A physics student walks 100 meters in 80 seconds. The student stops for 30 seconds, and then walks 200 meters farther in 90 seconds. What is the average speed of the entire walk?.
Answers
The average speed of the student for his entire walk is equal to 1.5 m/s. Therefore, option (b) is correct.
What is the average speed?
The average speed of a body is calculated as the total distance traveled in a fixed interval of time. The average speed can be determined by dividing the total distance traveled by a body by the total time.
The average velocity is a single value if the object moves uniformly. Speed is a scalar quantity, it has no specified direction. The average speed has the S.I. unit the same as velocity i.e. m/s.
Given the distance covered by a student in first 80 sec = 100m
After stooping for 30sec again cover a distance of 200m in 90sec.
The total distance traveled by the student = 100 + 200 = 300m
The time taken by student to cover distance = 80 + 30 +90 = 200 sec
The average speed of the student = total distance/ total time taken
= 300/200 = 1.5 m/s
Therefore, the average speed of the student is equal to 1.5m/s.

Write an equation for the transformed logarithm shown below, that passes through (3,0) and (0,2) f(x)= Question Help: −b Video
Answers
The equation for the transformed logarithm that passes through the points (3,0) and (0,2) can be written as f(x) = -b * log(base a)(x - h) + k, where a, b, h, and k are constants to be determined.
To find the equation for the transformed logarithm, we need to use the given points (3,0) and (0,2) to determine the values of a, b, h, and k. Let's start with the point (3,0). Plugging the x-coordinate (3) into the equation, we have:
0 = -b * log(base a)(3 - h) + k
Next, we'll use the point (0,2) to obtain another equation. Plugging the x-coordinate (0) into the equation, we get:
2 = -b * log(base a)(0 - h) + k
Simplifying these equations, we have a system of equations to solve for a, b, h, and k. However, since the equation involves a logarithm, we need more information to determine the specific values of a, b, h, and k.The transformed logarithm function includes transformations such as vertical stretches/compressions (b), horizontal shifts (h), and vertical shifts (k). Without more specific information about these transformations or the base of the logarithm, it is not possible to determine the equation uniquely.
In general, the equation for a transformed logarithm can be written as f(x) = -b * log(base a)(x - h) + k, where a, b, h, and k are constants determined by the specific transformations applied to the logarithm function. It's important to have additional information or instructions to determine the values of a, b, h, and k and provide an equation that accurately represents the given transformed logarithm.

Answers
We know that:
- She has some of it complete, but the robot still needs 3 arms and 6 wheels.
- Patty has saved up $68, which is enough to buy the parts she needs.
- Arms costs $13 and wheels costs $4
We must find how much money is left after making the purchase.
To find it we must subtract the money spent on the purchase from the money saved.
- money spent:
Is the money spent when she buys the arms and the wheels
\(\text{ \$}13\cdot3+\text{ \$}4\cdot6=\text{ \$}63\)So, the money spent is equal to $63
- money saved
Is the money Patty has saved.

Answers
(a) For r < R, ϵ₀(∇⋅E) = 3ρ₀. For r ≥ R, ϵ₀(∇⋅E) = 0. (b) ρ(r) = ρ₀ for r < R and 0 for r ≥ R. Q = ρ₀V, where V is the volume of the sphere. (c) As R → 0 (fixed Q), ρ₀ becomes infinitely large, representing a point charge at the center, akin to the Dirac delta function δ³(r).
(a) To check the charge density ρ(r) using Gauss's Law, we need to compute ϵ₀(∇⋅E) everywhere, both for r < R and r ≥ R.
1. For r < R:
The electric field inside the sphere is given by E(r) = ρ₀ * r.
∇⋅E = (1/r²) ∂(r²E)/∂r = (1/r²) ∂(r² ρ₀ r)/∂r = (1/r²) ρ₀ ∂(r³)/∂r = (1/r²) 3ρ₀ r² = 3ρ₀.
Therefore, for r < R, (∇⋅E) = 3ρ₀.
2. For r ≥ R:
The electric field outside the sphere is given by E(r) = ρ₀ (R/r)³ r.
∇⋅E = (1/r²) ∂(r²E)/∂r = (1/r²) ∂(r²ρ₀ (R/r)³ r)/∂r
Now, let's compute the derivative:
∂(r² ρ₀ (R/r)³ r)/∂r = ∂(ρ₀ R³ r)/∂r = 0.
Since the electric field E is spherically symmetric outside the sphere, its divergence (∇⋅E) is zero.
Therefore, for r ≥ R, (∇⋅E) = 0.
(b) To express the charge density ρ(r) in terms of the total charge Q = ∫dτρ(r) on the sphere, we integrate the charge density over the volume of the sphere.
For r < R:
ρ(r) = ρ₀
For r ≥ R: ρ(r) = 0
Since the charge density is uniform inside the sphere and zero outside, the total charge Q can be calculated as:
Q = ∫dτρ(r) = ∫ρ₀ dτ = ρ₀ ∫dτ
The integral represents the volume of the sphere, so we have:
Q = ρ₀ * V
where V is the volume of the sphere.
(c) As R → 0 while holding Q fixed, the volume V of the sphere also approaches zero. Therefore, the charge density ρ₀ must increase proportionally to keep the total charge Q fixed.
This behavior is related to the concept of the Dirac delta function δ³(r), which represents an infinitely concentrated charge at a point. As the radius becomes infinitesimally small, the charge becomes infinitely concentrated at the center of the sphere, corresponding to the limit of the Dirac delta function.

a circle has a circumference of 16 feet. what is the radius of the circle, in feet? individual question 4 8 16 32
Answers
The correct answer is the radius of the circle is 2.54648 ft.
The circumference of a circle or ellipse in geometry is known as its perimeter. That is, if the circle was opened up and straightened out to a line segment, the circumference would be said the length of the arc.
The curve length around any closed figure is more commonly referred to as the perimeter.
We know that Circumference = \(2\pi r\) and \(\pi\) ≈ 3.14159,
Circumference = \(2\pi r\)
16 = \(2\pi r\) (after substituting)
16/2\(\pi\) = 2\(\pi\)r/2\(\pi\) (remove 2\(\pi\) by dividing both sides with the mentioned term)
r = 8/\(\pi\)
r = 8/\(\pi\) (ft.)
\(\pi\) ≈ 3.14159 (value of \(\pi\))
Hence, the radius of the circle when its circumference is 16 feet is r ≈ 2.54648 ft. which is the approximate value.
Checking our work:
Circumference = 2\(\pi r\)
Circumference = 2 (3.14159) (2.54648)
Circumference = 15.999
Circumference ≈ 16 ft.

Explain what the constant rate of change means in the context
Answers
In this expression, the Constant Rate of change will be $6.25
Given that Steven earns $31.25 for 5 hours and $50 for 8 hours. In this, we can say that there is a constant Rate of change which is charged for each hour Steven works.
Constant Rate of Change is when the Rate of an expression remains constant throughout system equations. In this case, we can find out the constant rate of change by:
Taking expression, Amount = C.R. * Hours, where C.R is Constant Rate 'x'
So, we get: Amount = x * Hours.
Comparing this expression to given conditions we get:
For Amount 31.25 and 5 Hours: 31.25 = 5x => x = 6.25
For Amount 50 and 8 Hours: 50 = 8x => x = 6.25
