Answer:
The speed of a turtle is 4m/s
Explanation:
speed = distance/time
distance = 100m
time = 25s
s = 100/25
= 4m/s
(A) The oxygen atom becomes strongly negative.
Explanation:
When a very electronegative atom like oxygen bonds to an atom with a lower electronegativity, like lithium, the oxygen atom becomes strongly negative and the lithium becomes strongly positive.
The attraction between these oppositely charged ions results in the formation ionic bond.
- An ionic bond is an interatomic bond in which a highly electronegative atom is bonded to less electronegative one.
- The electronegative nature of the oxgyen allows is to gain the electrons lost by weakly electronegative lthium.
- Most metals have low electronegativity.
- They then both will form ions.
- The attraction between the oppositely charged ions results in an ionic/electrovalent bonding.

Answer: 37.5 kg in 3 s.f.
Explanation:
Explanation:
The U.S. launched its first man into space in May 1961.
One form of Ohm's Law says . . . . . Resistance = Voltage / Current .
R = V / I
R = (12 v) / (0.025 A)
R = (12 / 0.025) (V/I)
<em>R = 480 Ohms</em>
I don't know if the current in the bulb is steady, because I don't know what a car's "accumulator" is. (Floogle isn't sure either.)
If you're referring to the car's battery, then the current is quite steady, because the battery is a purely DC storage container.
If you're referring to the car's "alternator" ... the thing that generates electrical energy in a car to keep the battery charged ... then the current is pulsating DC, because that's the form of the alternator's output.
