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.

The latent heat of vaporization
Answer:
For liquid at room temperature and pressure, the value of specific heat capacity (Cp) is approximately 4.2 J/g°C.
Explanation: This implies that it takes 4.2 joules of energy to raise 1 gram of water by 1 degree Celsius. This value for Cp is actually quite large. This (1 cal/g.

Answer: Work and Power
Explanation:
The formula "Fxd = W" is the formula for work. It is the cross product of how much force given some distance.
The next part, Im not sure why they used a W. It is very confusing the way they wrote it. That 'W' would be the power. Power has units of joules per second.

According to Newton's second law, acceleration of an object depends on the mass of the object and:
a. The net weight of the object
b. The inertia of the object
c. the net force acting on the object
Answer:
C. The net force acting on the object
Explanation:
The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.

FM radio bands range from 88 MHZ through 108 MHz. The speed of light is 3 × 108 m/s.
What is the wavelength for the FM radio band at 96 MHz?
Answer in units of m.
(part 2 of 2)
What is the wavelength for the FM radio band
at 106 MHz? Answer in units of m
λ = 3.125 m
λ = 2.83 m
Further explanationGiven
Frequency of radio : 96 MHz and 106 MHz
Required
The wavelength
Solution
Wavelength : from the crest to the crest of the next wave or the trough to the trough
Frequency (f): number of waves in one second
v = λ x f
λ = v : f
Input the value :
f = 96 MHz = 96 x 10⁶ Hz
λ = v : f
λ = 3 x 10⁸ : 96 x 10⁶
λ = 3.125 m
f = 106 MHz = 106 x 10⁶ Hz
λ = v : f
λ = 3 x 10⁸ : 106 x 10⁶
λ = 2.83 m
When a 5 kg rock is dropped from a height of 6 m on Planet X, it loses 24 J of GPE. What is the acceleration due to gravity on Planet X?
Answer:
g = 1.25m/s²
Explanation:
Given the following data;
Mass = 5kg
Height = 6m
Gravitational potential energy = 24J
To find the acceleration due to gravity;
Potential energy can be defined as an energy possessed by an object or body due to its position.
Mathematically, potential energy is given by the formula;
[tex] P.E = mgh[/tex]
Where,
P.E represents potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per seconds square.
h represents the height measured in meters.
GPE = mgh
Substituting into the equation, we have;
24 = 5*6*g
24 = 30g
g = 30/24
g = 1.25m/s²
Therefore, the acceleration due to gravity on Planet X is 1.25m/s².
Answer:
g=0.8m/s^2
Explanation:
M=5kg
h=6m
GPE=24J
GPE=Mgh
g=GPE/Mh
g=24J/(5kg)(6m)=0.8
g=0.8m/s^2
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]

Plan meals ahead of time to ensure that you eat a healthy well-balanced meal.
Keep more fruits, low-fat dairy products (low-fat milk and low-fat yogurt), vegetables, and whole-grain foods at home and at work.

I know that some foods have a lot of sugar. I read online that I don’t need any more than 25 grams of added sugar a day. One kind of pop that I like to drink has 40 grams of sugar per can. I can start by drinking less pop. Next, I learned that some food makers are now putting nutrition keys on the front of their boxes. I love all kinds of breakfast cereal, so I can use the nutrition key to compare brands. Cereal high in fiber is good, but cereal high in sugar isn’t. I’ll be more careful, too, when ordering fast food. Sometimes fast-food places want to change the size of my order from medium to large for a higher price. From now on, I won’t pick the bigger meal. Picking the medium-sized meal should be better for me and can even save me money.

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.

simple machines are in a mousetrap
Answer:
A mousetrap makes use of a simple machine called a lever.
Explanation:
In a second-class lever the effort force is at the other end, with the load in the middle. In a third-class lever, the load is at the end and the effort force is between the fulcrum and the load. When you set the mousetrap, you are using a second-class lever. Sorry if I get this wrong. I am in 5th grade! ♥
What equation/formula would you use to find the distance an object traveled?
a.distance = s x t
b.distance = s/t
c.distance = t/s
Answer:
a. distance = s x t
Explanation:
The equation we know for speed is speed = distance/time, shortened to s = d/t
If you want to find the distance, you'd rearrange the formula to make d the subject. To isolate d, multiply by t on both sides (since it's being divided on the right. This leads to
s x t = d, with d isolated on the right side.
Therefore, to find the distance an object travelled you'd use a. distance = s x t

John slides down a hill at a 4 m height initially at rest. If all energy is conserved and friction is excluded, what is John's velocity at the bottom of the ramp?
The velocity at the bottom : v = 8.85 m/s
Further explanationGiven
height of the hill = 4 m
Required
The velocity at the bottom
Solution
The law of conservation energy :
ME₁=ME₂
(PE+KE)₁ = (PE+KE)₂
initially at rest⇒vo=0⇒KE₁=0
At the bottom⇒h=0⇒PE₂=0
So the equation becomes :
PE₁=KE₂

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.
