R1=3 ohms

Physics
1 answer:
brilliants [131]3 years ago
3 0

Answer: current I = 1.875A

Explanation:

If the resistors are connected in series,

Then the equivalent resistance will be

R = 6 + 18 + 15 + 9

R = 48 ohms

Using ohms law

V = IR

Make current I the subject of formula

I = V/R

I = 90/48

I = 1.875A

And if the resistors are connected in parallel, the equivalent resistance will be

1/R = 1/6 + 1/18 + 1/15 + 1/9

1/R = 0.166 + 0.055 + 0.066 + 0.111

R = 1/0.3999

R = 2.5 ohms

Using ohms law

V = IR

I = 90/2.5

Current I = 35.99A

A bullet with a mass of 0.1 kg is travelling at
mel-nik [20]

The block with the bullet lodged in the block is now travelling at 2.133 m/s.

<h3>What is momentum conservation principle?</h3>

When there is no external force acting on the system, the momentum remains conserved.

For inelastic collision, after collision both objects travel with common speed.

m1u1 + m2u2 =(m1 +m2)v

Substitute initial velocity of bullet u1 =320 m/s , initial velocity of block u2 =0, mass of bullet m1 = 0.1 kg and mass of block m2 = 14.9 kg.

Solve for the final velocity of bullet,

0.1 x 320 + 14.9 x 0 = (0.1 +14.9) x v

v = 2.133 m/s

Thus, the  block with the bullet lodged in block now travelling at 2.133 m/s.

A parallel network consist of three resistors 4 ohm, 8 ohm and 16 ohm .If the current in 8 ohm resistor is 3 A then what are the
Studentka2010 [4]

Answer:

If the resistors are in parallel they must all experience the same voltage drop.

R * I = V

8 * 3 = 24 V    (if i is 3 amps)

24V / 4 ohm = 6 amps

24V / 16 ohm = 1.5 amps

According to Dr. Ridel's Levels of Critical Thinking in Chapter 1, what level of critical thinking applies to your current statu
Karolina [17]

The levels of critical thinking classify people into six categories depending on their ability to reflect.

<h3>What is critical thinking?</h3>

This refers to the ability to analyze information, situations, etc. as well as apply, synthesize or evaluate the information learned.

<h3>What are the levels?</h3>

According to Dr. Ridel, the levels are:

  • Unreflective thinking: They do not reflect on information and lack the skills to have critical thinking.
  • Challenged thinker: This person knows critical thinking is important but has difficulties to have critical thinking.
  • Practicing thinker: This person has better-thinking abilities.
  • Advanced thinker: This person can critically think and has the skills to improve this process.
  • Master thinker: This person is in control of this process and shows superior thinking abilities.

A small, 150 g cart is moving at 1.60 m/s on a frictionless track when it collides with a larger, 5.00 kg cart at rest. After th
NemiM [27]

Answer:

Mass of larger cart will be 0.0213 m /sec

Explanation:

We have given mass of small cart m_1=150gram=0.150kg

Initial velocity of small cart v_{1i}=1.6m/sec

Mass of larger block m_2=5kg

Initial velocity of larger cart v_{2i}=0m/sec

After the collision velocity of smaller cart v_{1f}=-0.890m/sec

Now according conservation of momentum

m_1v_{1i}+m_2v_{2i}=m_1v{1f}+m_2v_{2f}

0.150\times 1.6+5\times 0=0.150\times -0.890+5\times v_{2f}

5\times v_{2f}=0.1065

v_{2f}=0.0213m/sec
