Answer:
i = 1.2 [amp].
Explanation:
In order to find the current in the circuit, we must perform a sum of voltages equal to zero, around the mesh.
∑V = 0
Let's take the direction of the current as shown in the drawing Clockwise.
Note: The negative sign means that the current moves in a counterclockwise direction.
Answer:
The rate of change of the height is - 4 ft/s
Solution:
As per the question:
Height of the person, y = 5 ft
The rate at which the person walks away,
Distance of the spotlight from the wall, x = 40 ft
Now,
To calculate the rate of change in the height, of the person when, x = 10 m:
From fig 1.
xy = 200 (1)
Differentiating the above eqn w.r.t time t:
Thus
(2)
From eqn (1):
When x = 10 ft
10y = 200
y = 20 ft
Using eqn (2):
Answer:
Number :
Number is actually represents quantity.
Symbol :
Symbol is actually a character that shows the number.
Explanation:
Answer:
If we have large numbers (b is positive) or small numbers (b is negative), then this way ... 1, and V2i = 100 L, n2i = 5 + 2 + 1 = 8 in vessel 2. ... a good working substance in the barometer.
