Option (ii) B is the correct option. The object on the moon has greater mass.
To resolve this, utilize the formulas Force = Mass * Acceleration.
The equation can be used to find the mass given the force in Newtons, using 9.8 m/s² for the acceleration of gravity of the earth and 1.6 m/s² for the moon.
Calculating the mass on earth:
30 N = 9.8 m/s² * mass
This results in a mass of 3.0 kg for the object on Earth.
Calculating the mass of the moon:
30 N = 1.6 m/s²2 * mass
Thus, the moon's object has a mass of 19. kg.
This can be explained by the fact that the earth has a stronger gravitational pull than the moon, producing more force per kilogram of mass. As a result, the moon's mass must be bigger to produce the same amount of force at a lower acceleration from gravity (1.6 m/s² vs. 9.8 m/s²).

Answer:
a=0.555m/s^2
Explanation:
First we find the distance traveled from the moment the engineer reacts to the car, assuming uniform movement
X=VT
X=(18)(0.45)=8.1m
then we find the distance at which the deceleration begins, which is obtained by subtracting the total distance with the inner result
X=300-8.1=291.9
finally we use the equation for constant acceleration
Vf=0 final speed
Vo=18m/s= initial speed
X=291.9m
(Vf^2-Vo^2)/2X=a
(0-18^2)/(2*291.9)=a
a=0.555m/s^2
Answer:
B. Earth's internal heat is thermal energy generated from molten rock under great pressure.
The identity of the element is determined by the number of protons
in the nucleus of each atom.
If two atoms have the same number of protons in their nucleii
(nucleuses) but different numbers of neutrons, then they're both
atoms of the same element, but their atomic masses are different,
and they're called isotopes of the element.
In the picture, atoms 'A' and 'B' each have 3 protons in the nucleus,
so they're both atoms of Lithium. But the number of neutrons is
different, so 'A' and 'B' are different isotopes of Lithium.
Also in the picture, atoms 'C' and 'D' each have 4 protons in the
nucleus, so they're both atoms of Beryllium. But the number of
neutrons is different, so 'C' and 'D' are different isotopes of Beryllium.
