A 0.5kg baseball experiences a 10n force for a duration of 0.1s. what is the change in?

The angular wave number and (b) the speed of the wave is 522.66 m/s.

Precise wavenumber is an amount in hypothetical material science that is characterized as the quantity of radians per unit distance. Precise recurrence is the rakish dislodging of any component of the wave per unit time. Likewise, in wave wording for a sinusoidal wave, the rakish recurrence alludes to the precise dislodging of any component of the wave per unit time. It is addressed by A recurrence is a rate, thus, the elements of this amount are radians per unit time. Precise hubs are level planes (or cones) where the likelihood of finding an electron is zero. This implies we can't at any point track down an electron in a rakish (or some other) hub. While outspread hubs are situated at fixed radii, precise hubs are situated at fixed points.

The time interval in fall motion is 1.86 seconds.

We need to know about fall motion to solve this problem. Gravity has a big role in fall motion. It can be described as

vt = vo + g . t

vt² = vo² + 2 . g . h

h = vo . t + 1/2 . g . t²

where vo is initial speed, vt is final speed, g is the gravitational acceleration (9.8 m/s²), h is height and t is time.

From the question above, we know that:

h = 30.8

vo = 7.4 m/s

Find the final velocity

vt² = vo² + 2 . g . h

vt² = 7.4² + 2 . 9.8 . 30.8

vt² = 54.76 + 603.68

vt² = 658.44

vt = 25.66 m/s

Find the time interval

vt = vo + g . t

25.66 = 7.4 + 9.8t

9.8t = 18.26

t = 1.86 seconds

Vector v is [tex]0,27\sqrt{2},27\sqrt{2}[/tex] for the given magnitude and the same direction as u, magnitude direction v = 93 u = 0, 4, 4.

Vector, in physics, a quantity that has both the magnitude and direction. It is typically represented by an arrow whose direction is same as that of the quantity and whose length is proportional to the quantity’s magnitude. Although vector has magnitude and direction, it does not have position. That is, as long as its length is not changed, vector is not altered if it is displaced parallel to itself.

In contrast to vectors, the ordinary quantities that have a magnitude but not a direction are called scalars. For example, displacement, velocity, and acceleration are vector quantities, while speed (magnitude of velocity), time, and mass are scalars.

To qualify as a vector, a quantity having the magnitude and direction must also obey certain rules of combination. One of these is the vector addition, written symbolically as A + B = C (vectors are conventionally written as boldface letters). Geometrically, vector sum can be visualized by placing the tail of vector B at the head of vector A and drawing vector C—starting from tail of A and ending at the head of B—so that it completes triangle. If A, B, and C are the vectors, it must be possible to perform the same operation and achieve the same result (C) in reverse order, B + A = C. Quantities such as the displacement and velocity have this property (commutative law), but there are quantities (e.g., finite rotations in the space) that do not and therefore are not vectors.

Given that,

|v|= 27 and u= 0,4,4

Now unit vector

u= [tex]\frac{u}{|v|}[/tex]=[tex]\frac{0,4,4}{|0,4,4|}[/tex]

  =0,4,4/[tex]\sqrt{0^{2}+4^{2}+4^{2} }[/tex] = 0,4,4/ [tex]\sqrt{32}[/tex]

   =0/[tex]4\sqrt{2}[/tex],4/[tex]4\sqrt{2}[/tex],4/[tex]4\sqrt{2}[/tex]

   =1/[tex]\sqrt{2}[/tex],1/[tex]\sqrt{2}[/tex]

now the vector v in same direction as u means,

v= |v|.u= 27*([tex]0,1/\sqrt{2}, 1/\sqrt{2}[/tex])

Thus,

v= [tex](0,27/\sqrt{2},27/\sqrt{2})[/tex]

The acceleration of the biker is 0.6 m s⁻².

Acceleration is the price of change in the velocity of an object with respect to time. Accelerations are vector quantities. The orientation of an object's acceleration is given through the orientation of the internet force performing on that item.

Acceleration is the name we deliver to any process where the speed changes. for the reason, that speed is a speed and a course, there are best methods so one can accelerate. Acceleration and Deceleration are one of the most essential subjects in the subject of science. Acceleration is the price of the converting of speed in any item, and deceleration refers to the price of acceleration,

forward force = 35 N

backward force = 20 N

Net force = 35 - 20

According to the given statement the speed of sirius is =2.3275862×10¹²km/s.

A waveform signal's wavelength, which is the distance between two identical locations (adjacent crests) in the succeeding cycles, determines whether it is sent through space or via a wire. Typically, in wireless systems, this length is specified in meters (m), centimeters (cm), or millimetres (mm).

Hydrogen has a spectral line at = 116nm=116×10⁻⁹m

Line is observed at = 107 nm=107×10⁻⁹m

Now, from the Hubble's law

V=[tex](\Delta \lambda / \lambda)[/tex]×C

Where,

v is the velocity

Δλ = Change in wavelength = 116 - 107= 9nm=9×10⁻⁹m

λ = Actual wavelength=116nm=116×10⁻⁹m

C is the speed of the light=3×10⁸m/s

on substituting the respective values, we get

Before calculating the length of the resonance tube, we have to first know the wavelength produced by the wave.

Using the expression

v = Foλ

V is the velocity of wave

Fo is the resonance frequency

λ is the wavelength
