Answer:E
Molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly. Wavelength always increases with speed, as frequency is fixed at source and speed= freq x wavelength
The speed of sound in room temperature air is 346 meters per second.
Let's see
Now we know the formula of acceleration
Or
Yes because if energy could have a positive change why can you not have a negative change
Assuming brown hair (B) color is completely dominant over blond hair (b), then the father's genotype must be bb.
