The nuclear division processes of mitosis and meiosis occur during cell division. During mitosis, body cells are divided, while during meiosis, s3x cells are divided. At mitosis, a cell divides once; at meiosis, it divides twice.

A circular coil of radius 5.0 cm and resistance 0.20 Ω is placed in a uniform magnetic field perpendicular to the plane of the c

DedPeter [7]

Answer:

The induced current in the coil at the time 2 s is 0.00263 A

Explanation:

The equation for induced emf is equal to:

$\epsilon =-\frac{d}{dt} (BAcos\theta )$

Where

B = magnetic field

A = area

θ = angle

$\epsilon =-Acos0\frac{d}{dt} B\\\epsilon =-(\pi r^{2} )\frac{d}{dt} (0.5e^{-0.2t} )\\\epsilon =0.1 (\pi r^{2} )e^{-0.2t}$

For t = 2 s

$\epsilon =0.1*\pi *0.05^{2} *e^{-0.2*2} =5.26x10^{-4} V$

The induced current is:

$I=\frac{\epsilo }{R} =\frac{5.26x10^{-4} }{0.2} =0.00263A$

What acceleration of a 45 kg mass pushed with 15 N of force?

Hitman42 [59]

Explanation:

Fnet = ma.

Assume that there is no resistance acting on the mass. Therefore a = 15N / 45kg = 0.33N/kg or 0.33m/s^2.

What volume In liters is a cube 20cm on a side? If the cube is filled with water what is the mass of the water?

frez [133]

1 liter = 1000 cm^3
20cm * 20cm * 20cm = 8000 cm^3
8000/1000 = 8 liters

Since 1ml of water = 1 cm^3 = 1 grams
8 liters = 8000 grams = 8 kilograms
