I'd like some help in these two questions please, thankyou so much. have a great day! stay safe and stay happy. (there are two parts of one question so uh yea.
Answers
Answer:
The resultant force is 25 N in the negative x-direction.
Explanation:
We need to find the total force in the x and y-direction and then the resultant force will be the magnitude of the sum of Fx and Fy.
Total force in the x-direction:
[tex]F_{x}=12-37=-25\: N[/tex]
Total force in the y-direction:
[tex]F_{y}=10-10=0\: N[/tex]
Therefore, the magnitude of the resultant force will be:
[tex]F_{R}=\sqrt{F_{x}^{2}+F_{y}^{2}}[/tex]
[tex]F_{R}=\sqrt{(-25)^{2}+0}[/tex]
[tex]|F_{R}|=25\: N[/tex]
The resultant force is 25 N in the negative x-direction, in other words, the car will move to the left.
I hope it helps you!

Asking your friends what kind of candy they like and recording the responses.
recording answers are a valid experiment. but at the same time adding minutes to different types of soda and recording is another great idea.
Statement A is correct. Adding Minutes to different types of soda and recording/comparing the reaction height is an example of a valid experiment.
What is an experiment?An experiment is a technique used to prove or disprove a theory, or to test the efficacy or probability of something that has never been done before.
Experiments reveal cause-and-effect relationships by illustrating what happens when a specific component is changed. Experiments have a wide range of goals and scales,
but they always rely on a repeatable technique and rational interpretation of the outcomes. Natural experimental research is also available.

B. During interference, the wave will produce a louder sound.
C. The amplitude of the wave is decreased.
D. The crests of two waves are overlapping.
E. The troughs of the two waves are overlapping.
There is more than one answer. Help plz
Answers
The statement i.e. true with respect to the constructive interference diagram should be that the two waves should be overlapped.
What is the constructive interference?At the time when two waves of the same kind of wavelength should be in phase so they created the new wave along with the amplitude that should be equivalent to the sum of the inidvidual amplitudes so this we called as the constructive interference
As per the given diagram, we can say that the crest for two waves that should be overlapped should be considered.

Answer: Mechanical Energy gets converted into thermal energy through friction
Explanation: when the skateboard is rubbing against whatever it’s rolling on it creates friction which slows down the skateboard, the mechanical energy is then converted into thermal energy. If you’ve ever touched the bottom of a wheel after going fast it typically feels a little warm.

If the crests of two waves overlap, which of the following will be true regarding the new wave formed?
A. The new wave will produce a lower-pitched sound than the two original waves.
B. The new wave will produce a louder sound than the two original waves.
C. The new wave will produce a quieter sound than the two original waves.
D. The new wave will produce a higher-pitched sound than the two original waves.
Answers
Answer:
c
Explanation:
Answer: b
Explanation: Constructive Interference – when waves combine to form a wave with a larger amplitude. They add their energies, so when the crests of two waves overlap, they make a higher crest. If two troughs overlap, they make a deeper trough.

1.Gravity is an invisible force that pulls objects toward each other
2.The suns gravity pulls the planet towards the sun which changes the straight line of direction into a curve

1. Gravity is an imperceptible force that pulls entities toward each other
2. When The sun's gravity pulls the planet towards.
What is Gravity?
The gravitational attraction of the original gaseous significance present in the Universe forced it to begin coalescing and creating stars and caused the stars to group concurrently into galaxies,
So, gravity is accountable for the consideration of the large-scale structures in the Macrocosm.
When the sun transforms the straight line of movement into a curve That preserves the planet pushing in an orbit almost like the sun.
The gravity pulls the sun and the planets concurrently while controlling them apart. The inertia feeds the tendency to preserve speed and keep pushing.
Nevertheless, the gravitational pull desires to reverse the motion to pull the planets into the core of the sun.

An model leans off a bridge railing to take a picture and accidentally drops their phone. The phone's mass is 0.115 kg and the bridge is 15 m tall. The instant the model dropped the phone, it's mechanical energy is 16.9 joules? why?
Answers
Answer:
The statement is true:
Explanation:
As said in the statement, we need to measure the mechanical energy(M.E) of the phone at the instant is dropped:
M.E = P.E + K.E
Given the fall hasn't yet begun, the kinetic energy (K.E) is equal to zero so M.E = P.E
We must use the Potential Energy formula :
P.E = h x m x g
We know that g is equal to 9.8 [tex]J.kg^{-1} .m^{-1}[/tex] on Earth, the height is 15m and m is 0.115:
M.E = 15 x 0.115 x 9.8 = 16.9 Joules

What are the characteristics of bones? (list 7)
What role do joints play?
What are the two types of joints?
What are ligaments?
Answers
Answer:
1) The human skeleton performs six major functions: support, movement, protection, production of blood cells, storage of minerals, and endocrine regulation. protection of internal organs
2) Joints are where two bones meet. They make the skeleton flexible — without them, movement would be impossible. Joints allow our bodies to move in many ways.
3)A joint is a point where two or more bones meet. There are three main types of joints; Fibrous (immovable), Cartilaginous (partially moveable) and the Synovial (freely moveable) joint
4)A ligament is a fibrous connective tissue which attaches bone to bone, and usually serves to hold structures together and keep them stable.
Explanation:
go-gle your welcome ;)
They are lightweight yet strong and hard, and serve multiple functions. Bone tissue (osseous tissue) is a hard tissue, a type of specialized connective tissue. It has a honeycomb-like matrix internally, which helps to give the bone rigidity. Bone tissue is made up of different types of bone cells.
2) Joints are functional junctions between two or more bones. Joints bind the skeleton together, to give structure and allow muscles to move bones to perform certain tasks such as running, reaching and grasping. There are many types of joints the most common of which are synovial joints

Give three examples of properties of elements
Answers
Answer: Atomic number, Atomic Mass, Ionic radius
Explanation:
The three examples of properties of elements are Atomic Number, Melting Point, and Electronegativity are the properties of the element.
Atomic Number: The atomic number of an element is the number of protons found in the nucleus of an atom of that element. Each element has a unique atomic number.
Melting Point: The melting point of an element is the temperature at which it transitions from a solid state to a liquid state. Different elements have different melting points, which can vary widely.
Electronegativity: Electronegativity is a measure of an element's ability to attract electrons toward itself in a chemical bond. It is an important property in determining the nature of chemical bonding and the reactivity of elements. Elements with high electronegativity tend to attract electrons strongly.
Other properties include atomic mass, density, boiling point, reactivity, and many more, which contribute to the diverse behavior and characteristics of elements in the periodic table.
