This could be wrong but I am giving a decent suggestion: All ions are atoms with a negative charge.
Answer:
unequal
Explanation:
White light is a combination of all colors in the color spectrum.
Answer:
The size of the force that pushes the wall is 12,250 N.
Explanation:
Given;
mass of the wrecking ball, m = 1500 kg
speed of the wrecking ball, v = 3.5 m/s
distance the ball moved the wall, d = 75 cm = 0.75 m
Apply the principle of work-energy theorem;
Kinetic energy of the wrecking ball = work done by the ball on the wall
¹/₂mv² = F x d
where;
F is the size of the force that pushes the wall
¹/₂mv² = F x d
¹/₂ x 1500 x 3.5² = F x 0.75
9187.5 = 0.75F
F = 9187.5 / 0.75
F = 12,250 N
Therefore, the size of the force that pushes the wall is 12,250 N.
did you mean what activities are performed during the cool down?
Answer:
Explanation:
Given
mass of object 
kinetic Energy 
Tension in string 
mass is moving in a horizontal circle so tension is providing the centripetal acceleration
therefore 
where r=radius of circle
kinetic energy of particle 
divide 1 and 2 we get
