Answer:

B. 1.7A

Explanation:

R = Resistance

I = Current

V = Voltage (potential difference)

22+4.5 = 26.5

45/26.6= 1.698

Round 1.698 to the nearest hundredth: 1.7

The current of the circuit is 1.7

Answer:

According to Ohm's law ,

V = IR

where ,

V = Potential difference

I = Current flowing

R = Total resistance

here ,

R _{t} = 22Ω + 4.5Ω = 26.5Ω

( since , the resistors are connected in series )

Using Ohm's Law ,

45 = I(26.5) \\  I =  \frac{45}{26.5}  \\  \\ I = 2.5A \: (approx.)

Therefore , option ( 1 ) is correct.

hope helpful~

Why does a lunar eclipse last for a few hours whereas a solar eclipse only lasts for a few minutes?
Aneli [31]

Answer:

The type and length of a lunar eclipse depend on the Moon's proximity to either node of its orbit. ... A total lunar eclipse can last up to nearly 2 hours, while a total solar eclipse lasts only up to a few minutes at any given place, due to the smaller size of the Moon's shadow.

Part A A uniform solid disk of radius 1.60 m and mass 2.30 kg rolls without slipping to the bottom of an inclined plane. If the
kifflom [539]

Answer:

Height will be 3.8971 m        

Explanation:

We have given that radius of the solid r = 1.60 m

Mass of the solid disk m = 2.30 kg

Angular velocity \omega =4.46rad/sec

Moment of inertia is given by I=\frac{1}{2}mr^2

Transnational Kinetic energy is given by KE=\frac{1}{2}mv^2 as we know that v = v=\omega r

So KE=\frac{1}{2}m(\omega r)^2

Rotational kinetic energy is given by KE_{ROTATIONAL}=\frac{1}{2}I\omega ^2=\frac{1}{2}\left ( \frac{1}{2}mr^2 \right )\omega ^2=\frac{1}{4}m(r\omega )^2

Potential energy is given by mgh

According to energy conservation

mgh=\frac{1}{2}m(\omega r)^2+\frac{1}{4}m(\omega r)^2

h=\frac{3r^2\omega ^2}{4g}=\frac{3\times 1.60^2\times 4.46^2}{4\times 9.8}=3.8971m

Which law states that absolute zero cannot be reached?
padilas [110]
The third law of thermodynamics,the principle of temperature.

This law states that the entropy at 0 is always equel to 0.
This means that it is impossible to cool down a perfect 0 or absolute 0(-273.15 C)
