It means that if the mass of a mass is increased by some factor, and nothing else changes, then the weight of that mass increases by exactly the same factor.
Mass will remain constant on both planet, let mass of the object be "m".
let x be the <span>acceleration due to gravity on the surface of mars.
Weight of object on earth = m *g , where g is </span><span>acceleration due to gravity on the surface of earth
</span>⇒350 = m * 9.8
⇒m = 350 / 9.8 .............................equation(1)
Weight of object on mars = m * x , where x is acceleration due to gravity on the surface of mars
134 = m * x .............................equation(2)
putting the value of m from equation (1) in equation(2) , we get,
x = (134 * 9.8) / 350
⇒ x = 3.572 m/s²
Answer and explanation:
The right answer is b) "The excess charge has distributed itself evenly over the outside surface of the sphere".
The hollow metal sphere is a conductor. This means that charges can move freely over its surface. On the other side, a metal body act as an equipotential body. Once some charge is set and there is no voltage differential imprinted over the body, to keep being an equipotential body the charges must distribute evenly on the external surface. Must not exist charge in the volume, or would exist an electrical field and therefore a voltage differential. Also, the charge distribution in the internal surface must be null. If you apply gauss theorem with a gaussian sphere with a radius between the internal and external surface, knowing that field E is null, the enclosed charge must be null.
Answer:
Speed of both blocks after collision is 2 m/s
Explanation:
It is given that,
Mass of both blocks, m₁ = m₂ = 1 kg
Velocity of first block, u₁ = 3 m/s
Velocity of other block, u₂ = 1 m/s
Since, both blocks stick after collision. So, it is a case of inelastic collision. The momentum remains conserved while the kinetic energy energy gets reduced after the collision. Let v is the common velocity of both blocks. Using the conservation of momentum as :
v = 2 m/s
Hence, their speed after collision is 2 m/s.
