To solve this problem we will apply the concepts related to the Doppler effect. The relationship given between the observed frequency and the actual frequency is given under the following mathematical function,
Here,
Rearrange the equation to obtain the frequency observed
Therefore the frequency of the emergency lights that you observe when it reaches you in your spaceship is
Answer:
If you use the same force to push a truck and a car, the car will have more acceleration than the truck because the car has less mass.
It is easier to push an empty shopping cart than a full one, because the full shopping cart has more mass than the empty one. This means that more force is required to push the shopping cart.
When a person kicks a ball the person exerts force in a specific direction, that is the direction in which it will travel. In addition to this, the stronger the ball is kicked, the stronger the force we put on it and the further away it will travel.
Suppose two people are walking and among the two people, if one is heavier than the other, then the one weighing heavier will walk slower because the acceleration of the person weighing lighter is greater.
When riding a bicycle, the bicycle acts as mass and our leg muscles pushing on the pedals of the bicycle is the force.

Answer:
Weather on Earth is caused by heat from the sun and movement of the air.
Explanation:
All weather happens in the lower layer of Earth's atmosphere, which is a layer of gases surrounding Earth. The sun's heat warms the air in this layer to different temperature levels in different places.
