Explanation:
Hey there!
Given;
F = 10N
Mass = 5kg
Acceleration due to gravity (a)= 9.8m/s^2
We know that;
F = m*a
Put all values and solve for "m".
10 = m*9.8
Simplify it.
[tex]m = \frac{10}{9.8} [/tex]
Therefore, m= 1.0204kg.

Explain how conduction, convection, and radiation drive the water cycle in Earth’s system.
Answer:
During the day, sunlight heats the ground, which in turn heats the air directly above it via conduction. At night, the ground cools and the heat flows from the warmer air directly above to the cooler ground via conduction.
Explanation:
Luck For You!
The process, in which conduction, convection, and radiation drive the water cycle in Earth’s system, is discussed in the answer.
What is water cycle?The energy from the sun is what largely drives the water cycle. By evaporating water from the oceans, lakes, rivers, and even the soil, this solar energy powers the cycle. Through the process of transpiration, more water is transferred from plants to the atmosphere. Water droplets gradually acquire enough mass to fall back to Earth as precipitation as liquid water evaporates or transpires, forming clouds and water vapour.
The precipitation eventually transforms into runoff or groundwater and makes its way back into the surface reservoirs across a variety of periods. The hydrosphere currently contains the same amount of water as it has always contained in the Earth system since the water cycle is essentially a closed system.
Solar heat energy comes on earth's surface via radiation to the ponds, lakes, oceans, seas, rivers and other water resources and then the waterbodies get heated via conduction and evaporation happens. During evaporation time temperature water vapor goes to high altitude via convection of heat and cloud forms.

A soccer player applies a force of 48.4 N to a soccer ball while kicking it. If the ball has
a mass of 0.44 kg, what is the acceleration of the soccer ball?
A. 27.3 m/s2
B. 21.3 m/s2
C. 110 m/s2
D. 104 m/s2
Answer:
C. 110 m/s2
Explanation:
Force = Mass x Acceleration
Since we have the force and the mass, we can rearrange this equation to solve for acceleration by dividing both sides by mass:
Force/Mass = (Mass x Acceleration)/Mass
Acceleration = Force/Mass
Now we just have to plug in our values and calculate!
Acceleration = 48.4/0.44
Acceleration = 110m/s/s
It is option C. 110 m/s2

– Un automóvil A viaja hacia el este a 80 Km/h, mientras que un segundo automóvil B viaja en la misma carretera a 70 Km/h. Determine la velocidad del automóvil B medida desde el automóvil A si: a) Viajan en sentido contrario acercándose uno al otro. B) Viajan en el mismo sentido.
Answer:
la respuesta esta abajo
Explanation:
La velocidad de un objeto A relativa a otro objeto B es la velocidad que el objeto A parecería tener para un observador que se mueve con B.
a) La velocidad relativa de dos cuerpos que se mueven en la dirección opuesta es la suma de su velocidad. Por lo tanto:
Velocidad relativa = 80 + 70 = 150 km / h
b) La velocidad relativa de dos cuerpos que se mueven en la misma dirección es la diferencia entre su velocidad. Por lo tanto:
Velocidad relativa = 80 - 70 = 10 km / h

True or False. Energy can move in waves.
True, energy can in move in waves because waves transfers energy during their propagations.
A wave is a disturbance that transfers energy from one point to another, along its path of propagation.
A wave can be mechanical or electromagnetic.
A mechanical type of wave requires material medium for its propagation.
Examples;

How long would it take Jesse with an acceleration of -2.50 m/s2 to bring his bicycle with an initial velocity of 13.5 m/s to a complete stop?
Answer: 5.4 seconds
Explanation:
The time taken to stop the bicycle is 5.4 seconds. The final velocity is zero. Then, the distance travelled by the bicycle is 36.45 m.
What is acceleration ?Acceleration is a physical quantity that, measures the rate of change in velocity. It is a vector quantity thus having both magnitude and direction. It can be defines as the ratio of change in velocity to the change in time.
Given initial velocity = 13.5 m/s
final velocity is zero since the bicycle is stopping.
then Δt = Δv/a
Δt = 13.5 m/s/ 2.50 m/s² = 5.4 seconds.
Hence, the bicycle will take 5.4 s to complete stop.
The distance covered within this time can be determined using the equation as follows:
s = ut + 1/2 at²
where u is the initial velocity
s = (13 m/s × 5.4 s) + (-2.50 m/s² ×5.4 s ×5.4 s) = 36.4 m.
Therefore, the bicycle will travel up to 36.4 m before stopping.

Explanation:
Emma has a large piece of taffy (1.5 kg) that she wants to share with her friend Camila. However, Emma is having a hard time breaking the piece by herself. So, Emma grabs one end of the taffy while Camila grabs the other end. They both pull on the taffy in opposite directions: Emma pulls with 20 N and Camila with 23 N. Calculate the acceleration and give the direction of the acceleration.
Answer:
The acceleration is 2 m/s² in Camila's direction.
Explanation:
The acceleration can be found using the following equation:
[tex] \Sigma F = ma [/tex]
Where
F is the force
m is the mass of the taffy = 1.5 kg
a is the acceleration =?
Since Emma pulls one end of the taffy with 20 N and Camila pulls the other end with 23 N we have:
[tex] F_{C} - F_{E} = ma [/tex]
[tex]23 N - 20 N = 1.5 kg*a [/tex]
[tex] a = 2 m/s^{2} [/tex]
Hence, the acceleration is 2 m/s² in Camila's direction.

The force (applied) with which it was hit, F = 50 N
The acceleration, a = Force/Mass = 50 N/(15 kg) = 10/3 = 3.[tex]\overline 3[/tex] m/s²
The acceleration = 3.[tex]\overline 3[/tex] m/s²
Problem 3 -
The mass of the object, m = 2.0 kg
The force (applied) with which it was hit, F = 5.0 N
The acceleration, a = Force/Mass = 5.0 N/(2.0 kg) = 2.5 m/s²
The acceleration = 2.5 m/s²
Problem 4-
The mass of the object, m = 3.0 kg
The acceleration, a, of the object = 2.5 m/s²
The force applied to it, F = Mass × Acceleration = 3.0 kg × 2.5 m/s² = 7.5 N
The force applied = 7.5 N
Problem 5-
The acceleration, a, of the object = 12 m/s²
The force applied, F = 6.0 N
The mass of the object, m = Force/Acceleration = 6.0 N/(12 m/s²) = 0.5 kg
The mass of the object, = 0.5 kg.

For a hypothesis to become generally accepted by scientists, It must have been tested by many scientists. Hence option B is correct.
What is hypothesis ?A hypothesis is a theory put up to explain a phenomena. A hypothesis must be testable according to the scientific method for it to be considered a scientific hypothesis. Scientific hypotheses are often based on prior findings that cannot be adequately explained by the current body of knowledge. Despite the fact that the terms "hypothesis" and "theory" are sometimes used interchangeably, they are not the same thing. A working hypothesis is an acknowledged theory that has been tentatively supported and is put up for further investigation.

For his science project, Austin wants to determine if the pH of standing rainwater changes over time. He collects rainwater and distributes it evenly in 5 jars and places them all indoors in a spot that does not receive a lot of sunlight to limit evaporation. Using a pH testing kit, he measures the pH of the water in the first jar on the 4th day, second jar on the 8th day, third jar on the 12th day, fourth jar on the 16th day and fifth jar on the 20th day. What is the independent, or manipulated, variable in Austin's experiment?
Answer:
This question lacks options, the options are:
A. the number of days the rainwater was allowed to sit
B. the number of times the rainwater was observed
C. the change in the amount of rainwater due to evaporation
D. the change in pH of the rainwater over time
The answer is A
Explanation:
In an experiment, the independent variable is the variable that is changed or manipulated by the experimenter in order to effect a measurable response.
In this experiment, Austin is trying to determine how time changes the pH of standing rainwater. He collects rainwater and distributes it evenly in 5 jars, which he measured the pH at different days using a pH testing kit. Hence, the independent or manipulated variable is THE NUMBER OF DAYS THE RAINWATER WAS ALLOWED TO SIT before measuring their pH.
