The components that must be present for work to be considered is a force and a movement in the same direction as the force. In the basic definition of work, a magnitude and displacement that occurs in the same direction is what makes up work. Among the choices, the correct answer is the first one.
Q.1
Answer . Momentum = mass x velocity
Momentum/mass = velocity
5/0.8 = velocity
6.25 m/s = velocity
Q.2
Answer . F = ma => a = f/m => a = 7/3.2 => a = 2.1875m/s²
The correct answer is (d), electrons are in probable cloud location.
An atom is made up of three fundamental particles, electron, proton and neutron. Proton and neutron are located in the nucleus, while the electrons orbit the nucleus in relative large orbit, however the exact position of the electron in the shall is highly unpredictable, therefore they are assumed to be in probable cloud location where the probability of finding an electron is very high.
Answer:
When one object heats another, the temperature increase of one object does not always equal the temperature decrease of the other object because one object has a higher specific heat than the other.
The distance from your eyes to the image of your toes in the mirror is 365 cm.
What is distance?
Distance as well as displacement are two key terms in mechanics that, despite having similar sounds, have distinct definitions and meanings. How much of an object's path has been covered by a moving object is measured in terms of distance. While "How much route is covered by object inside a particular direction" is measured by displacement, The main distinction between distance as well as displacement is therefore that the former is a scalar quantity while the latter is a vector quantity. Both quantities have had some similarities despite this distinction. Meters are used to measure both length and displacement (m). In this article, we'll learn further about distance as well as displacement by understanding some key ideas, such as what distance is, its mathematical definition, what displacement is, its mathematical definition, its differences, similarities, and examples.
This is because the mirror is 200 cm away from you, and the image of your toes in the mirror is 165 cm away from the mirror. Therefore, the total distance from your eyes to the image of your toes is 200 cm (distance from you to mirror) + 165 cm (distance from mirror to image of toes) = 365 cm.
