Friction is a force that oppose other forces and can slow them down
what type of question is that man ?
Answer:
The energy of a vibrating string is transmitted through the bridge to the body of the violin, which allows the sound to radiate into the surrounding air. Both ends of a violin string are effectively stationary, allowing for the creation of standing waves.
Explanation:
Answer:
g = 0.85 m
Explanation:
g =
were; g is the acceleration due to Earth's gravity, G is Newton's gravitation constant (6.674 x N), M is the mass of the earth (5.972 x kg), and h is the distance of meteoroid to the earth.
h = 3.40 x R
= 3.40 x 6371 km
h = 21661.4 km
= 21661400 m
Thus,
g =
=
= 0.84944
g = 0.85 m
The acceleration due to the Earth's gravitation is 0.85 m.
Time = distance/speed, as you surely know. About the scientific notation, you just need to express the result as a number with one digit and the rest in decimal places with 10^... I can't see the exponents in your question and it's late here. Good luck! For instance, 6.434*10^3 ... I recall it takes about 5 hours, so you should get there, so about 5 * 3600 = 18000 seconds. Nice!
