Answer:
The direct current that will produce the same amount of thermal energy is 1.83 A
Explanation:
Given;
maximum current, I₀ = 2.59 A
The average power dissipated in a resistor connected in an AC source is given as;
Where;
The average power dissipated in a resistor connected in a DC source is given as;
where;
is direct current
Solve equation (1) and (2) together;
Therefore, the direct current that will produce the same amount of thermal energy is 1.83 A
Answer:
800cm3
Explanation:
This is a general gas law question
Which has the relationship P1V1/T1 = P2V2/T2
P1= P1 in kPa
T1 = T1 in K
V1= 800cm3
V2=?
P2= 2* P1
T2= 2*T1
The volume of gas after the changes (V2), making it as the subject of formula
V2= P1*V1*T2/P2*T1
V2 = P1 *800* 2T1 / 2P1 * T1 ; dividing accordingly, we have
V2 = 800cm3
<span>We know that v = u + at
He stops when the speed is zero; therefore
0 = 15 - 3.35 t
t = 4.48
It takes 4.48 seconds after the driver turns on the brake for him to stop.
We know
s = ut + (1/2)at</span>²<span>
s = 15*4.48 - *(1/2)(3.25)(4.48)</span>²<span>
s = 33.4 meters
The distance he travels before applying the brakes is:
s = 0.21 * 15
s = 3.15 m
The total distance he travels is:
3.15 + </span>33.4 = 36.55 meters
He will be able to stop in time.
The magnitude of this vector:
18.4 mi-28.7 mj is 34.09m
Given:
vector is
18.4 mi-28.7 mj
Magnitude =
This magnitude of a vector formula summarizes the distinct vector measures along the x-axis, y-axis, and z-axis. It is represented by the symbol |v|. A vector's magnitude is either a positive number or zero, and it can never be negative. Let us finally understand the magnitude of a vector formula by considering a few solved cases.
A vector's magnitude is equal to its length. The magnitude of the vector an is indicated by the symbol a. For further information on vector magnitude, see the introduction to vectors.
This article deduces formulas for the magnitude of vectors in two and three dimensions in terms of their coordinates. The magnitude formula for a two-dimensional vector a=(a1,a2)
