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?
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 f...
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...
Classical mechanics is based on these laws as these laws define the motion of the moon around Earth, the motion of balls on ground, the motion of bacteria, etc.Answer and Explanation: If we are standing on a scale in an elevator, the scale measures the normal force on ...
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 ...
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 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...
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 =...
