Do projectiles have a predictable path? Projectiles do not follow a predictable path. Where will the ball have the smallest speed? The speed is smallest at the highest point of its flight path because the y- component of the velocity is zero. At what point of the projectile path the speed is i minimum and […]

What are the main factors of contact metamorphism? The main factors that control metamorphic processes are: The mineral composition of the parent rock. The temperature at which metamorphism takes place. The amount and type of pressure during metamorphism. The types of fluids (mostly water) that are present during metamorphism. The amount of time available for […]

What is 5dBi range? This antenna would typically replace standard 2dBi antennas, which are normally shipped with this class of wireless device, in order to increase the range and/or expand the coverage area. With this 5dBi antenna, theoretically a distance of about 500 meters can be covered. Why gain is measured in dB? In electronics, […]

Can you wire a 3 pin plug with 2 wires? No, it’ll be fine. You need an earth wire when you’ve got metal casings on appliances; the earth wire provides a preferred path to ground for a fault which results in the casing becoming live (ie, a preferred path to that path being ‘you’). Can […]

What are the forces on members AC and BD? Question: In The Truss Shown Below: What Are The Forces In Members AC And BD? AC = 11000 N [Tension] BD = 7850 N [Compression] AC = 11000 N [Tension] BD = 7850 N [Tension] AC = 11250 N [Tension] BD = 7906 N [Compression] AC […]

What does not affect braking distance? Visibility is one of a number of factors that do not affect your braking distance per se but can inhibit your thinking distance. The longer it takes for you to spot hazards in the road, the more time will have passed before you hit the brake pedal. What factors […]

How do you interpret Q1 and Q3? The first quartile, denoted by Q1, is the median of the lower half of the data set. This means that about 25% of the numbers in the data set lie below Q1 and about 75% lie above Q1. The third quartile, denoted by Q3, is the median of […]

Do more bushels of potatoes grow when the soil is fertilized? An investigation found that more bushels of potatoes were produced when the soil was fertilized more. Students measured the temperature of the water at different depths in Lake Skywalker and found that the temperature varied. Does potatoes need to be fertilized? As you will […]
