Answer:

Explanation:

Relation between Celsius and Kelvin is

K = C + 273

Relation between Kelvin and Fahrenheit is

\frac{K-273}{100}=\frac{F -32}{180}

(a) 379 K

Relation between Celsius and Kelvin is

K = C + 273

So, C = K - 273 = 379 - 273 = 106

Thus, 379 K = 106°C.

(b) 379 K

Relation between Kelvin and Fahrenheit is

\frac{K-273}{100}=\frac{F -32}{180}

\frac{379-273}{100}=\frac{F -32}{180}

F = 222.8°F

Thus, 379 K = 222.8°F

(c) 1.04 x 10^2 K = 104 K

Relation between Celsius and Kelvin is

K = C + 273

So, C = K - 273 = 104 - 273 = -169

Thus, 104 K = - 169°C.

(d) 1.04 x 10^2 K = 104 K

Relation between Kelvin and Fahrenheit is

\frac{K-273}{100}=\frac{F -32}{180}

\frac{104-273}{100}=\frac{F -32}{180}

F =- 272.2°F

Thus, 104 K = - 272.2°F

g Drop the object again and carefully observe its motion after it hits the ground (it should bounce). (Consider only the first b
Anestetic [448]

Answer:

a) quantity to be measured is the height to which the body rises

b) weighing the body , rule or fixed tape measure

c)   Em₁ = m g h

d) deformation of the body or it is transformed into heat during the crash

Explanation:

In this exercise of falling and rebounding a body, we must know the speed of the body when it reaches the ground, which can be calculated using the conservation of energy, since the height where it was released is known.

a) What quantities must you know to calculate the energy after the bounce?

The quantity to be measured is the height to which the body rises, we assume negligible air resistance.

So let's use the conservation of energy

starting point. Soil

          Em₀ = K = ½ m v²

final point. Higher

          Em_f = U = mg h

         Em₀ = Em_f

         Em₀ = m g h₀

b) to have the measurements, we begin by weighing the body and calculating its mass, the height was measured with a rule or fixed tape measure and seeing how far the body rises.

c) We use conservation of energy

starting point. Soil

          Em₁ = K = ½ m v²

final point. Higher

          Em_f = U = mg h

         Em₁ = Em_f

         Em₁ = m g h

d) to determine if the energy is conserved, the arrival energy and the output energy must be compared.

There are two possibilities.

* that have been equal therefore energy is conserved

* that have been different (most likely) therefore the energy of the rebound is less than the initial energy, it cannot be stored in the possible deformation of the body or it is transformed into heat during the crash

A Texas rancher wants to fence off his four-sided plot of flat land. He measures the first three sides, shown as A, B, and C in
xz_007 [3.2K]
The answer:
the full question is as follow:
 <span>A Texas rancher wants to fence off his four-sided plot of flat land. He measures the first three sides, shown as A, B, and C in Figure below , where A = 4.90 km and θC = 15°. He then correctly calculates the length and orientation of the fourth side D. What is the magnitude and direction of vector D? 

As shown in the figure, 
A + B + C + D = 0, so to find the </span>magnitude and direction of vector D, we should follow the following method:
 D = 0 - (A + B + C) , 
let  W = - (A + B + C), so the magnitude and direction of vector D is the same of the vector W characteristics

Magnitude
 A + B + C = <span> (4.90cos7.5 - 2.48sin16 - 3.02cos15)I</span>
<span>+ (-4.9sin7.5 + 2.48cos16 + 3.02sin15)J
</span>= 1.25I +2.53J
the magnitude of W= abs value of (A + B + C) = sqrt (1.25² + 2.53²)
= 2.82
 
the direction of D can be found by using Dx and Dy value
we know that     tan<span>θo = Dx / Dy = 1.25 / 2.53 =0.49
</span>tanθo =0.49 it implies θo = arctan 0.49 = 26.02°

direction is 26.02°

Which process changes substances into new substances with new properties?
Y_Kistochka [10]

Answer:

The answer to your question is: Chemical change

Explanation:

Chemical Change  is a change where substances change their properties because new substances are obtain. This is the right answer.

Compressibility is a property in which a substance is compressed but it continous being the being so this answer is wrong.

Malleability  is a property in whcih substances are flattened into thin sheets but they don't change their properties. This answer is wrong.

Physical Change is a change in which a substance changes its physical state but the properties are the same than the original substance, this answer is wrong.

A 66.0 kg diver is 2.30 m above the water, falling at speed of 2.20 m/s. Calculate her kinetic energy as she hits the water. (Ne
fenix001 [56]

The kinetic energy of the diver as she hits the water is 159.72J. Details about kinetic energy can be found below.

<h3>How to calculate kinetic energy?</h3>

The kinetic energy of a body can be calculated using the following formula:

K.E = ½ × m × v²

Where;

  • K.E = kinetic energy
  • m = mass
  • v = velocity

According to this question, a 66.0 kg diver is 2.30 m above the water and falls at speed of 2.20 m/s.

Kinetic energy = ½ × 66 × 2.2²

K.E = 159.72J

Therefore, the kinetic energy of the diver as she hits the water is 159.72J.
