What is the formula for displacement?
∆ = xf − xi
v = /
v = ∆/
∆ = v ∙ t
Choose all that apply
Answers
Answer:
Explanation:
Displacement is the change in an object's position from the origin. Displacement is a vector quantity, and thus has both magnitude and direction. Displacement = (final position) - (initial position) = change in position. D = Xf -Xi. D = displacement.

Which of the following correctly explains a difference between the Steady State and Big Bang theories?
The Steady State theory says the galaxies are moving; the Big Bang theory says the galaxies are not moving.
The Steady State theory says the universe is getting smaller; the Big Bang theory says the universe is getting bigger.
The Steady State theory is supported by more evidence; the Big Bang theory is supported by less evidence.
The Steady State theory says the universe was always there; the Big Bang theory says the universe
Answers
Answer:
The Steady State theory says the universe is getting smaller; the Big Bang theory says the universe is getting bigger.
Big Bang theory: as the universe gets bigger we have the same galaxy’s and no more get created so in short the matter dilutes as the universe expands

The graph shows the constant speed of a train.
What is the speed of the train?
A. 1200 km/h
B. 300 km/h
C. 75 km/h
D. 4 km/h
Answers
Answer:
75 km/h
Explanation:
Speed = Distance divided by Time.
The train went a distance of 300 km in 4 hours. Therefore, the speed of the train is: 300 divided by 4 = 75 km/h
The speed of the train is equal to 75 km/h. Therefore, option (C) is correct.
What is speed?The speed of a body can be defined as the distance traveled by an object in a particular time interval. The average speed can be defined as a scalar parameter as it exhibits only the magnitude but not the direction of motion.
The speed of an object can be calculated from the ratio of the distance of the object to the time required to cover that distance.
The equation for the calculation of the speed can be written as follows:
Speed = distance /time taken
From the graph, at t = 2 h, the distance covered by train = 150 km
At time t = 4 h, the distance covered by train = 300 km
[tex]\displaystyle Speed = \frac{300-150}{4-2}[/tex]
Speed = 150/2
Speed of the train = 75 Km/h
Therefore, the speed of the train is 75 km/h.
