Con el propósito de controlar las variables que influyen en la caída libre se provoca el vacío en la sala de un laboratorio. Si se dejan caer tres esferas, una de plomo, otra de aluminio y la última de plumavit, ¿en qué orden caerán las esferas si son soltadas desde una altura de 5 m?
Answer:
El plomo, el aluminio y la plumavit caerán al mismo tiempo.
Explanation:
En cinemática, la caída libre es un movimiento dónde solamente influye la gravedad. En este movimiento se desprecia el rozamiento del cuerpo con el aire, es decir, se estudia en el vacío.
La caída libre es un movimiento uniformemente acelerado de un cuerpo dónde solamente influye la gravedad y se estudia en el vacío, es decir, se debe despreciar el rozamiento del cuerpo con el aire. Entonces a este movimiento se denomina caída libre ideal. Y en esas condiciones, la aceleración que adquiriría el cuerpo sería debida exclusivamente a la gravedad, siendo independiente de su masa.
Entonces, el plomo, el aluminio y la plumavit caerán al mismo tiempo ya que adquirirían la misma aceleración, g, que es la aceleración de la gravedad.

What is convex lens ?An optical lens is made up of two spherical surfaces is convex lens The lens is called a biconvex lens or simply convex lens if those surfaces are curved outwards.
Converging lens is another name for it. It's because it brings all the light rays that are parallel to the primary axis together at the focus point (F).
The picture created by a convex lens is always real and inverted. The produced image is virtual and erect when the item is positioned between the focus and the optical center of the lens.

Light waves and sound waves have many similar behaviors, such as reflection and refraction. One behavior they do not share is
Answer:
light waves can travel in vacuum but sound waves require a medium to travel
also light waves are electromagnetic waves while sound waves are mechanical, light waves are transverse waves while sound waves are longitudinal waves
While sound waves are mechanical, light waves are electromagnetic. Unlike sound waves, which are longitudinal, light waves are transverse. Light waves can go across a vacuum. Since sound waves need a physical medium to move through, they cannot move in a vacuum.
What is sound wave?The pattern of disruption brought about by the movement of energy through a medium (such as air, water, or any other liquid or solid matter) as it spreads away from the source of the sound is known as a sound wave. Pressure waves are generated by item vibrations that cause sound waves, such as those from a ringing phone.
Unlike sound waves, which need a medium to propagate, light waves may travel in a vacuum.
Additionally, light waves are transverse waves whereas sound waves are longitudinal waves and light waves are electromagnetic waves.

Work is the application of force to move an object. It is proportional to both the force applied to the object and the distance it moves.
Net force = 96 N.
What is the relationship between work force and distance?Work is the application of force to move an object. It is proportional to both the force applied to the object and the distance it moves. This equation can be used to calculate work: Work = Force x Distance.The work done by a force of constant magnitude working in the strict direction of the object's velocity (however that changes) is magnitude of force times distance travelled.Positive Work : If a force moves an object in its direction, the work done is positive.Negative Work: Work is said to be negative if the force and displacement are in opposite directions.Mass m = 8 kg
Initial velocity = 6 m/s
Acceleration a = 12 m/s²
Time = 3 s
v = u + at
v = 6 + (12)(3)
v = 42 m/s
Work done = (1/2)(8)(42² - 6²)
Work done = 6,912
s = ut + (1/2)(a)(t)²
s = (6)(3) + (1/2)(12)(3)²
s = 18 + 54
Displacement (s) = 72 m
Net force = Work done / Displacement
Net force = 6,912 / 72
Net force = 96 N

A boat in the trough of a wave takes 3 seconds to reach the highest point of the wave. The velocity of the wave is 5 m/s. What is its wavelength?
Answer:
wavelength is equal to speed over frequency
A boat in the trough of a wave takes 3 seconds to reach the highest peak of the wave, then its wavelength will be equal to 30 m.
What is Frequency?The frequency of an event is its repetition per time unit. In a contrast to spatial frequency, it is also often referred to as temporal frequency, and in a contrast to angular frequency, it's often referred to as conventional frequency.
The standard unit is hertz (Hz), which is equal to one per second. The reciprocal of frequency is period, which itself is defined as the amount of time for one cycle of a repeating occurrence.
From the given data in the question,
Total time, t = 3s + 3s
t = 6 seconds.
Frequency, f = 1/6s
f = 0.1666 Hz
Now, let's find out the wavelength,
λ = υ/f
= 5/0.1666
λ = 30 m.
Therefore, the wavelength will be equal to 30 m.

statement is supported by the data in the table?
Answer: A
Explanation:
The guy above me was right
Motion is caused by the forces acting on a body. A body will move in the direction of in which the net force is greater. Therefore, objects 1 and 2 will not move but 3 and 4 will accelerate upward.
From the table ; the upward force of 18N is lesser than the force maintained by the objects at rest. Hence, objects 1 and 2 will not move.
However, objects 3 and 4 have forces 16N and 8N respectively which are lesser than the upward force, hence, the body will move upward since the upward force is greater.
Therefore, objects 1 and 2 will not move but 3 and 4 will accelerate upward.

Two friends are each driving a car down Highway 101. During a particular 10 s interval, Jodi's car moves at a constant 60 mph. During that same time interval, Julie's car transitions from a speed of 20 mph to a speed of 30 mph. Whose car has the greater acceleration?
Answer:
Julie's car.
Explanation:
The acceleration of an object is equal to the rate of change of velocity. It can be given by :
[tex]a=\dfrac{v-u}{t}[/tex]
Jodi's car moves at a constant 60 mph for 10 s.
Julie's car transitions from a speed of 20 mph to a speed of 30 mph for the same time interval i.e. 10 s.
For Jodi's car, the change in velocity is equal to 0. As a result, its acceleration is equal to 0 m/s².
For Julie's car,
Initial speed, u = 20 mph = 8.9408 m/s
Final speed, v = 30 mph = 13.4112 m/s
Acceleration,
[tex]a=\dfrac{13.4112-8.9408}{10}\\\\a=0.447\ m/s^2[/tex]
It is clear that Julie's car has the greater acceleration than the Jodi's car.

E = mgh
g is the acceleration due to gravity
We have,
E = 98.61 J, h = 4.3 m
Putting all the values to find m. So,
