A. New and Full Moon
B. New moon and Waxing Crescent
C. Full Moon and Waxing Gibbous
D. 1st Quarter and 3rd Quarter
Answers
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.

Which are descriptions of gravity on Earth? Check all that apply.
an attractive force
a repulsive force
a noncontact force
a contact force
a horizontal force
a vertical force
Answers
Answer:
an attractive force
a noncontact force
a vertical force
Explanation:
Gravitational force is a NON-CONTACT FORCE. Gravitational force acts on all bodies on the earth that have mass. The force which is exerted through weight acts on the center of gravity of the body. The force is directed towards the center of the earth. The weight of a body is the gravitational force exerted by the earth on the body.

At what point in a waterfall, do the drops of water contain the most gravitational potential energy?
Answers
Answer:
The water above receives energy as it falls down the short waterfall. This energy was stored as potential energy in the gravitational field of the Earth and came out of storage as the water dropped. This energy which came out of the gravitational field ended up being expressed as the kinetic energy of the water. That is, the water gains kinetic energy as it drops. An ounce of water is going faster when it hits the bottom of the waterfall than it was when it went over the top of the waterfall
Explanation:
The drops of water contain the most gravitational potential energy at the top before they start falling.
At the top of the waterfall
GravitationAt the top of the waterfall, the water drops have the most gravitational potential energy before they start falling as the water at the peak of the waterfall is higher in the Earth's gravitational field and has gravitational potential energy. The potential energy is converted to kinetic energy when it falls. As a result, energy is not created; it was always there, stored as potential energy.
Potential energy is energy that is stored and is determined by the relative positions of various pieces of a system. Kinetic energy is the energy that an item or particle has as a result of its movement.

When a current flows through a light bulb, it emits 30 J light energy in 2 seconds, What is the power of the bulb?
Answers
The power of the light bulb is 15 watts.
What is power ?Power in physics is defined as the rate of energy per unit time or in other words the work done by any electrical appliance per unit time. Power is expressed as -
P = E/T where E is Energy and T is the time period.
How to calculate the value of power in the question ?Given that the light bulb emits 30 J light energy in 2 seconds.
We have E = 30J and T = 2 seconds.
Therefore power(P) = Energy(E) / Time(T)
∴ P = 30 / 2 = 15 watts
Thus the power of the light bulb is 15 watts.

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
Answers
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
Based on the law of conservation of energy hiw can we reasonably improve a machines ability to do work

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.

B.

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.
Answers
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.
