The velocity of the vehicle is equal to 406.5 m/s. The velocity in Km/hr is 1463.4 Km/hr.
What is the velocity?Velocity can be demonstrated as a vector measurement of the direction of the object and the rate of motion of an object. The velocity of an object can be described as the change in the body's position w.r.t. time.
Velocity can be expressed as a vector quantity as it consists of magnitude as well as direction. A mathematical formula common and simplest way to find velocity.
v = d / t
Where v is the velocity, d is the distance covered and t is the time taken by the body.
The S.I. unit for velocity can be represented as m/s and can be expressed in terms of miles per hour (mph), and kilometers per hour (kph).
Given, the distance traveled by the vehicle, d = 100 m
The time taken by vehicle = 0.246 sec
The velocity of the vehicle, v = 100/0.246 = 406.5 m/s
We know that 1km = 1000m then 1 m = 10⁻³ Km
1 hour = 60 ×60 = 3600 s
1s = 1/3600 hr
Therefore, velocity, \(\displaystyle v = 406.5 \times \frac{3600}{1000} Km/hr\)
v = 1463.4 Km/hr

Velocity = Distance / Time = 100 m / 0.246 s = 406.50 m/s
To convert m/s to km/hr, we need to multiply the velocity by 3.6:
Velocity in km/hr = Velocity in m/s x 3.6 = 406.50 m/s x 3.6 = 1463.80 km/hr
The steps I took to convert from m/s to km/hr were to multiply the velocity in m/s by 3.6, which is the conversion factor between meters per second and kilometers per hour.
Explain what happens as the heart grows bigger.
Answers
Initially, the heart may grow bigger as a compensatory mechanism to try to keep up with increased demands for blood and oxygen. For example, if a person engages in regular exercise, their heart may enlarge to accommodate the increased demand for blood and oxygen to the muscles.
However, if the heart continues to grow over time, it can become less efficient at pumping blood and may develop structural abnormalities that increase the risk of heart failure, arrhythmias, and other complications.
In some cases, cardiac hypertrophy may be reversible if the underlying cause is treated, such as by managing high blood pressure or heart disease. However, if left untreated, hypertrophy can lead to irreversible damage to the heart muscle and may require more aggressive interventions, such as medication, surgery, or other medical procedures to manage the condition.

The air currents across the continents would determine the distribution of the air.
What are air currents?Air currents across the continents are primarily driven by temperature differences and the rotation of the Earth. The warm air near the equator rises and flows towards the poles, while the cooler air near the poles sinks and flows towards the equator.
This creates large-scale circulation patterns known as Hadley cells, Ferrell cells, and Polar cells. These cells are responsible for the trade winds, westerlies, and easterlies, respectively. Additionally, there are also local winds caused by differences in terrain, such as sea breezes and valley breezes.

What would happen to the digestion process if enzymes were not present
Answers
Answer: It would take 2.3 billion years for the biological reaction without the presence of enzymes. It’s because, without them, your body can’t break down foods so that nutrients can be fully absorbed. Every organ, every tissue, and every 100 trillion cells in our body rely upon the reaction of metabolic enzymes and their energy component.
Explanation:
I hope this helps
Without enzymes, the body would not be able to break down complex carbohydrates, proteins, and fats into their component molecules. This means that these nutrients would not be absorbed by the body and would be excreted as waste.
Additionally, the lack of enzymes would make it difficult for the body to digest and absorb vitamins and minerals. This could lead to malnutrition and other health problems over time.
Overall, the absence of enzymes from the digestive process would severely impair the body's ability to extract nutrients from food and could have negative consequences for overall health and well-being.
The work input = _____.
F i ÷ d i
F o ÷ d o
F o × d o
F i × d i
Answers
The work input = Fi × di
How to solve for work input?To solve for work input, you need to know the force acting on an object and the distance it moves in the direction of the force. Work input is defined as the product of force and distance, given by the formula:
Work Input = Force × Distance × cosθ
Where θ is the angle between the force vector and the direction of motion. If the force is applied in the direction of motion, then θ = 0 and cosθ = 1, so the formula simplifies to:
Work Input = Force × Distance
For example, if you are pushing a box with a force of 50 newtons over a distance of 10 meters, the work input would be:
Work Input = 50 N × 10 m × cos(0°) = 500 Joules

The average speed of the blocks are 0.36 m/S.
Explanation:
Average speed is defined as the ratio of distance covered per unit time. So if it is said that blocks are pulled to 0.9 m in the right side. This means the blocks cover a distance of 0.9 m from the origin and that distance is covered in 2.5 s. Thus, the average speed can be calculated from the change in speed
with respect to time. As at time t = 0, the speed is
also zero, and at time t = 2.5 s, the speed will be
Speed =
0.9 = 0.36
2.5
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.

Use the data in the table to explain how you could determine the volume of the block.
Answers
To find the volume of the block, subtract the initial water volume from the final water volume, convert the change in water volume to cubic centimeters, and consider it as the volume of the block.
To find the volume of the block using the measurements provided.
1. Calculate the change in water volume:
The initial water volume is given as 62.3 mL, and the final water volume is given as 89.5 mL. To determine the change in water volume, we subtract the initial volume from the final volume: 89.5 mL - 62.3 mL = 27.2 mL. This value represents the increase in water volume caused by placing the block in the graduated cylinder.
2. Convert the change in water volume to cubic centimeters:
Since 1 mL is equivalent to 1 cubic centimeter (cc), we can directly convert the change in water volume from milliliters to cubic centimeters. In this case, the change in water volume is 27.2 mL, which is also equal to 27.2 cc.
3. Determine the volume of the block:
When the block is placed in the graduated cylinder, it displaces some amount of water, resulting in an increase in water volume. By measuring this increase in volume, we can determine the volume of the block itself. In this case, the change in water volume of 27.2 cc represents the volume of the block.
By following these steps, we can find the volume of the block based on the provided measurements.
Therefore, By deducting the initial water volume from the final water volume and converting the difference in water volume to cubic centimeters, the block's volume can be calculated. the volume of the block is 27.2 cc.
