Hi, need help with this physics question in the picture ASAP.
Thank you.
Question 1 Center 7.30 nC of charge is uniformly distributed along a thin rod of length L4.20 cm, which is then bent into a semicircle as shown in the figure. What is the magnitude and direction of the electric field at the centre of the circle? Magnitude: Direction, given as an angle measured counterclockwise from the positive x axis:

Please don't answer the question by submitting a picture of solution, text only. For college physics discussion post. Be sure to have examples. Respond to the following: Explain conservation of momentum and give examples in daily life. In your own words, explain impulse and give examples in daily life. In your own words, center of mass and give examples in daily life.

Question 2 The positive and negative plates of a parallel-plate capacitor have an area of 3.60 cm by 3.60 cm. Their surface charge densities are +1.00x10-6 C/m2 and -1.00x10-6 C/m2, respectively. A proton moving parallel to the plates enters the middle of the space between them at a speed of 4.75x106 m/s. Assuming the field outside the capacitor is O and the field inside is unifornm...
Hello,
I'm having some trouble with this physics question, any help is
appreciated thanks!
A beam of monochromatic light passes from air to water (n = 1.33) to glass (n = ?). The two interfaces are parallel to each other, and the angle of incidence in air is 26 degrees, and that in the glass is 18 degrees. What is the index of refraction of the glass? Keep 2digits after decimal point. Your answer should be formatted like: 0.00
Please answer this question in the top left of the picture and
help me how to do it! the other stuff is to guide you through it.
The answer is below
Please help!! I'm not sure how to do the derivation, so a step
by step picture of the work would be fantastic. Thanks so much!
please help me with this question- i am stuck on it...
THANKS
please show the work- answer should be in METERS.
THANKS
