Answer:
[tex]A=0.136\ m^2[/tex]
Explanation:
The air pressure inside a car tire is 3 atm = 303975 Pa
The force of 41,500 N of force pushing out on the tire.
We need to find the surface area of the inside of the tire. The pressure acting on an object is given by :
[tex]P=\dfrac{F}{A}\\\\A=\dfrac{F}{P}\\\\A=\dfrac{41500}{303975}\\\\A=0.136\ m^2[/tex]
So, the surface area of the inside of the tire is [tex]0.136\ m^2[/tex].

If a 25kg car accelerates at a speed 100m/ s2 s2, what will the force of the car be?
Plug in the numbers: Force=mass x acceleration
Answer:
2500 Newtons
Explanation:
If force equals the mass × acceleration then all should be quite simple
25kg is the mass of your car
100 m/s/s is the acceleration of you car
25kg • 100m/s/s = 2500 Newtons
Answer:
[tex]\boxed {\boxed {\sf 2500 \ Newtons }}[/tex]
Explanation:
The formula for force is the product of mass and acceleration.
[tex]F=m*a[/tex]
The mass of the car is 25 kilograms and the acceleration is 100 meters per square second. So,
[tex]m= 25 \ kg \\a= 100 \ m/s^2[/tex]
Substitute the values into the formula.
[tex]F= 25 \ kg * 100 \ m/s^2[/tex]
Multiply.
[tex]F= 2500 \ kg*m/s^2[/tex]
1 kilogram meter per square second is equal to 1 NewtonOur answer of 2500 kg*m/s² is equal to 2500 Newtons[tex]F= 2500 \ N[/tex]
The force of the car is 2500 Newtons.

28.5 g of iron shot is added to a graduated cylinder containing 45.50 mL of water. The water level rises to the 49.10 mL mark. From this information, calculate the density of iron.
Answer:
Density=mass/volume.
1) we have to calculate the iron volume in liters.
iron volume=second level - first level=49.10 ml-45.50 ml=3.6 ml
3.6 ml=3.6 ml(1 liter / 1000 ml)=0.0036 liters
2) we calculate the mass iron in kg.
28.5 g=28.5 g(1 kg /1000 g)=0.0285 kg.
2) we calculate the density of iron.
density=0.0285 kg / 0.0036 liters=7.92 kg/L
7.92 kg/l=7.92 kg/L(1000 g/1Kg)(1000 cm³/1 L)=7.92 g/cm³.
From this information the Iron density is 7.92 Kg/L or 7.92 g/cm³.
Explanation:
I hope this helps u! :D
Answer:
7.92 g/cm^3
Explanation:
1 mL = 1 cm^3
density = mass/volume
volume: 49.10 mL - 45.50 mL = 3.60 mL = 3.60 cm^3
mass: 28.5 g
density = (28.5 g)/(3.60 cm^3) = 7.91666... g/cm^3
Answer: 7.92 g/cm^3

A cart at rest accelerates to a speed of 30 meters per second over a 3.0 second time interval. What is the average velocity of the cart during these 3.0 seconds? P.4B
Answer:
15 m/s
Explanation:
Given data
Initial velocity= 0m/s----------since the cart was at rest
Final velocity = 30m/s
time= 30 seconds
Required
the average speed
We know that the sum of the initial and final velocity is divided by 2 to find the average velocity
average velocity= 0+30/2
average velocity= 30/2
average velocity= 15 m/s
Hence the average velocity is 15 m/s

A boy kicks a football with a force of 420.0 N for a time of 22.3 s. What is the impulse and change in momentum?
Answer:
the impulse and change in momentum of the football is 18.83 N/s.
Explanation:
Given;
applied force, F = 420 N
time of force action, t = 22.3 s
The impulse and change in momentum of the football is calculated as;
J = ΔP = [tex]\frac{F}{t}[/tex]
where;
J is the impulse
ΔP is the change in momentum
J = ΔP = [tex]\frac{F}{t}= \frac{420}{22.3} = 18.83 \ N/s[/tex]
Therefore, the impulse and change in momentum of the football is 18.83 N/s.
What is the final temperature of 5kg of water, with an initial temperature of 5oC, after 50kJ of energy has been transferred to it. The specific heat capacity of water is 4200 J/kgoC
Answer:
[tex]T_f=7.38^{\circ}[/tex]
Explanation:
Given that,
Mass, m = 5 kg
Initial temperature of water, [tex]T_i=5^{\circ} C[/tex]
Heat transferred, Q = 50 kJ = 50,000 J
The specific heat capacity of water is 4200 J/kg°C
We need to find the final temperature of the water. The heat transferred in the process is given by :
[tex]Q=mc\Delta T\\\\Q=mc(T_f-T_i)\\\\\dfrac{Q}{mc}+T_i=T_f\\\\T_f=\dfrac{50000}{5\times 4200}+5\\\\T_f=7.38^{\circ}[/tex]
So, the final temperature of water is [tex]7.38^{\circ}[/tex].
Which process causes the transfer of energy by air currents within the Earth's atmosphere?
Answer:
Conduction, radiation and convection all play a role in moving heat between Earth's surface and the atmosphere. Since air is a poor conductor, most energy transfer by conduction occurs right near Earth's surface
A trash compactor pushes down with a force of 500 N on a 3 cm2 input piston, causing a force of 30,000 N to crush the trash. What is the area of the output piston that crushes the trash
Answer:
[tex]180 cm^2[/tex]
Explanation:
We are given that
Force [tex]F_1=500 N[/tex]
[tex]A_1=3cm^2[/tex]
[tex]F_2=30000 N[/tex]
We have to find the area of the output piston that crushes the trash
Input piston=Output piston
We know that
[tex]Pressure=\frac{force}{Area}[/tex]
Using the formula
[tex]\frac{F_1}{A_1}=\frac{F_2}{A_2}[/tex]
Substitute the values
[tex]\frac{500}{3}=\frac{30000}{A_2}[/tex]
[tex]A_2=\frac{30000\times 3}{500}[/tex]
[tex]A_2=180 cm^2[/tex]
Hence, the area of the output piston that crushes the trash 180 square cm
A trash compactor pushes down with a force of 500 N on a 3 cm² input piston, causing a force of 30,000 N on a 180 cm² output piston.
In physics, the pressure (P) is the force (F) applied perpendicular to the surface of an object per unit area (A) over which that force is distributed.
[tex]P = \frac{F}{A}[/tex]
A trash compactor pushes down with a force of 500 N (F₁) on a 3 cm² (A₁) input piston, causing a force of 30,000 N (F₂) to crush the trash.
Since the pressure in both pistons is equal, we can use the previous expression to calculate the area of the output piston (A₂).
[tex]\frac{F_1}{A_1} = \frac{F_2}{A_2} \\\\A_2 = \frac{A_1 \times F_2}{F_1} = \frac{3cm^{2} \times 30,000N}{500N} = 180cm^{2}[/tex]
A trash compactor pushes down with a force of 500 N on a 3 cm² input piston, causing a force of 30,000 N on a 180 cm² output piston.

What is the net force of a scooter acting on the road with an impulse of 550 Ns for 10s.
Answer:
55N
Explanation:
Impulse is the product of Force and Time
Impulse = Force * Time
Given
Impulse = 550Ns
Time = 10s
Force = Impulse/Time
Force = 550/10
Force = 55N
Hence the net force on the scooter is 55N

A negative charge of 0.198 C exerts an attractive force of 83,506 N on a second charge that is 3,004 m away. What is the magnitude of the second charge? ( solve for one of the charges)
Answer:
-606.73C
Explanation:
According to coulombs law
F = kq1q2/r^2
Substitute the given value
83,506 = 9*10^9(-0.198)q2/(3004)^2
83,506 = -1.242*10^9q2/9,024,016
-1.242*10^9q2 = 7.54*10^11
q2 = -7.54*10^11/1.242*10^9
q2 = -606.73C
hence the magnitude of the other charge is -606.73C
A refrigerator having a power rating of 350W operates for 12 hours a day. calculate the cost of electrical energy to operate it for 30 days. the rate of electrical energy is rs4.50 per kWh. calculate the minimum fuse rating to be put in the refrigerator circuit if the supply voltage is 240V.
Answer:
See the answers below.
Explanation:
The cost of energy can be calculated by multiplying each given value, a dimensional analysis must be taken into account in order to calculate the total value of the cost in Rs.
[tex]Cost=0.350[kW]*12[\frac{hr}{1day}]*30[days]*4.5[\frac{Rs}{kW*hr} ]=567[Rs][/tex]
The fuse can be calculated by knowing the amperage.
[tex]P=V*I[/tex]
where:
P = power = 350 [W]
V = voltage = 240 [V]
I = amperage [amp]
Now clearing I from the equation above:
[tex]I=P/V\\I=350/240\\I=1.458[amp][/tex]
The fuse should be larger than the current of the circuit, i.e. about 2 [amp]

KIIS FM broadcasts at 102.7 MHz, what is the wavelength of that radio wave?
Answer:
2.92 m
Explanation:
As we know, frequency × Wavelength = Speed of light
so here frequency of 102.7 MHz can be written as 102.7× 10⁶ Hz..
So Lambda (wavelength) = 3×10⁸/ 102.7 × 10⁶ which gives 2.92 metres or 2.92 × 10¹⁰ Å
