What is the equivalent resistance for a parallel circuit that has two resistors: 18.0 ohms and 23.5 ohms?

With only two resistors in parallel, it's relatively easy
to calculate their combined equivalent resistance.

                       R  =  (their product) / (their sum)

                           =  (18Ω x 23.5Ω) / (18Ω + 23.5Ω)

                           =           (423Ω²)  /  (41.5Ω)

                           =    10.2 Ω

Particle q₁ has a charge of 2.7 μC and a velocity of 773 m/s. If it experiences a magnetic force of 5.75 × 10⁻³ N, what is the s
Ne4ueva [31]
The intensity of the magnetic force F experienced by a charge q moving with speed v in a magnetic field of intensity B is equal to
F=qvB \sin \theta
where \theta is the angle between the directions of v and B.

1) Re-arranging the previous formula, we can calculate the value of the magnetic field intensity. The charge is q=2.7 \mu C=2.7 \cdot 10^{-6}C. In this case, v and B are perpendicular, so \theta=90^{\circ}, therefore we have:
B= \frac{F}{qv \sin \theta} = \frac{5.75 \cdot 10^{-3}N}{(2.7 \cdot 10^{-6}C)(773m/s)\sin 90^{\circ}}=2.8 T

2) In this second case, the angle between v and B is \theta=55^{\circ}. The charge is now q=42.0 \mu C=42.0 \cdot 10^{-6}C, and the magnetic field is the one we found in the previous part, B=2.8 T, so we can find the intensity of the force experienced by this second charge:
F=qvB \sin \theta=(42\cdot 10^{-6}C)(1.21 \cdot 10^3 m/s)(2.8 T)(\sin 55^{\circ})=0.12 N

Ow much charge flows from a 12.0 v battery when it is connected across a completely discharged 18.0 μf capacitor
Trava [24]
The equation Q=CV (Charge = product of Capacitance and potential difference) tells us that the maximum charge that can be stored on a capacitor is equal to the product of it's capacitance and the potential difference across it. In this case the potential difference across the capacitor will be 12.0V (assuming circuit resistance is negligable) and it has a capacitance of 18.0μf or  18.0x10^-6f, therefore charge equals (18.0x10^-6)x12=2.16x10^-4C (Coulombs).

You buy a plastic dart gun, and being a clever physics student you decide to do a quick calculation to find its maximum horizont
Scilla [17]

Answer:

R_{max} = 51.84 m

Explanation:

When we shoot the dart upwards the time taken by the dart to go straight up and again come back is given as

t = 4.6 s

here we can say

\Delta y = 0 = v_i t + \frac{1}{2}at^2

0 = v_i t - \frac{1}{2}(9.8)t^2

put t = 4.6 s then we have

v_i = 22.54 s

Now in order to find the maximum range we can say

R = \frac{v^2 sin2\theta}{g}

so in order to have maximum range we can say

\theta = 45 degree

R_{max} = \frac{v^2}{g}

R_{max} = \frac{22.54^2}{9.8}

R_{max} = 51.84 m

What are some possible injuries that can occur as a result of anabolic steroid use?
Natali5045456 [20]
Most data on the long-term effects of anabolic steroids in humans come from case reports rather than formal epidemiological studies. Serious and life-threatening adverse effects may be underreported, especially since they may occur many years later. One review found 19 deaths in published case reports related to anabolic steroid use between 1990 and 2012; however, many steroid users also used other drugs, making it difficult to show that the anabolic steroid use caused these deaths.39 One animal study found that exposing male mice for one fifth of their lifespan to steroid doses comparable to those taken by human athletes caused a high frequency of early deaths
