<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.
Just find the density of every metal and select the one with a density of 2.71 g/cm³ . This is:
Metal 1
ρ = m/V
ρ = 22.1 g / 3 cm³
ρ = 7.367 g / cm³
Metal 2
ρ = m/V
ρ = 42 g / 4 cm³
ρ = 10.5 g / cm³
Metal 3
ρ = m/V
ρ = 9.32 g / 5 cm³
ρ = 1.864 g / cm³
Metal 4
ρ = m/V
ρ = 8.13 g / 3 cm³
ρ = 2.71 g / cm³
<h2>R / Metal 4 was selected.</h2>
Answer:
Two objects will have the equal velocities but the forces on both of them will not be equal. The equal velocities of these objects are due to their equal acceleration.
Explanation:
From the newton's equation
so here we can say that velocity does not depends on the mass.
The acceleration of both objects will be same but not the forces because
F = Ma
As the force is depending on the mass so it will not be the same for both objects.
Answer:
KE = 250 kg/m/s
Explanation:
use the formula: KE = 1/2 m (v^2)
KE = 1/2 (5) (10^2)
KE = (2.5) (100)
KE = 250 kg/m/s
