Answer:
Mechanical vs. Quartz Watch Movements
Mechanical watch movements are powered by gears and springs. They're autonomous little machines without the need for electric power sources, whereas quartz watches are powered by batteries that vibrate little crystals.
Answer:
A would definately be the correct answer
Explanation:
Answer:
(A) Force on the object will be 58.85 N
(B) Apparent weight will be equal to 57.21 N
Explanation:
We have given mass of Neptune m = 1026 kg
Radius R = 25000 Km
Time period = 16 hour
We know that 1 hour = 3600 sec
So 16 hour = 16×86400 = 57600 sec
Acceleration due to gravity at north pole of Neptune
(A) Mass of the object m = 5.5 kg
So gravitational force on the object
(B) Velocity will be equal to
Apparent weight of the object will be equal to
