Answer:
distance = 6 m
Explanation:
- Distance is a scalar quantity (so, only magnitude, no direction), and it is calculated as the scalar sum of all the distances travelled by an object during its motion, regardless of the direction. So, in this problem, the distance covered by the pinecone is
d = 4 m + 2 m = 6 m
- Displacement is a vector quantity (magnitude+direction), and its magnitude is calculate as the distance in a straight line between the final position and the initial position of the object. In this case, the final position is 2 m west and the initial position is 0 m, so the displacement of the pinecone is
d = 2 m west - 0 m = 2 m west
So, a scalar quantity from this scenario is
distance = 6 m
Answer:
Ok, so the car has traversed a total of 2 + 4 + 2 + 6 = 14 miles.
That's the car's distance! :)
For the displacement, you can draw out a diagram. I'll try my best to make one using a keyboard xDDD
- - - - |

| - - - start - end!
So, this is the journey of the car: Going two up, 4 left, 2 down, and 6 right.
This ends up 2 to the right of the beginning!
That's a 2 mile displacement :)
Can you give me brainliest for my splendid diagram? xD
Answer:
ΔT = 0.29°C
Explanation:
Using the law of conservation of energy:
where,
ΔT = Temperature difference between the water at the top and the bottom of the fall = ?
g = acceleration due to gravity = 9.81 m/s²
h = height of fall = 125 m
C = specific heat capacity of water = 4200 J/kg
Therefore,
<u>ΔT = 0.29°C</u>
Answer:
<h2>6 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 36 g
volume = 6 cm³
We have
We have the final answer as
<h3>6 g/cm³</h3>
Hope this helps you
Answer:
4708.78 m
Explanation:
Applying,
d = vt................ Equation 1
Where d = displacement, v = velocity, t = time
dispalcement due west
Given: v = 23 m/s, t = 135 s
Therefore,
d = 23(135)
d = 3105 m due west.
For south
Given: v = 12 m/s, t = 295 s
Therefore,
d = 12(295)
d = 3540 m
Note: The entire journey forms a right angle triangle
Total displacement = √(3105²+3540²)
Total displacement = √(9641025+12531600)
Total displacement = √(22172625)
Total displacement = 4708.78 m
