find an expression for the electric field as a function of position r from the center of sphere inside the shell. use a minus sign if the field points inward.
The electric field E inside a spherical shell of charge Q and radius R is given by:
E(r) = (3Q/(4πε0)) * (r / (R^3)) for 0 < r < R
E(r) = 0 for r >= R
where ε0 is the vacuum permittivity, r is the radial distance from the center of the sphere, and R is the radius of the spherical shell. The electric field points inward for 0 < r < R, so a minus sign should be used in the expression.
The electric field is defined as the force F acting on the point's unit positive electric charge, q. E = F/q is the equation to calculate the electric field. A negative charge experiences force in the opposite direction from a positive charge. A vector quantity with both direction and magnitude is the electric field. Field lines or lines of force are used to represent the electric field.
There are three cases in this derivation.

i use a 2 kg hammer to hit a 0.5 kg ball. if the ball accelerates at 12 m/s2 what is the acceleration of the hammer?
So the acceleration of the hammer is 3 m/s^2.
Newton's Third Law of Motion, which stipulates that there is an equal and opposite response to every action, may be used to calculate the hammer's acceleration.
In this instance, the hammer's force on the ball is the action, and the ball's force on the hammer is the response.
Since force is equal to mass times acceleration (F = ma),
The acceleration of the hammer can be calculated as follows:
a_hammer = F_ball / m_hammer
a_hammer = (m_ball * a_ball) / m_hammer
a_hammer = (0.5 kg * 12 m/s^2) / 2 kg

A plastic ball of mass 400 kg moves with a velocity of 30 m/s. It collides with a second plastic ball of mass 200 kg moving in the same direction at 10 m/s. After the collision, the 200 kg ball has a velocity of 26 m/s, in the same direction. What is the new velocity of the 400 kg ball? Show your equation and work.
The total momentum during the collison is conserved. Using this concept, the final velocity of the 400 kg ball is 22m/s.
What is momentum ?Momentum of an object is the product of its mass and velocity. During collision between two bodies the total initial momentum is equal to the total final momentum.
Momentum of ball of 400 kg with 30 m/s = 400 × 30 = 12000 kg m/s.
momentum of ball of 200 kg with 10 m/s velocity = 200 × 10 = 2000 kg m/s.
total initial momentum = 2000 + 12000 kg m/s = 14000 kg m/s.
Now, final momentum of 200 kg ball with 26 m/s = 200 × 26 = 5200 kg m/s.
total final momentum = total initial momentum = 14000 kg m/s.
thus 5200 kg m/s + (400 kg × v m/s) = 14000 kg m/s
v = (14000 - 5200 kg m/s )/400 kg = 22 m/s.
Therefore, the final velocity of 400 kg ball is 22 m/s.

how long does it take a motor with an output of 8.0 w to lift a 2.0 kg object 88 cm?
The takes a motor with an output of 8.0 W approximately 3.632 minutes to lift a 2.0 kg object 88 cm.
The time it takes a motor with an output of 8.0 W to lift a 2.0 kg object 88 cm can be calculated using the equation for work, which is given by:
W = F * d
where W is the work done, F is the force required to lift the object, and d is the distance the object is lifted. The force required to lift the object can be calculated using the equation for weight, which is given by:
F = m * g
where m is the mass of the object and g is the acceleration due to gravity (9.8 m/s^2).
Substituting the values for m and g into the equation for weight, we get:
F = 2.0 kg * 9.8 m/s^2 = 19.6 N
Now that we know the force required to lift the object, we can substitute this value into the equation for work to calculate the work done:
W = F * d = 19.6 N * 88 cm = 1717.28 J
Finally, we can use the equation for power, which is given by:
P = W / t
where P is the power of the motor and t is the time it takes to lift the object. We know the power of the motor (8.0 W) and the work done (1717.28 J), so we can calculate the time it takes to lift the object:
t = W / P = 1717.28 J / 8.0 W = 215.91 seconds = 3.632 minutes

Question 10.4 ptsLet u and v be vectors in R². Which of the following is/are true?(select all that apply)The magnitude of a vector cv is c times the magnitude of v. where c is any scalar.The operation of vector addition is not commutativeA column vector in R² is a 1 x 2 matrix.None of the choices is correct.The set of all vectors which are scalar multiple of a nonzero vector u is a line through u and 0.
In physics, vectors are used to represent physical quantities that have both magnitude and direction, such as velocity, force, and acceleration. The given statements are true.
(a) The magnitude of a vector cv is c times the magnitude of v, where c is any scalar. This means that if you multiply a vector by a scalar, the magnitude of the result is simply a scaling of the original magnitude. For example, if v represents a velocity, then 2v represents a velocity with twice the magnitude of v in the same direction.
(b) The operation of vector addition is not commutative, i.e., u + v ≠ v + u in general. This means that the order of addition matters for vectors. For example, if u and v represent forces acting on an object, then u + v represents the net force resulting from applying u first and then v, while v + u represents the net force resulting from applying v first and then u.
(c) A column vector in R² is a 1 x 2 matrix, which is a mathematical representation of a vector in two dimensions. In physics, column vectors are commonly used to represent positions and displacements in two-dimensional space.
(d) The set of all vectors which are scalar multiples of a nonzero vector u is a line through u and 0. This means that if u is a nonzero vector, then all vectors that can be obtained by multiplying u by scalars form a line that passes through u and the origin. This line represents all possible positions that can be reached by traveling along the direction of u and varying the magnitude.

a particle travels along a straight line with an acceleration of a=(10−0.2s) m/s2 , where s is measured in meters
The required velocity of a particle travelling in a straight line with the given acceleration function at s = 10 m is calculated to be 15.52 m/s.
At, s = 0, the velocity of the particle is v = 9 m/s.
Now, let us find the particle's velocity at s = 10 m,
Consider the acceleration function, a = (10 − 0.2 s)
Since, a = v dv/ds, so the above equation can be written as,
v dv/ds = (10 − 0.2 s)
Integrate the above function using the variable separable approach,
9 to v ∫ v dv = 0 to 10 ∫ (10 − 0.2 s) ds
9 to v (v²/2) = 0 to 10 (10 s - 0.2 s²)
v²/2 - 9²/2 = 10× 10 - (0.2 × 10²)
v = 15.52 m/s

it would decrease
it would stay the same
it would increase
If the acceleration during the time 0 < t < 1.5 is increased to +10 m/s^2, then the total displacement would be increased.
A change in acceleration affects displacement because acceleration is a measure of the rate of change of velocity. If acceleration increases, then the velocity will increase more quickly, resulting in a larger displacement in a given amount of time. Conversely, if acceleration decreases, then the velocity will decrease more quickly, resulting in a smaller displacement in a given amount of time. Time affects displacement because the longer a distance is traveled, the greater the displacement. The rate of change in displacement is determined by the speed of the object, so the longer the time, the greater the displacement.

using the field of view calculated in exercise 1 for the high power lens, what is the approximate diameter of each of the cells in the bacteria coccus form slide in photo 10? show your calculations.
The approximate diameter of each cell in the Bacteria Coccus Form slide in Photo 10 is 0.33 micrometers.
The formula to calculate the diameter of an object in the field of view is:
diameter = field of view (FOV) / magnification
First, we need to convert the FOV from millimeters to micrometers:
0.2mm = 200µm
Now, we can use the formula to calculate the diameter:
diameter = 200µm / 600 = 0.33µm
So, the approximate diameter of each cell in the Bacteria Coccus Form slide in Photo 10 is 0.33 micrometers.
Field of View (FOV) is the extent of the observable world that is seen at any given moment. It refers to the extent of the observable environment that is seen by an observer's eye or a camera lens. In the context of visual representation, FOV is often expressed as an angle, which defines the breadth of the visible area. A larger FOV allows more of the environment to be seen at once, while a smaller FOV provides a narrower, more focused view.

what will be value of mag field after capacitor fullly charged
The value of the magnetic field after a capacitor is fully charged will be zero. This is because once the capacitor is fully charged and the electric field is no longer changing, the magnetic field will disappear.
When a capacitor is fully charged, the value of the magnetic field will be zero. This is because the electric field stops changing once the capacitor is fully charged, which in turn means that the magnetic field associated with it will no longer exist.
This can be explained by the principle that magnetic fields are generated due to the changes in electric fields, which no longer exist in the case of a fully charged capacitor. Thus, it is important to note that the value of the magnetic field will be zero once the capacitor is fully charged.

Why is kinetic energy not conserved in inelastic collisions? What if, theoretically, there was an inelastic collision that did not generate any heat?
Kinetic energy is not conserved in inelastic collisions because part of the energy is converted into internal energy. If there was an inelastic collision that did not generate any heat, it would still result in a decrease in total kinetic energy, as the internal energy would remain constant.
In an inelastic collision, kinetic energy is not conserved due to the conversion of some of the energy into internal energy. This is the case even if the collision does not produce any heat.
The total kinetic energy still decreases, as the internal energy remains constant. Therefore, in an inelastic collision, part of the kinetic energy is transformed into internal energy, resulting in a decrease in the total kinetic energy of the system.

Engineering notation is the representation of expressing the numbers that are too big or too small and are represented in the decimal form times 10 raise to the power. It is similar to the scientific notation but in engineering notation, the powers of ten are always multiples of 3.
Using scientific notation, one can express extremely big or extremely small values. When a number between 1 and 100 is used, it is written in scientific notation.
