Answer:
option B
Explanation:
Radius of new planet,R' = 2R
Mass of the earth, M' = 2 M
R and M is the Radius and Mass of the earth.
Weight of the person on earth = 500 N
Weight of the person in the new planet = ?
We know acceleration due to gravity is calculated by using formula
now, acceleration due to gravity on the new planet
here acceleration due to gravity is half in new planet, so weight will also be half on the new planet.
Weight on the new plane is equal to 
= 250 N
correct answer is option B
Answer:
The first option, "The more mass an object has, the greater the gravitational pull.
"
Explanation:
Newton's Law of Gravity states that 
, where G is the gravitational constant, 
and 
are the masses of the two objects, and <em>r</em> is the distance between the objects' centers. Because the objects' masses are in the fraction's numerator, they are directly proportional to 
, and increasing the mass of one or both objects increases the gravitational pull.
Please have a great day! I hope this helps you understand the question!
Explanation:
Usually when we think of waves, we think of transverse waves. These are waves where points move up and down perpendicular to the motion of the wave. Examples include water waves, whipping a rope, or even doing the "wave" in a crowd. You can think of these as "two dimensional" waves.
Longitudinal waves are waves where points move left or right, parallel to the motion of the wave. In other words, there is compression and expansion of the medium. Examples include sound waves, or pulses in a slinky.
Answer:
For an atom to have a balanced charged, the number of protons shall be equal to the number of electrons of an atom. proton is the positive part of an atom whereas electrons are the negative part of an atom. Only if the number of protons will be equal to the number of electron, the atom will be able to be neutral.
If the number of electron will be more, then the atom will be negative. If the number of electron will be less, then the atom will be positive.
