Electrical shock is most likely to be fatal when the path of the current is through the heart.
Answer:
a)

b)

Explanation:
a)
= mass of the asteroid = 43000 kg
= initial speed of asteroid = 7600 m/s
= final speed of asteroid = 5000 m/s
= Work done by the force on asteroid
Using work-change in kinetic energy theorem

b)
= magnitude of force on asteroid
= distance traveled by asteroid while it slows down = 1.4 x 10⁶ m
Work done by the force on the asteroid to slow it down is given as

Answer:
yes it is
Explanation:
when the speed increases the car will vibration than egg will breaks
Answer:
After one half of the battery's useful life.
Explanation:
Batteries of the emergency locator transmitter (ELT) must be replaced or recharged after one half of the battery's useful life because if it is exposed to the high temperature for a long period of time such as the air plane parked in the sun will result in the deterioration of battery which may makes the transmitter out of order before the expiry date of the battery. So it will be safe to do that after the use of one half of the battery's life.
Magnesium is in group 2 while sulfur is in group 6.
the group number determines the number of valence electrons.
Metals gives lose electrons (mg)
Non Metals gain electrons (s)
answer: Magnesium gives 2 electrons to sulfur.
Mg is now 2.8
Sulfur is 2.8.8
cuz ionic bonding
