Electrical would be the energy that involves the flow of positive charges.
The rate at which the location of an object shifts in any direction. Speed is measured as the ratio of the distance travelled to the time it took to cover that distance. Speed is a scalar quantity since it just has a direction and no magnitude.
<h3>Explain about the speed?</h3>
It speaks of the motion of an object. Speed is calculated as distance travelled divided by time. Speed is measured in m/sec. Speed is a scalar quantity equal to the magnitude of the velocity vector. When a thing's speed is higher, it moves more quickly.
Speed refers to the rate at which a distance varies over time. It has a time-distance dimension. As a result, the SI unit of speed is created by combining the basic units of time and distance. As a result, the SI unit of speed is the meter per second (m/s)
The formula for an object's general speed is [Speed = Distance Time]. M/s is the SI unit of speed.

48 years, 1912-1960, July 4, the 50-star flag makes its debut in Philadelphia, Pennsylvania. A 50th star was added to the American flag in honor of Hawaii's August 21, 1959 admission into the Union
Answer:
a)801KJoules
b)The woman must climb stairs for an equivalent of 1.57km
Number of stairs=7850 stairs
Explanation:
a)We use the conversion between Joules and Kcal:
4184Joules=1Kcal
540Kcal*(1484Joules/1Kcal)=801KJoules
b)The physical Work must be equal to the food energy
The woman must climb stairs for an equivalent of 1.57Km
For example if an stair measure 20cm=0.2m
Number of stairs=1.57km/0.2m=7850 stairs
Answer:
conduction
Explanation:
Conduction transfers heat via direct molecular collision. An area of greater kinetic energy will transfer thermal energy to an area with lower kinetic energy. Higher-speed particles will collide with slower speed particles.
