What is the approximate tangential speed of an object orbiting earth with a radius of 1. 8 × 108 m and a period of 2. 2 × 104 s? 7. 7 × 10–4 m/s 5. 1 × 104 m/s 7. 7 × 104 m/s 5. 1 × 105 m/s.
Answer: the period is 2.2 x 104 s, then the rotational speed is:
1 / 2.2x104 = 4.55x10-5 rad/s
We can solve for the tangential speed using the formula:
v = ωr
where ω is the rotational speed
v is the linear or tangential speed
r is the radius
So,
v = 4.55x10-5(1.8x108)
v = 5.1 x 104 m/s
Explanation:
The approximate tangential speed of an object orbiting earth with a radius of 1. 8 × 108 m is 5.1 x 104 m/s.
What is tangential speed?Any item moving along a circular path has a linear component to its speed called tangential velocity.
An object's velocity is always pointed tangentially when it travels in a circle at a distance r from the center. Tangential velocity is the name given to this.
The period is 2.2 x 104 s, then the rotational speed is:
1 / 2.2 x 104 = 4.55 x 10⁻⁵ rad/s
We can solve for the tangential speed using the formula:
v = ωr
where ω is the rotational speed
v is the linear or tangential speed
r is the radius
So,
v = 4.55 x 10⁻⁵ (1.8 x 108)
v = 5.1 x 104 m/s
Therefore, the tangential velocity is 5.1 x 104 m/s.

The fifth term of a geometric sequence is 781. 25. Each term of the sequence is of the value of the following term. Which recursive formula represents the situation?.
Answer: an = 5an-1
Explanation: Given fifth term of a geometric sequence is 781.25.
a5 = 781
Also, each previous term is 1/5 of the value of the current term.
Therefore, common ratio would be 5.
But we just need to find the recursive formula .
Recursive formula of a geometric sequence is given by
Plugging value of r in above formula, we get
Therefore, recursive formula would be represents the situation.
The recursive formula that represents the situation is: [tex]t_n = a^{(3/4)} * 781.25^{(1/4)} * n^{(1/4)}[/tex].
What is recursive formula?A recursive formula is one that defines any term in a sequence in terms of the term(s) before it.
Let the first term of the geometric sequence be 'a' and the common ratio be 'r'.
We are given that the fifth term is 781.25, so we can write:
a * [tex]r^4[/tex] = 781.25
We also know that each term is the value of the following term, so we can write the recursive formula:
t_n = r * t_(n-1)
Where t_n is the nth term of the sequence and t_(n-1) is the previous term.
To express the recursive formula in terms of 'a' and 'r', we can use the formula for the nth term of a geometric sequence:
[tex]t_n = a * r^{(n-1)[/tex]
Substituting the recursive formula, we get:
[tex]r * t_{(n-1)} = a * r^{(n-1)[/tex]
Dividing both sides by r^(n-1), we get:
[tex]t_{(n-1)} = a * r^{(n-2)[/tex]
So the recursive formula in terms of 'a' and 'r' is:
t_n = r * t_(n-1)
[tex]= r * (a * r^{(n-2)})\\\\= a * r^{(n-1)[/tex]
Now we can substitute the value of the fifth term (781.25) to solve for 'a' and 'r':
a * [tex]r^4[/tex] = 781.25
Dividing both sides by a, we get:
[tex]r^4[/tex]= 781.25/a
Taking the fourth root of both sides, we get:
r = [tex](781.25/a)^{(1/4)[/tex]
Substituting this value of 'r' into the recursive formula, we get:
[tex]t_n = a * ((781.25/a)^{(1/4)}){^(n-1)}\\\\= a^{(3/4)} * 781.25^{(1/4)} * n^{(1/4)}[/tex]
Therefore, the recursive formula that represents the situation is:
t_n = a^(3/4) * 781.25^(1/4) * n^(1/4)

Define the following
• Self-evaluation
• Personal skills
• Personal qualities
Answer: Let me help you with this one.
Explanation:
Self evaluation is a personal inspection, in which you check your physical mental and spiritual states, to make sure you are doing fine.
Personal skills are attributes you have in particular that can show specific prowess or an aid to eachother.
Personal qualities are traits that are used for how you qualify yourself on a level of it.
F(x, y) = e−x + y2, e−y + x2 , c consists of the arc of the curve y = cos(x) from − ???? 2 , 0 to ???? 2 , 0 and the line segment from ???? 2 , 0 to − ???? 2 , 0.
Given that y = cos(x) makes up part of the boundary of C, I suspect you mean the given points to be (-π/2, 0) and (π/2, 0).
I also assume the given vector field is
[tex]\vec F(x,y) = \left\langle e^{-x} + y^2, e^{-y} + x^2 \right\rangle[/tex]
Since [tex]\vec F[/tex] has no singularities on C or in its interior, Green's theorem applies:
[tex]\displaystyle \int_C \vec F(x,y) \cdot d\vec r = \iiint_D \frac{\partial(e^{-y}+x^2)}{\partial x} - \frac{\partial(e^{-x}+y^2)}{\partial y} \, dA = 2 \iiint_D (x + y) \, dA[/tex]
where D is the interior of C, the region
[tex]D = \left\{ (x, y) : -\dfrac\pi2 \le x \le \dfrac\pi2 \text{ and } 0 \le y \le \cos(x) \right\}[/tex]
The integral then reduces to
[tex]\displaystyle 2 \iint_D (x + y) \, dA = 2 \int_{-\frac\pi2}^{\frac\pi2} \int_0^{\cos(x)} (x + y) \, dy \, dx[/tex]
[tex]\displaystyle 2 \iint_D (x + y) \, dA = 2 \int_{-\frac\pi2}^{\frac\pi2} \left( x\cos(x) + \frac12 \cos^2(x) \right) \, dx[/tex]
[tex]\displaystyle 2 \iint_D (x + y) \, dA = 2 \int_{-\frac\pi2}^{\frac\pi2} \left( x\cos(x) + \frac{1 + \cos(2x)}4 \right) \, dx[/tex]
[tex]\displaystyle 2 \iint_D (x + y) \, dA = \frac12 \int_{-\frac\pi2}^{\frac\pi2} \left( 4x\cos(x) + 1 + \cos(2x) \right) \, dx[/tex]
Since 4x cos(x) is an odd function over the symmetric interval [-π/2, π/2], its contribution to the integral is 0, and the remaining integral is trivial.
[tex]\displaystyle 2 \iint_D (x + y) \, dA = \frac12 \int_{-\frac\pi2}^{\frac\pi2} \left( 1 + \cos(2x) \right) \, dx = \boxed{\frac\pi2} [/tex]
