Nitrogen-14 has 7 protons. How many neutrons does it have?
Answer:
7
Explanation:
Using information found on the Periodic Table of Elements:
Nitrogen contains 7 protons, 7 neutrons, and 7 electrons.
..
Atomic number is 7
Atomic mass is 14
The mass number is the sum of protons and neutrons in the nucleus.
=> You can subtract the atomic number from the mass number to find the number of neutrons.

How does visible light interact with objects to produce the colors we see?
Answer:
Visible light when all put together is white. When objects appear to be, lets say, red, it would be the only color not absorbed by that object. same goes with all other colors. So black objects absorb all colors (not 100%) and that is why black clothing gets hotter, it simply absorbs all incoming light, as apposed to white that will reflect the colors back, making all of them together appear white. Hope this helps, not the best at explaining things.
Which of the following is a conversion from light energy to chemical energy?
a. turning on a stove to heat dinner
b. growing an apple tree
c. turning on a lamp
d. Turning on a blender
Answer:
A
Explanation:
turning on a stove to heat dinner because it undergoes a chemical reaction to transform into other substance
Growing up a tree is a conversion from light energy to chemical energy.
What is law of energy conservation?Energy can neither be created nor be destroyed , it gets only transferred from one form to another.
What is photosynthesis?The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.In simple words by the process of photosynthesis a tree makes food for itself.What happens when a tree grows?Tree makes food by absorbing the sunlight.The energy of the sunlight is used in making of ATPs in trees.ATP ( Adenosine triphosphate ) is used in various operations in trees.So, the sunlight is light energy which get converted into ATPs , which is chemical energy.
Thus, Growing up a tree is a conversion from light energy to chemical energy.

Un semáforo de 80N cuelga del punto medio de un cable de 30m tendido entre 2 postes. Halle la tensión en cada segmento del cable si éste tiene un pandeo que lo hace descender una distancia vertical de 1m
Answer:
T1 = T2 = 602.33 N
Explanation:
I attached an image of the forces diagram below.
The x component of the forces for this cases is:
[tex]\Sigma F_x=T_1cos\theta-T_2cos\theta=0\\\\T_1cos\theta=T_2cos\theta\\\\T_1=T_2[/tex]
And the y components:
[tex]\Sigma F_y=T_1sin\theta+T_2sin\theta-W=0\\\\T_1=T_2=T\\\\\Sigma F_y=2Tsin\theta=W\\\\T=\frac{W}{2sin\theta}[/tex]
The angle is calculated by using the information about the length of the cable and the vertical distance of the traffic light:
[tex]\theta=tan^{-1}(\frac{1}{15})=3.81\°[/tex]
Thus, you obtain:
[tex]T=\frac{80N}{2(sin3.81\°)}=601.33N[/tex]
hence, the tension in both segments of the cable is 602.33 N
Which has greater kinetic energy: a bullet that has a mass of 0.05 kg travelling at 2500 m/s, or a lorry that has a mass of 4500 kg and is moving at 50 m/s?
Answer:
its the lorry
Explanation:
The kinetic energy of the truck will be, 5625000 kg m/s and the kinetic energy of the bullet will be 156250 kg m/s. So the kinetic energy of the lorry will be higher than the kinetic energy of the Bullet.
What is Kinetic Energy?Kinetic energy is a type of energy that a particle or an object possesses as a result of its motion. By exerting a net force on an item, work is done, which transfers energy; as a result, the object accelerates and obtains kinetic energy.
A moving item or particle's ability to move depends on both its mass and velocity. This is known as kinetic energy. Translation (or movement along a path from one location to another), rotation about an axis, vibration, or any combination of motions are examples of possible types of motion.
According to the question,
K.E of the lorry: 1/2 (4500)(50)²
K.E of the lorry = 5625000 kg m/s.
K.E of the bullet: 1/2(0.05)(250)²
K.E of the bullet = 156250 kg m/s
Hence, the kinetic energy of the lorry is greater than the kinetic energy of the bullet.

What is the density of the object that has a mass 13.87g and a volume of 31.75cm3?
Answer:
d=0.4368 g/cm³
Explanation:
Density of an object is defined as the ratio of its total mass to the mass volume.
So that it is
d= m/V
d= (13.87g) / (31.75cm³)
d= 0.4368g/cm³

A paint brush is dropped from the top of a tall ladder and free falls to the ground. What changes, if any, would be observed of the velocity and the acceleration of the brush as it falls? Pick the two answers. The velocity increases. The velocity decreases. The velocity remains a constant value. The acceleration increases. The acceleration decreases. The acceleration remains a constant value.
Answer:
Explanation:
As the paint brush is dropped from the top of a tall ladder it started free falling
i.e. velocity of brush increases as it falls down due to the acceleration provided by gravity.
We know acceleration due to gravity is the attraction experienced by the object due to earth attraction
Value of acceleration due to gravity is constant i.e. [tex]9.8\ m/s^2[/tex]
Therefore the correct choice is
velocity is increasing and acceleration is constant

Se tienen 2 vectores cuyos módulos están en la misma razón que 5 y 2. Si cuando forman 53º su resultante mide 3√29u, ¿Cuánto mide el mayor vector?
Answer:
|v2| = 3.27
Explanation:
You have two vector v1 and v2. The relation between the magnitudes of both vectors is given by:
[tex]\frac{|v_1|}{|v_2|}=\frac{5}{2}[/tex]
Furthermore, the projection (the dot product) of one vector on the other one is given by the following formula:
[tex]v_1 \cdot v_2 = |v_1||v_2|cos\theta[/tex]
The dot product between v1 and v2 is 3√29. If you multiply the right hand side of the last equation by |v2|/|v2| you obtain:
[tex]3\sqrt{29}=\frac{|v_1|}{|v_2|}|v_2|^2cos(53\°)[/tex]
you do |v2| the subject of the formula:
[tex]|v_2|=\sqrt{\frac{|v_2|}{|v_1|}\frac{3\sqrt{29}}{cos53\°}}\\\\|v_2|=\sqrt{\frac{2}{5}\frac{3\sqrt{29}}{cos53\°}}=3.27[/tex]

Refer to the model below. A science student is camping with her family for one month at Stone Mountain Park. In a journal she records a model of the moon phases she observes. If she began recording the moon phases at position X, which sequence of Moon phase models could be seen by her during the 4-week period?
Answer:
New Moon - Crescent Moom ---- Full Moon ---- Waning Quarter
Explanation:
The Moon revolves around the Earth in a 28 day period, which is approximately one Earth month, therefore S the student has been recording the movement of the Moon for 4 Earth weeks this is a period of complete revolution of the Moon .
Consequently you must register the following phases
New Moon - Crescent Moom ---- Full Moon ---- Waning Quarter
in the period where it begins, it must go through the cycle in an orderly way to the right.
