What is the resistance in a circuit that carries a 0.75 A current when powered by a 1.5 V battery?

2 answers:

The formula to use is: I = ( ΔV / R )
Once you solve for R, your new formula would be: R= ( ΔV / I )
Plug in your values to get: R = (1.5V / .75A )
Finally, R = 2Ω

Answer : The resistance in the circuit is, 2 ohm

Solution : Given,

Voltage = 1.5 V

Current in the circuit = 0.75 A

According to the Ohm's law, the current passing through the conductor is directly proportional to the voltage and is inversely proportional to the resistance.

Formula used :

$V=I\times R$

where,

V = voltage

I = electric current

R = resistance

Now put all the given values in the above formula, we get

$1.5V=(0.75A)\times R$

$R=2ohm$

Therefore, the resistance in the circuit is, 2 ohm

zalisa [80]

Answer:

(a) t = 1.67 s

(b) s₂ = 45 m

Explanation:

Here, we use the formula:

s = vt

FOR Seth:

s₁ = v₁t₁

where,

s₁ = distance covered by Seth

v₁ = speed of Seth = 9 m/s

t₁ = time taken by Seth

FOR Mack:

s₂ = v₂t₂

where,

s₂ = distance covered by Mack

v₂ = speed of Mack = 27 m/s

t₂ = time taken by Mack

since, initially Mack is 30 m behind Seth. Therefore,

(a)

s₂ = s₁ + 30 m

using formulae:

v₂t₂ = v₁t₁ + 30 m

but, the time of catching is same for both (t₁ = t₂ = t)

v₂t = v₁t + 30 m

using values:

(27 m/s)t - (9 m/s)t = 30 m

t = (30 m)/(18 m/s)

t = 1.67 s

(b)

s₂ = v₂t

using values:

s₂ = (27 m/s)(1.67 s)

s₂ = 45 m

what happens when light travels from one medium to another with a different index of refraction at a zero degree angle of incide

zaharov [31]

Answer:

No Refraction takes places

Explanation:

When light travels from one medium to another at an angle of incidence 0 degree then no refraction takes place .

It is because according to Refraction law

$n_{i}$ sini = $n_{r}$ sinr

where $n_{i} ,n_{r}$ are the refractive index of medium of incidence and medium of refraction .

When i = 0 , left side of the equation becomes 0 and thus r (angle of refraction) must be zero. So No refraction takes place

Lelu [443]

Answer:

The greatest acceleration the man can give the airplane is 0.0059 m/s².

Explanation:

Given that,

Mass of man = 85 kg

Mass of airplane = 109000 kg

Distance = 9.08

Coefficient of static friction = 0.77

We need to calculate the greatest friction force

Using formula of friction

$F=\mu mg$

Where, m = mass of man

g = acceleration due to gravity

Put the value into the formula

$F = 0.77\times85\times9.8$

$F= 641.41\ N$

We need to calculate the acceleration

Using formula of newton's second law

$F = ma$

$a=\dfrac{F}{m}$

Put the value into the formula

$a=\dfrac{ 641.41}{109000}$

$a=0.0059\ m/s^2$

Hence, The greatest acceleration the man can give the airplane is 0.0059 m/s².
