What is kinematics in physics? If vector 1 has a magnitude of 3, and a direction of 30 degrees below the negative x-axis, and vector 2 has a magnitude of 4, and a direction of 80 degrees below the negative x-axis. What will be the ...
In the world of physics, acceleration, velocity, and forces are all represented by vectors. A vector is a quantity that has both a direction and a magnitude. A magnitude is an abundance or a mathematical amount of something. Displacement is also a vector quantity, which is the difference in...
What is the difference between a scalar quantity and a vector quantity in physics, and provide examples of each.相关知识点: 试题来源: 解析 标量只有大小,矢量有大小和方向;例子:标量如质量、温度,矢量如速度、力 1. **标量定义**:标量仅由数值大小描述,无方向。例如质量(kg)和温度(℃),只需数值...
Science Physics Motion (physics) What is a motion diagram?Question:What is a motion diagram?Motion:Motion is referred to as the change in position of a body over a period of time. The motion of an object is primarily described using its displacement, velocity or speed and acceleration. In...
In the physics world, the term vector means a dimension or direction. But in embedded programming, vector means memory address. Hence, a vector table is a table that contains memory addresses. But the question is, addresses of which piece of code or instructions? The answer is interrupts or...
It is a well-known fact that if the water is to flow out of a pipe, the water needs to have a force or “pressure” pushing it, either from gravity or a mechanical pump. Electrical Circuit Diagram Compared to a Water Pump In our analogy: Voltage is the pressure that forces the ...

NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
In case of closed surfaces the area vector is directed outwards the surface. But what is the direction of the area vector in case of an open surface e.g. A thin lamina type of surface.Does it depend upon the curvature of the surface i.e. concave or convex side. general-physics Physic...
Similarity search is a fundamental technique in data science, used to find data points in a dataset that are 'nearest' to a given query; as these searches are often within a vector space, it is also known as “vector search.” Such searches are used by systems such as voice recognition,...
