When you compare all organisms around us, even the smallest ones, you see that they have Life; You could even see this as a trend of some sort.
Answer:
v = 1400 m/s
Explanation:
Acceleration of the rocket, a = -20 m/s²
Initial speed of the rocket, u = 1600 m/s
Time, t = 10 s
We need to find the final velocity of the rocket. We can use first equation of motion to find it.
v = u+at
Put all the values,
v = 1600+(-20) (10)
= 1600-200
= 1400 m/s
So, the final velocity of the rocket is 1400 m/s.
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
Answer:
It states that the rate of change of velocity of an object is directly proportional to the force applied and takes place in the direction of the force. It is summarized by the equation: Force (N) = mass (kg) × acceleration (m/s²). Thus, an object of constant mass accelerates in proportion to the force applied.
Explanation:
Answer:
From the negative to the positive cable.
Explanation:
The electrons have negative charge, which means that the negative terminal of the battery will suply the electrons, thus they are present in excess on the negative cable and will jump from it to the positive cable. This current direction is called real current.
