench that could make the child sick. However, the risk of illness depends on a number of factors, including the cleanliness of the bench, the length of time the ice cream was in contact with the bench, and the overall health of the child's immune system.

To reduce the risk of illness, it is important to wash hands and surfaces frequently, especially when handling food. If possible, it is best to discard food that has come into contact with potentially contaminated surfaces to prevent the spread of illness. However, if the child has already eaten the ice cream bar and does become sick, it is important to monitor their symptoms and seek medical attention if necessary.

A man's higher initial acceleration means that a man can outrun a horse over a very short race. A simple - but plausible - model for a sprint by a man and a horse uses the following assumptions: The man accelerates at 6.0 m/s2for 1.8 s and then runs at a constant speed. A horse accelerates at a more modest 5.0 m/s2 but continues accelerating for 4.8 s and then continues at a constant speed. A man and a horse are competing in a 200 m race. The man is given a 100 m head start, so he begins 100 mfrom the finish line.

How much time does it take the man to finish the race? The horse? Who wins?

Answers

Answer:

 t_man = 10.16 s,   t_horse = 10.73 s,  the winner is the man

Explanation:

To solve this problem we are going to find the time of each one separately.

Man we look for distance and time during acceleration

         x₁ =  v₀ t₁ + ½ a₁ t₁²

as it comes out of rest its initial velocity is zero

        x₁ = ½ a₁ t₁²

        x₁ = ½ 6.0 1.8²

        x₁ = 9.72 m

at this point its speed is

        v₁ = v₀ + a t

        v₁ = 0 + 6  1.8

        v₁ = 10.8 m / s

From here on it continues at constant speed, the distance that the man needs to travel from the point where the man leaves at 100m is

        x₂ = 100 - x₁

        x₂ = 100- 9.72

        x₂ = 90.28 m

the time for this part is

        v₁ = x₂ / t₂

         t₂ = x₂ / v₂

         t₂ = 90.28 / 10.8

         t₂ = 8.36 s

the total time for the man is

        t_man = t₁ + t₂

        t _man = 1.8 + 8.36

        t_man = 10.16 s

We repeat the calculation for the horse

distance traveled during the acceleration period

         x₃ = v₀ t + ½ a₂ t₃²

as part of rest its initial velocity is zero

        x₃ = ½  a₂ t₃²

        x₃ = ½  5.0  4.8²

        x₃ = 57.6 m

the velocity at this point is

         v₃ = v₀ + a₂ t₃

         v₃ = 0 + 5  4.8

         v₃ = 24 m / s

the rest of the route is at constant speed, the remaining distance

         x₄ = 200 - x₃

         x₄ = 200 - 57.6

         x₄ = 142.4 m

the time to go through it is

         t₄ = x₄ / v₃

         t₄ = 142.4 / 24

         t₄ = 5.93 s

the total time for the horse is

         t_horse = t₃ + t₄

         t_horse = 4.8 + 5.93

         t_horse = 10.73 s

when we compare the times we see that the man arrives a little before the horse, the winner is the man

Un ciclista recorre 10 km en 2 h.Calcula su velocidad media en km/h.¿cuantos metros recorre cada segundo

Answers

Answer:

La velocidad media es 5 [tex]\frac{km}{h}[/tex], que equivale a 1.389 [tex]\frac{m}{s}[/tex]

Explanation:

La velocidad es una magnitud física que expresa la relación entre el espacio recorrido por un objeto y el tiempo empleado para ello.

La velocidad media relaciona el cambio de la posición con el tiempo empleado en efectuar dicho cambio. Por lo que se calcula como la distancia recorrida por un objeto dividido por el tiempo transcurrido:

[tex]velocidad=\frac{distancia}{tiempo}[/tex]

En este caso:

distancia= 10 km= 10,000 m (siendo 1 km= 1,000 m)tiempo= 2 h= 7,200 s (siendo 1 h= 3,600 s)

Entonces, reemplazando en la definición de velocidad media:

[tex]velocidad=\frac{10 km}{2 h}= \frac{10,000 m}{7,200 s}[/tex]

Resolviendo se obtiene:

[tex]velocidad=5 \frac{km}{h}= 1.389\frac{m}{s}[/tex]

La velocidad media es 5 [tex]\frac{km}{h}[/tex], que equivale a 1.389 [tex]\frac{m}{s}[/tex]

The spring and object are compressed by 0.065 m, released from rest, and subsequently oscillate back and forth with an angular frequency of 11.3 rad/s. What is the speed of the object at the instant when the spring is stretched by 0.048 m relative to its unstrained length

Answers

Answer:

Explanation:

Given that:

angular frequency = 11.3 rad/s

Spring constant (k) = [tex]= \omega^2 \times m[/tex]

k = (11.3)² m

k = 127.7 m

where;

[tex]x_1[/tex] = 0.065 m

[tex]x_2[/tex]  = 0.048 m

According to the conservation of energies;

[tex]E_1=E_2[/tex]

[tex]\Big(\dfrac{1}{2} \Big) kx_1^2 =\Big(\dfrac{1}{2} \Big) mv_2^2 + \Big(\dfrac{1}{2} \Big) kx_2^2[/tex]

[tex]kx_1^2 = mv_2^2 + kx_2^2[/tex]

[tex](127.7 \ m) \times 0.065^2 = v_2^2 + (127.7 \ m) \times 0.048^2[/tex]

[tex]0.5395325 = v_2^2 +0.2942208 \\ \\ 0.5395325 - 0.2942208 = v_2^2 \\ \\ v_2^2 = 0.2453117 \\ \\ v_2 = \sqrt{0.2453117} \\ \\ \mathbf{ v_2 \simeq0.50 \ m/s}[/tex]

(2) Nyad, a veteran of several marathons swims, wants to set a new world record for the longest open-water swim. (3) In 1974 she swam across Lake Ontario from north to southa difficult crossing because of the swift current of the Niagara river. (4) A year later she completed a swim of more than 25 miles around New York Citys Manhattan Island, she had battled dangerous currents for nearly eight hours. (5) The swim from the Bahamas to Florida, however, would be far more treacherous than anything she had previously attempted. (6) It would require exceptional physical and mental strength.(7) Nyad, like other long-distance swimmers, knew that every marathon swim is a grueling physical experence. (8) In earlier marathons she had become delirious from the fatigue of continuous stroking, kicking, and breathing. (9) She also knew that her senses would become impaired. (10) Her dark goggles would fog over, making it impossible for her to see. (11) Even though her coach and crew were in a support boat only twenty feet away, the tight rubber swim cap that covered her ears would prevent her from hearing thecoachs whistle. (12) The salt water would even affect her senses of taste, touch, and smell.(13) In addition to extreme physical exhaustion, Nyad was aware of the many dangers she would face in the water. (14) During earlier marathons schools of jellyfish had repeatedly stung her. (15) On Nyads Bahamas-to-Florida swim, a shark appeared.(16) Nyads crew was prepared with an electronic shark shield. (17) Crew members sent out a wave of electricity that did not harm Nyad but affected the shark and cause them to turn away. (18) Electricity can be used to repel many other kinds of animals.
