A body is said to be at absolute rest when that object is in the state of stationary. Absolute motion means a motion that does not depend on anything external to the moving object for its existance.
Absolute motion is motion that does not depend on anything external to the moving object for its existence or specific nature. Absolutists hold that there are many motions that appear the same no matter from what reference frame they are observed.
Answer:
2.5N
Explanation:
since force is inversely proportional to square of the distance apart. that means the ratio of distance apart. so u have 12800×12800÷(6400××6400)=4/1
so the weight will be reduced to 1/4 of 10N
Answer:
Approximately .
Explanation:
Assuming that there is no other force on this vehicle, the force from the road would be the only force on this vehicle. The net force would then be equal to this force. The size of the net force would be .
Let denote the mass of this vehicle and let denote the net force on this vehicle.
By Newton's Second Law of motion, the acceleration of this vehicle would be proportional to the net force on this vehicle. In other words, the acceleration of this vehicle, , would be:
.
For this vehicle, whereas . The acceleration of this vehicle would be:
.
Answer:
5 Km/h
Explanation:
From the question given above, the following data were obtained:
Distance travelled = 10 Km
Time = 2 hours
Speed =?
Speed is simply defined as the distance travelled per unit time. Mathematically, it can be represented as:
Speed = distance travelled /time.
With the above formula, we can obtain the speed at which the duck is travelling as follow:
Distance travelled = 10 Km
Time = 2 hours
Speed =?
Speed = distance travelled /time.
Speed = 10 / 2
Speed = 5 Km/h
Thus, the duck is travelling at a speed of 5 Km/h
