Answer:
Explanation:
are inversely proportional- the longer the wavelength the shorter the frequency.
Answer:
The force applied to the object is an external force, from outside the system. When it does positive work it increases the gravitational potential energy of the system. Because gravitational potential energy depends on relative position, we need a reference level at which to set the potential energy equal to 0.
By calculating the answer
Answer:
They both have the same density.
Explanation:
Density = mass/volume
10g ÷ 4 = 2.5
13g ÷ 5.2 = 2.5
Answer:
Sample B
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. Since the speed for Sample B is higher this means it has a higher temperature as well.
