Answer:
Option B. 1,100 Earth diameters
Solution:
Angular position of steroid,
(given)
To calculate the distance of asteroid, we use parallax method given as:
(1)
where,
From the relation:
l = ![\theta \times R](https://tex.z-dn.net/?f=%5Ctheta%20%5Ctimes%20R)
we get:
distance(d) or R = ![\frac{Earth diameter}{\theta}](https://tex.z-dn.net/?f=%5Cfrac%7BEarth%20diameter%7D%7B%5Ctheta%7D)
distance(d) or R = ![\frac{2\times radius of earth}{\theta}](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Ctimes%20radius%20of%20earth%7D%7B%5Ctheta%7D)
d = ![\frac{2\times 6350000}{8.726\times 10^{-4}}](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Ctimes%206350000%7D%7B8.726%5Ctimes%2010%5E%7B-4%7D%7D)
distance, d = ![1.455\times 10^{10} m](https://tex.z-dn.net/?f=1.455%5Ctimes%2010%5E%7B10%7D%20m)
Comparing it with Earth's diameter:
d = ![\frac{1.455\times 10^{10}}{2\times 6350000} = 1,146](https://tex.z-dn.net/?f=%5Cfrac%7B1.455%5Ctimes%2010%5E%7B10%7D%7D%7B2%5Ctimes%206350000%7D%20%3D%201%2C146)
Since, the value is close to 1,100 Earth diameters, therefore, option B is the right answer.
Answer:
No car will slide
Explanation:
Neither car will slide because proper bank does not required frictional forces. To prevent the car from traction through curve, a component of normal forces provides necessary centripetal forces. which prevent them to slide.
No car will slide since both car are going with the proper speed for given banking angle
An object like glass that allows light to pass through is said to refract light.
<h2>
PROPERTIES OF WAVES</h2>
Four general properties of waves are;
An object that allows light to pass through is said to refract light because of the followings
- If it absorbs, it will not transmit the light.
- If it reflect, some portion of the light will not be transmitted.
- Light refract when moving from one medium to another.
Therefore, An object like glass that allows light to pass through is said to refract light.

Answer:
Not Equal.
Explanation:
As the direction from New York to Miami (due South) is different from the direction from New York to Chicago (due West), the 2 velocities are not equal despite having the same magnitude. If both cars are to travel to the same destination at same speed, their velocities would be equal.
here force between two particles is given by Coulomb's law where two particles will either repel or attract each other
this force of attraction or repulsion is given by the equation
![F = \frac{kq_1 q_2}{r^2}](https://tex.z-dn.net/?f=F%20%3D%20%5Cfrac%7Bkq_1%20q_2%7D%7Br%5E2%7D)
here we know that
= two point charges
r = distance between two charges
so now we will substitute all values in it
![F = \frac{kq_0q_1}{d_1^2}](https://tex.z-dn.net/?f=F%20%3D%20%5Cfrac%7Bkq_0q_1%7D%7Bd_1%5E2%7D)
so above is the force between two point charges
