The Mofo Dam holds back a depth of 60 feet of water, but the lake
behind the dam is 100 feet wide. The Fus-Ro-Dah Dam holds back a
depth of 50 feet of water, but the lake behind the dam is 2 miles wide.
If the dams are to be constructed in the same way, which dam had to
be constructed to be strongest? (The water levels do not vary
seasonally. )
Mathematically, the Mofo dam has a depth of 60 feet of water, and Fus-Ro-Dah Dam has a depth of 50 feet of water.
Hence, the Mofo dam is constructed to be the strongest.
What dam is constructed to be strongest?Question Parameters:
The Mofo Dam holds back a depth of 60 feet of water
The Fus-Ro-Dah Dam holds back a depth of 50 feet of water,
the lake behind the dam is 2 miles wide.
Generally, The main independent factor to be considered is the depth of a dam, as its the depth of water that applies the most pressure on dams, So the only effective factor is depth.
In conclusion, the Mofo dam because it holds back a depth of 60 feet of water, While the Fus-Ro-Dah Dam holds back a depth of 50 feet of water,

A post driver has a mass of 10kg. Calculate the change in GPE stored when the post driver is lifted by 50cm above the post. The gravitational field strength on earth is 10N/kg.
Answer:
500kJ
Explanation:
Common equation;
GPE = mgh
m = mass - in kg
g = gravitational field strength - in N/kg
h = height lifted/lowered - in meters
GPE = 10kg × 10N/kg × 5000m
GPE = 500000Nm
GPE = 500000J
GPE = 500kJ

In a parallel circuit, what’s happens to the current through each resistor when the voltage is doubled?
A. The current is doubled
B. The current is decreased by half
C. The current remains constant
Answer:
A
Explanation:
Voltage, V = Current, I x Resistance, R (V is directly proportional to I where R is constant of proportionality)
This means that when Voltage is increased, Current increases and when voltage is decreased, current decreases (and the inverse is true). Through all this though, resistance remains constant regardless.

An empty gas balloon has a mass of 500 kg. The balloon is filled with 3000m^3 of helium gas, at standard temperature and pressure (STP). If the densities of air and helium, at STP are 1.3kgm ^ - 3 and 0.18 kgm^ -3 respectively. Calculate the resultant force acting on the balloon. [g = 10N / Kg]
The resultant force acting on the balloon is 10,400 N.
Resultant force acting on the balloonThe resultant force acting on the balloon is calculated by applying Newton's second law of motion as follows;
F = ma
where;
m is massa is accelerationMass of the helium gas = density x volume
= 0.18 x 3000
= 540 kg
Total mass of the balloon = 500 kg + 540 kg = 1,040 kg
Resultant force = mg
Resultant force = 1040 x 10 = 10,400 N

what happens to heat energy after an object is cooled down lolololol asking for my bff
Answer:
Heat energy does not cool. Objects cool. Energy is not an object. Now, what happens when an object cools is that it gives off some of its thermal energy by one or more mechanisms: radiation, conduction, or convection. In radiation the energy escaped the object as electromagnetic waves - you see the red hot poker slowly dim as it cools, in conduction the energy is transferred Mechanically by the atoms of the hot object being in physical contact with those of the cool object and in convection the hot material moves to a cooler region where it gives up its heat energy by either radiation or conduction.

What does Einstein's famous equation for nuclear energy, E=mc2, mean?
Mass and energy are produced in a nuclear reaction.
Mass and energy are destroyed in a nuclear reaction.
Some mass and energy are lost in a nuclear reaction.
Some mass is converted into energy in a nuclear reaction.
Answer:
1.It's the world's most famous equation, but what does it really mean? "Energy equals mass times the speed of light squared." On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.
2.The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei.
3.In nuclear reactions, mass is never conserved—some mass is exchanged for energy and energy for mass. Nuclear reactions take place in an atom's nucleus. In a spontaneous nuclear reaction, such as radioactive decay, mass is "lost" and appears as energy in the form of particles or gamma rays.
4.In a nuclear reaction, mass decreases and energy increases. The sum of mass and energy is always conserved in a nuclear reaction.
5.The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei.

Hilda looks at a cd and sees different colors. Which best explains why she sees different colors when light strikes a cd?.
Answer:
The smooth surface of the CD causes wavelengths of light to scatter. The CD at this point acts somewhat like a prism splitting white light into the colors of the rainbow. This is called the visible spectrum of light and is composed of the colors red, orange, yellow, green, blue, indigo and violet.
Explanation:
Answer: The reflected wave has less energy
Explanation:
The incident wave would be the light wave before it comes in contact with the CD. Once the incident wave hits the CD, there is a reflected wave which will have some portion of energy from the incident wave. The reflected wave is a different color from the incident wave due to the reflected wave having less energy. Less energy means a different wavelength of visible light

Two technicians are discussing a resistance measurement between the can-h and can-l wires. Technician a says this measurement should be done with the ignition switch in the "run" position. Technician b states that a measurement of 0 ohms indicates an open in the network. Which technician is correct?
Based on the information given, the technician that's correct regarding the resistance measurement between the wires is Technician A.
Who is a technician?It should be noted that a technician simply means an individual that's in charge of looking after the technical equipment in an organization.
In this case, Technician A is correct. Technician B is incorrect as zero-ohm doesn't indicate an open circuit in the network but rather, a complete circuit.
