94

Explanation:

173 - 79 = 94

The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

Mass number given: 173

Gold Atomic number: 79

Neutrons: 94

Answer:

7500 m/s

Explanation:

We can use the equation velocity of a wave equals wavelength times  frequency.  Therefore, v = wavelength*f = (25 m)(300 Hz) =  m/s7,500

48 m/s in terms of km/h is 720.8 km/h. In terms of m/min is 2880 m/min, in terms of km/s is 0.048 km/s and in terms of km/min is 2.88 km/min.

To solve this question, we need to understand some terms. The unit of velocity is measured in m/s. It can be expressed in different units of velocity.

1 km (kilometer) = 1000 meter

1 h (hour) = 3600 seconds

1 minutes = 60 seconds

To convert m/s into km/h,

48 m/s * 3600/1000 =  172.8 km/h

To convert m/s into m/min,

48 m/s * 60 = 2880 m/min

To convert m/s into km/s,

48 m/s ÷ 1000 = 0.048 km/s

To convert m/s into km/minutes,

48 m/s * 60 / 1000 = 2.88 km/min

Therefore, the 48 m/s expressed is 172.8 km/h, 2880 m/min, 0.048 km/s and 2.88 km/min.

48 m/s is equivalent to  172.8 km/h, 2880 m/min, 0.048 km/s, and 2.88 km/minute.

To express 48 m/s in different units of velocity:

km/h (kilometers per hour):

To convert m/s to km/h, we can use the conversion factor of 3.6 since 1 m/s is equal to 3.6 km/h.

48 m/s * (3.6 km/h / 1 m/s) = 172.8 km/h

Therefore, 48 m/s is equivalent to 172.8 km/h.

m/min (meters per minute):

To convert m/s to m/min, we can use the conversion factor of 60 since there are 60 seconds in a minute.

48 m/s * (60 m/min / 1 s) = 2880 m/min

Therefore, 48 m/s is equivalent to 2880 m/min.

km/s (kilometers per second):

Since 1 kilometer is equal to 1000 meters, to convert m/s to km/s, we divide the value by 1000.

48 m/s / 1000 = 0.048 km/s

Therefore, 48 m/s is equivalent to 0.048 km/s.

km/minute (kilometers per minute):

To convert m/s to km/minute, we first need to convert m/s to km/s (as calculated in the previous step) and then multiply by 60 to convert seconds to minutes.

0.048 km/s * 60 = 2.88 km/minute

So, 48 m/s is equivalent to 2.88 km/minute.

Hence, 48 m/s is equivalent to approximately 172.8 km/h, 2880 m/min, 0.048 km/s, and 2.88 km/minute.

25.0 less force

Explanation:

Answer:

the si unit of force is newton

The new electrostatic force will be 384 units.  

The electrostatic force of attraction between two charges \(q_{1} \\\)(charge of object 1)  and \(q_{2}\)(charge of object 2) separated by a distance d is given by

\(F = \frac{q_{1} q_{2}}{4\pi E_{0} d^{2} } \\\)

\(E_{0} = 8.854 * 10^{-12} C^{2} N^{-1} m^{-1}\) is the permittivity of free space.

Initially, we have,

\(\frac{q_{1} q_{2}}{4\pi E_{0} d^{2} } =F_{1} = 8 units\)  

Now, if the charge of object 1 is multiplied by 1, the charge of object 2 is multiplied by 3, and the distance separating objects 1 and 2 is divided by 4, we have, \(q_{1} =q_{1}, q_{2} =3q_{2} , d=\frac{d}{4}\).

The new electrostatic force will be,

\(F_{2} = \frac{q_{1} 3q_{2}}{4\pi E_{0} (\frac{d}{4} )^{2} } \\\\\) units.

We have, \(F_{1} = 8 units= \frac{q_{1} q_{2}}{4\pi E_{0} d^{2} } \\\)

Hence,

\(F_{2} =\frac{8*3}{(\frac{1}{4}) ^{2} } units= 384 units.\)

Hence, the new electrostatic force will be 384 units.

A. Total momentum in a closed system is conserved

the law of momentum conservation states that The total amount of momentum before the collision is the same as the total momentum after the collision. Regardless of the change of momentum of each object.

Uniform line movement

Data:

V = 80km/h

T = 15m = 0.25 h

d = ?

We perform a conversion from minutes to hours.

           15 m * 1 h/60 m = 0.25 h

The formula for uniform motion is:

                      V = d/t

We clear for distance:

                  d = v * t

                  d = 80 km/h * 0.25 h

                  d = 20 km

The distance traveled in that time is 20 km.

The scientist who discovered that his theory predicted an expanding universe, and because he doubted the existence of expansion, modified his equations to eliminate the expansion from his theory was Albert Einstein.

The scientist who modified his equations to eliminate the expansion from his theory was Albert Einstein. In 1917, Einstein applied his theory of General Relativity to the entire universe and found that his equations predicted a dynamic, expanding universe. However, at the time, it was widely believed that the universe was static and unchanging, so Einstein introduced a mathematical term known as the cosmological constant to his equations to counteract the predicted expansion and maintain a static universe.

It was not until several years later, when observations by astronomer Edwin Hubble confirmed that the universe was indeed expanding, that Einstein realized his mistake and called the introduction of the cosmological constant his "biggest blunder." The idea of an expanding universe would eventually become an important cornerstone of modern cosmology.

According to the given statement Mrs. Brown's electricity bill for the current month is $5000.00.

To calculate Mrs. Brown's electricity bill for the current month, we need to determine the total number of kilowatt-hours (kWh) she has consumed and apply the corresponding rates.

1. Calculate the electricity usage:

  Current meter reading - Previous meter reading
  20,300 kWh - 17,800 kWh = 2,500 kWh

2. Determine the cost for the first 2000 kWh:

  $1.00/kWh * 2000 kWh = $2000.00

3. Determine the cost for the remaining kWh:

  500 kWh * $3.50/kWh = $1750.00

4. Add the fuel adjustment charge:

  $0.50/kWh * 2500 kWh = $1250.00

5. Calculate the total bill:

  $2000.00 + $1750.00 + $1250.00 = $5000.00


To calculate the electricity bill, we first find the difference between the current and previous meter readings.

In this case, Mrs. Brown used 2,500 kWh.

For the first 2000 kWh, the cost is $1.00 per kWh, resulting in a charge of $2000.00.

For the remaining 500 kWh, the cost is $3.50 per kWh, totaling $1750.00.

Additionally, a fuel adjustment charge of $0.50 per kWh is added to the bill. This amounts to $1250.00.

Finally, we add up all the charges to get the total bill, which is $5000.00.

Without air resistance, both the basketball and the medicine ball will fall at the same rate and reach the ground at the same time. This is due to the fact that gravity affects objects the same, regardless of their mass.

When a ball is dropped from a height, the only force acting upon it is gravity. Gravity pulls each ball with the same force; however, the ball with more mass will have more gravitational potential energy than the other. It means the basketball will have more potential energy to convert to kinetic energy during the fall, making it faster than the medicine ball.

Thus, in conclusion, the basketball would fall first as it is more massive than the medicine ball.
When a basketball and a medicine ball are dropped from the same height at the same time without air resistance, the basketball would land first. The explanation for this is due to the size and weight of each ball.

Basketball is heavier than the medicine ball, and both have the same height to fall. The more massive the object, the more gravitational pull it experiences, and thus, it falls faster. So, the basketball would land first if a basketball and a medicine ball are dropped from the same height at the same time without air resistance.

When deciding which compound has the highest boiling point, it is essential to consider intermolecular forces, molecular weight, and geometry.

Here are some points to keep in mind is Intermolecular forces. The strength of intermolecular forces influences the boiling point. The greater the intermolecular forces, the higher the boiling point of a compound. Molecular weight When two molecules have identical intermolecular forces, the one with the higher molecular weight will have a higher boiling point.

Geometry The shape of a molecule affects its boiling point. When two molecules have similar intermolecular forces and molecular weights, the molecule with the greater surface area will have a higher boiling point. For example, hydrogen chloride (HCl) has a higher boiling point than hydrogen sulfide (H2S). Despite being similar in molecular weight, HCl has a higher boiling point because it has stronger intermolecular forces.
