What can a firewall not prevent? Users not going through the firewall: A firewall can only restrict connections that go through it. It cannot protect you from people who can go around the firewall, for example, through a dial-up server behind the firewall. It also cannot prevent an internal intruder from hacking an internal system. […]
Can a tsunami tip over a cruise ship?
Can a tsunami tip over a cruise ship? Experts agree that a cruise ship sailing out over a body of water is not likely to feel any impacts from a tsunami’s waves. Cruise ships closer to land or at port would face an immense threat from the tsunami’s tall, high-energy and potentially devastating wave. Can […]
What is the formula for calculating acceleration?
What is the formula for calculating acceleration? Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Does constant velocity have to be in a straight line? Yes. Velocity […]
What is best treatment for low bone density?
What is best treatment for low bone density? Pharmacologic treatment with alendronate, risedronate, zoledronic acid, or denosumab should be prescribed for women with osteoporosis to reduce the risk of hip and vertebral fractures. Pharmacologic treatment should continue for five years, during which time bone density monitoring should not be done. What happens if you have […]
How do bones muscles and joints work together?
How do bones muscles and joints work together? Muscles can pull bones, but they can’t push them back to the original position. So they work in pairs of flexors and extensors. The flexor contracts to bend a limb at a joint. Then, when the movement is completed, the flexor relaxes and the extensor contracts to […]
What is the charge on the other plate of the capacitor?
What is the charge on the other plate of the capacitor? Capacitors do not store charge. Capacitors actually store an imbalance of charge. If one plate of a capacitor has 1 coulomb of charge stored on it, the other plate will have −1 coulomb, making the total charge (added up across both plates) zero. How […]
Which is equal to 0.0079 in scientific notation?
Which is equal to 0.0079 in scientific notation? Therefore, the decimal number 0.0079 written in scientific notation is 7.9 × 10-3 and it has 2 significant figures. What is the scientific notation for 140000000? Why is 140,000 written as 1.4 x 105 in scientific notation? How do you write 0.72 in scientific notation? Therefore, the […]
Which ocean has strongest currents?
Which ocean has strongest currents? Antarctic Circumpolar Current What happens if deep ocean currents stop? The ocean currents carry warmth from the tropics up to these places, which would no longer happen. If the currents were to stop completely, the average temperature of Europe would cool 5 to 10 degrees Celsius. There would also be […]
What is the difference between amplitude and frequency modulation?
What is the difference between amplitude and frequency modulation? The main difference between both modulations is that in frequency modulation, the frequency of the carrier wave is modified as per the transmit data, while in amplitude modulation, the carrier wave is modified according to the data. What is the frequency of AM? The frequency band […]
