Answer:
-True - True - true - false -false - false
Explanation:
- True The flow depends only on the charge into the surface, not on the relative position
- True The two vectors are radial, so their relative direction do not changes
- True It just depends on the charge inside
- False, it only depends on the charge, not on the form from the integration surface
- False, because if it has a load inside it can be considered in the center, but if the load is outside the flow lines change direction with respect to the surface
- False The flow depends only on the load inside, not on its position
Answer:
C. It is radiation leftover from the Big Bang
Equation 1 :
m1 : m1a =T
Equation 2:m2 : m2a= F - T
Adding 1 and 2a=0.073
Placing in equation 1
we get T = 218.18N
Answer: acceleration due to gravity of planet a would be twice that of planet b. Given that the radius are thesame.
Explanation:
Acceleration due to gravity is as a result of the gravitational force of attraction of a planet to its centre.
g = GM/r^2
Where;
g = acceleration due to gravity
G = gravitational constant
M = mass of planet
r = radius of planet
Given that the two planet have the same radius, if the mass of planet a is twice the mass of planet b the the acceleration due to gravity of planet a would be twice that of planet b, because acceleration due to gravity is directly proportional to the mass of the planet.
Kinetic energy is the energy possessed by a body while in motion. It is calculated by 1/2mv², where m is the mass of the body and v is the velocity.
Therefore, kinetic energy is dependent on both mass of the body and the velocity. An increase in mass increases the kinetic energy, an increase in velocity also increases kinetic energy of the body. Thus, doubling the mass and doubling the velocity will both increase the kinetic energy of the body.
