what is the strength of the electric field at the position indicated by the dot in (figure 1)? express your answer in newtons per coulomb.

Since all three objects a, b and c repel one another, they possess charges of the same sign.

Assuming all three objects are conductors, the electric charge, either positive or negative, will be evenly distributed throughout the object.

Opposite charges attract each other, while same charges repel. Object a and b repel when they are brought together, which means that both objects have the same charge. This is the same case with object b and c. This means that all three objects possess the same charge.

Mechanical advantage has no unit, Hence, the statement that Mechanical advantage is expressed in newtons squared is False.

A primary machine's mechanical advantage quantifies how much work goes into it and is used to manipulate the load. In other words, it is the ratio of a machine's input to output work. It has no units because it is the ratio of two identical quantities.

Mathematically, mechanical advantage = load/effort or work output/ work input

Stone speed is equal to three times stone speed if the stones are the same size. The stone will touch the earth in 10/3s, or 3.3 seconds because gravity will affect both stones equally during the fall.

Gravitational force acts downhill when a stone is propelled vertically, while muscular force or an applied force acts upward.

Gravity tries to pull the stone down when it is thrown vertically upward, slowing down its motion. After a period, the velocity falls to zero as a result of this persistent downward drag.

The ball strikes the ground after 2.46 seconds.

The time interval can be calculated using the following equation:

t = [tex]\frac{2h}{g}[/tex]

where h is the height from which the ball was thrown (29.9 m), g is the acceleration due to gravity (9.8 m/s), and t is the time interval.

Substituting the values, we get:

t = (2 x 29.9 / 9.8) = (59.8 / 9.8) = [tex]\sqrt{6.1}[/tex] = 2.46s

So, the ball strikes the ground after 2.46 seconds.

The acceleration is 7m/s².

For Part a, we can use the equation of motion for constant acceleration:

v f = v_0 + a x t

where v f is the final velocity, v_0 is the initial velocity, a is the acceleration, and t is the time. Since the final velocity is 0, we can write:

t =  -v 0 / a

Next, we can use the distance formula:

d = v_0 x t + 0.5 x a x t²

where d is the distance traveled. Plugging in the value of t from the previous equation, we get:

d = v_0 x (-v_0 / a) + 0.5 x a x (-v_0 / a)²

d = -v_0² / 2a

Now, we can solve for v_0 using the value of d:

v_0 = (2 x a x d) = (2 x 18 x 300)=  102.9 feet/s

For Part b, we can use the equation for t from Part a:

t = -v_0 / a = -102.9 / 18 = 5.71 s

Acceleration is the rate of change of velocity of an object over time. It is a vector quantity with units of meters per second squared (m/s²) in the SI system. Acceleration can be caused by various factors such as force, changes in velocity, and changes in direction. Positive acceleration indicates that the velocity of an object is increasing, while negative acceleration indicates that the velocity is decreasing. In a uniform acceleration, the velocity of an object changes by an equal amount over equal time intervals.

The general antiderivative of the rate of change function "the rate of change of DVD orders is given by s(m) = 600m + 5DVDs per month" is "DVD orders = 300m^2 + 5m + c", where c is the constant of integration.

The antiderivative of a function is the original function whose derivative is equal to the given rate of change function. To find the antiderivative of the rate of change function "the rate of change of DVD orders is given by s(m) = 600m + 5 DVDs per month", we need to integrate the function with respect to the independent variable m.

The antiderivative of the function s(m) = 600m is 300m^2 and the antiderivative of the constant 5 is 5m. Adding these two antiderivatives, we get the general antiderivative of the rate of change function:

DVD orders = 300m^2 + 5m + c

where c is the constant of integration and represents the arbitrary offset from the original function. To find the value of c, additional information or boundary conditions are required. This antiderivative represents the total number of DVD orders as a function of the number of months since the beginning of the year.

The minimum length of the bolt required is 2.665 inches, plus an additional length for the hex head.

The length of a hex head bolt for a specific application can be determined by adding up the thicknesses of the different components that make up the assembly. In this case, the components include the mounting hole, the mounting thickness including the foot, the plain washer, and the lock washer.

The mounting hole size is 0.875 inches, which is the distance between the surfaces being connected. The mounting thickness including the foot is 1.500 inches, which represents the thickness of the material to which the bolt will be attached.

The plain washer thickness is 0.102 inches, which is added to ensure even distribution of pressure on the mounting surface and to prevent damage to the surface during tightening. The lock washer thickness is 0.188 inches, which is added to prevent the bolt from loosening over time.

In total, the thicknesses of these components are 0.875 + 1.500 + 0.102 + 0.188 = 2.665 inches. Therefore, the minimum length of the hex head bolt required for this application is 2.665 inches.

X2 = [2, 4, 6, 8]

Two elements in R4 that belong to the span of these vectors are:

a1X1 + a2X2 = [a1 + 2a2, 2a1 + 4a2, 3a1 + 6a2, 4a1 + 8a2]

So for example, if we choose a1 = 1 and a2 = -1, we get:

a1X1 + a2X2 = [1 - 2(-1), 2(1) - 4(-1), 3(1) - 6(-1), 4(1) - 8(-1)] = [3, 0, 9, -3]

To find an element of R4 that does not belong to the span of these vectors, we need to find a vector in R4 that cannot be expressed as a linear combination of X1 and X2.
