Answer: B
Explanation:
X-rays coming into Earth's system from space are absorbed by the atmosphere. Telescopes that processes X-rays, therefore, are placed in orbit above the atmosphere
The time period of the pendulum is affected by the acceleration due to gravity. The tension does not have any effect on the time period of the pendulum and also the mass of the bob does not effect the time period of the pendulum.
Hence, if the gravity increases then the time period of the pendulum will decreases and it will swing faster.
Answer:
The answer to your question is: C. -9.81 m/s²
Explanation:
A. 9.81 m/s² acceleration is considered positive when it goes to the center of the earth, so this option is incorrect.
B. 0 m/s² This option is incorrect because acceleration is 0 for a linear motion without acceleration.
C. -9.81 m/s² If a projectile goes to the sky, then the acceleration will be negative.
D. It is not constant. Acceleration is constant.
Answer:
the higher the ramp the less distance it will travel
