When Anna eats an apple, the sugars in that apple are broken down into the substance called glucose. Glucose is then burned in h

er body for energy. One of the body parts that needs this energy is the heart, which beats due to electrical impulses. A byproduct of this glucose breakdown is the heat that warms her body and is later released. Which identifies the energy transformations that take place in Anna’s body as this process takes place? Mechanical energy is converted to kinetic energy, which is then converted to potential energy. Chemical energy is converted to thermal energy and electrical energy. Electrical energy is converted to chemical energy and thermal energy. Mechanical energy is converted to potential energy which is then converted to kinetic energy.

Answer:

Chemical energy is converted to thermal energy and electrical energy.

Explanation:

The sugar present in the apple is broken down into Glucose. This is chemical energy stored in the apple which is broken down into energy which is utilized by body for everyday works. The chemical energy gets converted to thermal energy which warms the body and electrical energy due to which the heart beats.

A body weighs 100newtons when submerged in water. calculate the upthrust action on the body​
Andrews [41]

Answer:

Upthrust = 20 N

Explanation:

The question says that "A body weighs 100N in air and 80N when submerged in water. Calculate the upthrust acting on the body ?"

Upthrust is defined as the force when a body is submerged in liquid, then liquid applies a force on it.

ATQ,

Weight of body in air is 100 N

Weight of body in water is 80 N

Upthrust is equal to the weight of body in air minus weight of body in water.

Upthrust = 100 N - 80 N

Upthrust = 20 N

So, 20 N of upthrust is acting on the body.

A box sliding on a horizontal frictionless surface runs into a fixed spring, compressing it a distance x1 from its relaxed posit
inn [45]

Answer:twice of initial value

Explanation:

Given

spring compresses x_1 distance for some initial speed

Suppose v is the initial speed and k be the spring constant

Applying conservation of energy

kinetic energy converted into spring Elastic potential energy

\dfrac{1}{2}mv^2=\dfrac{1}{2}kx_1^2----1

When speed doubles

\dfrac{1}{2}m(2v)^2=\dfrac{1}{2}kx_2^2----2

divide 1 and 2

\dfrac{1}{4}=\dfrac{x_1^2}{x_2^2}

x_2=2x_1

Therefore spring compresses twice the initial value

A pilot took 1/2 hour to complete 1/3 of his trip. How much longer will it take him to complete his trip?
katen-ka-za [31]

Answer: The answer is 1.5 hours.


Step-by-step explanation: Given that the pilot took 1/2 hour to complete 1/3rd of his trip. We are to calculate the time that he will take to complete his trip.

Time taken by the pilot to complete 1/3 rd of his trip = 1/2

Therefore, time taken by the pilot to complete his trip is given by

t=\dfrac{1}{2}\times 3=1.5.

Thus, the pilot will take 1.5 hours to complete his trip.

C= 5/9 (F−32) The equation above shows how temperature F, measured in degrees Fahrenheit, relates to a temperature C, measured i
iren [92.7K]

Answer:

option d) is correct

Explanation:

Given:

C = (5/9)(F-32)

For statement I

C = (5/9)F - (5/9)32

let the initial temperature in Fahrenheit  be 0

thus,

C = (5/9)(0) - (5/9)32 = - (5/9)32

for 1° increase in Fahrenheit

we get

C = (5/9)(1) - (5/9)32 = 1 - (5/9)32

thus,

on comparing the results, statement I is true

now for statement II

let the initial temperature in Celsius  be 0

thus,

0 = (5/9)(F) - (5/9)32

or

F =  (9/5)(5/9)32 = 32

for 1° increase in Celsius

we get

1 = (5/9)(F) - (5/9)32

or

(5/9)F = 1 + (5/9)32

or

F = (9/5) + 32

or

F = 1.8 + 32

thus,

on comparing the results, statement II is true

Now, for statement III

let the initial let the initial temperature in Fahrenheit  be 0

thus,

C = (5/9)(0) - (5/9)32 = - (5/9)32 = - 17.77

for (5/9)° increase in Fahrenheit

we get

C = (5/9)(5/9) - (5/9)32 = (0.3086) - 17.77 = -17.469

thus,

on comparing the results, statement III is false

Hence, option d) is correct
