The tension in the string corresponds to the gravitational attraction between the Sun and any planet.
The correct statements are that the speed decreases as the distance decreases and speed increases as the distance increases for the same time.
Answer:
Option A and Option B.
Explanation:
Speed is defined as the ratio of distance covered to the time taken to cover that distance. So Speed = Distance/Time. In other words, we can also state that speed is directly proportional to the distance for a constant time. Thus, the speed will be decreasing as there is decrease in distance for the same time. As well as there will be increase in speed as the distance increases for the same time. So option A and option B are the true options. So if there is decrease in the distance due to direct proportionality the speed will also be decreasing. Similarly, if the distance increases, the speed will also be increasing.
The acceleration due to gravity only points downward with magnitude g. The angle of the projectile doesn't matter.
Answer: 98 millimeters
Explanation:
Since angle VTY is congruent to angle VTK, segment TY bisects angle VTK. Since Y is on segment VK, between V and K, we can use the Angle Bisector Theorem, which states that
(1)
Since x= VK = VY + YK, we need to obtain VY since YK = 68.
VY is obtained by multiplying the denominator YK on both sides of equation (1). So,
Hence,
x = VK = VY + YK
x = 30 + 68
x = 98 millimeters
