HELP PLEASE IM STUCK ON THESE QUESTIONS
Diano4ka-milaya [45]

Answer:

a = 10 m/s²

F = 2000 N

m = 8.57 Kg

Explanation:

1) What is the acceleration of a 40 kg object pushed with a force of 400 N?

Acceleration of object = ?

Mass of object = 40 Kg

Force on object = 400 N

Solution:

Formula:

F = ma

by putting values,

400 N = 40 Kg × a

a = 400 N/ 40 Kg   ( N = Kg.m /s²)

a = 10 m/s²

2) What is the force on an 800 kg rock being thrown at 2.5 m/s2?

Acceleration of object = 2.5 m/s²

Mass of object = 800 Kg

Force on object = ?

Solution:

Formula:

F = ma

by putting values,

F = 800 Kg × 2.5 m/s²

F = 2000 Kg. m/s²  ( N = Kg.m /s²)

F = 2000 N

3) What is the mass of a ball being rolled at 3.5 m/s2 from a 30 N force?

Acceleration of object = 3.5 m/s²

Mass of object = ?

Force on object = 30 N

Solution:

Formula:

F = ma

by putting values,

30 N = m ×  3.5 m/s²

m = 30 N / 3.5 m/s²   ( N = Kg.m /s²)

m = 8.57 Kg

PLEASE HELP GIVING 25 POINTS
prisoha [69]

Answer:

Explanation:

1. a. Interphase is the phase of the cell cycle in which a typical cell spends most of its life. During interphase, the cell copies its DNA in preparation for mitosis.

b. The third phase is anaphase. This phase only takes about 0.8 percent of the cell cycle to complete, which is the shortest time required out of all the phases. During anaphase the sister chromatids, or the two identical parts of a chromosome, are pulled apart to opposite ends of the cell by the spindle fibers.

2. Mitosis is important for three main reasons: development and growth cell replacement and asexual reproduction.

  • Development and growth. After meiosis has produced a gamete, and this has fused with another gamete to form an embryo, the embryo grows using mitosis. ...
  • Cell replacement. ...
  • Asexual reproduction.
