First year biology.
The answer is D. Each process results in the formation of Daughter Cells, except the process of Meiosis results in half the number of Daughter Cells, where Mitosis has Daughter Cells identical to the Parent Cell.
Answer:
Vd = 1.597 ×10⁻⁴ m/s
Explanation:
Given: A = 3.90×10⁻⁶ m², I = 6.00 A, ρ = 2.70 g/cm³
To find:
Drift Velocity Vd=?
Solution:
the formula is Vd = I/nqA (n is the number of charge per unit volume)
n = No. of electron in a mole ( Avogadro's No.) / Volume
Volume = Molar mass / density ( molar mass of Al =27 g)
V = 27 g / 2.70 g/cm³ = 10 cm³ = 1 × 10 ⁻⁵ m³
n= (6.02 × 10 ²³) / (1 × 10 ⁻⁵ m³)
n= 6.02 × 10 ²⁸
Now
Vd = (6A) / ( 6.02 × 10 ²⁸ × 1.6 × 10⁻¹⁹ C × 3.9×10⁻⁶ m²)
Vd = 1.597 ×10⁻⁴ m/s

<span>Acceleration = (change of speed) / (time for the change)
Change in speed = (30 - 0) = 30 m/s.
Time for the change = 8 sec.
Acceleration = 30/8 = 3.75 m/s per second.

The answer is A. In the rack, the bowling ball has only potential energy. As it knocks pins down, its potential energy has decreased, while its kinetic energy has increased.
Answer:
They will NOT fall at the same rate because of the force. Hope this helps! Have a blessed day!
