Explanation:
Convergent boundaries (where plates collide) and divergent boundaries (where plates split apart).
Answer:
B
Explanation:
In this process on merry go round there is not any external torque so angular momentum will be conserve. Mass is always conserved.
Answer:
16,506 ft²
Explanation:
There are different ways you can divide the area using rectangles and circles. One way is to find the area of the entire width and length, then subtract the empty areas in the corners.
If we take the empty areas and put them together, we find their area is the area of a square minus the area of a circle.
A = (2r)² − πr²
A = 4r² − πr²
A = (4 − π) r²
So the area of the rink is:
A = WL − (4 − π) r²
A = (85)(200) − (4 − π) (24)²
A ≈ 16,506 ft²
In the circuit, the total current is 60 A and the voltage is 240 V. If R1
resistance is 20 Ω, then the R2 resistance would be 5 Ω
<h3>What is resistance?</h3>
Resistance is the obstruction of electrons in an electrically conducting material. The SI unit of the resistance is Ohm
The mathematical relation for resistance can be understood with the help of the empirical relation provided by Ohm's law.
V=IR
where V is the voltage
I is the current
R is the resistance
For the given problem V= 240 V and I = 60 A
R = V/I
R =240/60
R =4 Ω
For calculating equivalent resistance in parallel combination.
1/Re = 1/R1 + 1/R2
1/4 = 1/20 + 1/R2
R2 = 5 Ω
Thus , the R2 resistance would be 5 Ω, therefore the correct answer is option B.
