Given the force exerted on the object with the given mass, the acceleration of the object is 5m/s².
Given the data in the question;
Mass; [tex]m = 2.0kg[/tex]Net Force; [tex]F = 10.0N[/tex]Acceleration; [tex]a =\ ?[/tex]
To determine the acceleration of the mass, we use Newton Second Law of Motion:
[tex]F = m * a[/tex]
Where m is mass of the object and a is the acceleration.
We substitute our given values into the equation and solve for "a"
[tex]10.0N = 2.0kg * a\\\\10.0kg.m/s^2 = 2.0kg * a\\\\a = \frac{ 10.0kg.m/s^2}{2.0kg}\\\\a = 5m/s^2[/tex]
Therefore, given the force exerted on the object with the given mass, the acceleration of the object is 5m/s².

How are both chemistry and physics related to geoscience?
Answer:
Earth science or geoscience includes all fields of natural science related to the planet Earth. This is a branch of science dealing with the physical and chemical constitution of the Earth and its atmosphere. Earth science can be considered to be a branch of planetary science, but with a much older history. Earth science encompasses four main branches of study, the lithosphere, the hydrosphere, the atmosphere, and the biosphere, each of which is further broken down into more specialized fields.
There are both reductionist and holistic approaches to Earth sciences. It is also the study of Earth and its neighbors in space. Some Earth scientists use their knowledge of the planet to locate and develop energy and mineral resources. Others study the impact of human activity on Earth's environment, and design methods to protect the planet. Some use their knowledge about earth processes such as volcanoes, earthquakes, and hurricanes to plan communities that will not expose people to these dangerous events.
The Earth sciences can include the study of geology, the lithosphere, and the large-scale structure of the Earth's interior, as well as the atmosphere, hydrosphere, and biosphere. Typically, Earth scientists use tools from geology, chronology, physics, chemistry, geography, biology, and mathematics to build a quantitative understanding of how the Earth works and evolves. Earth science affects our everyday lives. For example, meteorologists study the weather and watch for dangerous storms. Hydrologists study water and warn of floods. Seismologists study earthquakes and try to understand where they will strike. Geologists study rocks and help to locate useful minerals. Earth scientists often work in the field—perhaps climbing mountains, exploring the seabed, crawling through caves, or wading in swamps. They measure and collect samples (such as rocks or river water), then they record their findings on charts and maps.

Free Fall Practice Problems
1. A baseball is popped straight up in the air at a velocity of 42.0 m/s.
What time does it spend in the air before reaching the same
elevation from which it was popped up?
2. A golf ball is dropped from a cliff and strikes the ground with a
downward velocity of 34.0 m/s. How high is the cliff?
3. An air rocket is launched straight upwards at 27.0 m/s. What is its
velocity at time t=4.80 s?
4. A giant lizard jumps straight upwards from the ground at 4.30 m/s.
To what height does the lizard rise before going back down again?
5. A person falls from a bridge that is 18.0 m above the water. What
is the velocity of impact with the water?
Answer:
(1) t = 4.29 s
(2) h = 58.98 m
(3) v = 20.04 m/s (downward)
(4) h = 0.94 m
(5) v = 18.78 m/s
Explanation:
Assumption:
during downward motion, acceleration due to gravity, g is positive. (+g)during upward motion, acceleration due to gravity, g is negative. (-g)(1)
initial velocity of the baseball, u = 42.0 m/s
final velocity of the ball, v = 0
time of flight is given by;
v = u -gt
gt = u
t = u / g
t = 42 /9.8
t = 4.29 s
(2)
Given;
initial velocity of the golf, u = 0
final velocity of the golf, v = 34 m/s
the height of the cliff is given by;
v² = u² + 2gh
v² = 0 + 2gh
h = v²/2g
h = (34)²/(2x9.8)
h = 58.98 m
(3)
Given;
initial velocity of the rocket, u = 27 m/s
time of motion, t = 4.8s
final velocity, v = ?
v = u + gt
v = 27 + (-9.8 x 4.8)
v = 27 - 47.04
v = -20.04 m/s (the negative sign indicates downward motion of the rocket after 4.8 s)
(4)
Given;
initial velocity of the lizard, u = 4.3 m/s
final velocity of the lizard at maximum height, v = 0
the height rose by the lizard is given by;
v² = u² + 2(-g)h
0 = u² - 2gh
2gh = u²
h = u² / 2g
h = (4.3)²/(2 x 9.8)
h = 0.94 m
(5)
Given;
initial velocity of the person on the bridge, u = 0
height of the bridge, h = 18 m
final velocity of the person is the velocity at impact, v = ?
v² = u² + 2gh
v² = 0 + 2gh
v² = 2gh
v = √2gh
v = √(2 x 9.8 x 18)
v = 18.78 m/s

Answer:
-10C= Solid
10C= Liquid
50C= Liquid
90C= Liquid
110C= Gas
120C= Gas
Explanation:
Below 0 degree C (Celsius), water is frozen means it is in the form of ice. After 0 degree, once we keep it in room temperature, the ice starts becoming liquid (water), and once we heat water, after 100 degree C (Celsius) water starts boiling and thus starts entering gaseous state.
A 450.0 kg boat experiences two simultaneous forces. The motor exerts a force of 100.0 N to accelerate the boat forward, while an unknown drag force pushes in the opposite direction. The boat accelerates forward at 0.1330 m/s2. Calculate the drag force acting on the boat.
Answer:
The drag force is [tex]D = 40.15 \ N[/tex]
Explanation:
From the question we are told that
The mass is [tex]m = 450.0 \ kg[/tex]
The acceleration [tex]a = 0.133 m/s^2[/tex]
The force due to the motor is [tex]F_m = 100 \ N[/tex]
Generally the net force acting on the boat is mathematically represented as
[tex]F = m * a[/tex]
=> [tex]F = 450.0 * 0.1330[/tex]
=> [tex]F = 59.85 \ N[/tex]
Generally the drag force acting on the boat is mathematically represented as
[tex]D = F_m -F[/tex]
=> [tex]D = 100 - 59.85[/tex]
=> [tex]D = 40.15 \ N[/tex]

Which of the following graphs best shows the velocity v of the clay ball from when it is dropped until it hits the ground?
Answer:
The correct option is;
C
Explanation:
The given information is that a clay ball is dropped from a certain height.
Therefore, the clay ball has an initial potential energy and zero kinetic energy
Which gives that the initial velocity of the clay ball = 0
As the potential energy is converted into kinetic energy, the velocity of the clay ball increases
However, if the direction of measurement of the velocity is opposite to the direction in which the clay ball is falling, the velocity of the ball progressively increases negatively as shown in option C

Which of the following reactions best illustrates the Law of Conservation of Mass?
A. H2O2 → H2O + O2
B. Na + CuS → Na2S + 2 Cu
C. K + AgCl → KCl + Ag
D. NaOH + 2 HCl → NaCl + H2O
Answer:
A
Explanation:
Mass does not change no matter what!!! In this instence it is all still there. hope it helps
In the reaction, K + AgCl → KCl + Ag, the masses are constant before and after the reaction. Hence, this illustrates the Law of Conservation of Mass. So, option (C) is correct.
The given problem is based on the chemical analysis for the law of conservation of mass. As per the law of conservation of mass, "In a chemical reaction, the mass of reactant can neither be created, nor be destroyed. But it can change its phase".
In the chemical reaction,
K + AgCl → KCl + Ag
Clearly in the potassium and silver chloride, the mass of reactant (potassium and silver chloride) remains same (or constant) while forming a product (potassium chloride and Silver). Which is not observed in other given chemical reactions.
Thus, we can conclude that in the reaction, K + AgCl → KCl + Ag, the masses are constant before and after the reaction. Hence, this illustrates the Law of Conservation of Mass. So, option (C) is correct.

A progressive wave equation is represented by y=Asin 2π(0.15t-0.1x). find the period
Answer:
y=Asin 2π(0.15t-0.1x)
At some time t and coordinate x let (0.15t-0.1x) = n where n is an integer.
y will be zero
At a later time and the same value of x
(0.15(t + P)-0.1x) = n +1 where P is the period ; y again will be zero
(0.15(t + P)-0.1x) = n +1
(0.15t-0.1x) = n
.015 P = 1 subtracting equations
P = 1 / .15 = 6.67 sec
laws of solid friction
Answer: When an object is moving, the friction is proportional and perpendicular to the normal force (N)
Friction is independent of the area of contact so long as there is an area of contact.
The coefficient of static friction is slightly greater than the coefficient of kinetic friction.
Within rather large limits, kinetic friction is independent of velocity.
Friction depends upon the nature of the surfaces in contact.

If the mass of block B is 2kg, the gravitational force exerted on block B is most nearly which of the following?
0.2N
2N
20N
P.S The acceleration is 10m/s^2 but I have no idea how to get that, so could someone explain that to me.
Answer:
20 N.
Explanation:
The following data were obtained from the question:
Mass of block B (m) = 2 Kg
Acceleration due to gravity (g) = 10 m/s²
Gravitational force (F) =..?
Force is simply defined as the product of mass and acceleration i.e
Force = mass (m) × acceleration (a)
F = ma
Thus, we can say that the gravitational force on block B will be the product of the mass of block B and acceleration due to gravity i.e
Gravitational force (F) = mass of block B (m) × acceleration due to gravity (g)
F = mg
Mass of block B (m) = 2 Kg
Acceleration due to gravity (g) = 10 m/s²
Gravitational force (F) =..?
F = mg
F = 2 × 10
F = 20 N
The, the gravitational force exerted on block B is 20 N
Gravitational force exerted on block B is 20 N
Given that;
Mass of block = 2 kg
Acceleration = 10 m/s²
Find:
Gravitational force exerted on block B
Computation:
Gravitational force = ma
Gravitational force exerted on block B = Mass of block × Acceleration
Gravitational force exerted on block B = 2 × 10
Gravitational force exerted on block B = 20 N
