The answer is Fuse, the Fuse has a low melting point
Answer:
Hey :)
Explanation:
Work is a net force applied through a distance in order to displace an object, commonly abbreviated as W. A net force is the sum of all forces acting on an object. Work is mass times acceleration and distance so to find out the work you simply calculate the acceleration of the box being brought in. Next find the distance it was carried to get in the house. Then find out the mas of the box and finally multiply those sums together to get the amount of work put in to bring the package inside.
hope this helps :) xo
Answer: screen
A mixture of sand, salt and iron can be separated using magnet, filter paper and water. Iron being a magnetic material, can be separated using magnet. The rest of the mixture, salt and sand can be mixed in water. The salt would dissolve in water but sand would not because sand is insoluble in water. This mixture can be filtered using a filter paper. The filter has very minute openings through which sand would not pass through and get separated. Then, salty water can be heated. The water would evaporate leaving behind salt.
In this whole process, screen would not be useful because it would depend on the size of the sand particles and available screen.
Answer:
I = 1.05x10⁻³ A
Explanation:
By definition, an electric current is the rate of charge flow at a given time:
Where:
q: is the electrons charge = 1.602x10⁻¹⁹ C
t: is the time
In a circular motion, the time is given by:
Where:
ω: is the angular speed = v/r
v: is the speed = 2.19x10⁶ m/s
r: is the radius = 5.29x10⁻¹¹ m
Now, the effective current is:
Therefore, the effective current associated with this orbiting electron is 1.05x10⁻³ A.
I hope it helps you!
