Answer:
7. 1ml = 20 drops
325ml = 6500
( 325 x 20 = 6500)
there are 6500 drops in a pepsi can
8. not sure sorry ; (
9. 1 mile per hour = 88 feet per minute
45 miles per hour = 3960 feet per minute
( 88 x 45 = 3960)
there are 3960 feet per minute in 45 miles per hour
The fine horizontal scratches etched onto a bullet after it has been fired are called Striations.
<h3>What is Striations?</h3>
- Striations are the minute differences in the curve of the bullet's surface. The bullet and the gun barrel are the harder and softer materials, respectively, in firearms evidence.
- The striations left on the fired bullet are used as a comparison by firearm examiners.
- When a gun is discharged, the bullet blasts down the barrel where it strikes ridges and grooves, spinning and improving shot accuracy.
- These ridges cause striations in the bullet's soft metal by digging into it.
- An examiner analyses these distinctive markings to verify whether a given bullet was shot from a specific firearm.
- A barrel will produce individual markings in addition to a bullet's land and groove impressions as the projectile passes through.

Answer:
1 (pitcher), 2 (catcher), 3 (first baseman), 4 (second baseman), 5 (third baseman), 6 (shortstop), 7 (left fielder) 8 (center fielder), and 9 (right fielder)
Explanation:
There are nine fielding positions in baseball. Each position conventionally has an associated number, for use in scorekeeping by the official score
Answer:
Charge
Explanation:
Charge is a fundamental property of all matter. All matter has electrical and magnetic properties because the atoms that make up matter are held together by electromagnetic forces.
These charges are usually positive and negative charges. When these charges which make up an atom (positive and negative) are equal, the atom is said to be electrically neutral. When positive charge is greater than negative charge, the atom is said to positively charged. Also, if the number of negative charges are more in an atom, the atom is said to be negatively charged.
Answer:
d. 332 V
Explanation:
Given;
number of turns in the wire, N = 40 turns
area of the coil, A = 0.06 m²
magnitude of the magnetic field, B = 0.4 T
frequency of the wave, f = 55 Hz
The maximum emf induced in the coil is given by;
E = NBAω
Where;
ω is angular velocity = 2πf
E = NBA(2πf)
E = 40 x 0.4 x 0.06 x (2 x π x 55)
E = 332 V
Therefore, the maximum induced emf in the coil is 332 V.
The correct option is "D"
d. 332 V
