Here are 60 important GCSE Physics terminologies:Force - A push or pull on an object, measured in newtons (N).Mass - The amount of matter in an object, measured in kilograms (kg).Weight - The force of gravity a
How many joules of energy does a 100-watt light bulb use per hour? How to convert square feet to square meters with a formula What equipment digitally measures the mass of an object? Convert 15 cm to mm, m, and km What is the gravitational force measured in?
When was the inclined plane invented? An electric stair lift applies a force of 600 newtons directly upwards, moving the lift at a constant velocity of 0.1 meters per second. The power used by the stair lift is the scalar product of the force and velocity. If the stairs are at an angle...
The energy in a spark is calculated: Energy in Joules = ½CV2. Brush Discharge - usually happens when a corner of a machine part concentrates the charge in a larger sheet or web of non-conductive material. Generally lower in energy than a spark and so less incendive. Propagating Brush ...
The moon is just entering the waning gibbous phase. In approximately how many days will it enter the waning crescent phase? (a) What is the average power consumption in watts of an appliance that uses 5.00 kW\cdoth of energy per day? (b) How many joules of energy does this appliance ...
The description of force can be given from Newtonian theory, in which through the second law of Mechanical Physics proposed by Newton is defined as the product between mass and acceleration. This force has vector characteristics so it has a magnitude, meaning and d...
Power is defined as the rate of doing work per unit of time. It can also be defined as the rate of consuming energy per unit of time. The power can be mathematically expressed as follows: {eq}P\ =\ \dfrac{W}{T} {/eq} Where, ...
The SI unit of energy is Joules and its symbol is {eq}J{/eq}. There are various forms of energy, such as potential energy, kinetic energy, nuclear energy, thermal energy, chemical energy, electrical energy, etc. Regardless of the form of energy, each e...
Answer and Explanation:1 The amount of charge that passes per unit time is calledb. current. One can define current in terms of derivatives as: {eq}\displaystyle I =...
What is the gain in kinetic energy of an electron accelerated through this potential difference? Give the answer in both electron-volts and joules. (Assume that there Imagine adding electrons to the pin until the negative charge has a very large value of 1.04 mC. ...
