A farmer is walking through a field at a
velocity of +0.5 meters per second (m/s)
relative to the ground. At the same time, he
is throwing seeds in front of him at a
velocity of +2.1 m/s relative to himself.
What is the velocity of the seeds relative to
the ground as they travel through the air?
Answer:
The velocity of the seeds relative to the ground as they travel through the air is V = +2.6 m/s
Explanation:
Let V be the velocity of the seeds relative to the ground, v be the velocity of the seeds relative to the farmer and v' be the velocity of the farmer relative to the ground.
By vector addition, V = v + v'
Since v = the velocity of the seeds relative to the farmer = +2.1 m/s and
v' = the velocity of the farmer relative to the ground = +0.5 m/s
Then,
V = v + v'
V = +2.1 m/s + (+0.5 m/s)
V = +2.6 m/s
So, the velocity of the seeds relative to the ground as they travel through the air is V = +2.6 m/s

When the cornea and lens of the eye do not properly focus
light onto the retina, corrective lenses are needed. When are concave lenses
appropriate for vision correction?
Answer:
When there is nearsightedness or myopia
Explanation:
As, in myopia the image is formed in front of the retina.
Which makes things looking at things near very easy, but looking at far away things very difficult.
So concave lens makes things look bigger, so therefore, it is used during myopia, to make things look bigger when they are far away

A car runs for about 10 years during its average useful life. If the odometer reads 120,000 miles at the end, what was the average speed of the car in mph
Answer:
12000 mph
Explanation:
Given that,
Distance read by the odometer = 120,000 miles
Duration of car, t = 10 years
We need to find the average speed of the car. Speed of an object is equal to the total distance covered divided by total time taken. So,
[tex]v=\dfrac{120000}{10}\\\\=12000\ mph[/tex]
So, the average speed of the car is 12000 mph.

Explanation:
Ana vive a 3 km del instituto y María en la misma carretera, 500 m. Más lejos. Todas las mañanas, a las ocho y cuarto, cogen la bici para ir a clase. Ana pedalea a 6 m/s y María a 8 m/s. A) ¿Cuándo y dónde se encuentran? B) A que velocidad tendría que pedalear Ana como mínimo para que María no la alcanzase antes de llegar al instituto
Answer:
A) Ana y María e encuentran a las 8 hs 19 minutos 10 segundos (250 segundos después).
María y Ana se encuentran cuando aún faltan 1500 metros para llega al instituto.
B) Ana tendría que pedalear como mínimo para que María no la alcanzase antes de llegar al instituto a una velocidad de 6.857 [tex]\frac{m}{s}[/tex].
Explanation:
A) Un movimiento es rectilíneo cuando un objeto describe una trayectoria recta, y es uniforme cuando su velocidad es constante en el tiempo. En otras palabras, el Movimiento Rectilíneo Uniforme es una trayectoria recta, su velocidad es constante y su aceleración es nula.
Para una posición inicial x0 y una velocidad v que tiene el cuerpo a lo largo del movimiento, la posición para cualquier tiempo está dada por:
x(t)= x0 + v*t
Estableciendo el origen de referencia en el instituto, se tienen los siguientes valores:
x0ana= 3 km= 3000 mx0maria= 3500 mPor otro lado, Ana pedalea a 6 m/s y María a 8 m/s.
Entonces, como Ana y María se acercan al origen de referencia, la escuela, se la ecuación del movimiento para cada una de ellas es:
xana= 3000 - 6*txmaria= 3500 - 8*tAmbas se encuentra cuando la posición de ellas sea la misma, esto es xana=xmaria. Entonces:
3000 -6*t= 3500 - 8*t
Resolviendo:
-6*t + 8*t= 3500 - 3000
2*t= 500
t= 500÷2
t=250 s= 4 minutos 10 segundos
Ana y María se encuentran a las 8 hs 19 minutos 10 segundos (250 segundos después).
Para conocer la posición en la que se encuentran debes sustituir el tiempo en la ecuación del movimiento de alguna de ellas:
xana=3000 - 6*250
xana= 1500 m
Es decir, María y Ana se encuentran cuando aún faltan 1500 metros para llega al instituto.
B) Para que esto ocurra Ana y María deben llegar al instituto al mismo tiempo. Entonces, el tiempo que tarda María en llegar a al origen de referencia, la escuela, es:
0= 3500 - 8*t
Resolviendo:
3500=8*t
3500÷8= t
437.5 segundos= t
Así que, si Ana 437.5 segundos o menos, María no la alcanzaría. Siendo la velocidad la relación entre el espacio recorrido por un objeto y el tiempo empleado para ello, entonces la velocidad de Ana se calcula como:
[tex]velocidad=\frac{distancia}{tiempo}[/tex]
[tex]velocidad=\frac{3000 metros}{437.5 segundos}[/tex]
velocidad= 6.857 [tex]\frac{m}{s}[/tex]
Ana tendría que pedalear como mínimo para que María no la alcanzase antes de llegar al instituto a una velocidad de 6.857 [tex]\frac{m}{s}[/tex].

Hallar la fuerza eletrica ejercida entre 2 cargas iguales de magnitud 1c separado en el aire una distancia de 1km Cual es el resultado? 1. (2,3*10^-8new) 2. (8,1*10^-6new) 3. (3,2*10^-8new)
Answer:
La fuerza eléctrica ejercida entre 2 cargas iguales de magnitud 1 C separado en el aire una distancia de 1 km es 9,000 N.
Explanation:
La ley de Coulomb se utiliza para calcular la fuerza eléctrica que actúa entre dos cargas en reposo. Es decir, esta ley permite predecir la fuerza electrostática de atracción o repulsión existente entre dos partículas según su carga eléctrica y la distancia entre ellas.
La fuerza eléctrica con la que dos cargas puntuales son atraídas o repelidas en reposo es directamente proporcional a su producto e inversamente proporcional al cuadrado de la distancia que las separa, expresada como:
[tex]F=k*\frac{q1*q2}{d^{2} }[/tex]
donde:
F es la fuerza eléctrica de atracción o repulsión. En el S.I. se mide en Newtons (N). q1 y q2 son lo valores de las dos cargas puntuales. En el S.I. se miden en Culombios (C). d es el valor de la distancia que las separa. En el S.I. se mide en metros (m). k es una constante de proporcionalidad llamada constante de la ley de Coulomb. Depende del medio en el que se encuentren las cargas. En concreto para el vacío k es aproximadamente 9*10⁹ N·m²/C² utilizando unidades en el S.I.En este caso:
q1= 1 Cq2= 1 Cd= 1 km= 1,000 mReemplazando:
[tex]F=9*10^{9} \frac{N*m^{2} }{C^{2} } *\frac{1 C* 1 C}{(1,000 m)^{2} }[/tex]
Resolviendo obtenes:
F= 9,000 N
La fuerza eléctrica ejercida entre 2 cargas iguales de magnitud 1 C separado en el aire una distancia de 1 km es 9,000 N.

Two cars, initially 12 meters apart, zip towards one another at the speeds shown. At what point will the collision occur? Explain how you arrived at your answer. Car A: 1.4m/s car B: 2.2m/s
Answer:
s₁ = 4.67 m from car A
Explanation:
Since, the cars are moving at a constant speed. Hence, we will apply the equation for uniform motion here:
s = vt
where,
s = distance covered
v = velocity
t = time taken
For Car A:
s₁ = (1.4 m/s)t
For Car B:
s₂ = (2.2 m/s)t
Because the time will be same at the collision. At collision the distance covered by Car A and Car B must be 12 m altogether. Hence:
s₁ + s₂ = 12 m
using values:
(1.4 m/s)t + (2.2 m/s)t = 12 m
t = 12 m/3.6 m/s
t = 3.333 s
Substitute this in the equation of s₁:
s₁ = (1.4 m/s)(3.33 s)
s₁ = 4.67 m from car A
