Elite runners follow a rigid training schedule that gradually increases their capacity for the longer distances. Additionally, they run regularly (often 5 to 6 times per week). On the other hand, the typical runner might run significantly more when the weather is favorable or when they have more time.
What are the elite runners will train with a speed chute?Running speed is influenced by stride cadence and stride length. The number of steps made in a second is referred to as the stride cadence, and the distance covered by each step is referred to as the stride length.
Therefore, running speed can be mathematically described using the product of these variables.

what is the voltage of a toaster oven if it has a resistance of 735 ohms and a has current of 0.63 amps?
The voltage of a toaster oven is 463.05 volt.
What is Ohm's law?Under the assumption that all physical parameters and temperatures remain constant, Ohm's law asserts that the voltage across a conductor is directly proportional to the current flowing through it.
This current-voltage relationship is expressed mathematically as:
V = IR
Given that: resistance of the toaster oven : r = 735 ohm.
Current flowing through it: I = 0.63 Ampere.
Hence, potential drop across the toaster oven : V = IR

The (Figure 1) shows two thin beams joined at right angles. The verticalbeam is 12.0kg and 1.00 m long and the horizontal beam is 26.0kg and 2.00 m long. Neglect the lateral dimensions of the beams.1)Find the center of gravity of the two joined beams. Express your answer in the form x,y, taking the origin at the corner where the beams join.2)Calculate the gravitational torque on the joined beams about an axis through the corner
A) The center of the gravity of the two joined beams is;
(x, y) = (25/44), (19/88)
B) The gravitational torque on joined beams about an axis through the corner is;
τ = 245 N.m
How to calculate the gravitational torque on the joined beams about an axis through the corner?We have;
Mass of the vertical beam; m₂ = 19 kg
Mass of the horizontal beam, m₁ = 25 kg
Length of the horizontal beam; L₁ = 2 m
Length of the vertical beam; L₂ = 1 m
A) The formula for the center of gravity of the two joined beams is;

The period of oscillation is 4.44 s
What is the period of oscillation?The period of oscillation is the time it takes the spring to complete one cycle of motion.
How to find the period of oscillation of the spring using energy?Using the law of conservation of energy, the total mechanical energy at the origin (x = 0) equals the total mechanical energy at maximum displacement (x = A).
Since
the potential energy of the mass is U = kx⁴ and the kinetic energy of the mass K = 1/2mω(A² - x²) where k = positive constant = 1, m = mass of object = 1ω = angular speed of object = 2π/T where T = period of oscillationA = maximum displacement of mass = 1 and x = displacement of massSo, U₁ + K₁ = U₂ + K₂ where
U₁ = potential energy at (x = 0) = 0 (since there is no displacement, K₁ = kinetic energy at (x = 0) = 1/2mω(A² - x²) = 1/2mω(A² - 0²) = 1/2mω²A² = 1/2m(2π/T)²A² = 2m(π/T)²A² ,U₂ = potential energy at (x = A) = kA⁴ and K₂ = kinetic energy at (x = A) = 0 J (since it is stationary here)So, substituting the values of the variables into the equation, we have
U₁ + K₁ = U₂ + K₂
0 + 2m(π/T)²A² = kA⁴ + 0
2m(π/T)²A² = kA⁴
2m(π/T)² = kA²
Making T subject of the formula, we have
T² = 2mπ²/kA²
T = π/A√(2m/k)
Since m = k = A = 1, we have that the period of oscillation is
T = π/A√(2m/k)
T = π/1√(2 × 1/1)
T = π√2
T = 1.4142π
T = 4.443 s
T ≅ 4.44 s
So, the period is 4.44 s

What are spheres?
A sphere is a geometrical object that is a three-dimensional analog to a two-dimensional circle. A sphere is a set of points that are all at the same distance r from a given point in three-dimensional space. That given point is the center of the sphere, and r is the sphere's radius.

a) The acceleration of a body along an inclined for rolling without slipping is given by -
[tex]a = \frac{ g sin \theta}{1 + \frac{I}{mR^{2} } }[/tex]
For Spheres, I = 2/5 mR²
[tex]a_{A} = \frac{ g sin \theta}{1 + \frac{2}{5}mR^{2} } } =\frac{5g sin \theta}{7}[/tex]
[tex]a_{B} = \frac{g sin \theta}{1 + \frac{\frac{2}{5}(2m)(2R^{2} ) }{(2m)(2R^{2} )} } = \frac{5g sin \theta}{7}[/tex]
[tex]a_{C} = \frac{g sin \theta}{1 + \frac{\frac{2}{5}(m)(2R^{2} ) }{(m)(2R^{2} )} } = \frac{5g sin \theta}{7}[/tex]

problem 12.21 redo problem 12.20 using vesics methods assuming that skin friction is distributed uniformly along the shaft.
Using vedic math method assuming that skin friction is distributed uniformly along the shaft the correct anwer is 264.
Step 1: 1 * 4 = 4 (last digit)
Step 2: 4 * 1 + 1 * 2 = 6
Step 3: 1 * 2 = 2 (first digit)
Therefore, the correct answer using vedic math in this question is 264.
What do you mean by vedic maths?
Vedic mathematics is a system of mathematics discovered by the Indian mathematician Jagadguru Shri Bharathi Krishna Tirthaji between 1911 and 1918 and published his findings in the Vedic Mathematics Book by Tirthaji Maharaj.Solving problems using regular mathematical steps is sometimes difficult and time-consuming. But with Vedic Mathematic's general techniques (applicable to all given data sets) and Specific Techniques (applicable to specific given data sets) numerical calculations can be done very quickly.To know more about the start of vedic maths, click the link given below:

an force of 10 newtons acts on a 20 kilogram mass. the acceleration of the mass is question 13 options: 2m/s^2 1m/s^2 0.5m/s^2 200m/s^2
The change in momentum ΔP is 100kgm/s
What are newton's laws of motion?
Newton's laws of motion are three basic laws of classical mechanics that describe the relationship between the motion of an object and the forces acting on it. These laws can be paraphrased as follows: A body remains at rest, or in motion at a constant speed in a straight line, unless acted upon by a force.
Applying Newton's second law
∑F=ma
⇒F=ma
⇒10(N)=20(kg) a
⇒a=0.5m/s^2
Step 2: Final speed
Since acceleration is constant,
∴ Applying the equation of motion
v=u+at
u= Initial speed =0
v= Final speed
v=0+0.5(m/s^2 )×10(s)
=5m/s
Step 3: Change in momentum ΔP
ΔP=m(v−u)
=20(5−0)kgm/s
=100kgm/s

What is comet?
The comets' nuclei have a range of 100 m to 40 km acros. They are made up of frozen gases such carbon monoxide, carbon dioxide, methane, and ammonia as well as rock, dust, water ice, and frozen liquids.
What is Oort cloud ?
The Oort Cloud is thought to be a huge spherical shell that surrounds the Sun, planets, and Kuiper Belt Objects while the orbits of our solar system's planets are flat and level. The icy, comet-like particles form something resembling a large, thick bubble around our solar system.
Therefore, about a trillion comets are thought to be located far, far beyond Pluto in the blank is Oort cloud.

If you drive west at 40 mph for 25 hours how far would you travel?
Answer:
1000
Explanation:
25x40=1000
Answer:
If you drive west at 40 miles per hour for 25 hours, you would travel 1000 miles.
Explanation:
This is determined by multiplying the speed you are traveling (40 miles per hour) by the amount of time you are traveling (25 hours), which gives you 1000 miles. It's important to note that this is only an estimate, as various factors such as traffic and road conditions can affect your actual travel distance. Additionally, driving for extended periods of time can be dangerous, so it's important to take regular breaks and make sure you're well rested before getting behind the wheel.
