Answer: Baltimore
Explanation:
There is no diagram included but the answer can be inferred from the rotation of the Earth.
The Earth rotates from east to west which is why places further to the east receive sunlight first each day. It is for this reason that Australia and New Zealand receive sunlight more than 15 hours before the United States does.
In the U.S. the furthest city to the east mentioned in the options is Baltimore. They will therefore receive sunlight before everyone else.

Which form of electromagnetic radiation with a relatively high amount of energy is used to sanitize lab goggles?
Answer:
Gamma radiation.
Explanation:
Electromagnetic waves are waves produced with respect to the interaction of electric field and magnetic field. They can be arranged with respect to their increasing or decreasing wavelength to form a pattern called electromagnetic spectrum.
Gamma radiation can be used for sterilization purpose due to the fact that it has a relatively high amount of energy, and do not produce any characteristic radiation.

on what mass will a force 16N produce an acceleration of 160N
Answer:
m = 0.1 [kg]
Explanation:
To solve this problem we must use Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration. In this way, we have the following equation.
[tex]F =m*a[/tex]
where:
F = force = 16[N]
a = acceleration = 160 [m/s²]
m = mass [kg]
Now replacing:
[tex]m=F/a\\m = 16/160\\m = 0.1 [kg][/tex]

if a 50.0-kg mass weighs 554 n on the planet saturn, calculate saturn’s radius
Answer:
17.35 × 10^(-6) m
Explanation:
Mass; m = 50 kg
Weight; W = 554 N
Now, we know that;
W = mg
Thus; 554 = 50g
g = 554/50
g = 11.08 m/s²
Also, we know that;
mg = GMm/r²
g = GM/r²
Making t the subject gives;
r = √(GM/g)
G has a constant value of 6.67 × 10^(-11) Nm²/kg²
r = √(6.67 × 10^(-11) × 50/11.08)
r = 17.35 × 10^(-6) m
The radius of the saturn is [tex]\bold {17.35 x 10^{-6 }m}[/tex] if a 50.0-kg mass weighs 554 N.
From Newton's second law,
W = mg
554 = 50 x g
g = 554/50
g = 11.08 m/s²
Now, Newton's law of gravitation
[tex]\bold {F=G{\dfrac{m_1m_2}{r^2}}}[/tex]
Where,
F = force
G = gravitational constant = 6.67 x 10^-11 N.m²/kg²
m1 & m2= mass = M = 50 kg
r = distance between centers of the masses
Put the values and solve it for r,
[tex]\bold {r = \sqrt {(6.67 x10^{-11} \times \dfrac {50}{11.08}}}\\\\\bold {r = 17.35 x 10^{-6 }m}[/tex]
Therefore, the radius of the saturn is [tex]\bold {17.35 x 10^{-6 }m}[/tex] if a 50.0-kg mass weighs 554 N.

Explanation:
A 40-kg person is climbing 3 m up a flight of stairs in 6 seconds. How much work did they do climbing the stairs? answer choices . 400 J. 1200 J. 200 J. 120 J. Tags: Question 13 . SURVEY . 30 seconds . Report an issue . Q. A 40-kg person is climbing 3 m up a flight of stairs in 6 seconds. How much power did they exert climbing the stairs? answer choices . 400 W. 1200 W. 200 W. 120 W. Tags
200 W was used in climbing the stairs.
We'll begin by calculating the energy. This can be obtained as follow:
Mass (m) = 40 kg
Height (h) = 3 m
Acceleration due to gravity (g) = 10 m/s²
Energy (E) =? E = mghE = 40 × 10 × 3
E = 1200 JFinally, we shall determine the power exert in climbing the stairs. This can be obtained as follow:
Energy (E) = 1200 J
Time (t) = 6 s
Power (P) =?[tex]Power = \frac{Energy }{Time}\\\\Power = \frac{1200}{6}[/tex]
Power = 200 WThus, 200 W was used in climbing the stairs.

If the Earth did not have internal energy, which of the following carbon cycle process would not be possible?
burning fossil fuels
consumption
respiration
rock formation
Answer:
Rock Formation
Explanation:
If Earth did not have internal energy, the carbon cycle process that would not be possible is rock formation. So, the correct option is D.
What is Carbon cycle?The carbon cycle is described as a series of biogeochemical processes through which atoms of carbon or carbon compounds are fixed and utilized within the environment, moving carbon from the atmosphere to the Earth and back against which is carried into the atmosphere.
The main processes associated with carbon cycle include the following:
Respiration.Consumption.Combustion such as burning of fossil fuels.Rock formation.The formation of rock requires only that the Earth have enough internal energy to cause the movement of material around the core and mantle to cause slow but significant changes within the Earth's crust.
Therefore, the correct option is D

Question 4 options: The steps that lead you from dependence to independence are referred to as The _________ to Lifetime Fitness, Health, and Wellness.
Answer:
Stairway.
Explanation:
The steps that lead you from dependence to independence are referred to as the stairway to Lifetime Fitness, Health, and Wellness.
This ultimately implies that, these stairway or steps are very important and essential for all humans who seek Lifetime Fitness, Health, and Wellness.
A good health can be defined as the state of well-being (wellness) in which all of the components of an individual's health are balanced. These state of wellness comprises of six (6) important components and they are;
1. Physical: this is a measure of the state of an individual's body or the way the body functions. It is enhanced by eating right, working out or exercising, avoiding drugs and alcohol, maintaining a good body mass index etc.
2. Emotional: this deals with the state of an individual's mind being void of worries, negativity etc.
3. Social: this involves keeping a good relationship with friends, family and many others around.
4. Environmental: it deals with maintaining a hygienic surrounding, that is devoid of pollutants.
5. Mental or intellectual: avoiding unnecessary stress and anxiety while dealing or coping with the realities of life.
6. Spiritual: it encompasses belief systems, values, ideals, morality etc.
Hence, when an individual is able to balance all of these above mentioned components, then he or she is said to be healthy.

We are running late for school and we want to make our 0.5 kg tea (it’s at 90 C) colder. Let’s assume we can drink tea when it’s 50 C. We decided that it would be more convenient to drop an ice (0 C) since it will get cold soon. What mass of ice needs to be put in for this to happen?
Answer:
x=0.154kg
Explanation:
(x*L)+(0.5kg*4200*50)+(x*4200*(-50)=0
(x*333 000J/kg*c)+(0.5kg*4200J/kg*C*(-40C))+(x*4200J/kg*C*50C)=0

Light moves from flint glass (n = 1.66) into
water at an angle of incidence of 26.0°.
a) What is the angle of refraction?
Answer in units of º.
b) At what angle would the light have to be
incident to give an angle of refraction of 90.0°
Answer in units of º.
Explanation:
Through Snell's Law, we can solve this.
The formula is:
n1 * sin(theta1) = n2 * sin(theta2)
n1 = flint = 1.66
n2 = water = 1.33
theta1 = 26.0°
theta2 = angle of refraction
Substituting these values in the formula,
1.66 * sin(26) = 1.33 * sin(x)
[1.66 *sin(26)] ÷ 1.33 = sin( x )
0.5471 = sin(x)
arcsin(0.5471) = x
33.17 = x
Therefore, the angle of refraction is 33.17°
b.) Using the same formula, we have:
1.66 * sin(x) = 1.33 * sin(90)
sin(x) = [1.33 * sin(90)] ÷ 1.66
sin(x) = 0.8012
x = arcsin(0.8012)
x = 53.2453°
Therefore, the light needs to have an angle of incident of 53.2453° in order to have a 90° angle of refraction.

Famous French mathematician, physicist, and philosopher Blaise Pascal announced this law in the year 1647.
What is pascal law?According to this law, pressure applied to a liquid that is at rest is uniformly distributed throughout.
There are numerous uses for it in daily life. Numerous gadgets, like hydraulic lifts and brakes, are based on Pascal's law.
For incompressible fluids, Pascal's concept is applicable. The majority of vehicle repair shops using lifts use one common use. In essence, air from an air compressor is delivered to the top of oil in a container; the oil then exerts pressure on a sleeve or piston that raises the car.
Therefore, Famous French mathematician, physicist, and philosopher Blaise Pascal announced this law in the year 1647.

Two 5.0 kilogram objects have different gravitational potential energies. What property of the objects must differ?
Answer:
Height.
Explanation:
Potential energy can be defined as an energy possessed by an object or body due to its position.
Mathematically, potential energy is given by the formula;
[tex] P.E = mgh[/tex]
Where,
P.E represents potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per seconds square.
h represents the height measured in meters.
Hence, the property of the object (having a mass of 5 kilograms) which must differ to have different gravitational potential energies is the height from which they are falling from.
The object having the higher height would have a greater gravitational potential energy than the lower object.
