At Divergent boundary, Crust is created.
At Convergent boundary, Crust is destroyed.
At Transform boundary, Crust is neither created nor destroyed.
<h3>What occurs at Divergent, Convergent and Transform boundary?</h3>
A divergent boundary occurs when two tectonic plates move away from each other. At this boundary, new oceanic crust is created.
Convergent boundaries are those boundaries where two plates are pushing into each other. These boundaries are pushing one of the plates under the other and back into the mantle to melt.
Transform boundaries are places where plates slide sideways past each other. At this boundary, Crust is neither created nor destroyed.

Answer:
The factor of the diameter is 0.95.
Explanation:
Given that,
Power of old light bulb = 54.3 W
Power = 60 W
We know that,
The resistance is inversely proportional to the diameter.

The power is inversely proportional to the resistance.


We need to calculate the factor of the diameter of the filament reduced
Using relation of power and diameter

Put the value into the formula



Hence, The factor of the diameter is 0.95.

Hello!
Recall the period of an orbit is how long it takes the satellite to make a complete orbit around the earth. Essentially, this is the same as 'time' in the distance = speed * time equation. For an orbit, we can define these quantities: 
 ← The circumference of the orbit
 ← The circumference of the orbit 
speed = orbital speed, we will solve for this later
time = period 
Therefore: 

Where 'r' is the orbital radius of the satellite. 
First, let's solve for 'v' assuming a uniform orbit using the equation:

G = Gravitational Constant (6.67 × 10⁻¹¹ Nm²/kg²) 
m = mass of the earth (5.98 × 10²⁴ kg) 
r = radius of orbit (1.276 × 10⁷ m) 
Plug in the givens:

Now, we can solve for the period:
