Answer:

The car drives 108 m

Answer:

[tex]604000\ \text{J}[/tex]

Explanation:

m = Mass of ice = 200 g

[tex]\Delta T[/tex] = Temperature change of water = [tex](100-0)^{\circ}\text{C}[/tex]

c = Specific heat capacity of water = 4200 J/kg °C

[tex]L_f[/tex] = Specific latent heat of fusion = 340 kJ/kg

[tex]L_v[/tex] = Specific latent heat of vaporisation = 2260 kJ/kg

Heat required to convert ice to water = [tex]mL_f[/tex]

Heat required to raise the temperature of water to boiling point = [tex]mc\Delta T[/tex]

Heat required to convert water to steam = [tex]mL_v[/tex]

Total heat required

[tex]q=mL_f+mc\Delta T+mL_v\\\Rightarrow q=m(L_f+c\Delta T+L_v)\\\Rightarrow q=0.2(340\times 10^3+4200(100-0)+2260\times 10^3)\\\Rightarrow q=604000\ \text{J}[/tex]

Heat required to convert the given amount of ice to steam at the required temperature is [tex]604000\ \text{J}[/tex].

Explanation:

Assuming the English system of mass and weight is the same as the Imperial system, the measurements are:

• 1 pound (lb) = 16 ounces (oz)

• 2,000 pounds (lbs) = 1 ton (T)

I think that's everything?

In the English system, mass is measured in pounds and weight is also measured in pounds. However, it is important to understand the difference between mass and weight.

Mass is a measure of the amount of matter in an object and is a scalar quantity. It does not change with location or gravitational force. In the English system, mass is typically measured using a scale or balance, which compares the object's mass to a standard mass. The pound (lb.) is the unit of mass in the English system.

Weight, on the other hand, is a measure of the force exerted on an object due to gravity and is a vector quantity. It depends on the object's mass and the gravitational force acting on it. In the English system, weight is typically measured using a spring scale or a balance that incorporates a spring. The pound (lb.) is also used as the unit of weight in the English system.

Weight = Mass x Acceleration due to gravity

Mass is measured in pounds (lb.) and weight is also measured in pounds (lb.).It is important to note that weight can vary depending on the gravitational force acting on an object.

Answer:

True

Explanation:

This heat energy allows the change of state to happen, and the temperature remains constant during the process. The amount of energy required to change the state of a substance depends upon the mass and characteristics of that substance. The energy required to change the state of a material is known as the latent heat. During a change of phase the temperature does not change, but the internal energy does. The internal energy is the sum of the kinetic energy of the molecules and the chemical potential energy of the molecules.

Answer:

t = 3.52 s

Explanation:

Given that,

The deceleration of a car is, a = -1.7 m/s²

The initial velocity of the car, u = 15 m/s

Final velocity of the car, v = 9 m/s

We need to find the time that is required to slow the car from 15 m/s to 9 m/s. The definition of acceleration is :

[tex]a=\dfrac{v-u}{t}\\\\t=\dfrac{v-u}{a}\\\\t=\dfrac{9-15}{-1.7}\\\\t=3.52\ s[/tex]

So, it will take 3.52 seconds to slow the car from 15 m/s to 9 m/s.

Answer: 500 ft

Explanation:

High beam headlights help one to see better at night as the range of vision is greatly expanded. They can however, blind drivers coming on the opposite lane.

It is therefore prudent to ensure that when using high beam headlights, you dim them when a car is coming towards you. The appropriate distance to do so is a minimum of 500 ft from the car.

Answer:

Square Meters to Square Centimeters Conversion

1 Square meter (m2) is equal to 10000 square centimeters (cm2). ... For example, to convert 10 m2 to cm2, multiply 10 by 10000, that makes 100000 cm2 is 10 m2.

cm2↔mm2 1 cm2 = 100 mm2.
