An electron is projected horizontally at a speed of 1.2x10^7 m/s into an electric field that exerts a constant vertical force of 4.5x10^-16 N on it.The mass of the electron is 9.11x10^-31 kg.Determine
Lightbulbs are rated by their brightness (power), assuming they are connected to a 120 V source of voltage. A lightbulb that is printed with a rating of 45 W is connected to a 95 V source. Assume the
An ant is crawling on a horizontal flat tables surface. In polar coordinates, his coordinates are r(t) = bt^2 and theta(t) = (omega)t where b and omega are known constants.
a) Find his velocity funct
1) Time taken for ball to hit ground?
2) How fast is ball moving when it hits the ground?
3) Total distance moved by the ball?
Any tips or equations needed are greatly appreciated. Thanks in advance.
You are familiar with the concept of weight: the force on an object, near or at the surface of the earth, due to its gravitational interaction with the mass of the earth. Using this observation, and a
Assume that we have two vectors of equal magnitude. In the common visual representation of vectors by arrows these two vectors are:
1.represented by arrows of equal length.
2.represented by arrows of
Need to write a 500 word essay on the 7 SI units and what the standards are based on for physics class. I know what the 7 are, but Im stuck on what they are based on.-In order left to right of Quantit

True.
In metallic bonding each metal atom donates an electron which becomes delocalised. These electrons ability to move means they can carry both charge and heat (from one area to another0 and ther
A uniform board is leaning against a smooth vertical wall. The board is at an angleabove the horizontal ground. The coefficient of static friction between the ground and the lower end of the board is
No, but they have gone very very close. The current lowest temperature record, set in 1999, is 100pK. That is, 0.0000000001 deg C above absolute zero.-No, because all matter has *some* energy, just by
