Answer :Scientific Definition of Inference
In science, there are a few different types of inferences, but in general an inference is: “An educated guess made through observation.” You might use these inferences to share a potential reason why something happens or how it happens.
Explanation:
Mechanical waves travel the fastest in
solids and liquids because the
molecules are more closely packed together than gases, so energy is transferred
from one particle to another particle faster<span>.</span>
Answer:
Voltage describes the potential difference between the two ends of a conductor and thus , more the voltage , more will be the flow of current through the conductor ( more no of electrons and faster speed).
Explanation:
Answer:
The net gravitational force exerted by these objects is
Explanation:
Given that,
Mass of another object m = 33.0 kg
Mass M₁ = 160 kg
Mass M₂ = 460 kg
Distance = 3.40 m
We need to calculate the net gravitational force
Using formula,
Where, G = gravitational constant
m = mass of another object
= mass of first object
= mass of second object
r = distance
Put the value into the formula
Hence, The net gravitational force exerted by these objects is
Answer:
NOT:
If copper is a better conductor, it will heat up faster than iron.
