When nonmetals such as nitrogen and phosphorus are solids, they tend to be?
A
brittle
B
dense.
С
malleable
D
shiny
Answer:
answer is A hope this helps
Explanation:
According to the characteristics of non-metals such as nitrogen and phosphorous which are solids they are also brittle.
What are the characteristics of non-metals?Non-metals do not possess luster and are dull . They are not malleable and ductile and are soft due to the covalent bonding present in them . Non-metals on the other hand owing to their soft nature have low melting points.
Non-metals have four to seven valence electrons owing to which they usually form covalent bonds. They are poor conductors of heat and electricity and are mostly in liquid or gaseous state.They are widely used in the manufacture of fertilizers , in rocket fuels and in the form of graphite in pencil leads.
Non-metals have high ionization energies and high electronegativities.

What affects weathering rates
Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering. 2. Rocks in tropical regions exposed to abundant rainfall and hot temperatures weather much faster than similar rocks residing in cold, dry regions.
Suppose two equal mass cars traveling with equal speeds in opposite directions inelasticcollide head on and stick together. What fraction of the energy is dissipated
A collision which is inelastic is one in which the internal energy changes.
All the kinetic energy is dissipated
Reasons:
The given parameters are;
The mass of one car = The mass of the second car in the collision = m
The type of collision = Inelastic collision
The speed of each of the cars in the collision = v and -v
Solution:
In an inelastic collision, we have;
[tex]m_1 \cdot v_{1i} + m_2 \cdot v_{2i} = (m_1 + m_2) \cdot v_f[/tex]
Therefore, we get;
[tex]m \cdot v_{i} -m \cdot v_{i} = 0= 2 \cdot m \cdot v_f[/tex]
Which gives;
[tex]v_f = 0[/tex]
The collision is an example of a perfectly inelastic collision, and the final velocity after the collision is zero.
The change in the energy is [tex]\Delta K.E. = K.E._{final} - K.E._{initial}[/tex]
[tex]K.E._{initial}[/tex] = 0.5·m·v² + 0.5·m·v² = m·v²
ΔK.E. = 0.5·(2·m)×0 - 0.5·m·v² + 0.5·m·v² = -m·v²
ΔK.E. = -m·v²
The negative sign stands for energy given out, which gives;
The energy dissipated = m·v² (The total initial kinetic energy)
Therefore, all the kinetic energy is dissipated

Question 1
Analyze this: A rightward force of 80 N is applied to a 5.00 kg object to accelerate it to the right. The friction force
between the object and the surface is 30 N. Complete the diagram
The only part of the diagram that remains is the force that moves the object forward which is 50 N.
We know that the net force is obtained using the relation;
Net force = -Frictional force + Rightward force
The frictional force is negative because its direction is opposite to that of the forward force.
We have the following information from the question;
Frictional force = 30 N
Rightward force = 80 N
Mass = 5.00 kg
Net force is obtained from;
5a = 80 - 30
5a = 50
a = 10 m/s^2
Net force = 50 N, This the force that moves the object forward.

The method of measuring distance in space using parallax is equivalent to surveyors on Earth doing _______________. The smaller the parallax of an object, the greater its __________. When we measure parallax, the distance between the two observers (or two vantage points) is called the ___________. The first parallax to a star was not measured until 1838 because the stars are so _______________. The distance at which a star has a parallax of one second of arc is called a __________. In 1989, astronomers launched a satellite called __________ to measure parallax even better from outer space.
Answer:
Triangulation
Distance
Baseline
Far away
Parsec
Hipparcos
Astronomers are known to estimate the distance of nearby objects in space through the use of stellar parallax, or trigonometric parallax.
They often measure a star's movement using the background of more distant stars as Earth revolves around the sun.
With the use of Parallax, one can get the best way to have the distance in astronomy,
Triangulation is often used instead of parallax to know the terrestrial distances by forming triangles with a predefined base and measuring the angles formed with the other two sides.

Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
8 kg cat is running with a velocity of 4 m/s. What is the cat's momentum?
Answer:
Kinetic energy = (1/2) (mass) (speed)²
Kinetic energy = (1/2) (8 kg) (4 m/s)² =
(4 kg) (16 m²/s²) =
64 (kg-m/s²) (m) = 64 newton-m = 64 joules
A cat of mass 8 kg moving with a velocity of 4 m/s, then the momentum of the cat's movement will be equal to 32 kg m/s.
What is momentum?The momentum is the result of a particle's velocity and its mass. Force and motion, meaning it has both magnitude and the direction. According to Isaac Newton's second equation of motion, the force acting on a particle equals the time rate of increase of momentum.
The impulse, which is the product of the force and the intervals (the impulse), is equal to the difference in momentum, according to Newton's 2nd law, if a steady force operates on a particle for a specific amount of time. On the other hand, a particle's momentum is the amount of time needed for a consistent action to fight it to rest.
As per the data provided in the question,
Mass of the cat, m = 8 kg
Velocity of the cat, v = 4 m/s.
[tex]Momentum(p) = Mass(m)*velocity(v)[/tex]
p = (8 kg) × (4 m/s)
p = 32 kg m/s.
Therefore, the momentum of the cat is 32 kg m/s.

Energy transformation is demonstrated in the diagram is solar energy to heat energy.
What is energy?Energy is the ability or capability to do tasks, such as the ability to move an item (of a certain mass) by exerting force. Energy can exist in many different forms, including electrical, mechanical, chemical, thermal, or nuclear, and it can change its form.
Solar radiation is absorbed at the surface of a receiver, which includes oris in touch with flow passageways through which a working fluid moves, during thermal conversion operations. Heat is delivered from the heating receiver to the working fluid, which might be air, water, oil, or molten salt.

Kinetic energy is energy that possesses due to its motion. Basically, a moving object has kinetic energy.
Potential energy is the energy held by an object due to its position relative to other object. Which means it has the possibility (potential) to become kinetic energy, but at that moment where it’s not moving, it’s potential energy.
