Answer:
it comes under physical property of that particular substance
Explanation:
color, melting point, boiling point, sonorous these kinda properties come under physical properties of a metal or a non-metal or any other substance you prefer
Answer:
The force acting on the ball is 92.4 N.
Explanation:
Given that,
Initial speed of the ball, u = 0
Final speed of the ball, v = 31.6 m/s
The average power generated during the serve is 2920 W. Power generated by an object is given by :
W is the work done, W = Fd
Since,
So,
F is the force acting on the ball
So, the force acting on the ball is 92.4 N. Hence, this is the required solution.
Answer:
E) d/sqrt2
Explanation:
The initial electric force between the two charge is given by:
where
k is the Coulomb's constant
q1, q2 are the two charges
d is the separation between the two charges
We can also rewrite it as
So if we want to make the force F twice as strong,
F' = 2F
the new distance between the charges would be
so the correct option is E.
Less water would be evaporated
Answer:
Magnetic field at the center of the loop
Explanation:
It is given that total length of wire is 2 m and number of circular loop is 5 turns.
Therefore ,
We know , magnetic field at the center of loop is given by :
Putting all values in above equation we get :
Hence , this is the required solution.
