Answer:
pursuing a goal
Explanation:
Since there are no answer choices provided I would say that this is an example of pursuing a goal. This is basically all of the tasks and struggles that an individual must go through in order to finally achieve a certain goal. It also involves gradually breaking barriers and pushing forward by increasing the complexity of the tasks until you are able to break through all of them to reach the end-goal that you have been striving for. Which is exactly what John has been doing in this scenario by gradually increasing his running time.

Explanation:
I took 2 hrs I tried on this for u dont get mad have a wonderful day :D
So the incorrect option is C the current flowing through the circuit is 27 amps because the current is related to voltage and resistance by the formula I = R + V
What is resistance?Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω).
Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.
Ohm's Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit.
To students of electronics, Ohm's Law (E = IR) is as fundamentally important as Einstein's Relativity equation (E = mc²) is to physicists.
E = I x R
So the incorrect option is C the current flowing through the circuit is 27 amps because the current is related to voltage and resistance by the formula I = R + V

what is the what is the name of the new palace of Londonwhy it make kota kota kota kota
Answer:
Engraving of the city of Kota from the east by Edward Francis Finden (1791-1857) and Patrick Young Waugh (1788-1829). Plate 2 of the 'Annals and antiquities of Rajast'han or the Central and Western Rajpoot States of India' published in London in 1832.
The Rajput city of Kota in southern Rajasthan was founded in the 14th century within the borders of the state of Bundi; it became the capital of an independent princely state of the same name in the early 17th Century. During the reign of the Mughal Emperor Jahangir, Rao Ratan Singh, the ruler of Bundi, gave the small principality of Kota to his son, Madho Singh. The Kota fort he gained possession of was built in c. 1264 by Rajkumar Jait Singh of Bundi and contains the city palace. It is situated on the bank of the River Chambal where it meets its tributary, the Shahi Dehra. This engraving shows a view of the Chambal with the ramparts and bastions of the fort rising from the rivers edge behind.

How many times more gravitational potential energy would the same lander have on top of a 350-m hill on Earth? It would have times more gravitational potential energy
Answer:
6
Explanation:
Just did it.
The gravitational potential energy would the same lander have on top of a 350-m hill on Earth is 6.
What is gravitational potential energy?If an object is lifted, work is done against gravitational force. The object gains energy.
The equation for calculating gravitational potential energy is
GPE =mgh
where, GPE is the gravitational potential energy, m is the mass, h is the change in height and g is the acceleration due to gravity.
The heavier the particle and the higher it is over the ground, the more gravitational potential energy it holds. Gravitational potential energy increments as weight and level increments.
Given is the height of hill h = 350m.
Thus, the same lander will have the the potential energy 6 times more.

A ball is thrown horizontally with an initial
velocity of 20 m/s from the top of a tower
60 m high. What is the initial vertical
velocity of the ball?
a. O m/s
b. 20 m/s
c. 3.5 m/s
d. 9.81 m/s
The initial vertical velocity of a ball thrown horizontally with an initial velocity of 20 m/s from the top of a 60 m high tower is 0 m/s (option a).
The ball is thrown horizontally, so its velocity will have only components in the x-direction (horizontal). The components of the initial velocity in the y-direction (vertical) will be zero.
For a ball's velocity to have components in the vertical and horizontal direction, the ball must be thrown at a certain angle to the ground, describing a parabolic movement.
In a parabolic movement, the vertical and horizontal components of the velocity would be:
[tex] v_{x} = v_{i}cos(\theta) [/tex]
[tex] v_{y} = v_{i}sin(\theta) [/tex]
Where:
[tex] v_{i} [/tex]: is the initial velocity
θ: is the angle
Therefore, the initial vertical velocity of the ball is zero (option a).

CUAL DE LAS SIGUIENTES LEYES NO PERTENECEN A LOS 3 PRINCIPIOS DE NEWTON? 1.LEY DE LA ATRACCION 2.LEY FUNDAMENTAL DE LA DINAMICA 3.LEY DE ACCION Y REACCION 4.LEY DE LA INERCIA
Answer:
La Ley de atracción no pertenece a los tres principios de Newton.
Explanation:
Las leyes de Newton son tres principios que sirven para describir el movimiento de los cuerpos, basados en un sistema de referencias inerciales (es aquél que está en reposo o se mueve con velocidad constante, es decir, no tiene aceleración).
Las 3 leyes de Newton son:
Primera Ley o Ley de Inercia : Esta ley enuncia que todo cuerpo permanece en su estado de reposo o de movimiento rectilíneo uniforme a menos que otros cuerpos actúen sobre él. Explica que para modificar el estado de movimiento de un cuerpo es necesario actuar sobre él. Segunda ley o Principio Fundamental de la Dinámica : Esta ley dice que la fuerza que actúa sobre un cuerpo es directamente proporcional a su aceleración. Es decir, si sobre un cuerpo actúa una fuerza, dicho cuerpo modificará su velocidad, es decir, adquirirá una aceleración. Dicha fuerza y su aceleración generada son proporcionales y están relacionadas mediante: F=m*a donde F es la fuerza aplicada, m es la masa del cuerpo sobre el que se aplica la fuerza y a es la aceleración adquirida por dicho cuerpo.Tercera ley o Principio de acción-reacción : Esta ley expresa que cuando un cuerpo ejerce una fuerza sobre otro, éste ejerce sobre el primero una fuerza igual y de sentido opuesto.Entonces, la Ley de atracción no pertenece a los tres principios de Newton.

Answer:
Explanation:
we know that
gravitational force(F)=Gm1m2/r^2
m1=25 kg
m2=0.55 kg
r=35 m
F=6.67*10^-11*25*0.55/35^2
F=0.075*10^-11
a 3000 kg and a 7000 kg Mass attract each other with a force of 0.0015 N. What distance separates the two objects (Radius) (Please Show Steps)
Answer:
3.057mExplanation:
According to law of gravitation;
F = GMm/d²
G is the universal gravitation
M and m are the masses
d is the distance between the masses
d² = GMm/F
d² = 6.67408 × 10-11 *3000*7000/0.0015
d² = 140.15568*10^-5/0.0015
d² = 1.4016*10^-3/0.0015
d² = 1.4016*10^-3/1.5*10^-3
d² = 0.9344*10
d² = 9.344
d = √9.344
d = 3.057m
Hence the distance between the two objects is 3.057m

Ceres is a large asteroid that orbits the Sun between Mars and Jupiter. Ceres has a mass of 9.4 x 1020 kg and a radius of about 4.7 x 10° m.
If a spacecraft attempts to land on the asteroid, what acceleration due to gravity will it experience near the surface?
Answer:
The acceleration due to gravity near the surface of Ceres is approximately 0.284 m/s²
Explanation:
The given parameters are;
The mass of Ceres = 9.4 × 10²⁰ kg
The radius of Ceres, r = 4.7 × 10⁶ m
By Newton's law of gravitation, we have;
[tex]Gravitational \ force\ on \ the \ spacecraft \ near \ Ceres, \ F =G\dfrac{m_{1}m_{2}}{r^{2}}[/tex]
Therefore;
[tex]Acceleration \ due \ to \ gravity \ g =G\dfrac{m_{1}}{r^{2}}[/tex]
Where;
m₁ = The mass of Ceres = 9.4 × 10²⁰ kg
m₂ = The mass of the spacecraft
G = 6.6743 × 10⁻¹¹ N·m²/kg²
Substituting the values, we get;
[tex]g \ near \ the \ surface \ of \ Ceres = \dfrac{ 6.6743 \times 10^{-11} \times 9.4 \times 10 ^{20}}{(4.7 \times 10^5)^{2}} \approx 0.284 \ m/s^2[/tex]
The acceleration due to gravity near the surface of Ceres ≈ 0.284 m/s²
