Answer:
The given statement concerning distance and displacement is true.
Explanation:
If any point travels along any path between two points A and B the distance it travels is the length of the actual path it travels.
Mathematically the distance between two points is the algebraic sum of the infinitesimal distances that the particle travels.
Mathematically
Displacement by definition is the shortest distance between the initial and final positions of the particle and is given by the straight line joining the two points.
Since a line is the shortest path that exists between 2 points thus it will be always smaller than any other path connecting the 2 points hence will be smaller than the distance.
While as if the object travels along a straight line without changing it's direction the distance in that case equals the displacement.
Answer:
0.16 m
Explanation:
A rectangular gasoline tank can hold 50.0 kg of gasoline when full, and the density of gasoline is 6.8 × 10² kg/m³. We can find the volume occupied by the gasoline (volume of the tank).
50.0 kg × (1 m³/6.8 × 10² kg) = 0.074 m³
The volume of the rectangular tank is:
volume = width × length × depth
depth = volume / width × length
depth = 0.074 m³ / 0.500 m × 0.900 m
depth = 0.16 m
Answer:
D. Equalize voltage
Explanation:
Of the following lead-acid battery the battery with voltage value is Equalize voltage. EQUALIZING lead acid battery is process of de-sulphating the battery by carrying out a controlled overcharge. When battery plates acquire sulphate coating over time, their efficiency reduces, by overcharging this sulpahte coating is blown-off and the battery is rejuvenated.
