The buoyant force of an object which is submerged in water or any fluid is equal to the weight of the fluid displaced by an object.
why? the buoyant force goes up, and the gravitational pull goes down. <span />
Answer:
Less than
Explanation:
Speed of sound increases with density of the medium. Since wood is less dense than water, the speed of sound is lower in wood.
Answer:
(A) E = 0.84 N/C
(B) r = 4.74 meters
Explanation:
Given that,
Charge,
(a) The magnitude of electric field at a point 7.3 meters from this charge is given by :
E = 0.84 N/C
We know that electric field due to negative charge is inwards. So, the direction of electric field is towards the charge.
(b) Let at a distance of d meters the electric field have a magnitude of 2 N/C. It is given by :
r = 4.74 meters
Hence, this is the required solution.
