Answer:
See the explanation below.
Explanation:
Attached is a picture of a chocolate bar that can be easily found on the market. In this picture, we see the table of contents with the amount of energy that depends on the mass in grams of the chocolate bar.
We see that for the bar size of 100G, the energy value is 483 [kcal].
We can see that the energy depends on the size of the chocolate bar.
Answer:
11.87 ms⁻¹
Explanation:
You can use the kinematic equation
v² = u² + 2as
Where v = final velocity
u = initial velocity
a = acceleration
s = displacement
v² = 9² + 2×1.5×20
So you get v = 11.87 ms⁻¹
Answer:
a
Explanation:
the kinetic energy decreases which makes the molecules bond together, that makes them not be able to move much
Labels that belong in regions marked X and Y are;
A) X: Maintains magnetic properties in the presence of another magnet
Y: Is made from magnetically hard ferromagnetic material
