Answer:
true
Explanation:
electric charge is determined by electrons and protons, which are subatomic particles.
When the wire is twice as long. Also when the cross sectional area is halved
The centripetal acceleration is the ratio of the tangential speed and the
radius of the shell.
The tangential speed of the part of the shell is approximately <u>0.12961 m/s</u>
Reasons;
The widest diameter of the egg, d = 12 cm = 0.12 m
The given centripetal acceleration,
= 0.28 m/s²
Required:
The tangential speed of the bird.
Solution;

Where;

v = The tangential speed
Which gives;


v² = 0.28 m/s² × 0.06 m = 0.0168 m²/s²
v = √(0.0168 m²/s²) ≈ 0.12961 m/s
The tangential speed, v = <u>0.12961 m/s</u>

Answer:
The alkaline earth metals (beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra)) are a group of chemical elements in the s-block of the periodic table with very similar properties: shiny. silvery-white. somewhat reactive metals at standard temperature and pressure.
