Question: A 0.15g honeybee acquires a charge of 21pC while flying. The electric field near the surface of the earth is typically 100N/C , directed downward.
A). What is the ratio of the electric force on the bee to the bee's weight? Fe/W = ?
B). What electric field strength would allow the bee to hang suspended in the air? (in N/C)
C). What would be the necessary electric field direction for the bee to hang suspended in the air? Upward, downward or horizontally directed?
calculate the mass of an object that can be used as a counterweight to create an applied force necessary to balance the load
In an experiment on the photoelectric effect, a metal is illuminated by light. Electrons are emitted when the light's wavelength is less than 670 nm. What is the metal's work function
A 1000 kg aircraft going 25 m/s collides with a 1500 kg aircraft that is parked and they stick together after the collision and are going 10 m/s after the collision. If they skid for 5.4 seconds before stopping, how far did they skid?
Side-by-side boxplots offer a different look at the data. Group the data into periods of roughly equal length: 1917 to 1939, 1940 to 1962, 1963 to 1985, and 1986 to 2010. Make boxplots to compare ice breakup dates in these four time periods.
A helicopter flies over the arctic ice pack at a constant altitude, towing an airborne 145-kg laser sensor which measures the thickness of the ice. find the tension in the cable towing the sensor
A 300 g bird flying along at 5.7 m/s seesa 10 g insect heading straight toward it with a speed of 35 m/s (as gauged by an observer on the ground, not by the bird). The bird opens its mouth wide and enjoys a nice lunch.
The position of an object is given as a function of time as x(t) = (-3.00 m/s)t + (1.00 m/s2)t2. What is the average speed of the object between t = 0.00 s and t = 2.00 s
An electron in a cathode ray tube accelerates across a potential dissimilarity 10.0 kv then passes through a small aperture. In one of the electrodes as it emerges on the other side of this electrodevit immediately enters a region in which a uniform ..
An object at rest explodes into three pieces. Two of them are equal in mass and break off at an angle of 88.7° to each other, both with a speed of 33.4 m/s. The last piece has four times as much mass as each of the other pieces. What is the magnitude..
The loaded cab of an elevator has a mass of 2.8 x 103 kg and moves 223 m up the shaft in 26 s at constant speed. Explain at what average rate does the force from the cable do work on the cab?
A 5.0 Ω resistor is connected in series with a10.0 Ω resistor. This combination is thenconnected in parallel with a 7.5 Ω resistor. Thethree resistor network is then connected in series with a15 Ω resistor. T
An object moves with constant acceleration 4.45 m/s2 and over a time interval reaches a final velocity of 12.4 m/s. If its initial velocity is 6.2 m/s, what is its displacement during the time interval
