How are mitosis and meiosis similar?
fiasKO [112]
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.

A skateboard has a mas of 450g if it travels at 7m/s what is te momentum
Elza [17]

Answer:

Momentum (P)= 3.15Kg.m/s

Explanation:

Because momentum by definition is the product of mass and velocity, therefore, it's calculated by the formula;

P=mv,,,

where 'P' Is the momentum

'm' is mass in Kilograms, note that mass should be in Kilograms, therefore the 450grams should be converted to kilograms by dividing it with a 1000, i.e (450g×1kg/1000g)= 0.45kg, and now you can substitute in the formula because you have everything you need to find momentum in the right si units.

so P=mv

P=0.45Kg×7m/s

P=3.15Kg.m/s

Why isn’t our constitution ( and our country) in a constant state of adjustment and readjustment
madam [21]

The constitution and the country aren't in a constant state of adjustment and readjustment because it has strong and logical ideological bases that encompass most of society's issues over time.

The constitution was written on a democratic ideological basis inspired by the European Enlightenment revolution of thought. These principles have contributed to the construction of American social logic.

Therefore, the constitution and the country have not needed major readjustments or adjustments since their creation because the country has been built on solid and well-defined ideological bases that are projected into the future with a social logic.

There are two blocks: one large one initially at rest, and a smaller one, initially moving to the right withsome speed. The smal
KATRIN_1 [288]

Answer:

Explanation:

Let the initial velocity of small block be v .

by applying conservation of momentum we can find velocity of common mass

25 v = 75 V , V is velocity of common mass after collision.

V = v / 3

For reaching the height we shall apply conservation of mechanical energy

1/2 m v² = mgh

1/2  x 75 x V² = 75 x g x 10

V² = 2g x 10

v² / 9 = 2 x 9.8 x 10

v² = 9 x 2 x 9.8 x 10

v = 42 m /s

small block must have velocity of 42 m /s .

Impulse by small block on large block

= change in momentum of large block

= 75 x V

= 75  x 42 / 3

= 1050 Ns.
