Answer:
4m/s2
Explanation:
The following data were obtained from the question:
U (initial velocity) = 10m/s
V (final velocity) = 30m/s
t (time) = 5secs
a (acceleration) =?
Acceleration is the rate of change of velocity with time. It is represented mathematically as:
a = (V - U)/t
Now, with this equation i.e
a = (V - U)/t, we can calculate the acceleration of the race car as follow:
a = (V - U)/t
a = (30 - 10)/5
a = 20/5
a = 4m/s2
Therefore, the acceleration of the race car is 4m/s2
The <span>x-values equal time (usually in seconds according to physics position vs. time graphs) and the y-values equal distance (usually in meters according to physics position vs. time graphs). I hope the answer helps. Thank you for posting your question here. </span>
Answer: S. G = m*V1 + mL*V2 + mA*V3 - m*V1
Explanation:
m = mass of solid object
mL = Object Apparent mass in an unknown liquid
mA = Apparent mass of object in water
V1 = volume of solid object
V2 = Volume of unknown liquid
V3 = Volume of water
Answer:
The total time is .
Explanation:
Given:
The distance between Galactic Capitol and Earth is,
The speed of light is,
The time taken by the message to reach and come back to Earth is given by
In addition they take 1 year to decide to reply.
Thus, the total time is .
