Answer:
r = 0.63 AU
Explanation:
In this question, we are interested in calculating the distance from the sun that the satellite should orbit.
From the question;
given time period of satellite is T = 0.5 year
Mathematically;
T is directy proportional to r^3/2
Hence;
T = constant * r^3/2
0.5/1 = r^1.5 / 1^1.5
( 1 is the the distance of the earth’s orbit to the sun in AU)
r = 0.63 AU
Answer:
<h2>18.51 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula
m is the mass
v is the velocity
From the question we have
We have the final answer as
<h3>18.51 J</h3>
Hope this helps you
Conversion of mass from grams into kg :
Answer:
<em>A. 22 </em>
<em>B. NO</em>
Explanation:
<u>A.</u>
During a collision , <em>the net external force on the system is zero .</em>
hence , the total momentum of the system can be CONSERVED .
let the mass of frosty and snowflake be m ;
- initial velocity of frosty be = 25
- final velocity of frosty be = 13
- initial velocity of snowflake be = 10
- final velocity of snowflake be = x
therefore from principle of conservation of momentum ,
<em></em>
so ,
<u>answer for A. 22 </u>
<u>B</u>.
<em>The collision is NOT ELASTIC.</em>
this is because if it had been elastic , the coefficient of restitution should have been 1 but it isnot i.e
≠ 1
<em>thus it's an inelastic collision.</em>
