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.
Explain how you would figure out ifc=4 is a solution to c + 5 = 13.
Answer:
Simple, plug 4 into c.
4 + 5 = 13
Is this true, no. So therefore c is not equal to 4.
There are 2 cars that are getting ready to race. After sitting at a stoplight for 30 seconds, the light turns green and they begin to accelerate at a rate of 4m/s2. The cars were neck and neck the whole way after traveling 150 meters. How long did it take them to travel that 150 meters?
Answer:
75secondsExplanation:
Given that the acceleration of the car is
a=4m/s^2
and also the distance covered is
d=150m
from the problem "The cars were neck and neck the whole way after traveling 150 meters"
this means velocity was constant throughout
s=ut+1/2at
150=0*t+4t/2
150=2t
divide both sides by 2
t=150/2
t=75seconds

A certain resistance thermometer reads 14. 5 Ω in pure melting ice and 18. 5 Ω in steam at standard atmospheric pressure. What will be its resistance at room temperature of 27. 0 o C ?
The resistance of the thermometer at the given temperature is 15.58 ohms.
Resistance of the thermometer
The resistance of the thermometer can be determined by applying method of interpolation as shown below;
[tex]\frac{R_\theta - R_0}{R_{100} - R_0} = \frac{\theta -0}{100 - 0}[/tex]
where;
Rθ is the resistance of the thermometer at 27⁰CR100 is the resistance at steam temperatureR0 is the ice temperature[tex]\\\\\frac{R_\theta - 14.5}{18.5 - 14.5} = \frac{27}{100} \\\\\frac{R_\theta - 14.5}{4} = \frac{27}{100}\\\\100R_\theta - 1450 = 108\\\\100R_\theta = 1558\\\\R_\theta = 15.58 \ ohms[/tex]
Thus, the resistance of the thermometer at the given temperature is 15.58 ohms.

1.What is light?
2.How light is being measured?
3.How light is being produced naturally and artificially?
4.How light is being detected?
5.What is the difference between light and ambient?
6.What are the modes of light sensors? Explain each.
Answer:
1. light is electromagnetic radiation within the portion of electromagnetic spectrum that is perceived by the human eye.
2. it's measured in footcandles or lux- it is the amount of light (lumens) falling on a Surface (over any given square foot or square meter). therefore, light intensity is measured in terms of lumens per square foot (footcandles) or lumens per square meter (lux).
3. natural light,, which produces heat and color comes from the radiation given off by the sun. It is then filtered through the Earth's atmosphere and absorbed by plants. Artificial light sources can consist of a filament that uses electricity or halogen gas to go or an electronic device that emits light.
4. most of our conscious vision stem from photoreceptors in the retina, the light-sensitive layer at the back of our eyeball. In animals with backbones (vertebrates) cells that detect light for vision are vaguely shaped like rods or cones giving them their familiar names.
5. there is a difference between ambient and task lighting. task lighting provides focus light so you can see better perform a certain task. while ambient fixtures offer general lighting for your home, distribute light evenly as well as helps create a mood.

Which statement describes dynamic equilibrium?
Answer:An object has balanced forces acting on it and constant velocity.
Explanation:
In a novel from 1866 the author describes a spaceship that is blasted out of a cannon with a speed of about 11.000 m/s. The spaceship is approximately 274 m long but part of it is packed with gunpowder, so it accelerates over a distance of only 213 m. What was the acceleration (in m/s2) experienced by the occupants of the spaceship during the launch?
Answer:
[tex]a=0.284\ m/s^2[/tex]
Explanation:
Given that,
Initially, the spaceship was at rest, u = 0
Final velocity of the spaceship, v = 11 m/s
Distance accelerated by the spaceship, d = 213 m
We need to find the acceleration experienced by the occupants of the spaceship during the launch. It is a concept based on the equation of kinematics. Using the third equation of motion to find acceleration.
[tex]v^2-u^2=2ad\\\\a=\dfrac{v^2-u^2}{2d}\\\\a=\dfrac{(11)^2-(0)^2}{2\times 213}\\\\a=0.284\ m/s^2[/tex]
So, the acceleration experienced by the occupants of the spaceship is [tex]0.284\ m/s^2[/tex].
Susan and Joe push a table 18 meters down a hall by exerting a force of 200
newtons What is the total amount of work done on the table
Answer:
50
Explanation:
prove that f=ma where the symbols have their usual meaning.
Explanation:
According to Newton's second law of motion:
Force is directly proportional to
Change of momentum/time taken
Change of momentum= mv-mu
where m is mass, u is initial velocity and v is final velocity. so,
F∝mv-mu/t
F∝m(v-u)/t
F∝ma (a=v-u/t)
F=kma where k is a constant
In SI units the value of k will become one so the equation will be:
F=ma

An air track car with a mass of 5-kg and velocity of 2 m/s to the right collides with a 3-kg car moving to the left with a velocity of 3 m/s. After the collision, the two cars bounce off of each other and the 5-kg car bounces back with a velocity of 1 m/s. What is the new velocity of the 3-kg car after the collision?
Answer: 2 m/s to the right
Explanation:
This is a conservation of momentum question:
p before = p after → m1v1 + m2v2 = m3v3 + m4v4
**Note- if the speed is to the left, plug in a negative v!
5(2) + 3(-3) = 5(-1) + 3(v4) → 1 = -5 + 3v4 → v4 = +2 m/s :)

write the ways to induce current in a circuit?
The following are the several approaches to produce a current in a coil:
An electric current is induced in a coil when it is rapidly moved between the two poles of a horseshoe magnet.
An electric current is induced when a magnet is shifted relative to a coil.
The current in the coil may be generated by keeping it fixed and rotating a magnet within it.
A steady alteration of the current in 'another coil' kept near it in a coil might create the current...
