They're all complete circuits, but 'A' won't DO anything, because it has nothing to make electrons want to flow around it (like a power supply, a solar cell, a battery etc).
Answer:
B) The mass of the reactants equals the mass of the products.
Explanation:
In any balanced chemical reaction, it is known by default that the mass of the products and reactants must always be the same.
This is according to the law of conservation of mass.
- Every chemical reactions obey the law of conservation of mass.
- The law states that "In every chemical reaction, matter is neither created nor destroyed but changed from one form to another".
- In essence, there is no mass loss in a chemical reaction.
- This law is usually shown by the balancing of chemical species on both sides of the equation.
Answer:
Both balls hit the ground simultaneously
Explanation:
Let´s call b₁ ( the ball dropped ) the equation for a free fall movement is, tacking as the origin of coordinates the level from which it was dropped
V = g*t ( since V₀ initial velocity is 0 )
In the case of projectile movement the equation for Vx and Vy (these speeds are independent)
are:
Vx = V₀x (constant) and Vy = Voy + g*t
Vy = V₀ * sin 0⁰ + g*t Vy = 0 + g*t
As we can see V is the same in both cases then the balls hit the ground simultaneously
Answer:
a.)
b.) 5 blocks
Explanation:
Let's find the volume of the metal block:
Now, let's find the volume of the smaller blocks:
So, one small block has a volume of 8cm. If the volume of the larger block is 40cm, we can fit a total of 5 smaller blocks into the larger block, meaning it will make up the same volume.
Answer:
It spreads out into multiple shadow regions
Explanation:
- when the waves meet the barrier than light is diffracted as When this occurs, the wave bends around the corners of the barrier or passes through the opening of the wedge, which acts as a barrier, forming several patterns with the hole shape of the wedge.
- and The main condition for this phenomenon to occur is that the magnitude of the barrier must be equal to the magnitude of the wavelength.
- when sunlight as an electromagnetic waves is passes by key hole of gate, then this light will break and form many keyhole-shaped shadow fields.
