Answer:
Its Answer is 10 s.
Explanation:
As acceleration is defined as time rate of change of velocity. So,
a = 
÷ t
2 = (20 - 0 ) ÷ t
2 = 20 ÷ t
t = 20 ÷ 2
t = 10 s
We have put initial velocity as zero because body is starting from rest.

Graduated cylinders have numbers on the side that help you measure volume
Cations are formed by losing electrons
Cations are basically positive ions
It's not lose or gain protons because atoms can't lose or gain protons. The protons don't move.
It's not gain electrons because electrons are negative. More electrons=more negative
If you can't remember cations are positive
CAT-ions are PAWS-itively charged
Answer:
solar eclipse mostly occurs when the moon gets between Earth and the sun, and the moon casts a shadow over Earth. A solar eclipse can only take place at the phase of new moon, when the moon passes directly between the sun and Earth and its shadows fall upon Earth's surface.
Answer:
3 : 08 : 10.9
Explanation:
assuming a 12 hour clock
angular velocity of the hour hand is 2π/(3600(12)) rad/s
angular velocity of the minute hand is 2π/3600 rad/s
difference is 2π/3600 - 2π/(3600(12)) = 11(2π/(3600(12)) rad/s
45° = π/4 radians
This angle is covered in a time of
π/4 rad / 22π / (3600(12)) = 900(12) / 22 = 490.909090... s
or about 8 minutes 10.9 s
