Answer:
gravityis an invisible force that pulls objects toward each other. So, the closer objects are to each other, the stronger their gravitational pull is. Earth's gravity comes from all its mass .
Answer:
<em> The momentum of the body would be 13500 kg .m/sec</em>
Explanation:
What Momentum Entails
momentum is a property that is possed by all moving objects, it is a product of mass and velocity. A moving object has a magnitude which is the mass of the body and direction which is the velocity towards a certain direction, so it is a vector quantity
Step by Step Calculation
The momentum of a body can be gotten from the expression below;
p = m x v
where p is the momentum
m is the mass of the body = 1000 kg
v is the velocity = 13.5 m/sec
Given these parameters our momentum would be;
p = 1000 kg x 13.5 m/sec
p = 13500 kg . m/sec
Therefore the momentum of the body would be 13500 kg. m/sec
Answer:
The atomic number is the number over the symbol of the element in the periodic table and the atomic mass the number under it. An isotope is an atom with more or less neutrons than its regular form. a neon atom with mass number of 22 will have 12 neutrons in the nucleus and 10 protons, draw it with its 10 electrons. Two electrons go in the first level of energy and eight in the second. Draw a nucleus with 10 protons and 12 neutrons and an arc with 2 electrons around it and another arc with 8 electrons over the first arc.
Answer:
Explanation:
We have series and parallel combination of two resisters 
and 
.
Series combination is
and Parallel is 
Now dividing series equivalent resistance by parallel resistance gives us
.
Note! series Combination is simply superposition of two elements (resisters in this case ) in a circuit.
