Calculate the kinetic energy of a
30 g bullet fired at 200 m/s.

Step 1: Identify the formula needed to solve this problem.

The formula for kinetic energy (KE) is:

KE = 1/2m~v^2

m = mass

v = velocity

Step 2: Make a list of the values given in the question.

mass (m) = 30 g

velocity (v) = 200 m/s

[tex] \frac{1}{2} m {v}^{2} \\ \frac{1}{2} \times 30 \times {200}^{2} \\ 15 \times 40000 \\ = 600000[/tex]

Answer:

6 × 10⁵ J

Explanation:

Kinetic Energy of a moving mass is defined as, half of the product of it's mass and the square of it's velocity.

[tex] \boxed{ \mathsf{K.E. = \frac{1}{2} m( {v})^{2} }}[/tex]

[tex] \implies\mathsf{K.E. = \frac{1}{2} \times 30 \times ( {200})^{2} }[/tex]

[tex] \implies\mathsf{K.E. = 15 \times 4 \times {10}^{4} }[/tex]

[tex] \implies\mathsf{K.E. = 60 \times {10}^{4} }[/tex]

[tex] \implies \underline{\mathsf{K.E. = 6 \times {10}^{5} J }}[/tex]

7)When a body cell divides through the process of mitosis, the chromosomes in the daughter cells *

are formed when chromosomes from the parent cell cross over.
are identical to the chromosomes of the parent cell.
represent only the healthiest chromosomes from the parent cell.
represent only half of the chromosomes in the parent cell.

8)Before a cell enters mitosis, what happens to the genetic information in that cell? *

The information is duplicated.
The information is selectively mutated.
The information is halved.
The information is completely changed.

9)Which of the following best describes how mitosis is related to cellular reproduction? *

Mitosis is a phase in asexual reproduction that results in the formation of similar, but not identical, nuclei in the daughter cells.
Mitosis is a phase in asexual reproduction that results in the formation of identical nuclei in the daughter cells.



Mitosis is a phase in sexual reproduction that results in the formation of similar, but not identical, nuclei in the daughter cells.
Mitosis is a phase in sexual reproduction that results in the formation of identical nuclei in the daughter cells.

10)Which of the following occurs during the interphase stage of the cell cycle? I. DNA is replicated. II. The cell divides. III. The cell grows in size. *

II only

I, II, and III
I and II only

11)A diagram of the cell cycle is shown below. Which of the following statements best describes what happens during the S phase of the cell cycle? *


The cell's chromosomes separate.
The contents of the cell divide.
The cell's DNA is replicated.
The cell prepares for mitosis.

12)At a point during a cell's development, it begins to differentiate. How does differentiation occur? *

Certain genes are turned on and others are turned off; this action produces adult cells that are specialized
As a cell matures, genes that are not necessary to its function are ejected out of the cell through active transport.
The number of chromosomes in the cell is reduced by half; this action triggers the specialization of the cell.
A developing cell's function is determined by the number of organelles that are contained in the cell.

Tectonic plate movement is the reason why northern California has a very different landscape than southern California. Two different tectonic plates, each moving in different directions, border the western side of the North American Plate. Use the map to identify the two tectonic plates that border the North American Plate to the west.

Part B
On the map, take a close look at the boundary along southern California and Mexico’s Baja California Peninsula. The arrows on the map show the direction and speed of the plates along this boundary in millimeters per year. Based on the speed and direction of the arrows, identify the type of plate boundary at this location. Which landforms or events are likely to occur there as a result? (Hint: It may be helpful to model the motion of the plates using your hands or pieces of paper.)
