Two 100-newton weights are attached to a tension scale, one on each side. What does the scale read?
The scale will read 200 newtons when two 100-newton weights are attached to it.
In this case, there are two 100-newton weights attached to the scale, one on each side. The weight is a force acting downwards due to gravity.
Since there are two 100-newton weights, the total force acting downwards is 100 newtons + 100 newtons = 200 newtons.
According to Newton's third law, the scale will exert an equal and opposite force, known as tension, to counterbalance the weights. Therefore, the scale will read the tension force exerted by the weights.
In this scenario, the scale will read 200 newtons. This is because the scale needs to exert a force of 200 newtons upwards to counterbalance the two 100-newton weights acting downwards.
So, the scale will read 200 newtons when two 100-newton weights are attached to it.

sbj’s austin karp discovered which non-football sports event achieved the highest viewership in q1?
The non-football sports event that achieved the highest viewership, as discovered by Austin Karp of Sports Business Journal (SBJ), was the NCAA Men's Basketball Tournament, also known as March Madness.
This annual event features 68 college basketball teams competing in a single-elimination tournament to determine the national champion. The tournament is organized by the National Collegiate Athletic Association (NCAA) and typically takes place in March and April, hence its popular nickname.
March Madness garners significant attention from sports enthusiasts, attracting millions of viewers and generating substantial revenue through television contracts, ticket sales, and sponsorship deals. The excitement surrounding the tournament is fueled by the intense competition, thrilling finishes, and the unpredictability of the outcomes, as lower-seeded teams often upset higher-seeded opponents.
In addition, many fans participate in "bracket challenges," attempting to predict the winners of each game and ultimately, the tournament champion.
The high viewership of the NCAA Men's Basketball Tournament can be attributed to various factors, such as the passion of college sports fans, the wide range of participating schools, and the engaging format of the event.
Consequently, March Madness has become one of the most-watched sporting events in the United States, surpassing other non-football sports events in terms of viewership during the first quarter of the year.

The activation energy of a certain reaction is 47.1kJ/mol . At 20C , the rate constant is 0.0170s^{-1} . At what temperature in degrees Celsius would this reaction go twice as fast? Given that the initial rate constant is 0.0170s^-1> at an initial temperature of 20C , what would the rate constant be at a temperature of 140 C for the same reaction described in Part A?
The activation energy of a certain reaction is used to find the temperature at which the reaction would go twice as fast. while the Arrhenius equation can be used to find the rate constant at a different temperature for the same reaction.
We can use the Arrhenius equation, which relates the rate constant of a reaction to the activation energy and temperature. We know the rate constant at 20C and the activation energy, so we can set up the equation as follows:
k2 = 2k1
ln(k2/k1) = Ea/R * (1/T1 - 1/T2)
T2 = Ea/R * (1/T1 - ln(k2/k1)/Ea)
Plugging in the given values, we get:
T2 = 47.1 kJ/mol / (8.314 J/mol*K) * (1/293 K - ln(2)/(47.1 kJ/mol))
T2 ≈ 358 K or 85 C
For the second part of your question, we can use the same equation to find the rate constant at 140 C:
ln(k2/k1) = Ea/R * (1/T1 - 1/T2)
k2 = k1 * e^(Ea/R * (1/T1 - 1/T2))
Plugging in the given values, we get:
k2 = 0.0170 s^-1 * e^(47.1 kJ/mol / (8.314 J/mol*K) * (1/293 K - 1/413 K))
k2 ≈ 1.81 s^-1.

an air mass near the surface of the earth has a temperature of 27 degrees celsius. what is the dew point temperature of this air mass near the surface of the earth if the condensation level for clouds was observed at 3000 meters?
The dew point temperature of the air mass near the surface of the earth is approximately 27 degrees Celsius, assuming that the relative humidity is 100% at the condensation level of 3000 meters.
Firstly, let me explain what dew point temperature is. Dew point temperature is the temperature at which the air becomes saturated with water vapor, and condensation occurs. In other words, it is the temperature at which dew or frost forms on the ground or other surfaces.
Now, let's consider the given information. We know that the air mass near the surface of the earth has a temperature of 27 degrees Celsius. We also know that the condensation level for clouds was observed at 3000 meters.
The condensation level is the altitude at which the relative humidity of the air reaches 100%, and the water vapor in the air begins to condense into visible water droplets or ice crystals, forming clouds.
To find the dew point temperature, we need to calculate the relative humidity of the air at the condensation level. The relative humidity is the amount of water vapor in the air compared to the amount of water vapor that the air can hold at a given temperature.
The formula to calculate relative humidity is:
RH = (actual vapor pressure / saturation vapor pressure) x 100
Where RH is relative humidity, actual vapor pressure is the pressure exerted by the water vapor in the air, and saturation vapor pressure is the maximum pressure that the water vapor in the air can exert at a given temperature.
To find the saturation vapor pressure, we can use the Magnus formula:
es = 6.11 x 10^(7.5T / (237.3 + T))
Where es is the saturation vapor pressure in Pascals, and T is the temperature in degrees Celsius.
Using this formula, we can find that the saturation vapor pressure at 27 degrees Celsius is approximately 3192 Pa.
Now, we need to find the actual vapor pressure at the condensation level, which is also known as the vapor pressure deficit. To do this, we can use the following formula:
VPD = es - e
Where VPD is the vapor pressure deficit, es is the saturation vapor pressure at the given temperature, and e is the actual vapor pressure.
Since the relative humidity at the condensation level is 100%, we know that the actual vapor pressure is equal to the saturation vapor pressure, which is 3192 Pa.
So, the vapor pressure deficit is 0 Pa, and the relative humidity is 100% at the condensation level.
To find the dew point temperature, we can use a dew point calculator or a psychrometric chart. According to a typical psychrometric chart, the dew point temperature for an air mass with a relative humidity of 100% at 27 degrees Celsius is approximately 27 degrees Celsius.

This is also one I am confused on
The speakers in a sports stadium are 89. 5 m from a fan's seat. It takes approximately 0.261 seconds for sound to travel from the speakers to the fan's seat in the sports stadium.
The time it takes for sound to travel from the speakers to the fan's seat can be calculated using the formula
Time = distance / speed
Where distance is the distance between the speakers and the fan's seat, and speed is the speed of sound in air.
In this case, the distance between the speakers and the fan's seat is 89.5 m, and the speed of sound in air is 343 m/s (at standard temperature and pressure).
Plugging in these values into the formula, we get
Time = 89.5 m / 343 m/s

a 100-n force and a 50-n force on p. the 100n force acts due north. What is the mantitude and direction of resulant force
The given forces are a 100 N force and a 50 N force acting on point P. The 100 N force acts due north. We have to calculate the magnitude and direction of the resultant force. Use vector addition to find the resultant force, we can use the Pythagorean theorem. The magnitude of the resultant force is 111.8 N (approximately)
We haveF1 = 100N force acting due north.F2 = 50N force acting at an unknown direction
Therefore, Resulant force, F = √(F1² + F2²) Resulant force, F = √(100² + 50²) Resulant force, F = √10000 + 2500Resulant force, F = √12500Resulant force, F = 111.8 N (approximately)Now, we can use trigonometry to find the direction of the resultant force. We can find the angle using sine and cosine functions.
We have the angle that the resultant force makes with the north direction as follows; sin(θ) = opposite/hypotenuse = F2/Fcos(θ) = adjacent/hypotenuse = F1/F Solving for θ, we get;θ = tan⁻¹(F2/F1)θ = tan⁻¹(50/100)θ = tan⁻¹(0.5)θ = 26.57°
Hence, the magnitude of the resultant force is 111.8 N (approximately) and the direction of the resultant force makes an angle of 26.57° with the north direction.

When a 5 kg rock is dropped from a height of 6 m on Planet X, it loses 24 J of GPE. What is the acceleration due to gravity on Planet X?
Answer:
g = 1.25m/s²
Explanation:
Given the following data;
Mass = 5kg
Height = 6m
Gravitational potential energy = 24J
To find the acceleration due to gravity;
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;
\( P.E = mgh\)
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.
GPE = mgh
Substituting into the equation, we have;
24 = 5*6*g
24 = 30g
g = 30/24
g = 1.25m/s²
Therefore, the acceleration due to gravity on Planet X is 1.25m/s².
Answer:
g=0.8m/s^2
Explanation:
M=5kg
h=6m
GPE=24J
GPE=Mgh
g=GPE/Mh
g=24J/(5kg)(6m)=0.8
g=0.8m/s^2
