Answer:
Density is affected by volume and mass.
Explanation:
Density is defined as the quantity of mass per unit of volume, or expressed mathematically, d = m/v.
Answer:
4.3 * 10^28 kg
Explanation:
Given:
Period, T = 84s
Radius of satellite orbit, r = 8*10^6
Using the relation :
M = 4π²r³ / GT²
Where G = Gravitational constant, 6.67 * 10^-11
M = 4*π^2*(8*10^6)^3 / 6.67 * 10^-11 * 84^2
M = (20218.191872 * 10^18) / 47063.52 * 10^-11
M = 0.4295937 * 10^18 - (-11)
M = 0.4295937 * 10^29
M = 4.295937 * 10^28 kg
M = 4.3 * 10^28 kg
Mass of planet Nutron = 4.3 * 10^28 kg
1 kg of water = 1 L = 1 dm³
762 g of water = 762 cm³
Answer: c)• 2/3
Explanation:
Lets say q1 and q2 are two charges with r distance far apart.
So electrostatic force
F = (k q1 q2) / r²
as k = Coulomb's constant
Now
q1' = 2q1
q2' = q2/3
Therefore the new electrostatic force
F' = (k q'1 q'2) / r²
F' = (k 2q1 q2) / 3r²
F' = 2/3 [(k q1 q2) / r²]
so F' = 2/3F
New electrostatic force is 2/3F
Answer:
For instance, an object is moving and we can say that a force is acting or must have been acted upon to cause the state of motion. When force is applied, it changes the position of the object concerning time resulting in motion. The motion, in other words, is described as a change in speed or change in direction.
