When an object's atoms move faster, its thermal energy increases and the object becomes warmer.
The answer is: Salt! :)
Have a great day!
Answer:
E = 0.437 N/C
Explanation:
Given that,
Charge, 
Electric force, 
Let the strength of the electric field is E. We know that, the electric force is given by :
F = qE
Where
E is the electric field strength
So, the strength of the electric field is equal to 0.437 N/C.
Answer:
7.5secs
Explanation:
Using the equation of motion
v = u + at
v is the final velocity = 0m/s
u is the initial velocity = 9m/s
a is the deceleration = -1.2m/s²
t is the required time
Substitute;
0 = 9 + 1.2(t)
-9 = -1.2t
t = -9/-1.2
t = 7.5secs
hence it takes the child 7.5secs to stop
Evidence that seismic waves transfer energy without transferring matter: Seismic waves do not transfer matter because the waves travel away from the faults because the movement in the crust occur along the faults as the seismic waves continue to travel away.
