The symbol Si represent Silicon and the Symbol Ge represents Germanium.
A transistor is a semiconductor device which is used to switch or amplify electrical signals and power. To amplify electric current or to block its passage these transistors are used. Bipolar transistors, Field-effect transistors, and Insulated-gate bipolar transistors are the three types of transistors. The first transistor is the point-contact transistor which is invented in 1947.
Transistors are formed by connecting two diodes back to back. It has got two PN junctions. In the past transistors were made from Germanium and nowadays they are made from very pure Silicon. The symbol Si represent Silicon and the Symbol Ge represents Germanium.

a baseball player is dashing toward home plate with a speed of 4.7 m/s when she decides to hit the dirt. she slides for 1.5 s , just reaching the plate as she stops (safe, of course).
She decides to hit the dirt in -2.64 m/s in First equation and 2.59m in second equation.
Using 1st equation of motion,

How is speed measured in baseball?Sprint Speed, a Stat cast metric that was first used in the 2017 season, counts the number of feet per second a player covers in his quickest one-second span.
Currently, "qualifying runs" from these two groups are included in the metric:
• Runs from second base following an extra-base hit but eliminating runs of two bases or more on non-homers.
• Runs scored from first base to home on "tipped" or "weakly hit" balls.
A player's seasonal average is calculated using the best third of these runs on average.

what is the geometric relationship between the force f and the cross-section area a under consideration?
The cross-sectional area A under consideration is parallel to the force F.
What do you mean by force?An influence that can alter an object's motion is referred to as a force in physics. An object with mass can change its velocity, or accelerate, in response to a force by moving away from rest, for example. Intuitively, pushing or pulling can be used to describe forces. As a vector quantity, a force is one that has both magnitude and direction. It is expressed as a newton in the SI system (N). F is a symbol that stands for force (formerly P). The net force exerted on an object is equal to the rate at which its momentum varies over time, according to Newton's second law in its original version.

a) find the velocity, in feet per second, at time : (b) find the velocity (in ft/sec) of the particle at time . (c) find all values of for which the particle is at rest. (if there are no such values, enter none . if there are more than one value, list them separated by commas.)
The velocity of a particle at time t is 4t³- 7, at time t = 3 is 101 ft/sec, and at rest is ∛7/4 sec.
The position of a particle at time t is
s(t) = t⁴ - 7t + 22, where t > 0
(A) Velocity at time t is
V(t) = s'(t)
Or, V(t) = 4t³ - 7 × 1 + 0
Or, V(t) = 4t³- 7
Hence, the velocity at time t is 4t³- 7.
B) Velocity ar time t = 3 is
V(3) = 4(3)³- 7
Or, V(3) = 101 ft/sec
Hence, the velocity at time t = 3 is 101 ft/sec.
(C) When particle is at rest, V(t) = 0
Then, 4t³ - 7 = 0
Or, t³ = 7/4

I already checked the answer in the answer book it's velocity= 320 m/s but I don't understand how
If anyone can help me please do
If a boy heard the thunder 18.74998 seconds after the lightening of a storm which is at a distance 6km , so the speed of sound in air is 320m/s.
As we know that,
Speed = Distance / Time
Firstly we calculate the time taken by light to travel distance 6 Km.
Given,
Distance = 6Km
Speed = 3000000m/s
Time = D/ S
= 6000/ 3000000
= 0.002s
So, the time taken by light to reach the ground is 0.002s.
Now,
Time taken by sound to reach the ground = time taken by light + 18.749.
0.002 + 18.749
= 18.75
Now, t = 18.75
d = 6km
Speed = 6000/18.75
= 320m/s
Thus, we concluded that if boy heard the thunder 18.74998 seconds after the lightening of a storm which is at a distance 6km , so the speed of sound in air is 320m/s.

Answer:
The magnitude of the resultant vector, two vectors of the same magnitude are added; one pointing east, one west is Zero.
Explanation:
Vector resolution is the process of identifying the magnitude and direction of a vector's components visually or trigonometrically. The magnitudes of the aforementioned vector are due to the fact that the vector sum of all forces must still be zero.
A resultant force can be found by adding two forces together. A single force can be resolved (divided) into two component forces that are at right angles to one another.
A vector quantity with magnitude and direction can be used to represent a force. The pulling force may be resolved using vector diagrams into a horizontal component acting to the right and a vertical component acting upwards (or forces acting in opposite directions).

A substance's density is defined as its mass per unit of volume. Density is most frequently represented by the symbol, however Latin letter D may also be used. The formula for density is mass divided by volume:
ρ = m / v
The error's absolute value is multiplied by 100%, divided by the accepted value, and then converted to a percent.

acceleration of object A.
The acceleration is maximum when the displacement of the object is maximum.
We understand that speed is most when y=zero, displacement is zero, and acceleration is zero, this means that the machine is in equilibrium. therefore, at a factor in simple harmonic motion, the maximum pace can be calculated by the usage of the formulation v=Aω. the rate may be most in easy harmonic movement, while the acceleration is zero.
The pendulum oscillating backward and forward from the suggested role is an example of easy harmonic movement. Bungee leaping is an example of simple harmonic motion. The jumper oscillates up and down in the present process SHM because of the pliancy of the bungee wire.
The maximum displacement of the bob from its implied role. OA or OB is called its amplitude. because the bob is at its lowest position on point O. Its potential power is minimal whilst its kinetic power is maximum.

what is the index of refraction of a substance that has a critical angle of 68.4º when submerged in water (n
The refractive index of the substance for the critical angle 68.4° is found as 1.43400055
To find the index of refraction, the given values are:
Critical angle is 68.4°.
What is the refractive index?The refractive index can be defined as the ratio of the speed of light in the medium to the speed in the vacuum.
The formula of the refractive index is as follows:
Where,
n is the refractive index
c is the velocity of light in a vacuum ( 3 × 108 m/s)
v is the velocity of light in a substance
The vacuum has a refractive index of 1. The refractive index of other materials can be calculated from the formula mentioned. Higher the refractive index, the higher the optical density and slower is the speed of light.The refractive index of different media can be listed in the table below:
Material Refractive Index
Air 1.0003
Water 1.333
Diamond 2.417
Ice 1.31
Ethyl Alcohol 1.36
Now, finding the value of refractive index,
As the value of critical angle is given, θ = 68.4°,
θc = Sin ⁻¹ ([tex]\frac{n2}{n1}[/tex])
Considering the given values, n2 = 1.3333
θc = θ = 68.4°
So, n1 = ( n Water) / ( sin θc)
= 1.33333 / sin 68.4°
= 1.43400055
Thus, n1 ca be found as,1.43400055
The refractive index of the substance for the critical angle 68.4° is found as 1.43400055
