Answer:
IS TWICE THAT OF THE GRAVITATIONAL FORCE BETWEEN THE SMALLER ASTEROID AND THE SUN
Explanation:
The equation for gravitational force is:
where G is the gravitational constant.
Given that distance remains constant, and the mass of the bigger asteroid is bigger, we can get the following relation:
Here we can see that multiplying the mass by 2 gives us 2 times the gravitational force for the bigger asteroid.
Thus, the gravitational force for the bigger asteroid and the sun is two times that of the smaller asteroid and the sun.
Answer:
(C)Direct kick
Explanation:
In a game of soccer (foot-ball) there are lots of rules involved in the game and there is penalty for each of the rules violated. Some of the rules include penalty kick, free kick, throw in, goal kick etc.
Free kick is of two types; direct kick and indirect kick.
Direct kick is awarded when a player outside 18 yards box violently or dangerously charges a opponent.
Indirect kick can be awarded when a goalkeeper inside 18 yards box commits certain offenses.
Therefore, the correction option is (C)Direct kick
Answer:
a. When the total displacement is -(A + B)
b. A + B = 1 m or -(A + B) = -11 m
c. 0 m
Explanation:
a. Under what circumstances can you end up back at your starting point?
If we have the displacement A and displacement B. The total displacement is A + B. We would end up at the starting point if we take a displacement -(A + B) from point B
b. What is the magnitude of the largest displacement you can end up from the starting point?
The maximum displacement we can obtain is when A and B are in the same direction. So A + B = 5 m + 6 m = 11 m or -A - B = -(A + B) = -11 m.
c. When A and B are perpendicular, what is the component of B in the direction of A?
Since A is perpendicular to B, the angle between A and B is 90°
So the component of B in A,s direction is Bcos90° = B × 0 = 0 m
