Kyra and Pari are timing how long it takes for 1 g of sugar to dissolve in hot water. Kyra records a time of 24.3 seconds. Pari records a time of 24 seconds. Whose reading is more precise? Why?

Answers

Answer 1
Answer:we can say that:-A reading with more no of significant figures is considered to be more precise.Kyra recorded a reading of 24.3 sec. Since all non 0 digits are considered to be significant this reading has 3 significant figures.Pari recorded a reading of 24 sec. Since all non 0 digits are considered to be significant this reading has 3 significant figures.hence we can say that kyra's reading has more significant figures nd so it is more precise.

Answer:

Sample Response: In the lab, I discovered the air pressure, air temperature, and relative humidity conditions that create snow, rain, thunderstorms, fog, and clear skies. I learned that low-pressure areas usually experience snowy, rainy, and stormy weather, and that high-pressure areas usually experience either foggy or sunny weather. Knowing how these atmospheric conditions influence weather help weather forecasters predict weather patterns through maps and other information.

In which circuit will the bulb or bulbs glow brightest?
a-A simple circuit with one bulb and one battery
b-A simple circuit with one bulb and two batteries
C-A simple circuit with two bulbs and one battery

Answers

Answer:

B - a simple circuit with one bulb and two batteries.

The circuit that would glow brightest is b - A simple circuit with one bulb and two batteries

Electric circuit

This is the path for transmitting current. It usually consists of an electrical energy source and an electrical load.

In any circuit, the electrical power available is determined by the number of batteries available (energy source) and thus the current.

Ohm's law

Since we know according to Ohm's law V = iR where

V = voltage, i = current and R = load.

So, making i subject of the formula, we have i = V/R .

So, i ∝ 1/R this shows that the current is inversely proportional to the load.

Circuit that would glow brightest

a simple circuit with more current and less load would glow brightest. So, having a simple circuit with two batteries increases the current in the circuit and having only one bulb means that there is less load in the circuit. Thus, the circuit with one bulb and two batteries will glow brightest.

So, the circuit that would glow brightest is b - A simple circuit with one bulb and two batteries

Un automóvil viaja a la velocidad de 10 m/s. Se acelera Durante 12s y aumenta su velocidad hasta 70 m/s ¿Que aceleración experimenta el automóvil?

Answers

Answer:

Aceleracion = 5 m/s²

Explanation:

Dados los siguientes datos;

Velocidad inicial = 10 m/s

Velocidad final = 70 m/s

Tiempo, t = 12 segundos

Para encontrar la aceleración;

Aceleración se puede definir como la tasa de cambio de la velocidad de un objeto con respecto al tiempo.

Esto simplemente significa que la aceleración viene dada por la resta de la velocidad inicial de la velocidad final a lo largo del tiempo.

Por lo tanto, si restamos la velocidad inicial de la velocidad final y la dividimos por el tiempo, podemos calcular la aceleración de un objeto. Matemáticamente, la aceleración viene dada por la fórmula;

[tex] Aceleracion = \frac{final \; velocidad - inicial \; velocidad}{tiempo}[/tex]

Sustituyendo en la fórmula, tenemos;

[tex] Aceleracion = \frac{70 - 10}{12}[/tex]

[tex] Aceleracion = \frac{60}{12}[/tex]

Aceleracion = 5 m/s²

Answers

Answer:

[tex]2380\ \text{m}[/tex]

[tex]7.93\times 10^{-6}\ \text{s}[/tex]

Explanation:

t = Temps mis par la foudre pour parcourir la distance = 7 secondes

v = Vitesse du son dans l'air = 340 m / s

La distance est donnée par

[tex]s=vt\\\Rightarrow s=340\times 7\\\Rightarrow s=2380\ \text{m}[/tex]

L'éclair est tombé à une distance de [tex]2380\ \text{m}[/tex]

c = Speed of light = [tex]3\times 10^8\ \text{m/s}[/tex]

Le temps est donné par

[tex]t=\dfrac{s}{c}\\\Rightarrow t=\dfrac{2380}{3\times 10^8}\\\Rightarrow t=7.93\times 10^{-6}\ \text{s}[/tex]

Le temps mis par la lumière pour parcourir la distance est de [tex]7.93\times 10^{-6}\ \text{s}[/tex].

Weather such as raining has water molecules/droplets thats been evaporated from the ocean and other areas that's wet, the water will connect and soon the mass of the water will become heavy causing rainfall. Snow in another case has been caused to freeze from low climates creating a snow flake to fall from the sky. Hail is another case however the water that becomes ice is far more larger.

The variety of activities that take place daily in our atmosphere makes up for the weather.

What is the weather like?

The weather varies across the globe and changes over a few minutes, hours, days, and weeks. The troposphere, the region of Earth's atmosphere closest to the surface, is where most weather occurs.

Changes in air pressure determine the weather that occurs in a given place. The weight of the enormous quantities of air molecules that make up the atmosphere is what causes air pressure.

Usually, clear, blue skies are seen when air pressure is high. The high pressure prevents clouds from developing by causing air to flow down and fan out as it gets close to the ground.

Low air pressure causes air to move together before converging upward, where it rises, cools, and forms clouds.

a)  F = 1.26 10⁵ N,  b)  F = 2.255 10³ N, c)   F_ {soil} = 3078 N

Explanation:

For this exercise we will use the relationship between momentum and moment

          I = Δp

          F t = p_f -p₀

a) with stiff legs, final speed is zero, initial velocity is down

         Ft = 0-p₀

         F =  m v / t

let's calculate

         F = 84.0 6.82 / 4.56 10⁻³

         F = 1.26 10⁵ N

         

b) bending the legs

         

let's calculate

         F = 84.0 6.82 / 0.254

         F = 2.255 10³ N

     

c) It is requested to calculate the force of the ground on the man

            ∑ F = F_soil -W

           F_soil = F + W

           F_ {soil} = 2.255 103 + 84 9.8

           F_ {soil} = 3078 N

Focus on the blue and red arrows that represent the vertical and horizontal components of the golf ball’s velocity. As the ball flies through the air, what do you notice about the blue (vertical) arrow?

Answers

Answer:

v_y = v_{oy} - g t

where the upward direction is positive, so the arrow represents this speed (blue) must decrease, reach zero and grow in a negative direction as time progresses

Explanation:

In this exercise you are asked to observe the change in velocity in a projectile launch.

If we assume that the friction force is small, the velocity in the x-axis must be constant

         vₓ = v₀ₓ

Therefore, the arrow (red) that represents this movement must not change in magnitude.

In the direction of the y axis, the acceleration of gravity is acting, so the magnitude of the velocity in this axis changes

         v_y = v_{oy} - g t

where the upward direction is positive, so the arrow represents this speed (blue) must decrease, reach zero and grow in a negative direction as time progresses

5. A cable is attached 32.0 m from the base of a flagpole that is about to
be raised. The raising of the pole is temporarily halted when the pole is
at an angle of 60.0° with respect to the ground. If the cable exerts a ver-
tical force of 1.233 x 104 N downward and a horizontal force of 1.233 x
104 N to the left, what is the length of the flagpole?

Answers

Answer:

The length of the flagpole is approximately 87.43 m

Explanation:

The given parameters of the cable attached to the flagpole are;

The point along the flagpole at which the cable is attached = 32.0 m

The angle with respect to the ground at which the raising of the flagpole is halted = 60.0°

The downward force exerted by the cable, [tex]F_v[/tex] = 1.233 × 10⁴ N

The force exerted by the cable to the left = 1.233 × 10⁴ N

Let 'W' represent the weight of the flagpole, at equilibrium, we have;

The sum of vertical forces = 0

Therefore;

[tex]F_v[/tex] + W - R = 0

W - R = -1.233 × 10⁴ N

Taking moment about the support at the base of the pole, we get;

1.233 × 10⁴ × d × cos(60.0°) - 1.233 × 10⁴ ×d× sin(60.0°) + W × d/2 ×cos(60.0°) = 0

∴ W × d/2 ×cos(60.0°) ≈  4513.093·d  

W = 2 × 4513.093/(cos(60.0°)) ≈ 18,052.373 N

R = 18,052.373 + 1.233 × 10⁴ ≈ 30,382.373

R ≈ 30,382.373 N

Taking moment about the point of attachment of the cable to the ground, we have;

W × ((d/2) × cos(60.0°) + 32) = R × 32

∴ (d/2) = ((30,382.373 × 32/18,052.373) - 32)/(cos(60.0°)) ≈ 43.71281

d = 2 × 43.71281 ≈ 87.43

The length of the flagpole, d ≈ 87.43 m
