A comet is in an elliptical orbit around the Sun. Its closest approach to the Sun is a distance of 4.7 1010 m (inside the orbit

Lubov Fominskaja [6]

Answer:

58515.9 m/s

Explanation:

We are given that

$d_1=4.7\times 10^{10} m$

$v_i=9.5\times 10^4 m/s$

$d_2=6\times 10^{12} m$

We have to find the speed (vf).

Work done by surrounding particles=W=0 Therefore, initial energy is equal to final energy.

$K_i+U_i=K_f+U_f$

$\frac{1}{2}mv^2_i-\frac{GmM}{d_1}=\frac{1}{2}mv^2_f-\frac{GmM}{d_2}$

$\frac{1}{2}v^2_i-\frac{GM}{d_1}+\frac{GM}{d_2}=\frac{1}{2}v^2_f$

$v^2_f=2(\frac{1}{2}v^2_i-\frac{GM}{d_1}+\frac{GM}{d_2})$

$v_f=\sqrt{2(\frac{1}{2}v^2_i-\frac{GM}{d_1}+\frac{GM}{d_2})}$

Using the formula

$v_f=\sqrt{v^2_i+2GM(\frac{1}{d_2}-\frac{1}{d_1})}$

$v_f=\sqrt{(9.5\times 10^4)^2+2\times 6.7\times 10^{-11}\times 1.98\times 10^{30}(\frac{1}{6\times 10^{12}}-\frac{1}{4.7\times 10^{10})}$

Where mass of sun= $M=1.98\times 10^{30} kg$

$G=6.7\times 10^{-11}$

$v_f=58515.9 m/s$

A wheel is rotating at a rate of 2.0 rev every 3.0s. through what angle, in radian , does the wheel rotate in 1.0s?

igomit [66]

Answer:

$4 \pi$

Explanation:

First of all, let's convert 2.0 rev into radians:

$1.0 rev = 2\pi rad\\2.0 rev = 4 \pi rad$

This means that the angular speed of the wheel is

$\omega = 2.0 rev/s = 4 \pi rad/s$

The angle through which the wheel rotates in a time t is given by

$\theta=\omega t$

And substituting t=1.0 s, we find

$\theta=(4\pi rad/s)(1.0 s)=4 \pi rad$

What would be the best example of a fine motor skill? a. Climbing to the top of a large hill b. Feeding yourself with a spoon c.

Elden [556K]

Answer:

The correct answer is

b. Feeding yourself with a spoon

Explanation:

There are two categories of motor skills, fine motor skills and gross motor skills

Fine motorskills also known as dexterity is the synchronized use of small muscles like muscles in the wrists, hands and fingers along with the eyes. Fine motor skills are used for tasks like turning pages or using the computer key board that requires coordinated and precise movements. Human dexterity is reflected in the level of complexity of functions controlled by the nervous system.

Example of fine motor skill is Feeding yourself with a spoon while gross motor skill includes climbing to the top of a large hill spoon, running in a race and crawling
