What decreases negative effects to a driver in a crash? If your vehicle is hit from behind while stopped, your head tends to stay in place due to inertia, while the rest of your body is pushed forward by the seat. Modern vehicles have features that reduce the forces on your body during a crash […]
What is the final velocity in free fall?
What is the final velocity in free fall? Near the surface of the Earth, an object in free fall in a vacuum will accelerate at approximately 9.8 m/s2, independent of its mass. With air resistance acting on an object that has been dropped, the object will eventually reach a terminal velocity, which is around 53 […]
What is T2 * used for?
What is T2 * used for? T2*-weighted sequences can be used with ferucarbotran or superparamagnetic iron oxide (SPIO) contrast agent enhancement to depict liver lesions (13,14). components in tissues, such as deoxyhemoglobin, hematoma, or calcification, and can be used for differentiating the susceptibility differences among tissues (17). What is a T2 * in MRI? T2 […]
Does TV use microwaves or radio waves?
Does TV use microwaves or radio waves? Microwaves are used because they pass through the atmosphere and through the ionosphere. The signals may be for television programmes, telephone conversations, or monitoring the Earth (for example, weather forecasting). Should I turn off wifi at night? The BEST Way To Shut Off WiFi At Night Safely and […]
What is Biot Savart law and its application?
What is Biot Savart law and its application? The Biot Savart Law states that it is a mathematical expression which illustrates the magnetic field produced by a stable electric current in the particular electromagnetism of physics. This law is applicable in the magnetostatic estimate, & is reliable by both Gauss’s (magnetism) and Ampere’s (circuital) law. […]
What are 3 ways to prevent beach erosion?
What are 3 ways to prevent beach erosion? Since erosion is unavoidable, the problem becomes discovering ways to prevent it. Present beach erosion prevention methods include sand dunes, vegetation, seawalls, sandbags, and sand fences. What happens to a beach when a wave’s backwash is stronger than its swash? If the swash is stronger than the […]
How do you classify hydrogen?
How do you classify hydrogen? Hydrogen is most often classified as a nonmetal because it has many of the properties of nonmetals. For example, it is a gas at room temperature. However, hydrogen shares properties with the alkali metals in group 1. In liquid form, hydrogen conducts electricity just like a metal does. Can we […]
What are two recently discovered state of matter?
What are two recently discovered state of matter? The two newly discovered states of matter are Plasma and Bose-Einstein Condensate. Does liquid glass exist? Glass, however, is actually neither a liquid—supercooled or otherwise—nor a solid. It is an amorphous solid—a state somewhere between those two states of matter. And yet glass’s liquidlike properties are not […]
