Answer:
Distance traveled by car in 25 L IS 396.15 km
Explanation:
We have given average millage of car = 60 km /gal
Means car travel 60 km in 1 gallon
The amount of gasoline = 25 L
We know that 1 L = 0.2641 gallon
So
As the car travels 60 km in 1 gallon
So traveled distance by car in 6.6025 gallon of gasoline = 60×6.6025 = 396.15 km
Answer:
-78.4 cm
Explanation:
We can solve the problem by using the lens equation:
where
p is the distance of the object from the lens
q is the distance of the image from the lens
f is the focal length
Here we have
p = 80.0 cm
q = -39.6 cm (negative, because the image is on the same side as the object , so it is a virtual image)
Substituting, we find f:
Answer:
19.62 ms
Explanation:
t = Time taken = 2 s
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.81 m/s² (downward direction is taken as positive)
Equation of motion
The speed of the pebble when it hit the water is 19.62 ms
