Answer:
acceleration =
[tex]8.33ms {}^{ - 2} [/tex]
Explanation:
we know,
force = mass × acceleration
500 = 60 × aa = 500 / 60a = 50 / 6a = 8.33 m/s^28.33 m/s² quickly would a 60kg object accelerate if the person applied a 500N force.
Describe acceleration:Acceleration the rate at which speed and direction of a moving object vary over time. A point or object moving straight ahead is accelerated whenever it accelerates or decelerates. Even if the speed remains constant, motion on the a circle accelerates so because direction is constantly shifting.
Can an acceleration be negative?An item that is slowing down will always have a negative acceleration if the current direction of motion is constantly selected as positive.
Briefing:Force = mass × acceleration
500 = 60 × a
a = 500 / 60
a = 50 / 6
a = 8.33 m/s²

.What is the relationship between the solar radius and the brightness of stars?
Answer:
Its radius is thought to be around 1400 times than of our sun, and its luminosity 270,000 greater than our sun. Also, if a star has the same radius as the sun but a higher surface temperature, the hotter star exceeds the sun in luminosity
Explanation:
As the solar radius of the star increases, the brightness of the star also increases.
What is meant by luminosity ?Luminosity is defined as the measure of brightness of a celestial object or the relative quantity of light.
Here,
Solar radius is a unit of distance, which is used to determine the size of the stars relative to the sun.
The size of the star and the luminous intensity are directly proportional. As the size of the star increases, the luminosity of the star also increases. Therefore, larger stars shine more brighter than the smaller ones.
The brightness of a star is directly proportional to the square of its solar radius. Therefore, the luminosity increases with increase in solar radius.
Hence,
As the solar radius of the star increases, the brightness of the star also increases.

In a close system a gas with constant volume at 20C and pressure
1bar a heat is added to increase its temperature to 120C. Find the
new pressure
I
Answer:
6bar
Explanation:
According to pressure law;
P1/T1 = P2/T2
Given the following;
P1 = 1bar
T1 = 20oC
P2 = ?
T2 = 120oC
Substitute
1/20 = P2/120
20P2 = 120
P2 = 120/20
P2 = 6bar
Hence the new pressure will be 6bar
9. What is the magnitude of the velocity of a 25 kilogram mass that is moving with a
momentum of 100 kilogram-meters per second? [Neglect friction] Round your
answer to the nearest tenths place.
Answer:
4
Explanation:
The momentum of the object is 100 kgm/s, therefore the magnitude of the velocity of the object is 4 meters per second.
What is Momentum?Momentum of an object is the product of its mass and velocity. Momentum is the quantity of motion which is made up of the amount of matter which is being moved and the velocity at which the object moves. When we walk, run, etc., then we have momentum.
p = m × v
where, p is the momentum of the object,
m is the mass of the object,
v is the velocity of the object
p = 100 kgm/s
m = 25 kg
p = m × v
v = p/m
v = 100/ 25
v = 4 m/s
Therefore, the magnitude of velocity of the object is 4 meters per second.

Answer:
To calculate the voltage, current, power and energy for an inductor and also to examine the behavior of an inductor under dc conditions.
an inductor is a passive circuit element that stores energy in its magnetic field.
Explanation:
An inductor has been described as a passive electronic component that stores electrical energy in a magnetic form. It uses a conductor that is wound into a coil to produce DC current, acting as a short circuit when direct current is applied. When electricity flows into the coil from the left to the right, a current is generated through a magnetic field in the clockwise direction. It is also called a choke because of its frequency regulation.
A cube of wood with a side length of 1 meter is place in the water. It half of the wood sank under the water, find the mass of the wood. (density of water 1.0 × 103kg/m3)

What happens to ar object in free fall?
Suppose you have a cylinder filled with diatomic oxygen (O2) and it is running low. The cylinder is shown above, is made of steel, and has a fixed volume of 10 L.
You are asked to determine the number of O2 molecules that are left in the cylinder, so you take a measurement of the temperature to be 20℃. You then note that the pressure gauge reads 100 psi, which you checked at sea level in Bellingham, where the local pressure is one atm (14.7 psi). Calculate the number of O2 molecules left in the container.
Answer:
The number of O₂ molecules that are left in the cylinder is 1.70x10²⁴.
Explanation:
The number of oxygen molecules can be found using the Ideal Gas law:
[tex] PV = nRT [/tex]
Where:
P: is the pressure = 100 psi
V: is the volume = 10 L
n: is the number of moles =?
T: is the temperature = 20 °C = 293 K
R: is the gas constant = 0.082 L*atm/(K*mol)
Hence, the number of moles is:
[tex]n = \frac{PV}{RT} = \frac{100 psi*\frac{1 atm}{14.7 psi}*10 L}{0.082 L*atm/(K*mol)*293 K} = 2.83 moles[/tex]
Now, the number of molecules can be found with Avogadro's number:
[tex]n_{m} = \frac{6.022 \cdot 10^{23}\: molecules}{1\: mol}*2.83 moles = 1.70 \cdot 10^{24} \: molecules[/tex]
Therefore, the number of O₂ molecules that are left in the cylinder is 1.70x10²⁴.

A spacecraft drifts through space at a constant velocity. Suddenly, a gas leak in the side of the spacecraft gives it a constant acceleration in a direction perpendicular to the initial velocity. The orientation of the spacecraft does not change, so the acceleration remains perpendicular to the original direction of the velocity. What is the shape of the path followed by the spacecraft in this situation
Answer: The path will be a parabola.
Explanation: The path is a parabola because the motion described is a projectile motion, in which an object thrown or projected is subjected only to the acceleration.
In this motion, velocity must be constant and horizontal and acceleration is perpendicular compared to the direction of the velocity. In these conditions, the path is a parabola and the motion is a projectile.

When one person shouts at a football game, the sound intensity level at the center of the field is 69.6 dB. When all the people shout together, the intensity level increases to 103 dB. Assuming that each person generates the same sound intensity at the center of the field, how many people are at the game
Answer:
there are 2188 people at the game
Explanation:
Given the data in the question;
we know that decibel is defined as; dB = 10log(l/l₀)
so if one produces an intensity l₁, it results in 69.6 dB
69.6 = 10log(l₁/l₀) ---- equ1
also. if x number of people produces this intensity, it result to 103 dB
103 = 10log(xl₁/l₀)
103 = 10( log(l₁/l₀) + log(x) )
103 = 10log(l₁/l₀) + 10log(x) ----- equ2
input equation 1 into to equation 2
103 = 69.6 + 10log(x)
10log(x) = 103 - 69.6
10log(x) = 33.4
divide both side by 10
log(x) = 3.34
x = [tex]10^{3.34}[/tex]
x = 2187.76 ≈ 2188
Therefore, there are 2188 people at the game

An unfortunate astronaut loses his grip during a spacewalk and finds himself floating away from the space station, carrying only a rope and a bag of tools. First he tries to throw a rope to his fellow astronaut, but the rope is too short. In a last ditch effort, the astronaut throws his bag of tools in the direction of his motion, away from the space station. The astronaut has a mass of ma=102 kgma=102 kg and the bag of tools has a mass of mb=10.0 kg.mb=10.0 kg. If the astronaut is moving away from the space station at vi=2.10 m/svi=2.10 m/s initially, what is the minimum final speed vb,fvb,f of the bag of tools with respect to the space station that will keep the astronaut from drifting away forever?
Answer:
The answer is "[tex]2.352 \ \frac{m}{s}[/tex]"
Explanation:
[tex]\to mass(m_1)=102 \ kg\\\\\to mass(m_2)=10 \ kg \\\\\to v=2.10\ \frac{m}{s}\\\\[/tex]
momentum before:
[tex]\to p=(m_1+m_2)v[/tex]
[tex]=(102+10)2.10\\\\=(102\times 2.10 +10 \times 2.10)\\\\=214.2+21\\\\=235.2[/tex]
momentum After:
[tex]\to p=(m_1+m_2)v[/tex]
[tex]=(102\times 0 +10 \times v)\\\\ =(0 +10v)\\\\=10v\\[/tex]
Calculating the conservation of momentum:
[tex]\to \text{momentum before = momentum After}[/tex]
[tex]\to 235.2=10v\\\\\to v= \frac{235.2}{10}\\\\ \to v=2.352 \ \frac{m}{s}[/tex]

The mass and weight of box is 25 Kg and 245 N respectively when on Earth. What is the value of mass and weight of the box when it is brought to the moon?
Answer:
25 (kg) and 40.5 (N).
Explanation:
1) the value of 'g' on the Earth is ~9.81 (N/kg), the value of 'g' on the Moon is ~1.62 (N/kg).
It means, the mass is not depended on the value of 'g', but the weight is depended on it.
2) the mass on the Moon is the same, 25 kg.
the weight is 25*1.62=40.5 N
