Huge masses of rock rise from deep inside Earth, travel along its surface and then sink back down. The process is known as plate tectonics. We rarely see those changes as they happen. Yet plate tectonics affects everyone.
Answer:
Explanation:
Given that,
Basket ball is drop from height
H=10m
It is dropped on planet mass
And the acceleration due to gravity on Mars is given as
g= 3.7m/s²
Time taken for the ball to reach the ground
Initial velocity of the body is zero
u=0m/s
Using equation of motion: free fall
H = ut + ½gt²
10 = 0•t + ½ × 3.7 ×t²
10 = 0 + 1.85t²
10 = 1.85t²
Then, t² =10/1.85
t² = 5.405
t = √ 5.405
t = 2.325seconds
So the time the ball spend on the air before reaching the ground is 2.325 seconds
When the original resistor is replaced with 3 times more resistive material, the resistance of the circuit increases by factor of 3 and the current flowing in the cirucit decreases by a factor 3.
<h3>
Ohm's law</h3>
Ohm's law states that, the current flowing in a conductor is directly proportional to the potential across the conductor.
V = IR
where;
- I is the current in the circuit
- V is voltage
- R is the resistance
When the resistance increases, the current flowing in the circuit decreases.
When the original resistor is replaced with 3 times more resistive material, the resistance of the circuit increases by factor of 3 and the current flowing in the cirucit decreases by a factor 3.

The particles that are usually in a much higher energy usually comes from the magnetic field of the Earth in which it is trapped consisting the Van Allen radiation belts. In addition to that, these radiation belts are somewhat essential because it protects satellites orbiting the Earth from the Sun's high energy radiation.
The isotopes contribute to the average atomic mass based on their abundance. The result is that the "average" mass for the atoms of an element is dictated by the most abundant or common isotope. The average atomic mass for carbon is 12.0107 amu.
The atomic mass as displayed on the periodic table is a weighted average relative atomic mass of the naturally occuring isotopes of that element.
An isotope is an element with the same number of protons but a different number of neutrons
For example - Carbon naturally occurs in isotopes C12, C13 and C14 with abundances of 98.9% 1.1% and 'trace' respectively.
the average mass is then calculated by 12*98.9%+13*1.1% = 12.01g/mol
