According to the speed formula, distance that Tony ran at  a constant speed of 10 m/s for a total of 60 seconds is 600 meters.

The speed (commonly referred to as v) of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.The average speed of an object in an interval of time is the distance traveled by the object divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero. Speed is not the same as velocity.

Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second (m/s), but the most common unit of speed in everyday usage is the kilometre per hour (km/h) or, in the US and the UK, miles per hour (mph). For air and marine travel, the knot is commonly used.

Answer:

218.09g

Explanation:

the formula for density is mass/volume

you have volume so rlly what you have is 19.3g/cm3=m/11.3cm3

so mass equals density x volume

and 19.3 x 11.3 = 218.09

Answer:

Explanation:

The density of a substance can be found by using the formula

[tex]Density = \frac{mass}{volume} [/tex]

From the question

volume = 15 mL

mass of object = 8.7 g

We have

[tex]Density = \frac{8.7}{15} [/tex]

Explanation:

The limitations of model based on Experimental design and parameter

All models have limitations because they simplify complex real-world phenomena, omitting certain details or factors to make them manageable and understandable.

All models have limitations because they are simplified representations of complex systems or phenomena. To make models more manageable and understandable, certain details, variables, or interactions must be excluded.

This simplification can lead to discrepancies between the model and reality, limiting its accuracy and applicability. Additionally, models are often based on existing knowledge, which may be incomplete or subject to change.

As a result, models serve as valuable tools for understanding and prediction but should be used with caution, acknowledging their inherent simplifications and potential shortcomings when applied to real-world scenarios.

Density is the same

Explanation:

The density remains the same because cutting the object in half will divide the mass & volume by the same amount. Also, the density of a substance remains the same no matter what size it is.

Answer:

A. is not

B.  incorrect

C. identify substances that have the measured molecular mass

Explanation:

Since in the question it is mentioned that the Christy who is a forensic scientist and she gave a white powder and identify whether it is a sugar or not when she tested she seen that the molecular mass is different as compared with the sugar

So here it can be concluded that the white powder does not show a sugar that means it is not a sugar so automatically the hypothesis of Christy is wrong. And, the next step is to track the substance that shows the molecular mass i.e. measured

Answer:

- is not

-incorrect

- identify substances that have the measured molecular mass

Explanation:

Answer:

The answer is

Explanation:

The density of a substance can be found by using the formula

[tex]Density = \frac{mass}{volume} [/tex]

From the question

mass = 45 g

volume = 4 mL

Substitute the values into the above formula and solve for the density

The functional unit is called a system.

The stomach, small intestine, and large intestine are all organs. When they work together to process food, they form a functional unit known as a system. The correct option is b.

The living body performs many functions. These functions are performed by different systems of the body. There are many systems in the body.

These systems are digestive systems, reproductive systems, circulatory systems, etc. These systems run the body and make an organism.

Here, the stomach, small intestine, and large intestine are all organs of the digestive system. Digestive system digest the food that we eat and provides us energy and removes the waste material from the excretory system, which excretes it out of the body.

Answer:

1 litre = 1000 millilitres

Answer:

iron, it is more dense than aluminum

Explanation:

Answer:

Aluminium

Explanation:

Responda:

+ 0,9kJ / mol

Explicação:

Dados os calores de combustão do enxofre monoclínico e enxofre rômbico como - 297,2 kJ / mol e - 296,8 kJ / mol, respectivamente para a variação na transformação de 1 mol de enxofre rômbico em enxofre monoclínico conforme mostrado pela equação;

S (mon.) + O2 (g) -> SO2 (g)

Uma vez que são todos 1 mol cada, a mudança na entalpia será expressa como ∆H = ∆H2-∆H1

Dado ∆H2 = -296,8kJ / mol

∆H1 = -297,2kJ / mol

∆H = -296,8 - (- 297,2)

∆H = -296,8 + 297,2

∆H = 297,2-296,8

∆H = + 0,9kJ / mol

Portanto, a mudança na entalpia da equação é + 0,9kJ / mol

Explanation:

The more gravity pulls down on an object it gets heavier. Weight is just the amount of force gravity is putting on something. So if gravity is pulling it down more ut would get heavier.

Answer:

False
