A force is acting on a 3-kg object during 5 seconds. If the object initially has a speed of 1.5m/s and after applying the force its speed is 4 m/s
Answer:
1.5 N
Explanation:
You've left us to guess what the question is. I will Assume it is what's the force?
Givens
m = 3 kg
vi = 1.5 m/s
vf = 4 m/s
t = 5 seconds
Formula
F = m * (vf - vi)/t
Solution
F = 3 * (4 - 1.5) / 5
F = 1.5 N

Use coefficients to balance the following chemical equation. Remember a balanced chemical equation has the same number of atoms of each element on each side of the equation. Hint: create a table on scratch paper to count your atoms on each side of the equation so_(g) + ___02(g) → _so, (g)
Answer: The given equation is balanced as [tex]SO_{2}(g) + O_{2}(g) \rightarrow SO_{3}(g)[/tex]
Explanation:
A chemical equation that contains same number of atoms on both reactant and product side are called balanced chemical equation.
For example, [tex]SO_{2}(g) + O_{2}(g) \rightarrow SO_{3}(g)[/tex]
Here, number of atoms on reactant side are as follows.
S = 1O = 4Number of atoms on product side are as follows.
S = 1O = 3To balance this equation, multiply [tex]SO_{2}[/tex] by 2 on reactant side and multiply [tex]SO_{3}[/tex] also by 2 on product side.
Hence, the equation will be rewritten as follows.
[tex]2SO_{2}(g) + O_{2}(g) \rightarrow 2SO_{3}(g)[/tex]
Here, number of atoms on reactant side are as follows.
S = 2O = 6Number of atoms on product side are as follows.
S = 2O = 6As there are same number of atoms on both reactant and product side. So, this equation is a balanced equation.
Thus, we can conclude that the given equation is balanced as [tex]SO_{2}(g) + O_{2}(g) \rightarrow SO_{3}(g)[/tex]
What is missing from the solubility graph shown on the right?
Answer:
the name and the units of the vertical axis. Explanation: As you see the horizontal axis shows that the independent variable is Temperature and that it is reported in °C.
Explanation:
Answer
The horizontal axis reveals to us that the independent variable is temperature which is reporting in C. We know that but what we dont know is the name or the untis on the vertical axis. Also a nice title and chart by it will help as well. A legend as well to explain what the colors even mean.

what effect does the earth's surface have on solar radiation?
A. The ground absorbs half the solar radiation and stored it as infrared radiation for centuries
B. Half of the solar radiation is absorbed and converted to infrared (heat)
C. Nearly all solar radiation is reflected back into space by the ground
Answer:
B.
Explanation:
Solar radiation that is not absorbed or reflected by the atmosphere (for example by clouds) reaches the surface of the Earth. The Earth absorbs most of the energy reaching its surface, a small fraction is reflected. In total approximately 70% of incoming radiation is absorbed by the atmosphere and the Earth’s surface while around 30% is reflected back to space and does not heat the surface. The Earth radiates energy at wavelengths much longer than the Sun because it is colder. Part of this longwave radiation is absorbed by greenhouse gases which then radiate energy into all directions, including downwards and thereby trapping heat in the atmosphere.
Hope this helps, sorry if it is incorrect. Have a great day/night!

What is solar radiation?Solar radiation, often called the solar resource or just sunlight, is a general term for the electromagnetic radiation emitted by the sun.
Solar radiation can be captured and turned into useful forms of energy, such as heat and electricity, using a variety of technologies

10. Observa la siguiente gráfica que describe un recorrido en línea recta de un caballo: a) ¿Qué tipo de movimiento presenta el caballo? Justifica la respuesta. b) Indica la distancia que ha recorrido el caballo a los tres segundos de empezar el recorrido. c) Calcula su velocidad media.
Answer:
Movimiento de translación.
Explicación:
El caballo tiene un tipo de movimiento traslacional porque todas las partes de su cuerpo se mueven de un lugar a otro. La distancia se puede encontrar usando la fórmula de distancia que es distancia = velocidad x tiempo. La velocidad promedio del caballo se puede calcular dividiendo la distancia total recorrida por el tiempo total tomado. Si los datos están disponibles, puede calcular la distancia y la velocidad promedio del caballo.

A motor-cycle rider going 90km/hr around a curve with a radius of 100m must lean at an angle to the vertical. The angle at which he leans is *
Answer:
The angle of inclination of the rider to the vertical is 32.5⁰.
Explanation:
Given;
linear speed of the motor cycle, v = 90 km/hr = 25 m/s
radius of the circle, r = 100 m
The angle of inclination of the rider to the vertical is calculated using banking angle formula;
[tex]\theta = tan^{-1}(\frac{v^2}{rg} )\\\\\theta = tan^{-1} (\frac{25^2}{100 \times 9.8} )\\\\\theta = 32.5 ^0[/tex]
Therefore, the angle of inclination of the rider to the vertical is 32.5⁰

Answer:
Explanation:
The radial velocity method involves watching the spectral lines of a star as a planet orbits the star. Because of the planets gravitational pull on the star, the star will wobble. This causes Doppler shifts in the spectral lines, allowing astronomers to infer the presence of the planets.

When matter changes shape, does its mass change?
Answer:
No, the mass of an object is always the same, even if a chemical reaction happens or the object becomes denser.
Explanation:
A sled slides down a hill with friction between the sled and hill but negligible alr resistance. Which of the following must be correct about the resulting change in energy of the sled Earth system?
A) The sum of the kinetic energy and the gravitational potential energy changes by an amount equal to the energy dissipated by friction,
B)The gravitational potential energy decreases and the kinetic energy is constant.
C)The decrease in the gravitational potential energy is equal to the increase in kinetic energy
D)The gravitational potential energy and the kinetic energy must both decrease.
Answer:
A) The sum of the kinetic energy and the gravitational potential energy changes by an amount equal to the energy dissipated by friction,
Explanation:
The kinetic energy is the energy that the object has and is defied by the work that is needed to accelerate the body. The gravitational potential is a mechanism by which an equal amount of energy is being transferred per unit mass that is needed for the object to move from the specific location.Hence when the sled moves down the hill with the force of gravity it has negligible resistance as an equal amount of energy is dissipated.The sum of the kinetic energy and the gravitational potential energy changes by an amount equal to the energy dissipated by friction.
What is principle of conservation of energy?The principle of conservation of energy states that, the total mechanical energy of an isolated system is always conserved.

Pls answer
Answer:
Explanation:
Lift occurs when a moving flow of gas is turned by a solid object. The flow is turned in one direction, and the lift is generated in the opposite direction, according to Newton's Third Law of action and reaction. Because air is a gas and the molecules are free to move about, any solid surface can deflect a flow.
