Avertical spring has a spring constant of
100. newtons per meter. when an object is
attached to the bottom of the spring, the spring
changes from its unstretched length of 0.50 meter
to a length of 0.65 meter. the magnitude of the
weight of the attached object is
(1) 1.1 n (3) 50. n
(2) 15 n (4) 65 n

Blank liquids and gases exert a buoyant force on objects placed in them

Is there a point between a 10 nc charge and a 20 nc charge at which the electric field is zero?

According to newton’s law of universal gravitation, which statements are true? as we move to higher altitudes, the force of gravity on us decreases. as we move to higher altitudes, the force of gravity on us increases. as we gain mass, the force of gravity on us decreases. as we gain mass, the force of gravity on us increases. as we move faster, the force of gravity on us increases.
