The average velocity of the object represented by the distance time graph is 
- The velocity of an object is the change in the distance moved by an object with time.
- This could also be related to the rate of change or slope of the graph.
- Average velocity =
- Average velocity =
Therefore, the average velocity of the object is

C. The light bulb will be off
This is due to the reason that the wire doesn’t go back to the battery :)
Answer:
force = 0.20N .F = m ×a .& a = v/t then the f = m×v/t.
Explanation:
Answer:
T= 37 day
Explanation:
To solve this exercise we will use the definition of angular velocity as the angular distance, which for a full period is 2pi between time.
w = T / t
The relationship between angular and linear velocity is
v = w r
w = v / r
We substitute everything in the first equation
v / r = 2π / t
t = 2π r / v
Let's reduce to the SI system
V = 2 km / s (1000m / 1km) = 2 10³ m / s
r= R = 6.96 10⁸ m
Let's calculate
t = 2π 6.96 10⁸/2 10³
t = 3.2 10⁶ s
T = t = 3.2 10⁶ s ( 1h/3600s) (1 day/24 h)
T= 37 day
Point of correction, spring constant is 2.3×10−2 m not 2.3×10−2 m m
Answer:
28577 N/m
Explanation:
From Hooke's law, F=kx where F is force applied, k is spring constant and x is compression
F=mg=67*9.81
Approximately, 28577 N/m
