Answer:
v / √5
Step-by-step explanation:
Solution:-
- We have a satellite of mass ( m ) that orbits the earth of mass ( M ). The radius of orbit is ( r ) : center of earth - to - center of satellite radial distance.
- The satellite orbits the Earth with constant tangent velocity ( v ). The velocity ( v ) is a function of massive body ( M ) about which the smaller body orbits and orbital radius ( r ).
- The formulation is given by:
Where,
G: The universal gravitational constant
- We are to compare the orbital speeds by changing some of the parameters in the above relation.
- The effect on the orbital speed ( v_orbit ) by increasing the orbital radius to ( 5r ) can be evaluated using the given relation. Such that:
- Now take the ratio of initial orbital speed to the increased orbital radius ( 5r ):
answer : D
A. (6 × 7) + 6 = 48
Associative property of multiplication . Here we have +6 . there is a + sign inbetween. so it does not comes under Associative property of multiplication
B. 6 × (4 + 2) = 36
Here we have 4 +2 . there is a + sign inbetween. so it does not comes under Associative property of multiplication
C. (6 + 4) × 2 = 20
Here we have 6 + 4 . there is a + sign inbetween. so it does not comes under Associative property of multiplication
D. (6 × 4) × 2 = 48
Here we have 6 times 4 times 2. so it comes under Associative property of multiplication
The X (1) axis represents the number of hours, and the Y (75) axis represents the number of dollars. When 0 hours are passed, 0 hours are payed (0,0) 1 hour 75 dollars are payed (1, 75) 2 hours 150 dollars is payed (2, 150) and so on
The value of equation when n = 3 is 50
<em><u>Solution:</u></em>
<em><u>Given equation is:</u></em>
We have to find the value of equation when n = 3
By plugging in n = 3 in given equation we can find the value of given equation
<em><u>Substitute n = 3 in given equation</u></em>
Thus the value of equation when n = 3 is 50
