Answer:
Speed of the runner during video interval is 6.49 m/s
Explanation:
According to the problem,
Number of frames recorded by camera in 1 second = 50
Time takes by camera to record 1 frame = (1/50) s
Time taken by camera to record 77 frames, t =
s
Distance covered by the runner during the video recording, d = 10 m
Speed, v = 
Substitute the values of d and t in the above equation.
v = 
v = 6.49 m/s
Friction is the force that acts on the opposite side of direction of force, thus it manages to decelerate an object, so it acts upward along the plane
Mirrors reflect light waves.
Answer: B. It demonstrates a behavior or particles.
Explanation: I took the test and got it right
Answer:
T = 98 N
Explanation:
The gravity of the earth is known to be 9.8 m/s²
Data:
- m = 10 kg
- g = 9.8 m/s²
- T = ?
Use formula:
Replace and solve:
The tension in the rope is <u>98 Newtons.</u>
