Using the model,what is the mass of the atom pictured?
A)3amu
B)5amu
C)7amu
D)9amu
Answer:
with 20 protons (p=20) and 22 neutrons (n=22)? 47 ... Listed below are the charges and masses of four ... a) +2,2 amu c ) +1, 1 amu least b) ... pudding” Model.
Explanation:
Answer:
7amu
Explanation:
Atoms are composed of three particles. The proton, neutron, and electron.
The mass of the atom in amu is just the number of protons and neutrons in the nucleolus since they both have a mass of about 1 amu. Electrons are not counted since they have an incredibly small mass that ultimately does not matter.
This atom has 3 protons (positively charged particle) and 4 neutrons (particle with no charge) which together gives a mass of 7 amu.

Las Vegas Raiders' running back Josh Jacobs is 72 inches tall and has mass of 100 kg. Los
Angeles Rams' defensive tackle Aaron Donald is also 72 inches tall but has a mass of 130
kg. Josh runs the ball East, towards the goal line, quickly traveling 50 yards in
5.5 seconds. Josh then accelerates towards the goal line at 9 m/s2. Aaron accelerates
West, the exact opposite direction, towards Josh at 6.5 m/s2. They both meet with an
explosive collision at the 1 yard line.
In a paragraph, address the following questions. Calculate numerical answers to the
nearest hundredth and correct units must be included.
1. What is Josh Jacobs' speed?
II. What is Josh Jacobs' velocity?
III. How much force does Josh Jacobs create?
IV. How much force does Aaron Donald create?
V. By calculating the net force, does Josh Jacobs score the touchdown.
Explain why or why not?
Answer:
Josh is running at a speed of 9.09 yards per second.
Josh's velocity is 9.09 East.
Josh's force is 900 N.
Aaron Donald's force is 845 N.
Yes Josh scores the touchdown because he is faster and has more mass than Donald.
Explanation:
Josh scores the touchdown as he is heavier and faster than Donald.
Formulas are:
Force= mass x acceleration
Speed= distance divided by time.
Velocity= distance divided by time.

Magnesium is a metal that is commonly used in products that need to be lightweight. Suppose a 2.00-kg piece of magnesium has 8160 J of energy added to it. Its temperature increases 4k. What is the specific heat of magnesium. Show your work
Answer:
The specific heat of magnesium is 1.02 J/g.K
Explanation:
To calculate the energy involved in the heating of the metal (magnesium), we use the following expression:
energy = mass x Cp x ΔT
We have the following data:
mass = 2.00 kg x 1000 g/1.00 kg = 2000 g
energy = 8160 J
ΔT = 4 K
Thus, we can calculate the specific heat of magnesium (Cp) in J/g.K as follows:
⇒ Cp = energy/(mass x ΔT) = 8160 J/(2000 g x 4K) = 1.02 J/g.K

Calculate the atoms of hydrogen in 52.0 g of H2O.
Answer:
34.81 ×10²³ atoms
Explanation:
Given data:
Mass of water = 52.0 g
Number of atoms of hydrogen = ?
Solution:
Number of moles of water:
Number of moles = mass/molar mass
Number of moles = 52.0 g/ 18 g/mol
Number of moles = 2.89 mol
1 mole of water contain 2 mole of hydrogen.
2.89 mole of water contain 2.89× 2= 5.78 moles of hydrogen.
Number of atoms of hydrogen:
1 mole = 6.022×10²³ atoms
5.78 mol × 6.022×10²³ atoms / 1mol
34.81 ×10²³ atoms

WHAT DOES THE MASS OF AN OBJECT MEASURE HURRYYYYYYYYYYYYYYYYYYYYY
Answer:
object's inertial property
Explanation:
The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.

Calculate the speed of a bicycle
traveling 20 km in 2 hours. Show the
formula, and your work with the correct
units. HELP PLEASE AND HURRY
Answer:
10 km/hr
............
The speed of a bicycle is 10 km/hour or 0.27 m/sec.
What is the Speed?The speed may be defined as the rate of change of position of an object in any direction. It is significantly measured as the ratio of distance to the time in which the distance was covered. Speed is a type of scalar quantity that has only direction but no magnitude.
According to the question, the distance traveled by bicycle = 20 km or 2000 meters.
The total time is taken = 2 hours or 7200 seconds.
Now, the formula for calculating the speed is as follows:
S = Distance/ Time = 20km/2 hours = 10 km/hour.
S = Distance/ Time = 2000 meters/7200 seconds = 0.277 m/sec.
Therefore, the speed of a bicycle is 10 km/hour or 0.27 m/sec.

Which of the following colors is/are produced when white light from sun is passed through a prism?
Answer:
Options d.
Explanation:
As white light from the sun is passed through a prism, it is separated into colors - red, violet, yellow, blue, green, orange, and indigo.
Dispersion is the process of the separation of visible light into its different component colors. The light waves are refracted as they enter the prism.
So, option d. is correct.
Will sodium displace iron from iron oxide?
Answer:
Explanation: A more reactive metal will displace a less reactive metal from a compound. The thermite reaction is a good example of this. It is used to produce white hot molten (liquid) iron in remote locations for welding. A lot of heat is needed to start the reaction, but then it releases an incredible amount of heat, enough to melt the iron.
aluminium + iron(III) oxide → iron + aluminium oxide
2Al + Fe2O3 → 2Fe + Al2O3
Because aluminium is more reactive than iron, it displaces iron from iron(III) oxide. The aluminium removes oxygen from the iron(III) oxide:
Answer:
Displacement reactions involve a metal and a compound of a different metal. In a displacement reaction:
Explanation:
a more reactive metal will displace a less reactive metal from its compounds
Displacement reactions are easily seen when a salt of the less reactive metal is in the solution. During the reaction:
the more reactive metal gradually disappears as it forms a solution
the less reactive metal coats the surface of the more reactive metal
For example, magnesium is more reactive than copper. When a piece of magnesium is dipped into blue copper sulfate solution:
the blue colour fades as colourless magnesium sulfate solution forms
brown copper coats the surface of the magnesium
