A baseball is thrown at a velocity of 98.4 miles per hour. what is the speed in m/s?
A baseball is thrown at a velocity of 98.4 miles per hour. The speed in m/s is approximately 43.73 m/s.
The velocity or speed means the amount of distance we have travelled per unit time.
The speed given is 98.4 miles/hour
V = 98.4 miles/hour
Since, 1 miles = 1.6 km = 1600 m
1 hour = 3600 s
So the speed in metre per second is:
V = [tex]\frac{98.4 \times 1600}{3600} m/s[/tex]
[tex]\approx 43.73 \ m/s[/tex]

Use the fundamental theorem of calculus.
[tex]\displaystyle \vec v(t) = \vec v(0) + \int_0^t \vec a(u) \, du[/tex]
[tex]\displaystyle \vec v(t) = \vec k + \int_0^t (6\,\vec\imath+6\,\vec\jmath) \, du[/tex]

[tex]\displaystyle \vec r(t) = \vec r(0) + \displaystyle \int_0^t \vec v(u) \, du[/tex]
[tex]\displaystyle \vec r(t) = \vec\imath + \displaystyle \int_0^t (6t\,\vec\imath + 6t\,\vec\jmath + \vec k) \, du[/tex]
[tex]\boxed{\vec r(t) = (3t^2 + 1)\,\vec\imath + 3t^2\,\vec\jmath + t\,\vec k}[/tex]
The velocity vector is v(t) = 6t i + 3t j + k, and the position vector is r(t) = [tex]\rm 3t^2 i + (3/2)t^2 j + kt + i.[/tex]
We have to integrate the specified acceleration vector to obtain the velocity vector of the particle before integrating the velocity vector to obtain the position vector of the particle.
So, the acceleration vector: a(t) = 6i + 3j
We will the find the velocity vector,
To find the velocity vector, we integrate the acceleration vector with respect to time 't':
∫a(t) dt = ∫(6i + 3j) dt
when we integrate with respect to time 't' that gives us:
v(t) = 6t i + 3t j + C
where 'C' is the constant of integration.
Using the initial velocity condition to find 'C':
Given initial velocity: v(0) = k
Substitute t = 0 into the velocity vector equation:
v(0) = 6(0) i + 3(0) j + C
k = C
So, C = k
We put the value of 'C' back into the velocity vector equation:
v(t) = 6t i + 3t j + k
Calculate the position vector r(t):
To find the position vector, we integrate the velocity vector with respect to time 't':
∫v(t) dt = ∫(6t i + 3t j + k) dt
Integrating with respect to time 't' gives us:
r(t) = [tex]\rm 3t^2 i + (3/2)t^2 j + kt + D[/tex]
where 'D' is the constant of integration.
We use the initial position condition to find 'D':
Given initial position: r(0) = i
Substitute t = 0 into the position vector equation:
r(0) = [tex]\rm 3(0)^2 i + (3/2)(0)^2 j[/tex]+ k(0) + D
i = D
So, D = i
when we put the value of 'D' back into the position vector equation:
r(t) = [tex]\rm 3t^2 i + (3/2)t^2 j + kt + i[/tex]
Therefore, the velocity vector is v(t) = 6t i + 3t j + k, and the position vector is r(t) = [tex]\rm 3t^2 i + (3/2)t^2 j + kt + i.[/tex]

Particle dislodgement in the filtration process is generally undesirable, except during?
Particle dislodgement in the filtration process is generally undesirable, except during high pressure jets of water applied to filter media during a backwash.
Define filtration process.Filtration is a physical separation procedure that uses a filter medium with a complicated structure that only allows fluid to pass through it to separate solid particles and liquid from a combination. Filtrate is the term for the liquid that passes through the filter medium and is used to describe solid particles that are too large to pass. Larger-than-average particles have the potential to blind the filter by blocking the filter lattice and forming a filter cake on top of the filter. The term "effective pore size" refers to the size of the biggest particles that may successfully pass through a filter.

A bullet brand unknown is fired from the feg p9r pistol. suppose the velocity (at 15 feet) of the bullet us 1,000 feet per second. is the bullet likely to be manufactured by winchester?
No, the bullet is not likely to be manufactured by Winchester.
Given:
X = 936
S=10\ss=10
We are unable to use the empirical rule since we do not know if the distribution is symmetric or skewed.
According to Chebyshev’s rule, which states that at least 89% of the data values are contained within 3 standard deviations of the mean, can be used to help us.
Overline x 3s=936 3(10) = 906 x 3s = 936 3(10) = 906
Overline x +2x = 936 + 3 (10), which becomes x +2x = 936
Thus, between 906 and 966 is the range for at least 89% of the velocities.
Empirical principle approximately 68.3 percent of the values in a data set with a symmetric distribution will be within one standard deviation of the mean, approximately 95.4 percent will be within two standard deviations of the mean, and approximately 99.7 percent will be within three standard deviations of the mean.
Usual values fall within 3 standard deviations of any mean and 1000 does not come within 3 standard deviations of the mean, thus it is unlikely that the bullet with velocity 1000 feet per second was manufactured by Winchester.

The pupil of a cat's eye narrows to a vertical slit of width 0. 500mm in daylight. Assume the average wavelength of the light is 500nm. What is the angular resolution for horizontally separated mice?
The angular resolution for horizontally separated mice is 1.00×10−3 rad
The Rayleigh criterion for the diffraction limit to resolution states “that two images are just resolvable when the center of the diffraction pattern of one is directly over the first minimum of the diffraction pattern of the other”. This criterion is based on the fact that Light diffracts as it moves through space, bending around obstacles, interfering constructively and destructively.
We assume Rayleigh's criterion applies to the cat's eye with pupil narrowed. For a single slit (not a round aperture), for small angles
θ ≈ sin θ =λ/a

Although originally designed to detect natural earthquakes, seismographs have a wide range of applications, including petroleum exploration, research into the Earth's crust and lower layers, and monitoring volcanic activity.
Seismographs are devices that record the movement of the ground during an earthquake. They are installed on the ground as part of a seismographic network all over the world.

Your weight is:__________
a. actually your mass.
b. the gravitational attraction between you and the earth.
c. a property of mechanical equilibrium.
d. the same in all locations.
Your body weight is the gravitational attraction between you and the Earth.
What is gravity?Gravity, which means "weight" in Latin, is a basic interaction in physics that causes all objects with mass or energy to attract one another. The electromagnetic force, the weak interaction, and the strong interaction are all significantly stronger than gravity, which is by far the weakest of the four fundamental interactions. As a result, it has no appreciable impact on subatomic particle level phenomena. On Earth, gravity imparts weight to tangible items, and the Moon's gravity creates tides in the oceans. However, gravity is the most important interaction between objects at the macroscopic scale, determining the motion of planets, stars, galaxies, and even light.

The average density of a planet is 1.52 g/cm3. what is its density in kg/m3? (enter your answer in scientific notation.)
Density is equal to the mass of substance divided by its volume.
What is density?Thickness is the substance's mass per unit of volume. The image most frequently utilized for thickness is ρ (the lower-case Greek letter rho), albeit the Latin letter D can likewise be utilized. Numerically, thickness is characterized as mass separated by volume: ρ=m/V where ρ is the thickness, m is the mass, and V is the volume. Now and again (for example, in the US oil and gas industry), thickness is approximately characterized as its weight per unit volume, albeit this is experimentally wrong this amount is all the more explicitly called explicit weight.

If the reaction is second order in a and first order in b, what is the rate when the initial concentration of [a] = 4.11 mol/l and that of [b] = 3.71 mol/l?
Answer:
New concentration of A =3 [A] Put the values we get new rate of reaction. − dtd[R]=k[3A] 2[B] Hence, the rate of reaction will increase by 9 times. (iii) Given that. New concentrations of A=2[A] New concentration of B=2[B] Plug the values we get.
Explanation:
The rate using the rate constant and the given concentrations [tex]\( \text{rate} = 2.1897 \text{ mol/L.s} \)[/tex].
The rate law for the reaction is given as: [tex]\rm \[ \text{rate} = k \times [a]^2 \times [b] \][/tex]
where:
[tex]\[ [a] = 4.11 \text{ mol/L} \]\\\ [b] = 3.71 \text{ mol/L} \][/tex]
[tex]\rm \[ k \][/tex] is the rate constant (to be determined)
To find the rate, we need to calculate the rate constant [tex](\( k \))[/tex] and then substitute the given concentrations of [tex]\( [a] \)[/tex] and [tex]\( [b] \)[/tex] into the rate law.
Step 1: Calculate the rate constant [tex](\( k \))[/tex] using the provided rate value and concentrations.
[tex]\[ \text{rate} = 2.1897 \text{ mol/L.s} \]\\\[k = \frac{\text{rate}}{[a]^2 \times [b]} \]\[k = \frac{2.1897 \text{ mol/L.s}}{(4.11 \text{ mol/L})^2 \times 3.71 \text{ mol/L}} \][/tex]
Step 2: Calculate the rate using the rate constant and the given concentrations.
[tex]\[ \text{rate} = k \times [a]^2 \times [b] \]\[ \text{rate} = \left(\frac{2.1897 \text{ mol/L.s}}{(4.11 \text{ mol/L})^2 \times 3.71 \text{ mol/L}}\right) \times (4.11 \text{ mol/L})^2 \times 3.71 \text{ mol/L} \]\[ \text{rate} = 2.1897 \text{ mol/L.s} \][/tex]
The correct result is [tex]\( \text{rate} = 2.1897 \text{ mol/L.s} \)[/tex].

Starting from rest and moving in a straight line, a runner achieves a velocity of 14 m/s in 10 seconds. what is the average acceleration of the runner?
The average acceleration of the runner will be 1.4 m/[tex]s^{2}[/tex]
An object is said to be accelerated if there is a change in its velocity. The change in the velocity of an object could be an increase or decrease in speed or a change in the direction of motion.
Acceleration is a vector quantity as it has both magnitude and direction. It is also the second derivative of position with respect to time or it is the first derivative of velocity with respect to time.
Average acceleration refers to the rate at which the velocity changes. We divide the change in velocity by an elapsed time to find out the average acceleration of anything.
given
final speed = 14 m/s
initial speed = 0
time taken = 10 seconds
Average acceleration = change in speed / change in time
= final - initial / time
= 14 - 0 / 10 = 1.4 m/[tex]s^{2}[/tex]
The average acceleration of the runner will be 1.4 m/[tex]s^{2}[/tex]
