Answer:
60 km/hour.
Explanation:
We'll begin by calculating the total distance traveled by the car. This is illustrated below:
Total distance traveled = sum of distance between PQRST
Total distance = 10 + 5 + 10 + 5
Total distance = 30 km
Next, we shall convert 30 mins to hour. This can obtained as follow:
Recall:
60 mins = 1 hour
Therefore,
30 mins = 30/60 = 0.5 hour.
Finally, we shall determine the average speed of the car as follow:
Distance = 30 km
Time = 0.5 hour
Speed =?
Speed = distance /time
Speed = 30/0.5
Speed = 60 km/hour
Therefore, the speed of the car is 60 km/hour.
Answer: A. Scott and Karla
Explanation: Velocity includes speed AND direction.
Because these both are different quantities,one is gravitational acceleration while other is the proportionality constant."g" can vary as it is the rate of change of velocity of any mass over which gravitational force is acting."g" changes due to different factors,like altitude etc.But "G" being a constant has non variable value.
Answer:
Probably 2 But it might be 1 :)
Explanation:
The weight of an object is given by
where m is the mass of the object, while g is the strength of the gravity (which corresponds to the gravitational acceleration of the planet).
In our problem, the shoes have a mass of m=0.5 kg, and their weight is F=11.55 N. So, we can re-arrange the previous formula to find the value of g:
and this is the strength of the gravity on Jupiter's surface.
