Answer:
K.E = 156.25 Joules.
Explanation:
Given the following data;
Mass = 0.5kg
Velocity = 25 m/s
To find the kinetic energy;
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
Where;
K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents velocity measured in metres per seconds square.
Substituting into the equation, we have;
K.E = 156.25 Joules.
C because in order to make something go faster you need to increase it's velocity
The type of energy that depends on position is called
kinetic energy
Answer:
(D) Water is denser than oil but less than syrup.
Explanation:
Given:
A picture of a jar containing three liquids.
The position of the syrup is at the bottom of the jar. The position of water is in middle and the oil is at the top.
We know that, the oil is the lightest in density when compared to syrup and water. So, it is at the top.
Now, since water is in the middle of the two, it means that density of water is greater than that of oil but less dense than that of syrup.
So, the density of the syrup is the greatest. Hence, it sits at the bottom.
Therefore, the best explanation is that water being less dense than syrup but more dense than oil, will be in the middle of two.
This explains the position of all the three liquids. Water is in the middle, oil at top and syrup at bottom.
So, the last option is correct.
