Answer:
Explanation:
Time taken to complete one revolution is called time period.
So, Time period, T = 1 s
Diameter = 1.6 mm
radius, r = 0.8 mm
Let the angular speed is ω.
The relation between angular velocity and the time period is
ω = 2 x 3.14 = 6.28 rad/s
The relation between the linear velocity and the angular velocity is
v = r x ω
v = 0.8 x 10^-3 x 6.28
v = 0.005 m/s
Answer:
D
Explanation:
planting trees because they store these gases and turn it into oxygen
Earths moon is said to be formed way back when the earth was still a molten ball of lava. Something huge crashed into it, causing a piece to fly off. Due to earths gravity, the piece cooled and began orbiting us.
Lunar eclipses are more common because the moon and sun are not likely to align rather than the planets aligning.
C It will increase. Static fiction is proportional to the force that gravity applys to the body. Increasing the weight the fiction increases, so does the force required to move the body
