A mass of 25kg is acted on by two forces, one which is 15 N due east while the second one is 10N due north . The acceleration of the mass is.​

Answers

Answer:
0.72 m/s^2
33.7 degrees north of east

Found on quizlet.

The acceleration of the mass is 0.72m/s²

According to Newton's law of motion;

[tex]\sum F = ma[/tex]

Given the following parameters

mass m = 25kg

Get the resultant force

[tex]\sum F=\sqrt{10^2+15^2}\\\sum F = \sqrt{100 + 225}\\\sum F=\sqrt{325}\\\sum F= 18.03N[/tex]

From the formula:

[tex]a=\frac{\sum F}{m}\\a= \frac{18.03}{25}\\a= 0.72m/s^2[/tex]

Hence the acceleration of the mass is 0.72m/s²

Method of heat transfer which is  being studied by the student is thermal energy.

What is thermal energy?

Thermal energy is defined as a type of energy which is contained within a system which is responsible for temperature rise.Heat is a type of thermal energy.It is concerned with the first law of thermodynamics.

Thermal energy arises from friction and drag.It includes the internal energy or enthalpy of a body of matter and radiation.It is related to internal energy and heat .It arises when a substance whose molecules or atoms are vibrating faster.

These vibrating molecules and atoms collide and as a result of which heat is generated in a substance , more the collision of particles , higher is the thermal energy. There are 3 types of thermal energy 1) conduction 2)  convection 3) radiation

Explanation:

A student attaches a rope to the handle of a chest loaded with few books , books while the other end of the rope is tied to a scale. The student pulls the scale with just enough force to set the chest in motion and records the force applied on the spring scale. The student repeats the experiment with more books in the chest and records the data in a table.

Answers

Answer:

B. As the mass of the chest increases, more force is required to pull it.

Explanation:

Option B is the correct that can be concluded from the data.

From the data, we can see that the mass of the chest is on the increase; it increases from 50, 75, 100, 150 and to 175. Also, in the force column, we can see an increment in the force also; from 0.25, 0.50, 1.15, 1.50 and to 1.70. So, from this data, we discover that as the mass increases, the force needed to pull it increases also.  

Moreover, this is true even logically. If you want to pull an object with a heavy, more force will be required to pull it. Therefore, Option B is the correct answer.

Which of the following describes prophase of mitosis?
A. Chromosomes condense and nuclear membrane breates down.
B. Homologous chromosomes line up along the equator of the cell.
C. Cytoplasm divides as cell prepares to become two new cells.
D. Daughter chromosomes move toward opposite poles of the cell.

Answers

Answer:

Daughter chromosomes move toward opposite poles of the cell.

Explanation:

Prophase is the beginning of cell division. At this stage, the CHROMATIN from which the chromosomes are formed thickens and twists spirally and CHROMOSOMES are formed which become visible under a microscope.

CENTRIOLS are organelles whose main role is to form a dividing spindle during cell division, now they separate and move towards the poles of the cell.

When they reach the poles, the threads of the dividing spindle are formed between them. Chromosomes are attached to these threads.

A student observes that a plant has droopy leaves and stems and infers that the rate of photosynthesis has slowed in the plant. Which statement provides evidence to support the student’s inference?

Answers

Answer:

A. The water pressure in the plant's vacuole is low, and without water, the chloroplasts cannot convert carbon dioxide to glucose during photosynthesis.

Explanation:

Photosynthesis occurs on chloroplasts which are located on the surface of leaves. Photosynthesis is the conversion of carbon dioxide, water, and light energy to produce glucose and oxygen for plants.

The vacuoles inside the plant's cell contain stored food and absorb water through osmosis. Water in the vacuole has more solutes than water outside the vacuole. This causes the Turgor Pressure which the vacuole impacts on the plants. If the reverse becomes the case, water is lost from the vacuole causing it to shrink.

Flaccidity of the vacuole and the cell wall will cause the chloroplasts where photosynthesis occurs to shrink.
