Answer:
An ion is an atom or group of atoms with a positive or negative charge. Ions form when atoms lose or gain electrons to obtain a full outer shell: metal atoms lose electrons to form positively charged ions non-metal atoms gain electrons to form negatively charged ions.
Explanation:
True it was a perfect running technique
Answer:
0.758 N
Explanation:
mass of ball, = 36 g = 0.036 kg
radius, r = 19 cm = 0.19 m
tangential velocity, v = 200 cm / s = 2 m /s
The tension is the string is equal to the centripetal force acting on the ball.
The centripetal force acting on the ball is given by
T = 0.758 N
Thus, the tension in the string is given by 0.758 N.
The volume of a substance can directly be calculated by
the ratio of mass and density. That is:
volume = mass / density
Since the mass is 4.5 kg or 4500 grams, therefore:
volume = 4500 g / (8.89 g / cm^3)
<span>volume = 506.19 cm^3</span>
