Maggie completed a 10000-m race at an average speed of 160
m/min. If Tom took 12.5 fewer minutes to complete the race,
what was Tom's average speed?
Answers
Answer:
200m/minExplanation:
The formula for calculating distance covered = Speed * time
If Maggie completed a 10000-m race at an average speed of 160
m/min, the the time taken by Maggie to complete the race will be expressed as;
Time = Distance/Speed
Time = 10000/160
Time = 62.5 minutes
If it took Tom 12.5 fewer minutes to complete the race, then the time taken by tom to finish the same race will be 62.5 - 12.5 = 50minutes.
To get Tom's average speed, we will use the same formula as above;
From Distance = Speed * Time
Speed = Distance/Time
Since both of them completed the same distance, distance covered by Tom is also 10000m
Tom's speed = 10000/50
Tom's speed = 200m/min
Hence Tom's average speed is 200m/min

A negatively-charged ion always has more neutrons than protons
A negatively-charged ion always has more electrons than protons
A negatively-charged ion always has more protons than electrons
A negatively-charged ion always has more protons than neutrons
Answers
Answer: A negatively-charged ion always has more electrons than protons
Explanation:
First, we know that the elementary negative charge is the electron, while the positive one is the proton. Such that both have the same charge in magnitude, but a different sign. Such that if we have the same number of electrons and protons in an atom, the charge of this atom will be neutral.
And an ion is an atom with a different number of electrons and protons, so the charge of the atom is not neutral.
Then if we have a negatively-charged ion, the charge of this atom is negative. Then we must have a larger number of electrons (the negative ones) than protons (the positive ones)
Then the correct option is:
A negatively-charged ion always has more electrons than protons

what average force, in newtons, was exerted to slow him if he was moving horizontally? (the gravitational force is balanced by the buoyant force of the water.)
Answers
The average force that was exerted to slow the object is 0 N.
To find the average force that was exerted to slow the object, we can use the formula:
F = mΔv / Δt
Where:
F = force (in Newtons)
m = mass (in kilograms)
Δv = change in velocity (in meters per second)
Δt = change in time (in seconds)
Given that the gravitational force is balanced by the buoyant force of the water, the net force on the object is zero. This means that the average force exerted to slow the object is also zero.
Therefore:

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?
Answers
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.

Calculate the acceleration due to gravity on the surface of the Sun.
Answers
The acceleration due to gravity on the surface of the Sun is approximately 274 m/s² (meters per second squared).
The acceleration due to gravity is a measure of the gravitational force experienced by an object near the surface of a celestial body. It is calculated using Newton's law of universal gravitation:
acceleration due to gravity (g) = GM / R²,
where G is the gravitational constant, M is the mass of the celestial body, and R is the distance from the center of the celestial body to the object.
Given that we want to calculate the acceleration due to gravity on the surface of the Sun, we can use the following values:
Mass of the Sun (M) = 1.989 × 10^30 kg
Radius of the Sun (R) = 6.9634 × 10^8 meters (approximately)
Gravitational constant (G) = 6.67430 × 10^(-11) N(m/kg)²
Substituting the values into the formula:
g = (6.67430 × 10^(-11) N(m/kg)² * 1.989 × 10^30 kg) / (6.9634 × 10^8 meters)²
= (1.3271247 × 10^20 N(m/kg)²) / (4.8557736 × 10^17 meters²)
≈ 2.7435 × 10² m/s²
≈ 274 m/s² (rounded to three significant figures)
Therefore, the acceleration due to gravity on the surface of the Sun is approximately 274 m/s².
The acceleration due to gravity on the surface of the Sun is approximately 274 m/s². This calculation is based on the gravitational constant, the mass of the Sun, and the radius of the Sun, as per Newton's law of universal gravitation.

We determine the maximum magnitude of the acceleration of the rider by using the maximum force, that is:
\(F=m\cdot a\Rightarrow1.20N=a=\frac{1.20N}{m}\)So, the maixmum magnitude of the acceleration will depend on the mass of the rider. Now, since the mass cannot be 0 kg since that would undetermine the expression we know then that the best approximation is:

To which of the following quantities, the radius of the circular path of a charged particle moving at right angles to a uniform magnetic field is directly proportional?
Answers
The radius of the circular path of a charged particle moving at right angles to a uniform magnetic field is directly proportional to the magnitude of the particle's momentum.
Hence, the correct option is D.
The radius of the circular path of a charged particle moving at right angles to a uniform magnetic field is directly proportional to the magnitude of the particle's momentum.
Mathematically, we can express this relationship as:
r ∝ p
Where:
r is the radius of the circular path,
p is the momentum of the charged particle.
This relationship can be derived from the equation for the centripetal force experienced by a charged particle moving in a magnetic field, given by:
F = qvB
where:
F is the centripetal force,
q is the charge of the particle,
v is the velocity of the particle,
B is the magnitude of the magnetic field.
Since the centripetal force is also equal to mv²/r, where m is the mass of the particle, we can equate these two expressions:
mv²/r = qvB
Simplifying the equation, we find:
mv = qBr
From this equation, we see that the radius of the circular path (r) is directly proportional to the momentum of the charged particle (mv), which is a product of the mass and velocity.
Hence, the correct option is D.
The given question is incomplete and the complete question is '' To which of the following quantities, the radius of the circular path of a charged particle moving at right angles to a uniform magnetic field is directly proportional ?

Answers
Hence, the acceleration will be 16 m/s²
According to Newton's second law of motion, acceleration of an object is directly proportional to the net force acting on it keeping the mass of the object constant.
Mathematically,
F ∝ a
It means that when there is no net force acting on the body, there is no acceleration. A force is a push or a pull, and the net force ΣF is the total force, or sum of the forces exerted on an object in all directions. When the net force is increased or decreased by a factor of X, then acceleration also increased or decreased by a factor of X respectively according to Newton's 2nd law of motion.

The bearing of grids of an AB alignment is 100º 22', while the magnetic declination is 8º30' E. What are the true azimuth, magnetic azimuth, and grid azimuth of this alignment?
Answers
The true azimuth of the AB alignment is 91º 52' (east of north), the magnetic azimuth is 100º 22' (east of north), and the grid azimuth is 108º 52' (east of north).
To find the true azimuth, magnetic azimuth, and grid azimuth of the AB alignment, we need to consider the magnetic declination. The magnetic declination indicates the angle between true north and magnetic north at a specific location. In this case, the magnetic declination is 8º 30' E, which means that the magnetic north is 8º 30' east of the true north.
To calculate the true azimuth, we subtract the magnetic declination from the grid azimuth. The grid azimuth is given as 100º 22', so subtracting the magnetic declination of 8º 30' E gives us a true azimuth of 91º 52' (east of north).
The magnetic azimuth remains the same as the grid azimuth, which is 100º 22' (east of north).
The grid azimuth is calculated by adding the magnetic declination to the true azimuth. Since the magnetic declination is east, we add it to the true azimuth. Adding 8º 30' E to the true azimuth of 91º 52' gives us a grid azimuth of 108º 52' (east of north).
