A rope exerts a 35N force on an object at an angle of 12N degrees above the horizontal. What horizontal and vertical components of the force?
Answer:
The horizontal component of the force, [tex]F_x= 34.24 \ N[/tex]
The vertical component of the force, [tex]F_y=7.28 \ N[/tex]
Explanation:
Given;
Force on the rope, F = 35 N
angle between the rope and the horizontal = 12 °
The horizontal component of the force is given by;
[tex]F_x = Fcos \theta\\\\F_x = 35cos(12^0)\\\\F_x = 34.24 \ N[/tex]
The vertical component of the force is given by;

A student puts a beaker of boiling water where it touches a block of ice. Which two statements are true? A. Thermal energy will move from the boiling water to the ice. B. Thermal energy will move from the air to the ice. O C. Thermal energy will move from the ice to the air D. Thermal energy will move from the air to the boiling water.
A student puts a beaker of boiling water where it touches a block of ice. The two true statements are that the thermal energy will move from the boiling water to the ice and the thermal energy will move from the air to the ice. Therefore the correct options are options A and option B.
What is the boiling point?
It is a temperature at which the pressure exerted by the external atmosphere is equal to the vapor pressure of the substance.
The boiling point depends on atmospheric pressure, temperature, bond strength, and vapor pressure of the liquid.
As the water is boiling it means it has more thermal energy contained in it than the surrounding air and the ice is present at zero degrees.
As we know that heat is always transferred from the higher thermal potential to the lower thermal potential and as the boiling water has the higher thermal potential among the ice and the surrounding air thermal energy will move from the boiling water to the ice and the thermal energy will move from the air to the ice. Therefore the correct options are options A and option B.

2 kg of water and 2 kg of Copper are cooled from same temperature to the same temperature. Why does the water cool more slowly than the Copper?
Answer:
Water has higher specific heat capacity compared to copper. This means that water needs to absorb more heat energy to increase it's temperature by 1 °C. Therefore, water needs longer time to release heat energy due to higher amount of heat energy stored inside the water.

Which is a valid velocity reading for an object?
Answer:
45 m / s North is a valid vector reading for an object.
Explanation:
Then velocity will be defined by x km / hr North. And, magnitude of velocity defines the speed of the body. Although this tells the speed, but there is no description for the direction, so it's not a vector reading
45 m/s north is a valid velocity reading for an object. So, the correct option is B.
What is Velocity?Velocity is explained as displacement in a given amount of time which is a vector quantity, meaning it has both magnitude and direction. When a body travelling on a straight path at a speed of x km / hr in North, then the velocity will be defined by x km / hr North.
Options like 45m/s, 0 m/s north and 0 m/s are speed, null velocity and speed respectively, as it tells speed, but no description for direction, so it is not a vector reading. 45 m / s North tells about the speed as well as its direction and the magnitude of velocity.
Thus, 45 m/s north is a valid velocity reading for an object. So, the correct option is B.

Consciousness is still a controversial issue among psychologists and philosophers is a true statement.
What is Consciousness?You experience everything as consciousness. It is the song that keeps playing in your head, the sweetness of chocolate mousse, the agonizing pain of a toothache, the passionate love you have for your child, and the painful realization that these emotions eventually pass.
From the earliest ages of antiquity till the present, the origin and nature of these experiences, also referred to as qualia, have remained a mystery.
Many contemporary analytic philosophers of mind, probably most notably Daniel Dennett of Tufts University, claim that consciousness is an illusion because they find it to be such an awful affront to what they feel should be a meaningless cosmos of matter and the void.
Therefore, Consciousness is still a controversial issue among psychologists and philosophers is a true statement.

Explanation:
A wooden block is pulled at a constant acceleration of 1.4 m/s2. Find the net applied force on the block if its mass is 0.6 kg.
Answer:
F = 0.84 [N]
Explanation:
In order to solve this problem we must take into account Newton's second law, which tells us that the sum of all forces applied on a body must be equal to the product of the mass of the body by its acceleration.
F = m*a
where:
F = force [N]
a = acceleration = 1.4[m/s^2]
m = mass = 0.6 [kg]
F = 0.6*1.4
F = 0.84 [N]
Why salt is a pure substance and salt solution is considered to be a mixture
Explanation:
Salt (NaCl) is a pure substance because it contains two elements in a fixed ratio and has only one component. On the other hand, salt solution is a mixture, as it has two different components- salt and water.*IT MAY HELP U.Plz marke as a brainlist
Answer:
Mixtures are defined as assemblies of materials that have no chemical bonds between them and thus can usually be separated - like sand and water.
Solutions where a solid material such as salt is completely dissolved are not generally thought of as mixtures because there is loose hydrogen bonding involved in the dissolving of a solute in a solvent.
Solutions lie between pure substances and true mixtures, but are usually not thought of as mixtures.

how to explain horizontal in words
In astronomy and geography, a direction or plane is said to be horizontal if it is perpendicular to the vertical direction. In mathematics, anything parallel to the horizon is called horizontal. Because vertical is the opposite of horizontal, anything that makes a 90-degree angle (right angle) with the horizontal or the horizon is called vertical. So, the horizontal line is one that runs across from left to right.

Two identical stones are simultaneously launched horizontally from two slingshots at
the same height. Stone A is launched with an initial speed of 5 m/s. Stone B is
launched with an initial speed of 1 m/s. Which stone hits the ground first, and where
do they land?)
Answer:
a) Both stones hit at the same time, b) Stones A and B will land at a distance of [tex]2.26\sqrt{y_{o}}[/tex] and [tex]0.452\sqrt{y_{o}}[/tex] meters, respectively.
Explanation:
Each stone experiments a parabolic motion, that is, the combination of a horizontal motion at constant velocity and a vertical uniform accelerated motion due to gravity. We know that each stone is launched horizontally at the same height and from the same initial position.
The equations of motion for each stone are described below:
Stone A
[tex]x_{A} = x_{o} + v_{A,o}\cdot t_{A}[/tex]
[tex]0 = y_{o} + \frac{1}{2}\cdot g\cdot t_{A}^{2}[/tex]
Stone B
[tex]x_{B} = x_{o} + v_{B,o}\cdot t_{B}[/tex]
[tex]0 = y_{o} + \frac{1}{2}\cdot g\cdot t_{B}^{2}[/tex]
a) Which stone hits the ground first?
The stone that hits the ground first has the lowest time. If we know that [tex]v_{A,o} = 5\,\frac{m}{s}[/tex], [tex]v_{B,o} = 1\,\frac{m}{s}[/tex], [tex]x_{o} = 0\,m[/tex] and [tex]g = -9.807\,\frac{m}{s^{2}}[/tex], then the equations of motion are reduced into this:
Stone A
[tex]x_{A} = 5\cdot t_{A}[/tex] (Eq. 1)
[tex]y_{o} -4.905\cdot t_{A}^{2}= 0[/tex] (Eq. 2)
Stone B
[tex]x_{B} = t_{B}[/tex] (Eq. 3)
[tex]y_{o} -4.905\cdot t_{B}^{2}= 0[/tex] (Eq. 4)
From (Eq. 2) and (Eq. 4), we get that [tex]t_{A} = t_{B}[/tex].
Both stones hit at the same time.
b) Where do they land?
From (Eq. 2) and (Eq. 4), we get:
[tex]y_{o} = 4.905\cdot t^{2}[/tex]
The time is cleared within the expression:
[tex]t =\sqrt{\frac{y_{o}}{4.905} }[/tex]
[tex]t \approx 0.452\sqrt{y_{o}}[/tex]
And from (Eq. 1) and (Eq. 3), we get the following equations of motion:
[tex]x_{A}= 5\cdot t[/tex]
[tex]x_{B} = t[/tex]
The horizontal distance taken by each stone is calculated by direct substitution on each expression:
[tex]x_{A} = 2.26\sqrt{y_{o}}\,m[/tex]
[tex]x_{B} = 0.452\sqrt{y_{o}}\,m[/tex]
Stones A and B will land at a distance of [tex]2.26\sqrt{y_{o}}[/tex] and [tex]0.452\sqrt{y_{o}}[/tex] meters, respectively.
