Answer:
400 N
Explanation:
Change of Kinetic Energy to Friction Wok
∆KE = W
½ x m x (v(5)² - v(3)²) = f x d
½ x 500 x (5² - 3²) = f x 10
250 x (25 - 9) = f x 10
25 x 16 = f
f = 400 N
Answer:
Explanation:
We are given that
Distance between the wires,
1mm=
Length of other wire,l=0.3 m
Length of one wire is infinite.
We have to find the magnitude of force between the two wires.
We know that magnetic force
Where 
When the wires carrying equal current in opposite direction then the force between two wires repel to each other.
Acoustic Energy
Sonar uses the echo principle by sending out sound waves underwater or through the human body to locate objects
