Answer:

A 19.45-inch-long segment of the same rope would weigh 32.92 ounces.

Explanation:

You know that:

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other), knowing the values ​​a, b and c and x being the unknown, we must apply the direct rule of three as follows:

a ⇒ b

c ⇒ x

So [tex]x=\frac{c*b}{a}[/tex]

To find the number of ounces a 19.45-inch length of the same string would weigh, you apply the following rules of three:

[tex]centimeters=\frac{19.45 inch*2.54 centimeters}{1 inch}[/tex]

centimeters=49.403

[tex]grams=\frac{49.403 centimeters*61.40 grams}{3.25 centimeters}[/tex]

grams= 933.34

[tex]ounces=\frac{933.34 grams*1ounce}{28.3495 grams}[/tex]

ounces= 32.92

A 19.45-inch-long segment of the same rope would weigh 32.92 ounces.

The digital signals are generally in the form of zeros and ones.

The digital signals turn sounds into zeros and ones.

An electronic signal is transmitted as binary code that can be either the presence or absence of current, high and low voltages, or short pulses at a particular frequency. This signal is called a Digital Signal.

Digital signals take value in discrete form only at a given time.

Any digital signal can be converted into an analog signal with the help of a digital to analog converter.

If the sound signal is in the form of a digital signal, then it will turn the sound into the form of zeros and ones.

To be 100% honest im nkt sure but I'm gonna take a gander. yes i think it is the same

Answer:

Yes heat is the same as thermal energy

Explanation:

Heat is the same thing as thermal because Thermal energy refers to the energy contained within a system that is responsible for its temperature. Heat is the flow of thermal energy. A whole branch of physics, thermodynamics, deals with how heat is transferred between different systems and how work is done in the process (see the 1ˢᵗ law of thermodynamics).

Answer:

Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force

Answer:

An object in motion will stay in motion unless acted on by an unbalanced force.

An object at rest will stay at rest unless acted on by an unbalanced force.

An object in motion will stay in motion, and an object at rest will stay at rest unless acted on by an unbalanced force

(There are three parts to Newton’s First Law of Motion)

We have no idea what those "following variables" are.  You faded out right at the point where you were supposed to show them to us.

The period of a simple pendulum only depends on its length, and the acceleration of gravity in the place where the pendulum is swinging.

It's really tough to answer the question, because both of these things are in a fraction in the formula for the period . . . the length is the numerator, and the local acceleration of gravity is the denominator.  So which one has a greater effect on the period really depends on what those numbers are before anything changes.  

Answer:

EMS waves require no material medium to travel

Explanation:

Here, we want to consider the difference between mechanical waves and EMS waves

When we talk of EMS waves, we mean electromagnetic radiation waves .

Example of EMS waves include radio waves , x-rays etc

These kind of waves require no material medium to travel and this is the main difference they have with mechanical waves

Answer:

Explanation:

There are two forces on the box.  Weight force pulling down and resistive force pushing up.

Sum of forces in the y direction:

∑F = ma

F − mg = ma

F = mg + ma

F = m (g + a)

F = (300 kg) (9.8 m/s² + (-2 m/s²))

F = 2340 N

Answer:

Explanation:

height of one floor = 3.01 m

height of 96 floor h = 96 x 3.01 = 288.96 m

time of fall t = 12.6 s

h = 1/2 g x t²

288.96 = 1/2 x g x 12.6²

g = 3.64 m /s²

v = u + gt

v = 0 + 3.64 x 12 .6

= 45.86 m /s

velocity of impact = 45.86 m /s .

Answer:

If an atom loses or gains electrons, it becomes an ion with a positive or negative charge. So an ion is a special case of an atom when it has a total charge that is not zero. Usually if someone is talking about an atom with a positive or negative total charge, they will call it an ion rather than just an atom

2 for water(H2O)

1 for oxygen (O2)

Explanation:

This question is describing the decomposition of hydrogen peroxide (H2O2). Hydrogen peroxide (H2O2), which is the reactant gets broken down into water (H2O) and oxygen gas (O2). The chemical equation is as follows:

2H2O2 ---> 2H2O + O2

As described in the question, the amount of oxygen in the reactants (H2O2) is 4 atoms. The products are water and oxygen gas. To ensure that the equation is balanced, we have to use coefficients.

- Coefficient 2 has been placed in front of the water molecule to balance the number of hydrogen atoms (4) and oxygen atoms (4).

- The coefficient in front of the Oxygen gas remains 1.

Answer:

A. 28 m/s

B. 5.72 s

Explanation:

The following data were obtained from the question:

Maximum height (h) = 40 m

Acceleration due to gravity (g) = 9.8 m/s²

A. Determination of the initial velocity.

Maximum height (h) = 40 m

Acceleration due to gravity (g) = 9.8 m/s²

Velocity at maximum height (v) = 0 m/s

Initial velocity (u) =.?

v² = u² – 2gh (Ball is going against gravity)

0² = u² – (2 × 9.8 × 40)

0 = u² – 784

Collect like terms

0 + 784 = u²

784 = u²

Take the square root of both side

u = √784

u = 28 m/s

Thus, the ball was kicked with a velocity of 28 m/s

B. Determination of the time of flight.

We'll begin by calculating the time taken to reach the maximum height. This can be obtained as follow:

Velocity at maximum height (v) = 0 m/s

Initial velocity (u) = 28 m/s

Time taken to reach the maximum height (t) =?

v = u – gt (Ball is going against gravity)

0 = 28 – 9.8t

Rearrange

0 + 9.8t = 28

9.8t = 28

Divide both side by 9.8

t = 28/9.8

t = 2.86 s

Finally, we shall determine the the time of flight as follow:

Time taken to reach the maximum height (t) = 2.86 s

Time of flight (T) =?

T = 2t

T = 2 × 2.86

T = 5.72 s

Therefore, the time of flight for the ball is 5.72 s

Complete question is;

Most people can throw a baseball farther than a bowling ball, and most people would find it less painful to catch a flying baseball than a bowling ball flying at the same speed as the baseball. Explain these two apparent facts in terms of

a.) Newtons first law of motion

b.) Newtons Second law of motion

Answer:

A) Explained below

B) Explained below

Explanation:

A) The statement given is that most people find it less painful catching a flying baseball than a bowling ball flying at the same speed as the baseball.

Newton's first law states that an object at rest will continue at rest or if in motion will continue in constant motion unless an external force acts on it.

This means that the velocity has to be constant and net force is zero.

It therefore means that people will need to apply plenty of force on the bowling ball with a constant velocity in order to maintain net force equal to zero.

B) Newton's second law of motion states that force is equal to the rate of change in momentum.

The given statement in the question is true because of the amount of mass and force needed to be applied.

Now, due to the fact that the bowling ball will require a lot of force to be applied on it, it will be hard for people to throw it easily. Thus, it will be easier for most people to throw the baseball than the bowling ball
