What affect does doubling the net force have on the acceleration of the object (when
the mass of the object stays the same)? Identify a set of two trials that support your answer to question 1
===========================================================
Explanation:
Consider a mass of 10 kg, so m = 10
Let's say we apply a net force of 20 newtons, so F = 20
The acceleration 'a' is...
F = ma
20 = 10a
20/10 = a
2 = a
a = 2
The acceleration is 2 m/s^2. Every second, the velocity increases by 10 m/s.
---------------
Now let's double the net force on the object
F = 20 goes to F = 40
m = 10 stays the same
F = ma
40 = 10a
10a = 40
a = 40/10
a = 4
The acceleration has also doubled since earlier it was a = 2, but now it's a = 4.
---------------
In summary, if you double the net force applied to the object, then the acceleration doubles as well.
Acceleration is directly proportional to the net force on an object, and inversely proportional to its mass.
So if an object's mass stays the same while the net force on it doubles, then its acceleration will also double.
We don't know anything about the "trials". This sounds like it might be a follow-up to a lab experiment that was performed when we weren't there.

The atomic mass of an atom do not contain electrons because
Electrons do not exist in all atoms.
Electrons are so small that it does not affect the mass of an atom.
Electrons are do not contain mass.
Electrons are not as important as protons and neutrons.
Answer:
Electrons are so small that it does not affect the mass of atom .
Explanation:
Electrons are much smaller in mass than protons, weighing only 9.11 × 10^-28 grams, or about 1/1800 of an atomic mass unit. Therefore, they do not contribute much to an element's overall atomic mass.
Answer:
Electrons are so small that it does not affect the mass of an atom

A cannonball is launched straight up from the ground at 13.5 m/s. How much time is the cannonball in the air (hangtime)?
Answer:
Time in air t = 1.38 second (Approx)
Explanation:
Given:
Initial speed u = 0 m/s
Final speed v = 13.5 m/s
Find:
Time in air t
Computation:
v = u + gt
g = 9.8 m/s²
13.5 = 0 + (9.8)(t)
13.5 = 9.8 t
t = 13.5 / 9.8
t = 1.3777 second
Time in air t = 1.38 second (Approx)
Three people pull simultaneously on a stubborn donkey. Jack pulls directly ahead of the donkey with a force of 63.9 N63.9 N , Jill pulls with 79.1 N79.1 N in a direction 45° to the left, and Jane pulls in a direction 45° to the right with 183 N183 N . (Since the donkey is involved with such uncoordinated people, who can blame it for being stubborn?) Find the magnitude of the net force the people exert on the donkey.
Answer:
a) F = (137.4 i ^ + 185 j ^) N
b) F = 230.2 N , θ = 53.5º
Explanation:
In this exercise we ask to find the net force, for which we will define a coordinate system fix the donkey and use trigonometry to decompose the forces
Jack F₁ₓ = 63.9 N
Jill F₂ = 79.1 N with direction 45º to the left
cos (180 -45) = F₂ₓ / F₂
sin 135 = [tex]F_{2y}[/tex] / F₂
F₂ₓ = F₂ cos 135
F_{2y} = F₂ sin 135
F₂ₓ = 79.1 cos 135 = -55.9 N
F_{2y} = 79.1 sin 135 = 55.9 N
Jane F₃ = 183 N direction 45th to the right
cos 45 = F₃ₓ / F3
sin 45 = F_{3y} / F3
F₃ₓ = F₃ cos 45 = 183 cos 45
F_{₃y} = F₃ sin 45 = 183 sin 45
F₃ₓ = 129.4 N
F_{3y} = 129.4 N
we add each component of the force
Fₓ = F₁ₓ + F₂ₓ + F₃ₓ
Fₓ = 63.9 + (-55.9) + 129.4
Fₓ = 137.4 N
F_{y} = F_{2y} + F_{3y}
F_{2y} = 55.9 + 129.4
F_{2y} = 185.3 N
we can give the result of the forms
a) F = (137.4 i ^ + 185 j ^) N
b) in the form of module and angle
F = RA (Fₓ² + F_{y}²)
F = Ra (137² + 185²)
F = 230.2 N
tan θ = F_{y} / Fₓ
θ = tan⁻¹ F_{y} / Fₓ
θ = tan⁻¹ (185/137)
θ = 53.5º

How can you tell the difference between a colloid and a suspension?
Answer: Particles in a suspension are usually more than 1,000 nm, while those in a colloid range from 1-1,000 nm. Unlike those in a suspension, particles in a colloid do not separate when sitting still. ... Particles in a suspension can be seen by the naked eye, but those in a colloid must be viewed using a light microscope.

The frequency of a F-sharp sound wave in music is 370 Hz, and its wavelength is 0.93 m. what is the wave speed?
Answer:
wave speed =344.1 m/s
using v=fΠ
where v is the speed
The wave speed will be 344.1 m/sec. The wave speed is found as the product of the wavelength and the frequency of the wave.
What is wavelength?The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.
The wavelength is also defined as the distance between two locations in a wave that have the same oscillation phase.
The given data in the problem is;
v is the speed = ?
f is the frequency= 370 Hz
λ is the wavelength of the wave=0.96 m
The relationship between the wave's wavelength, frequency, and speed is given as;
wavelength = speed of wave / frequency
[tex]\rm \lambda = \frac{v}{f} \\\\ v = \lambda \times f \\\\ v = 0.93 \times 370 \ Hz \\\\ v= 344.1 \ m/sec[/tex]
Hence, the wave speed will be 344.1 m/sec.

A bomber is flying at a height of 9 km at 800 km/h. How far in front of the target should he drop his bombs?
Answer:
The distance in front of the target is 9.524 km
Explanation:
Given;
height of the bomber above the ground, h = 9 km = 9000 m
velocity of the bomber, v = 800 km/h = 222.22 m/s
The time the bomb will get to the target is given by;
[tex]t = \sqrt{\frac{2h}{g} } \\\\t = \sqrt{\frac{2*9000}{9.8} }\\\\ t = 42.857 \ s[/tex]
The lead distance or distance in front of the target is given by;
x = vt
x = (222.22 m/s) x (42.857 s)
x = 9523.68 m
x = 9.524 km
Therefore, the distance in front of the target is 9.524 km
In front of the target, the distance will be "9.524 km".
Distance and HeightAccording to the question,
Bomber's height, h = 9 km or,
= 9000 m
Bomber's velocity, v = 800 km/h or,
= 222.22 m/s
Now,
The time will be:
→ t = [tex]\sqrt{\frac{2h}{g} }[/tex]
By substituting the values, we get
= [tex]\sqrt{\frac{2\times 9000}{9.8} }[/tex]
= [tex]\sqrt{\frac{18000}{9.8} }[/tex]
= 42.857 s
hence,
The lead distance will be:
→ x = vt
By putting the values,
= 222.22 × 42.857
= 9523.68 or,
= 9.524 km
Thus the above answer is correct.
