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?
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?
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.

Which of the following is not true about both scientific laws and scientific theories?
Answer:
In general, a scientific law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. The explanation of a phenomenon is called a scientific theory. It is a misconception that theories turn into laws with enough research
Explanation:
I need help with question ii) Calculate the speed of these radio waves.
I don't know if I started it right.... I need help plss!!!
Answer:
Speed = Wavelength x Wave Frequency. In this equation, wavelength is measured in meters and frequency is measured in hertz (Hz), or number of waves per second. Therefore, wave speed is given in meters per second, which is the SI unit for speed.

A glass rod is rubbed briefly with silk and the rod becomes able to attract and lift a number of small pieces of paper. If the rod is rubbed with silk for a longer period of time, explain what will happen and why.
QUICKLY PLEASE!
Answer:
it will have a stronger attraction force
Explanation:
If the rod is rubbed with silk for a longer period of time, then it attract large number of small pieces of paper.
When A glass rod is rubbed briefly with silk, then glass rod is heated because of rod become positively charged. That positively charged glass rod attracts the uncharged pieces of paper because some of the electrons present in the paper accumulate at the end near the rod.Learn more:

what are two roles of bacteria in a nitrogen cycle
Answer:Nitrogen-fixing bacteria convert free nitrogen gas into nitrogen compounds. ... Bacterias that are decomposers recycle nitrogen compounds in the soil by breaking down animal wastes and dead plants and animals. 3. Other bacteria break down nitrogen compounds and release free nitrogen back into the air.
Explanation:
"The nitrogen fixing and bacteria of decay" is the two major role of bacteria in nitrogen cycle."
What is nitrogen fixing?Nitrogen fixing can be define as the process in which It is possible to see nitrogen converting to nitrate.
What is bacteria of decay?Bacteria of decay can be define as the process in which it is possible to see nitrogen waste converting to ammonia.
What is nitrogen?Nitrogen can be referred as element which is kept in boron family in the periodic table.
Therefore, the two role of bacteria in a nitrogen cycle is bacteria of decay and nitrogen fixing.

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.
Adding Minutes to different types of soda and recording/comparing the reaction height is an example of a valid experiment.

If this is true, where does the mechanical energy go when skateboarding? Eventually the skateboarder will slow down and stop if she doesn't add more mechanical energy by pushing. Choose the most correct statement below.
Energy isn't conserved and actually gets used up.
Mechanical Energy converts into potential energy and then she stops.
Mechanical Energy gets converted into thermal energy through friction.
explain your answer
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.

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.
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.
