A chemical energy ➡️Kinetic energy ➡️Heat energy
<h2>Answer:</h2>
The correct answer is option C which is, "empirical evidence that was collected during the experiment".
<h3>Explanation:</h3>
Empirical evidence are the observations and data values collected during the experiment by using the senses.
Like if your are experimenting involving a chemical reaction, the temperate or color changes during the reaction should be counted in the interpretation of the results.
Hence the correct option is C.
Answer:
the magnitude of the displacement after 5s is 137.31 m.
Explanation:
Given;
initial velocity of the projectile, u = 60 m/s
angle of projection, θ = 60°
time of motion, t = 5s
the vertical component of the velocity, 
The magnitude of the displacement after 5s is calculated as;
Therefore, the magnitude of the displacement after 5s is 137.31 m.
Normal force=m*g*cos theta
normal force=92kg*9.8m/s^2*cos 42
normal force=670 N
Answer:
Density is the relationship between mass and volume.
D = M / V
