7.According to the periodic table, how many total particles are there in the nucleus of a Titanium, Ti, atom?
Answer:
there are 22 massive, positively charged, fundamental particles in the element's nucleus. Given this, the element is unquestionably titanium.
The nucleus of titanium contains 46 particles in total in which 22 protons and 26 neutrons.
What is atomic nucleus?The atomic nucleus can be described as the small and dense region containing of protons and neutrons at the center of an atom. An atom is made of a positively charged nucleus, with electrons surrounding it, bound together by electrostatic force.
Almost all of the mass of an atom is concentrated in the nucleus as the mass of electrons is negligible. Neutrons and Protons are bound together to create a nucleus by the nuclear force.
The diameter of the nucleus is about 1.70 fm for hydrogen to about 11.7 fm for uranium. Protons and neutrons are fermions, are the particles present inside the nucleus.
The titanium has 22 protons and 26 neutrons in its nucleus so it has 46 particles in its atomic nucleus.

what is the average acceleration of a car that is initially at rest at a stop light and then accelerates to 24 m/s in 9.4 s?
Answer:
Below
Explanation:
To find the acceleration of the car you can use this formula :
vf = vi + at OR a = v/t
I'm going to use the first one because it explains the steps more clearly :
vf = 24 m/s
vi = 0 m/s
t = 9.4 s
a = ?
24m/s = 0 + (a)(9.4s)
24m/s = a9.4
Divide both sides by 9.4
a = 2.55319 m/s^2
Round to 3 sig figs
a = 2.6 m/s^2
Hope this helps! Best of luck <3

the object. If this object is 10 kg,
how/where will it accelerate?
Answer:
the free-body diagram shows the vectors for all the forces acting on the body. The resultant vector found by summing all the individual vectors represents the net force. Since F = ma, the acceleration vector will point in the same direction as the net force, with a magnitude of F / m

Which line on the graph represents the greatest positive acceleration?
D
A
B
C
Answer:
I think it's B, if that's wrong I apologize. You might want to do more research on it and find the correct answer if you can, if it's right then you could like my comment, so others know if not give it 1 star, keep it low lol.
Explanation:
The line that represents the greatest positive acceleration is A.
In a velocity-time graph, the slope of the line represents the acceleration. The greater the slope, the greater the acceleration. Line A has the steepest slope, so it represents the greatest positive acceleration.
Line B has a positive slope, but it is not as steep as line A. Line C has a negative slope, which means it represents negative acceleration, or deceleration. Line D is a horizontal line, which means it represents a constant velocity, or zero acceleration.
Therefore, the line that represents the greatest positive acceleration is A.

A box is in contact with a floor with a coefficient of friction of 0.50. If the box has a normal force of 500N, what force do have to push with to move the box? HELPPP
Answer:
250N
Explanation:
Coefficient of friction=frictional force/Normal force
coefficient of friction= 0.5Normal force(R)= 500NFrictional force (Fr)= ?0.5= Fr/500N
Fr= 500N×0.5 = 250N
Fr= 250N

1. Gold (Au): Gold has been used by humans for thousands of years, with evidence of its use dating back to ancient civilizations like the Egyptians, Sumerians, and Indus Valley people.
2. Silver (Ag): Like gold, silver has a long history of human use and has been mined and utilized for various purposes since ancient times.
3. Copper (Cu): Copper is one of the oldest metals known to humans, and its use dates back over 10,000 years. It was one of the first metals to be smelted and used in tools, weapons, and art.
4. Iron (Fe): Iron is another ancient element that has been used for thousands of years. Early civilizations discovered iron in meteorites and later learned to smelt it from iron ores.
5. Lead (Pb): Lead has been known to humans since ancient times and was used by the ancient Egyptians, Greeks, and Romans. It was widely used in plumbing, as well as for making containers and pigments.
6. Tin (Sn): Tin has been used by humans for thousands of years, mainly in the form of an alloy called bronze (copper-tin alloy), which was crucial for the Bronze Age.
7. Mercury (Hg): Mercury has a long history of use in various cultures for medicinal, alchemical, and decorative purposes.
8. Sulphur (S): Sulfur has been used since ancient times for various purposes, including medicine, bleaching, and as a component in sulfuric acid production.
9. Carbon (C): While the element carbon itself has always existed on Earth, the awareness of its presence and significance as an element is ancient.
These elements were used by ancient civilizations for various purposes such as jewelry, tools, construction, and religious rituals. Their discovery dates are lost in antiquity, as they have been known to humans for thousands of years.

A straight line with a positive slope on a velocity-time graph indicates which of the following?
no mo
Answer:
constant acceleration
Explanation:
I may be wrong, but I'm almost positive cuz I am also taking physics. ;)
Answer:
Constant acceleration in the positive direction.
Explanation:
Because it is a straight line with a positive slope, we can infer that the rate of acceleration remains constant as the line is linear, and as it states in the question, the slope is positive; therefore, it is moving in a positive direction.
