Explanation:
Initial speed of the planet, u = 18.2 km/s = 18200 m/s
Final speed of the planet, v = -22.9 km/s = -22900 m/s
Time interval, t = 2.04 years
Since, 
Time interval, 
(a) The total change in the planet's velocity is calculated as :
(b) Let a is the average acceleration of the planet. It can be calculated as :
Hence, this is the required solution.
C
As there have current goes through the circuit and current will induce magnetic field
Answer:
Explanation:
Zeeman Effect -
In the presence of static magnetic field , the process of splitting of the spectral line into several components , is called Zeeman effect .
On the sun , there is a strong magnetic field , and hence , can show Zeeman effect .
And due to this ,
The sunspots can be studied by using this effect .
Sunspots are the darker region on the surface of Sun .
The beam is refracted at 53.17-degree angle (asin 0.800414 = 53.17-degree). This problem can be solved by using the Snell's Law which described the refracted beam angle which traveled through a different media, in this case, through water and air. The formula of Snell's Law is stated as n1 sin θ1= n2 sin θ2. In this formula n1 is the refraction index of medium 1, θ1 is the normal light angle in the medium 1, n2 is the refraction index of medium 2, and θ2 is the normal light angle in the medium 2<span>. </span>
In a free body diagram for an object projected upwards;
- the acceleration due to gravity on the object is always directed downwards.
- the velocity of the object is always in the direction of the object's motion.
An object projected upwards is subjected to influence of acceleration due to gravity.
As the object accelerates upwards, its velocity decreases until the object reaches maximum height where its velocity becomes zero and as the object descends its velocity increases, which eventually becomes maximum before the object hits the ground.
To construct a free body diagram for this motion, we consider the following;
- the acceleration due to gravity on the object is always directed downwards
- the velocity of the object is always in the direction of the object's motion.
<u>For instance:</u>
upward motion for velocity ↑ downward motion for velocity ↓
↑ ↓
↑ ↓
acceleration due to gravity ↓
