Answer:
the Prime Meridian is the planets line of 0 degrees longitude sometimes called the Greenwich Meridian or the international Meridian
the great circle of Earth with the latitude of 0 degrees
Answer:
frequency = velocity divided by wavelength
Explanation:
Answer:
a=0.5g ms^-2
Explanation:
Let tension be T
acceleration be a
g be gravitational acceleration 9.81ms^-2
They share same T and a
by force diagram the net force on m:
T-2.1g=2.1a
net force on M:
6.3g-T=6.3a
solve:
(T-2.1g)/(6.3g-T)=2.1a/6.3a
3T+T=12.6g
T=3.15g newton
3.15g-2.1g=2.1a
a=0.5g ms^-2

Assuming vertical acceleration of
, the speed after x seconds of falling is 
Answer:an electrical Current can be defined as the free flow of electrons through a circuit
