In a “minute to win it” game, cards are placed between cups to stack them. The contestant then pulls the card out in hopes that they will end with a set of stacked cups. Why does this work?
There is no friction between the card and the cup.
Inertia will keep the top cup from moving very far. Gravity will pull one cup on top of another.
The opening of the cup is so much bigger than the bottom, even though the cup moves they will both be stacked together.
Both cups are moved the same amount by the friction between them and the card.
Answer:
There is no friction between the card and the cup.
Explanation:
Answer:
The answer option to your question is A) - There is no friction between the card and the cup.

In a series circuit, electrons only flow along one path. Given this information, which of the following is an advantage of series circuits?
A.
The voltage is the same everywhere in a series circuit.
B.
Less resistance is produced as more devices are added to the circuit.
C.
Series circuits are simpler than parallel circuits.
D.
If one part of the circuit breaks, the other parts will still be able to operate.
Answer:
C. Series circuits are simpler than parallel circuits.
Explanation:
In series circuit, all the components are connected in single path of current flow. If one part of the circuit breaks, the whole thing would break and none of the other parts would work. The voltage is not the same everywhere. It is different across each component. In series circuit, net resistance is more as resistance of all the components connected in series are added up. So, the only advantage of a series circuit is that is simpler than the parallel circuits.

The phases where surfer’s most likely benefit include D. 1st Quarter and 3rd Quarter.
Surfers will benefit include during the 1st Quarter and 3rd Quarter because there's tidal change. Tidal change is when coastal areas experience two low and high tides.
The benefit of surfing during this period is that it helps jack the waves. Waves transmit energy and this is important to surfers.

As SCUBA divers go deeper underwater, the pressure from the weight of all the water above them increases tremendously which compresses the gases in their blood. What happens to the volume of gas in their blood as the diver rises quickly to the surface?
A.
As a diver rises, the pressure on their body decreases which allows the volume of the gas to decrease.
B.
As a diver rises, the pressure on their body increases which allows the volume of the gas to decrease.
C.
As a diver rises, the pressure on their body decreases which allows the volume of the gas to increase.
D.
As a diver rises, the pressure on their body increases which allows the volume of the gas to increase.
Answer: A.
As a diver rises, the pressure on their body decreases which allows the volume of the gas to decrease.
Explanation:
The problem is that a diver, experiences an increased pressure of water compresses nitrogen and more of it dissolves into the body. Just as there is a natural nitrogen saturation point at the surface, there are saturation points under water. Those depend on the depth, the type of body tissue involved, and also how long a diver is exposed to the extra pressure. The deeper a diver go, the more nitrogen the body absorbs.
The problem is getting rid of the nitrogen once you ascend again. As the pressure diminishes, nitrogen starts dissolving out of the tissues of the diver's body, a process called "off-gassing." That results in tiny nitrogen bubbles that then get carried to the lungs and breathed out. However, if there is too much nitrogen and/or it is released too quickly, small bubbles can combine to form larger bubbles, and those can do damage to the body, anything from minor discomforts all the way to major problems and even death.

6.
Answer:
45 meters
Explanation:
notice that is you multiply the time with the speed the units cancel to get distance.
therefore
distance=velocity(time)
distance=(3)15
distance =45 meters
7.
Answer:
1. the speed is constant
2. the average speed is .5 m/s
Explanation:
I have attached a graph of the data in excel.
from excel i got the equation of the line to be y=.5x with y being distance and x being time.
the function is a position function so if you take the derivative of it you get the velocity which is .5.
since the derivative is a constant the the speed does not change and the average velocity is the derivative.

if 34.7 g of O2 reacts with iron to form 79.34 g of iron oxide, how much iron was used in the reaction?
A.
19.84 g
B.
44.64 g
C.
104.1 g
D.
114.04 g
Answer: B. 44.64 g
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
Mass of reactants = mass of iron + mass of oxygen = mass of iron + 34.7 g
Mass of product = mass of iron oxide = 79.34 g
As Mass of reactants = Mass of product
mass of iron + 34.7 g = 79.34 g
mass of iron = 44.64 g
Thus 44.64 g of iron was used in the reaction

Suppose that you, with a mass of 48kg, is standing on frictionless roller skates when someone throws you a 2.50kg mass with a velocity of 15m/s and you catch it. What will be your resultant velocity?
Answer:
v = 0.74 m / s
Explanation:
We can solve this exercise using the conservation of the moment
initial instant. Before the crash
p₀ = m v
where m is 2.50 kg and its velocity v₀ = 15 m / s
final moment. After catching the dough
[tex]p_{f}[/tex] = (m + M) v
As the system is made up of the mass and the person, all the forces during the impact are internal, therefore the moment is conserved
p₀ = p_{f}
m v₀ = (m + M) v
v = m / (m + M) v₀
we calculate
v = 2.5 / (2.5 + 48) 15
v = 0.74 m / s
What is the resistance of a 6.0 m long gold wire (ρgold = 5.6 x 10 -8 Ω-m) whose cross-sectional area is 5x10 -7m 2 ? (Please show some work)
Answer:
R =0.672 ohms
Explanation:
We have,
Length of a gold wire is 6 m
Resistivity of gold is [tex]5.6\times 10^{-8}\ \Omega-m[/tex]
Area of cross section of the wire is [tex]5\times 10^{-7}\ m^2[/tex]
The resistance of a wire is given by the relation as follows :
[tex]R=\rho\dfrac{l}{A}\\\\R=5.6\times 10^{-8}\times \dfrac{6}{5\times 10^{-7}}\\\\R=0.672\ \Omega[/tex]
So, the resistance of the gold wire is 0.672 ohms.
