Answer:

When kelvin pulls cotton shirt off his body, the electrons get transferred from the shirt in the form of static charges that means electrons to the body. So, the shirt becomes positively charged and his body becomes negatively charged.  

So, the transfer of charge from shirt to the body will takes place. And also we can hear a crackling sound. We can hear it and observe it as a sparkle.

Therefore the cotton has higher tendency to attract the electrons than human skin.

Answer:

Shirt becomes negatively charged and Kelvin's body becomes positively charged.

Explanation:

An electron is the elementary particle of atom. It has a negative charge of - 1.6 x 10^-19 C.

If a body loses some electrons, it becomes positively charged and if the body gains some electrons then it becomes negatively charged.

According to the question, cotton has higher tendency to attract the electrons, it means it has a tendency to acquire negative charge.

If Kelvin pulls his cotton shirt the electrons get transfer from his body to cotton shirt. It means the cotton shirt acquire a negative charge and the human body acquires a positive charge as it loses electrons.

So, shirt becomes negatively charged and Kelvin's body becomes positively charged.

It makes the data thet they collect more reliable so if they need the data again, they have already tested it a few times so therefor they know that it is right.

The 10-lb block has a speed of 4 ft/s when the force of f=(8t2)f=(8t2) lb is applied. determine the velocity of the block when t
KatRina [158]

The velocity of the block when t == 2 s is 60.7 ft./sec.

Equations of Motion.

Here the friction is F_f = \mu_k N = 0.2 N

+ \uparrow \sum F_y = ma_y; \quad N – 10 = \frac { 10 } { 32.2 }(0) \quad N = 10 lb \\ \begin{aligned} \underrightarrow{ + } \sum F_x = ma_x; \quad 8t^2 – 0.2(10 &) = \frac { 10 } { 32.2 }a \\ & a = 3.22(8t^2 – 2) ft/s^2 \end{aligned}

Kinematics.

The velocity of the block as a function of t can be determined by

integrating dv = adt using the initial condition v = 4 ft./s at t = 0.

\int_{ 4 ft/s }^{ v } dv = \int_0^t 3.22(8t^2 – 2)dt \\ \begin{aligned} v – &4 = 3.22 (\frac 8 3 t^3 – 2t) \\ & v = \{8.5867t^3 – 6.44t + 4 \} ft/s \end{aligned}

The displacement as a function of t can be determined by integrating

ds = vdt using

the initial condition s = 0 at t = 0

\int_0^s ds = \int_0^t (8.5867t^3 – 6.44t + 4)dt \\ s = \{2.1467t^4 – 3.22t^2 + 4t \} ft

at t = 2 sec

s = 30 ft.

Thus, at s = 30 ft.,

\begin{aligned} v &= 8.5867(2.0089^3) – 6.44(2.0089) + 4 \\ &= 60.67 ft/s \\ &= 60.7 ft/s \end{aligned}

Kinematics is a subfield of physics, developed in classical mechanics, that describes the motion of points, bodies (objects), and systems of bodies (groups of objects) without considering the forces that cause them to move.

Kinematics, as a field of study, is often referred to as the "geometry of motion" and is occasionally seen as a branch of mathematics. A kinematics problem begins by describing the geometry of the system and declaring the initial conditions of any known values of position, velocity and/or acceleration of points within the system.

Then, using arguments from geometry, the position, velocity and acceleration of any unknown parts of the system can be determined. The study of how forces act on bodies falls within kinetics, not kinematics. For further details, see analytical dynamics.

Describe the interactions with the Sun, Earth and Moon system that result in Tides.
bazaltina [42]

Answer:The sun, earth, and moon are held together by gravity, and they interact in lots of ways.

  • The tides are another interaction in the sun-earth-moon system. The tides happen because the moon and sun pull on the oceans, causing them to rise and fall each day. The moon has a bigger effect than the sun because it is closer.
