What is Physics? Understanding the Basics of Physical Science Physics is a branch of science that deals with the study of matter and energy and their interactions. It is the study of the natural laws and phenomena that govern the behavior of the universe. Physics is a fundamental science, as it provides a basis for … Read more
What do you mean by the value of magnification? The value of the magnification is 1.25 means that the object is magnified. The ratio of the length of the image to the length of the object is 1.25.
Write down two similarities between plane mirror and convex mirror. Two similarities between plane mirror and convex mirror are given below: 1) In both mirrors, always straight and virtual image is created. That’s why it cannot be put on a screen. 2) In both mirrors, never magnified image is created.
Why concave mirror is a convergent mirror? If a glass sphere is cut down and mercury is added to the convex side of the sphere so that light will be reflected from the inside concave shape, then it is a concave mirror.
What is the relation between force, pressure, area? The relation between force, pressure, area is given below – Pressure = Force ፥ Area
What is pressure? Pressure is a measure of the force exerted on a surface per unit area. It is a scalar quantity expressed in units of force per unit area, such as pascals (Pa), pounds per square inch (psi), atmospheres (atm), or millimeters of mercury (mmHg). Pressure results from the weight of a column of … Read more
Why it is not possible to avoid random errors? Random error is inherent in all measurement and observation processes, and it is not possible to completely eliminate it. Random error is caused by unpredictable and uncontrolled factors, such as measurement inaccuracies, variations in conditions, or limitations of the measuring instruments. These sources of error cannot … Read more
The acceleration is not created when the velocity is changed. We know, the rate of change of velocity concerning time is called acceleration. If a body does not move with velocity then we say there is no velocity. So the velocity is zero. As a result, the rate of acceleration is zero. Since the acceleration … Read more
