Answer:

Fue mas velóz en los 100 m.

[tex]v_{1}=9.47\: m/s[/tex]

Explanation:

Tomando en cuanta que la definición de velocidad es:

[tex]v=\frac{\Delta x}{t}[/tex]

Donde:

La primera velodcidad esta dada por:

[tex]v_{1}=\frac{100}{10.56}[/tex]

[tex]v_{1}=9.47\: m/s[/tex]

La segunda velocidad sera:

[tex]v_{1}=\frac{200}{22.34}[/tex]

[tex]v_{1}=8.95\: m/s[/tex]

Por lo tanto, en el primer tramo fue más rápido.

Answer:

d = 18 m

Explanation:

Given that,

The speed of a baseball, v = 36 m/s

We need to find the distance from the mound to home plate if the ball takes 0.5 seconds to leave the pitcher's hand and cross the plate.

Let the distance be d. We can find it using the formula,

Speed = distance/time

or

[tex]d=vt\\\\d=36\times 0.5\\\\d=18\ m[/tex]

So, the required distance is equal to 18 m.

Explanation:

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

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.

Answer:

A) Three hole punch and either a layered plastic or paper

B) Identify the lengths involved  ,

  Length of input arm / length of output arm = L1/ L2

Explanation:

a) Materials involved includes :

Three hole punch and either a layered plastic or paper

Identify the forces acting on the three-hole punch which are Input and output forces

Identify the points where they act

B) procedures involved

The mechanical advantage = output force / input force

step one:  Identify the lengths involved

assuming no friction or relatively small friction \

mechanical advantage can be calculated as : Length of input arm / length of output arm = L1/ L2

Answer: Start at the top of the hill.

Explanation:

The options include:

a. Start at the bottom of the hill.

b. Start at the top of the hill.

c. Start in the middle of the hill.

Sled racing is simply a winter dog sport racing. Since Robb wants to win the next sled race, the advice that'll be given to him is that he should start at the top of the hill.

Other options such as starting at the bottom of the hill or the middle of the hill are wrong.

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

Answer:

Temperature, T2 = 300 Kelvin

Explanation:

Given the following data;

Initial volume = 100 Liters

Initial temperature = 200 Kelvin

Final volume = 150 Liters

To find the final temperature T2, we would use Charles' law.

Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Charles is given by;

[tex] \frac {V}{T} = K[/tex]

[tex] \frac{V1}{T1} = \frac{V2}{T2}[/tex]

Making T2 as the subject formula, we have;

[tex] T_{2}= \frac{V_{2}}{V_{1}} * T_{1}[/tex]

Substituting into the formula, we have;

[tex] T_{2}= \frac{150}{100} * 200[/tex]

[tex] T_{2}= 1.5 * 200 [/tex]

Temperature, T2 = 300 Kelvin

Answer:

valence

Explanation:

Explanation:

The amount of CD is 35 g, and the amount of AC is 40 g.

Explanation:

AB + CD \rightarrow AC + BDAB+CD→AC+BD

The law of conservation of mass states that in any chemical reaction, the total mass of the reactants must be equal to the total mass of the products.

In this reaction, we know the mass of one reactant (AB, 15 g) and the mass of one product (BD, 10 g). In order to have the same total mass on the left side and on the right side of the equation, the mass of AC must be 5 g more than the mass of CD. We see that the only choice that satisfies this condition is:

The amount of CD is 35 g, and the amount of AC is 40 g.

In fact, if we assume these masses are correct, we have:

- on the reactant side: m(AB)+m(CD)= 15g + 35g = 50g

- on the product side: m(AC)+m(BD)= 40g + 10g = 50g

so, we have the same mass on both sides of the equation, and the law of conservation of mass is satisfied.

Answer:

B is  the answer on edge

Explanation:

B: The amount of CD is 35 g, and the amount of AC is 40 g.
