Explain how the fountain pen is filled up with ink
Answer:
It is because of air pressure
Explanation:
Filling a fountain pen with ink involves various methods, but the most common approach uses a piston or converter mechanism.
To begin, the pen is prepared by removing the cap and separating the barrel from the grip section. The type of filling system is checked, whether it's a built-in piston or a removable converter.
For a piston-filling method, the knob is twisted counterclockwise to retract the piston. The nib is submerged in the ink bottle, and by turning the knob clockwise, the piston extends, creating a vacuum that draws ink into the reservoir through capillary action.
The piston is then retracted, sealing the ink inside. In the case of a converter, it is removed from the grip section and dipped into the ink bottle, followed by operating the plunger or squeezing to expel air.
Releasing the plunger allows ink to enter the converter through atmospheric pressure. After cleaning any excess ink, the pen is reassembled.

Do Planets with more mass have more gravity than planets with less mass
A ball with a weight of 70 N hangs from a string that is coiled around a 3 kg pulley with a radius of 0.4 m. Both the ball and the pulley are initially at rest. The rotational inertia of the pulley is 0.5mr2 and the ball is released from rest. Calculate the ball's velocity after it falls a distance of 2 meters.
Answer:
v = 6.195 m / s
Explanation:
For this exercise we can use the conservation of energy, for the system formed by the ball and the pulley
starting point. Higher before releasing the system
Em₀ = U = M g h
final point. When the ball has lowered h = 2
Em_f = K = ½ M v² + ½ I w²
the energy is preserved
Em₀ = Em_f
M g h = ½ M v² + ½ I w²
angular and linear velocity are related
v = w r
w = v / r
indicate that the moment of inertia is
I = ½ m r²
we substitute
M g h = ½ M v² + ½ (½ m r²) (v/r) ²
½ v² (M + [tex]\frac{1}{2}[/tex] m) = M g h
v² = [tex]2gh \ \frac{M}{M + \frac{m}{2} }[/tex]
let's calculate
v = [tex]\sqrt{ 2 \ 9.8 \ 2 \ \frac{70}{70 + 1.5} }[/tex]
v = 6.195 m / s

A student wearing in-line skates pushes against a brick wall. why does the student move away from the wall ?
1. Because the forces acting on the student are balanced
2. Because the forces acting on the student are creating a net force
3. Because gravity is less than the student's push on the wall
4. Because the friction between the skates and the pavement is greater than the student's push on the wall

Relative velocity: An airplane flies between two points on the ground that are 500 km apart. The destination is directly north of the origination of the flight. The plane flies with an air speed of 120 m/s. If a constant wind blows at 10.0 m/s due west during the flight, what direction must the plane fly relative to north to arrive at the destination
Answer:
4.78 degrees east of north
Explanation:
The computation is shown below:
The Speed of the plane is 120 m/s
The Speed of the wind is 10 m/s
Sin [tex]\theta[/tex] = 10 ÷ 120
= 1 ÷ 12
= 0.0833
Now
\theta = 4.78 degrees
It should be 4.78 degrees east of north
Since the wind blows due west plane and it should fly east of north to reach at the final destination
Temperature is a measure of the average *blank*
energy of particles in a substance.
Answer:
Kinetic.
Explanation:
Temperature can be defined as a measure of the degree of coldness or hotness of a physical object. It is measured with a thermometer and its units are Celsius (°C), Kelvin (K) and Fahrenheit (°F).
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Generally, temperature measures the average kinetic energy of particles in a particular substance. Also, when the temperature of a particular substance is greater than absolute zero, it is said to possess kinetic energy.
Additionally, conduction involves the transfer of electric charge or thermal energy due to the movement of particles.
In the process of heat conduction, thermal energy is usually transferred from fast moving particles to slow moving particles during the collision of these particles. Also, thermal energy is typically transferred between objects that has different degrees of temperature and materials (particles) that are directly in contact with each other but differ in their ability to accept or give up electrons.
The term "temperature" refers to a measurement of how cold or hot an actual physical object is. It is measured with a thermometer, which gives readings in Celsius, Kelvin, and Fahrenheit (°C, K, and °F).
Thus, An energy that an object or body possesses as a result of its motion is known as kinetic energy.
The average kinetic energy of the particles in a given substance is often measured by temperature. Additionally, a substance is said to have kinetic energy when its temperature is higher than absolute zero.
Conduction also entails the transmission of heat or electric charge as a result of the motion of particles. Thermal energy is typically transmitted from quickly moving particles to slowly moving particles during a collision in the process of heat conduction.
Thus, The term "temperature" refers to a measurement of how cold or hot an actual physical object is. It is measured with a thermometer, which gives readings in Celsius, Kelvin, and Fahrenheit (°C, K, and °F).

Refracts light to form an image on the lining of your eyeball?
Answer:
In a healthy eye, the cornea bends or refracts light rays so they focus precisely on the retina in the back of the eye. The back of the eye is lined with a thin layer of tissue containing millions of photoreceptor (light-sensitive) cells. This is the retina, where light rays focus into an upside-down image.

Answer:
m = 0.01 kg
Explanation:
Given that,
Momentum of the marble, p = 0.15 kg-m/s
Speed of the marble, v = 15 m/s
We need to find its mass. We know that,
Momentum, p = mv
Where
m is the mass
[tex]m=\dfrac{p}{v}\\\\m=\dfrac{0.15}{15}\\\\m=0.01\ kg[/tex]
