<h3>
Explanation:</h3>
<u>Step 1: Define</u>
Mass <em>m</em> = 1.50 × 10³ kg
Velocity <em>v</em> = 20 m/s east
Change in time Δt = 5.00 s
<u>Step 2: Find Magnitude</u>
- Substitute [Momentum]: P = (1.50 × 10³ kg)(20 m/s)
- Multiply: P = 30000 kg · m/s
<u>Step 3: Find Force</u>
<em>We use the Law of Conservation of Momentum to find our break force acting upon the car.</em>
- Substitute [Impulse]: 30000 kg · m/s = F(5.00 s)
- Rewrite: 30000 N · s = F(5.00 s)
- Divide 5 on both sides: 6000 N = F
- Rewrite: F = 6000 N
Since the car is deaccelerating, the break force would be towards the west direction (negative as east is our positive direction).
∴ F = -6000 N
Answer:
The order of steps for writing a chemical formula is 3, 2, 1, 5, 4
Explanation:
Balance the charges. Identify the negative ion and charge. Identify the positive ion and charge. Use the information in the ratio to write the chemical formula. Write the ratio of ions that balances the charges.
The order of steps for writing a chemical formula from the options above is:
3.) Identify the positive in and charge.
2.) Identify the negative ion and charge.
1.) Balance the charges.
5.)Write the ratio of ions that balances the charges.
4.) Use the information in the ratio to write the chemical formula.
