It depends on the circuit. Sometimes it becomes a bit weaker, sometimes it stays the same.
Answer:
the voltage drop across this same diode will be 760 mV
Explanation:
Given that:
Temperature T = 300°K
current = 100 μA
current = 1 mA
forward voltage = 700 mV = 0.7 V
To objective is to find the voltage drop across this same diode if the bias current is increased to 1mA.
Using the formula:
where;
= 0.7
Suppose n = 1
Then;
760 mV
Thus, the voltage drop across this same diode will be 760 mV
Responda:
30.0066 m
Explicação:
Dado o seguinte:
Temperatura (t1) = 5 ° C
Comprimento (L1) = 30m
Temperatura (t2) = 25 ° C
Coeficiente de expansão linear do aço (α) = 11 × 10 ^ -6 ° C-1
Lembre-se:
Expansibilidade linear (α):
Alteração do comprimento / comprimento original (diferença de temperatura)
α = [ΔL / L1 (ΔT)]
α = [(L2 - L1) / L1 (T2 - T1)]
α * L1 (T2 - T1) = (L2 - L1)
11 × 10 ^ -6 * 30 (25-5) = L2 - 30
11 × 10 ^ -6 * 30 (20) = L2 - 30
11 × 10 ^ -6 * 600 = L2 - 30
6600 × 10 ^ -6 = L2 - 30
L2 = 0,0066 + 30
L2 = 30.0066m
When a car hits you in a rear end collision, the car initially has a momentum going in one direction. This causes your car to move in the same direction that car was moving even if you were at rest. So, for conservation of momentum, you initially have momentum going in the east direction for example, after the collision, you will have a change in momentum which causes you to have a velocity in the west direction. This is because you are initially at rest and then there is a sudden change in velocity so when you speed up, that momentum causes you to move backwards. If you don't have a properly adjusted neckrest you could may experience whiplash.
Answer:
17.00 N
Explanation:
Given that the x-component of a vector is 17, and the angle between the vector and the x-axis is 46 degrees
The magnitude of the vector will be calculated by first resolving the vector into x component and y component.
X - component
17cos46 = 11.809
Y component
17sin46 = 12.229
We will find the resultant vector by using pythagorean theorem
R = sqrt ( X^2 + Y^2 )
R = sqrt ( 11.809^2 + 12.229^2 )
R = sqrt ( 288.995 )
R = 16.999
R = 17.00 N
Therefore, the magnitude of the vector is 17 .00N
