Answer:
A driver without a seat belt getting thrown from the car in a collision is an example of Newton’s 1st Law.
Explanation:
- Newton's first law is also known as Law of Inertia.
- Law of inertia states that a body tends to remain in its state of motion or state of rest until an unbalancing force acts on it.
- When a moving car suddenly collides with an object like a wall or other vehicle, it is acted upon by an unbalancing force which decelerates it and bring it to rest.
- In this case ,the driver who was sitting in the car without a seat belt does not get acted upon by the unbalancing force and his body tends to remain in motion.
- Due to this reason he is thrown away from the car.
- If he had been wearing the seat belt then the seat belt straps would have applied an unbalancing force force on the Driver and brought him to rest along with car.
Answer:
H Flies with long wings can produce offspring with short wings.
Explanation:
For example, if we name the gene for the wings length with A, then the fruit flies with short wings have the genotype aa (recessive homozygous), while those with long wings can have either AA (dominant homozygous) or Aa (heterozygous) genotype. So, if two fruit flies with long wings and Aa genotype are crossed:
P: Aa x Aa
F1: AA Aa Aa aa
There is a 25% chance that offspring will have short wings.
