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.

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]

A .001 kg bead slides without friction around a loop-the-loop. The bead is released from a height of 20.6 m from the bottom of the loop-the-loop which has a radius 7 m. The acceleration of gravity is 9.8 m/s [photo] What is its speed at point A ? Answer in units of m/s. Your answer must be within ± 5.0%

Answers

Answer:

11.37 m/s

Explanation:

We are given;

Mass; m = 0.001 kg

Initial velocity; v1 = 0 m/s (since it was released from rest)

Initial height; h1 = 20.6m

From the attached image of the bead in the loop, we can see that height at A; h2 = twice the radius = 2R = 2 × 7 = 14 m

g = 9.8

To solve for the speed at point, we will use formula for conservation of energy. Thus;

½m(v1)² + mgh1 = ½m(v2)² + mgh2

Divide through by m to get;

½(v1)² + gh1 = ½(v2)² + gh2

Plugging in the relevant values;

½(0²) + (9.8 × 20.6) = ½(v2)² + (9.8 × 14)

Rearranging, we have;

½(v2)² = ½(0²) + (9.8 × 20.6) - (9.8 × 14)

Simplifying, we have;

½(v2)² = 64.68

Multiply both sides by 2 to get;

(v2)² = 2 × 64.68

(v2)² = 129.36

v2 = √129.36

v2 = 11.37 m/s

A bag of marbles is hanging motionless on a spring scale. What prevents the bag from falling?​

Answers

Answer:

The vector sum of all forces acting on it is zero, its at equilibrium.

Explanation:

The bag of marbles hanging on a spring scale applies its weight downwards, which was counterbalanced by the reaction from the spring scale (obeying the Newton's third law of motion). And since no external forces are applied to the system, thus the equilibrium of the system.

If the weight of the bag is greater than the reaction from the spring scale, the scale breaks and the system would not be balanced.

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

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.

Cold water flows to the solar panels at 15°C. During the day, the panels supply 3.8 kg of hot water
at 65°C every hour.
(a) Calculate the average energy that the solar panels deliver to the water in one hour.
Specific heat capacity of water = 4200 J/(kg°C). ​

Answers

Answer:

The average energy that the solar panel delivers to the water in one hour is 798,000 Joules

Explanation:

The given parameters are;

The temperature of the water that flows to the solar panels, T₁ = 15°

The mass of the hot water the panel supplies during the day, m = 3.5 kg

The temperature of the hot water supplied by the panel, T₂ = 65 °C

The heat capacity of the water, c = 4,200 J/(kg·°C)

The heat delivered to the solar panels in one hour, ΔQ, is given by the following formula

ΔQ = m·c·ΔT

m = 3.8 kg, c = 4,200 J/(kg·°C), and ΔT = T₂ - T₁ = 65 °C - 15 °C = 50 °C

∴ ΔQ = 3.8 kg × 4,200 J/(kg·°C) × 50°C = 798,000 joules

∴ΔQ = 798,000 joules

The average energy that the solar panel delivers to the water in one hour, ΔQ = 798,000 joules.

A 10 kg firework is shot in the air at 75 m/s. What is the momentum of the firework?

Answers

Answer:

Momentum = 750 Kgm/s

Explanation:

Given the following data;

Mass = 10 kg

Velocity = 75 m/s

To find the momentum;

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]

Substituting into the formula, we have;

Momentum = 10 * 75

Momentum = 750 Kgm/s

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:

Answer:

Explanation:

Given that:

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]
