Answer:
Towards the center of the circle
Explanation:
When an object is moving in uniform circular motion, it means that it is moving at a constant speed in a circular path.
In order to follows a circular path, the particle must have a net force acting on it, that it makes it constantly changing direction - and therefore, causing an acceleration - and this force is called centripetal force.
The direction of this centripetal force is always towards the centre of the circular path.
The nature of the centripetal force is always different, depending on the situation. For instance: for a satellite orbiting the Earth in circular motion, the centripetal force is provided by the force of gravity. For a car moving round a curve, the centripetal force is provided by the force of friction between the tyres and the road.
The magnitude of the centripetal force is given by
where
m is the mass of the object
v is its speed
r is the radius of the circle
Iron rich minerals in rock pointed in one direction the switch to the exact opposite direction. I'd say that what supports this idea is that Earth's magnetic field goes through pole reversals.<span>

Answer:
V = 10581.59 V
Explanation:
To solve this problem, we have to take into the relation between the kinetic energy of an electron and the energy generated by the potential difference of an electric field. This relation is given by
where m is the mass of the electron, v is the velocity of the electron, e is the electric charge and V is the potential difference that accelerated the electron.
By taking V from the last expression we have:
where we have taken that
me = 9.1*10^(-31) Kg
e = -1.6*10^(-19) C
v = 6.1*10^(7)
I hope this is useful for you

Answer:
g = 0.98 m
Explanation:
given data:
upper portion weight 438 N and its center of gravity is 1.17 m
upper legs weight 144 N and its center of gravity is 0.835 m
lower leg weight 88 N and its center of gravity is 0.270 m
position of center of gravity of whole body can be determine by using following relation
where 
is mass of respective part and 
is center of gravity
g = 0.98 m
