It goes around the x axis
Answer:
a = αR
Then We apply the Newton's second law of motion:
∑ F = ma
F - mg sinθ - f = ma.
F - mg sinθ - μmg cosθ = ma
Using given data we have:
F - 3217 = 470a ........................... (1)
Apply the Newton's law for rotation:
∑τ = I α
FR - (mg sinθ)R = 
then: F - mg sinθ = 3ma / 2.
F - 2774 = 705a .......................... (2)
solving 1 and 2 we get:
F = 4103 N
a = 1.885 m/s²
b) In this case the time is given by:
t = 
it comes from: d = 
starting from rest vo = 0
t = 
= 3.09 s
The astrometric technique of planet detection works best for massive planets around nearby stars.
Essay on the problems kenge will face going to college in the story seeing is believing is described below
Explanation:
1.An essay is really just a body of words meant to convey something. So, in your class, you used an essay to convey the pros and cons of love
2.In the admissions essays, you are using an essay to convey something about yourself. You will probably be asked to write about the reasons you want to enter a specific field or college, an event in your life that helped shape you, or other personal subjects. If it helps, rewrite these prompts into questions:
REAL examples
- Why do you want to go to Harvard?
- Why do you want to enter the medical field?
- Are there any events in your life that affected your grades, but are not reflected in the rest of your application?
3.While the standard INTRO, BODY, CONCLUSION essay is widely used, it is not required. It is used because it is an effective way to convey information:.
- INTRO: grabs reader's attention, tells the reader the main topic, gives necessary background information, and lists what is going to be expressed about the topic
- BODY: one paragraph per idea about the main topic (eg 1 for pros, 1 for cons; OR 1 telling about an event in your life, 1 explaining how that event affected you, 1 giving an example of how you used what you learned in a new situation)
- CONCLUSION: summarizes what you already told the reader, gives a broader context, and explains how the information is useful
4.To summarize: an essay is just a body of words that expresses an idea. There are many ways to write one, but having an introduction, paragraphs separated into ideas, and a conclusion helps make your idea easier to understand and more memorable.
Answer:
1.7 J
Explanation:
The energy carried by a single photon is given by
E=hf
where h is the Planck's constant and f is the frequency of the photon.
The photon of our exercise has a frequency of f=1.7 \cdot 10^{17} Hz, therefore its energy is
E=hf=(6.63 \cdot 10^{-34}Js)(1.7 \cdot 10^{17} Hz)=1.1 \cdot 10^{-16} J
