Force (F) = 5000N
[tex]Area = 200cm {}^{2} = 0.02m {}^{2} \\ Pressure = \frac{force}{area} \\ Pressure = \frac{5000}{0.02} \\ Pressure = 250000 \frac{n}{m {}^{2} } [/tex]
Is it possible for a fig with a mass of 0.04 kg to have a greater momentum than an elephant seal with a mass of 3,000 kg? Explain.
Yes, it is possible for a fig with a mass of 0.04 kg to have a greater momentum than an elephant seal with a mass of 3,000 kg.
What is momentum?The sum of an object's mass and velocity is termed as its momentum. It consists of both a magnitude and a direction, making it a vector quantity.
Reason for the above :For the given momentum K.E. is inversely proportional to the mass. Hence, the fig with a mass of 0.04 kg has lower kinetic energy. For two bodies having same kinetic energy, the lighter one has greater momentum.
Hence, Yes, it is possible for a fig with a mass of 0.04 kg to have a greater momentum than an elephant seal with a mass of 3,000 kg.

A student is connecting three resistors of various resistances together in a circuit. In one configuration, the resistors are connected in a series. In another configuration, the resistors are connected in parallel. Explain which configuration results in a higher total resistance.
The configuration with the resistors connected in series results in a higher total resistance.
What is the difference between a series and parallel circuit configuration?A series circuit configuration is one in which the electrical components are connected end-to-end, so that the current must flow through each component before reaching the next one. This means that the current is the same through all components, and the total resistance of the circuit is equal to the sum of the individual resistances. In contrast, a parallel circuit configuration is one in which the electrical components are connected side-by-side, so that the current can flow through multiple components at the same time. This means that the voltage across all components is the same, and the total resistance of the circuit is lower than the smallest individual resistance.

A figure skater begins spinning counterclock-
wise at an angular speed of 3.2 7 rad/s. Dur-
ing a 4.6 S interval, she slowly pulls her arms
inward and finally spins at 7.7 T rad/s.
3.
What is her average angular acceleration
during this time interval?
Answer in units of rad/s^2
According to the answer The average angular acceleration 1.3 rad/s^2.
What is angular acceleration?Angular acceleration is the rate of change of angular velocity over time. It is a vector quantity, which means that it has both a magnitude and direction. Angular acceleration is usually measured in units of radians per second squared (rad/s2). The magnitude of angular acceleration indicates how quickly the angular velocity is changing, and its direction indicates the direction of the angular velocity change.
The average angular acceleration of the figure skater during this time interval can be calculated using the equation a = (Δω)/(Δt). Here, Δω is the change in angular speed during the interval and Δt is the length of the interval.
Therefore, the average angular acceleration = (7.7 rad/s - 3.2 rad/s) / 4.6 s = 1.3 rad/s^2.

A race car sets out on a 100.0 km race. At the halfway marker, the pit crew notes that the driver has averaged only 80.0 km/h. What speed must the driver maintain for the second half of the race in order to average 100.0 km/h overall?
The driver has to maintain the speed of 133.3 km/h for second half of the race in order to average 100km/h.
What does "average velocity" and "speed" mean?In order to calculate average velocity, divide the change in position or displacement (x) by the time intervals (t) during which the displacement takes place. Depending on the displacement's sign, the average velocity can either be positive or negative. Meters per second (m/s or ms-1) is the SI measure for average velocity. By dividing the entire distance the body has traveled by the amount of time it took to cross that distance, the average speed formula can be calculated.
To complete the race in 1 hr => 100 km/hr in a 100 km
Driver is going 80 km/hr at half way marker (50m).
Time taken to cover 50m = 50 km * (1 hr/80 km) = 5/8 hour.
Total time to complete the race on average 100 km/hr is 1 hr.
Hence, time required to cover second half of the race => 1 hr - 5/8 hr
=> 3/8 hr
v= 50km/(3/8 hr) = 50*(8/3) = 133.3 km/h

What is nitrogen cycle?The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms. This process is essential for life on Earth, as nitrogen is a critical component of proteins, DNA, and other molecules that make up living organisms. The cycle is comprised of four main steps: nitrogen fixation, ammonification, nitrification, and denitrification. In the nitrogen fixation step, nitrogen gas from the atmosphere is converted into ammonia (NH3) or nitrogen oxide (NOx) molecules by certain bacteria and other organisms. In the ammonification step, organic nitrogen molecules are converted into ammonia. In the nitrification step, ammonia is converted into nitrate (NO3-) and nitrite (NO2-) molecules by bacteria. Lastly, in denitrification step, nitrate and nitrite are converted back into nitrogen gas by bacteria.

A girl run at 5m/ for 2 econd, then walk at 4m/ for 3econd, an ride bicycle at 10m/ for 5econd what i average peed of the girl for the entire trip?
Answer:
Explanation:
jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjkkkkkkkkkkkkkkkkiiiiiiiiiikooooooooooooop
To find the average speed of the girl for the entire trip, we need to calculate the total distance covered and the total time taken.
Distance covered during running = speed x time = 5 m/s x 2 s = 10 m
Distance covered during walking = speed x time = 4 m/s x 3 s = 12 m
Distance covered during biking = speed x time = 10 m/s x 5 s = 50 m
Total distance covered = 10 m + 12 m + 50 m = 72 m
Total time taken = 2 s + 3 s + 5 s = 10 s
Average speed = Total distance covered / Total time taken
= 72 m / 10 s
= 7.2 m/s
An electric penal sharpener is has a cument of 0.05A. The voltage is 6v. What is the resistance?
The total resistance in the circuit is 120 ohms
According to Ohm's law E= I*R
where E => Electromotive force that we know as Voltage
I refer to the Current in the circuit
From the given law, we can say that
voltage = current x resistance
so voltage in the circuit is 6v
and the current in the circuit is 0.05A
and resistance is x ohms
so
6= 0.05*xx= 6/0.05x = 120so the resistance in the circuit is 120 Ohms. The Current in the circuit is directly proportional to the voltage in the circuit at a constant resistance.

The wavelength of the radio wave is 5.5 × 10³ m. If the frequency of the wave is 5.5 × 10⁴ hertz and the speed of the wave is 3.0 × 10⁸ m/sec.
The speed(v) of a wave is the product of wavelength(λ) and the frequency(η). We can understand this relation by the definition of the speed, which is the distance travelled by the object in unit time. The unit of distance is meter, also the unit of the wavelength is meter. On the other hand the unit of frequency is sec⁻¹. So,
Speed of a wave(v) = wavelength(λ) × Frequency(η)
Wavelength(λ) = speed of the wave(v)/Frequency(η)
Wavelength(λ) = (3.0 × 10⁸)/(5.5 × 10⁴)

Could these mutations make the virus more deadly to humans? Support your answer in one or two sentences.
When SARS-CoV-2 replicates, mistakes can be made in some copies of its genome, giving rise to mutations. Mutations happen randomly and are a source of genetic variations, or differences, among viruses.
Yes, mutations in the SARS-Cov2 may make the virus more deadly to humans because they are selected to make the virus superior in an adaptive way in order to form the next generations of viruses.
What is the evolutionary meaning of genetic mutations in viruses and organisms?The evolutionary meaning of genetic mutations in viruses and organisms is based on the fact that mutation per se is not adaptive (or beneficial), deleterious or neutral, but it depends on the enviroment in which they are and how it affects the differential reproduction of the virus.
