State the law of gravity, and explain how this paper airplane investigation
proved Newton's law of gravity.

Answers

Answer 1

Based on Newton's law of gravity, the force of attraction on the airplane moving on Earth is directly proportional to the mass of the airplane and inversely proportional to the square of distance the airplane from Earth's surface.

What is Newton's law of universal gravitation?

Newton's law of universal gravitation states that the force of attraction between two objects in the universe is directly proportional to the product of their masses and inversely proportional to the square of the distance between the two objects.

Mathematically, this law is written as follows;

Fg = ( G m₁ m₂ )  / ( r² )

where;

G is the universal gravitation constantm₁ is the mass of the first objectm₂ is the mass of the second objectr is the distance between the two objects

From Newton's second law of law of motion we will have;

F = mg

mg = ( G m₁ m₂ )  / ( r² )

g = Gm / r²

Every object on  Earth surface moves with equal acceleration due to gravity which has a value of 9.8 m/s².

Thus, airplane flying on Earth surface will be affected by gravity and the weight or downward force on the airplane is a function of gravity.

Answers

Answer:

c) It gets positively charged

Explanation:

If an electrically neutral body is loaded with protons so it gets positively charged because proton has positive charge. When the protons is added to the neutral body, it can't remain neutral because the quantity of positive charges increases in the nucleus and it gets positively charged while on the other hand, the atom from which protons are taken will acquire negative charge due to presence of more number of electrons and we know that electrons has negative charge.

the type of wave

Explanation:

Description: Doppler Effect works on both light and sound objects. For instance, when a sound object moves towards you, the frequency of the sound waves increases, leading to a higher pitch. Conversely, if it moves away from you, the frequency of the sound waves decreases and the pitch comes down.

A wave has a frequency of 60 Hz and a wavelength of 1.7 meters. What is the speed of this wave? equation, substitution

Answers

Answer:

v = 102 m/s

Explanation:

Given that,

The frequency of a wave, f = 60 Hz

Wavelength = 1.7 m

We need to find the speed of this wave. The formula for the speed of a wave is given by

[tex]v=f\lambda[/tex]

Substitute all the values,

[tex]v=60\times 1.7\\\\v=102\ m/s[/tex]

So, the speed of the wave is equal to 102 m/s.

f => is the frequency

From the equation i.e E = hf, we can conclude that the energy of a wave is directly proportional to it's frequency. This implies that an increase in the frequency of the wave will lead to an increase in the energy of the wave and also, a decrease in the frequency will lead to a decrease in the energy of the wave.

A young boy swings a yo-yo horizontally above his head so that the yo-yo has a centripetal acceleration of 200 m/s^2. If the yo-up’s string is 0.33 m long, what is the yo-up’s tangential speed?

Answers

Answer:

v = 8.12 m/s

Explanation:

The centripetal acceleration of the yo-yo is given by the following formula:

[tex]a_c = \frac{v^2}{r}\\\\v^2 = a_cr\\v = \sqrt{a_cr}[/tex]

where,

v = tangential speed = ?

ac = centripetal acceleration = 200 m/s²

r = radius = length of string = 0.33 m

Therefore, using the given values in the formula, we get:

[tex]v = \sqrt{(200\ m/^2)(0.33\ m)}[/tex]

v = 8.12 m/s

Air from a metal can is removed so the pressure in the can decreases to 70000Pa, the can is then sealed. The pressure from outside the can is atmospheric pressure which is 100kPa. The area of one side of the can is 1.5m2, find the resultant force on this side of the can.

Answers

Answer:

F = 45 KN = 45000 N

Explanation:

Considering the downward direction as the positive direction:

[tex]P = P_1 - P_2[/tex]

where,

P = Resultant Pressure = ?

P₁ = Atmospheric Pressure = 100 KPa

P₂ = Pressure inside the can = 70000 Pa = 70 KPa

Therefore,

[tex]P = 100\ KPa - 70\ KPa\\P = 30\ KPa[/tex]

Now the resultant force will be given as:

[tex]F = PA[/tex]

where,

F = resultant force = ?

A = Area of side of can = 1.5 m²

Therefore,

[tex]F = (30\ KPa)(1.5\ m^2)\\[/tex]

F = 45 KN

The energy of a single photon at the transmitted frequency is

A)3.55 × 10^(-28)J/photon

What is the energy of a single photon?

Energy of photon can be rewritten as

E=hv,

Where, h is planck's constant  

λ is the wavelength of photon  

Where f is the frequency of photon  

Thus, the energy of a single photon at the transmitted frequency obtained by using the formula, Energy (E) is equal to Planck's constant (h) times the frequency.

E=6.63×10^(-34)× 535×10^3

E =3.55 × 10^(-28) (J)
