<h3>Given -:</h3>
change in emitter current, ∆l(E) = 4 mA
change in collector current,∆I(C) = 3.5 mA
<h3>To find -:</h3>
value of B
<h3>Solution :-</h3>
∆I(E) = ∆I(C) + ∆l(B), here ∆l(B) is the change in base current.
4 = 3.5 + ∆l(B)
∆I(B) = 0.5 mA
<h3>Now, B = ∆l (C) ÷ ∆l (B)</h3>
B = 3.5 ÷ 0.5
B = 7.0
<h3>so, the value of A = 7.0</h3>
Answer:
the whole triangle is 180°
Step-by-step explanation:
63 + 68 = x
180° - x = y
y = the answer
Answer:
$43.00
Step-by-step explanation:
final price = marked price + tax
= marked price + (tax rate) · (marked price)
= (marked pric) · (1 + tax rate)
= $40.00 · 1.075
= $43.00
Answer:
90000 km
Step-by-step explanation:
1 hour = 3600 sec
distance = speed x time
= 25 km/s x 3600 s
= 90000 km
standard form = 9 x 10⁴
