A 1500 kg car is being lifted by a hydraulic jack attached to a flat plate. Underneath the plate is a pipe with radius of 24 cm at the top and 2cm at the bottom. To generate an upward acceleration for the car of 1.0 m/s2, how much force must be applied to the small end of the pipe? The answer is NOT 102 N btw
Answer:
The force that must be exerted at the other end is 102.08 N/m₂
Explanation:
Using Pascal's formula; P₁ = P₂
P₁ = F₁/A₁ = m*g/(πr²)
m = 1500 kg; g = 9.8 m/s², r = 24 cm = 0.24 m
P₁ = (1500 * 9.8)/(22/7 * 0.24 * 0.24)
P₁ = 81235 N/m²
P₂ = F₂/A₂
A₂ = πr² where π = 22/7; r = 2.00 cm = 0.02m
A₂ = 22/7 * 0.02 * 0.02 = 0.00126 m²
P₂ = F₂ / 0.00126 m₂
substituting in the formula P₁ = P₂
81235 N/m² = F₂ / 0.00126 m²
F₂ = 81235 N/m² * 0.00126 m²
F₂ = 102.08 N/m₂

A uniform, horizontal 300 N beam, 5.00 m long, is attached to a wall by a pin connection that allows the beam to rotate. Its far end is supported by a cable that makes an angle of 53.0° with the horizontal. If a 600 N person stands 1.50 m from the wall, find the tension in the cable and the force exerted on the beam by the wall
Answer:Given A uniform horizontal beam with a length of 8.00 m and a weight of 200 n is attached to a wall by a pin connection ( allows rotation). Its far end is supported by a cable that makes an angle of 53 degrees with the horizontal. If a 600 n person stands on the beam at 2.00 m from the wall , find the tension in the cable
Now the force acting on the beam are the gravitational force of earth and weight attached to a wall is 200 N which acts at centre. Also force of person standing is 600 N and force exerted is r and tension is T , also torque due to r is zero because it acts at the pivot point. So r = 0
Torque due to tension in the rope is sin 53 x 8.00 x T.
Torque due to force is 2.0 m x 600 N
The weight of beam acts in the centre since the beam is uniform.
So we have
sin 53 x 8.00 x T - 2 m x 600 N - 4 x 200 N = 0
8 .00 x 0.8 x T = 1200 + 800
0.64 T = 2000 N-m
T = 2000 / 0.64
T = 312.5 N
Explanation:
The tension in the cable and the force exerted on the beam by the wall will be 312.5 N and 1200N respectively.
What is force?Force is defined as the push or pull applied to the body. Sometimes it is used to change the shape, size, and direction of the body. Force is defined as the product of mass and acceleration. Its unit is Newton.
The given data in the problem is;
L is the length 5.00 m long,
[tex]\rm \theta[/tex] is the angle of 53.0°
d is the distance = 1.50 m
T is the tension in the cable
F is the force exerted on the beam by the wall= ?
Torque due to tension in the rope is
[tex]\rm \tau = 8.00 \times sin 53^0 \times T[/tex]
Force due to the torque will be;
F= 2.0 m x 600 N
F= 1200 N
The net tension is found as on applying the static equilibirium equation;
sin 53 x 8.00 x T - 2 m x 600 N - 4 x 200 N = 0
8 .00 x 0.8 x T = 1200 + 800
0.64 T = 2000 N-m
T = 2000 / 0.64
T = 312.5 N
Hence the tension in the cable and the force exerted on the beam by the wall will be 312.5 N and 1200N .

a small table has a mass of 4kg, stands on four legs, each leg having an area of 0.001 m2. what is the pressure exerted by the table on the floor?
Answer:
P = 10 kPa
Explanation:
Given that,
The mass of a small table, m = 4 kg
The area of each leg = 0.001 m²
We need to find the pressure exerted by the table on the floor. Pressure is equal to the force per unit area. So
[tex]P=\dfrac{mg}{4\times A}\\\\P=\dfrac{4\times 10}{4\times 0.001}\\P=10000\ Pa\\\\or\\\\P=10\ kPa[/tex]
So, the required pressure is 10 kPa.

If energy is conserved, then:
O A. initial (PE + KE) = final (PE + KE).
O B. the initial KE must be zero.
O C. the momentum does not change.
O D. PE(before) = KE(before).
If energy is conserved, then initial (PE + KE) = final (PE + KE). So, the correct option is A.
What is meant by Law of Conservation of Energy ?The law of conservation of energy states that, energy can neither be created nor be destroyed, but can be transformed from one form to another.
Here,
According to law of conservation of energy,
The total energy of an isolated system remains constant. That means, the total energy of the system in the initial state will be same as that in the final state.
The total mechanical energy is the sum of kinetic energy and potential energy.
TE = KE + PE
Therefore, the energy to be conserved in the system,
Initial TE = Final TE
So, Initial (KE + PE) = Final (KE + PE)
Hence,
If energy is conserved, then initial (PE + KE) = final (PE + KE).

If two alpha particles (each with two protons and two neutrons) are 0.500 m apart, what is the electric potential energy of the system?
Answer:
U = 1.84 10⁻²⁷ J
Explanation:
Electric potential energy is
U = k q₁q₂/ r
in this case the electric charge is
q = 2 p
q = 2 1.6 10⁻¹⁹
q = 3.2 10⁻¹⁹ C
indicate the distance between the charges is 0.500 m
we calculate
U = 9 10⁹ 3.2 10⁻¹⁹ 3.2 10⁻¹⁹ /0.500
U = 1.84 10⁻²⁷ J
A lever of class 1 has a lotal length of 3m and is
able to lift a load of 60N with a force of 30N at a Time Find
the position of the fulcrum.
Answer:
Fin Lin = Fo Lo Work = Work out where in = input and o = output
Fin / Fo = Lo / Lin = 30 / 60 = 1/2 (input force = 1/2 output force)
Lin + Lo = 3
Lo = 3 - Lin
1/2 = (3 - Lin) / Lin from above
1/2 = 3 / Lin - 1
3 / Lin = 1.5 and Lin = 2
So the input length = 2 m and the output length = 1 m

determine the density in kg/m3 of a solid whose mass is 40 and whose dimension in centimetre are 30×4×3
Answer:
Density = 11.11 kg/m³
Explanation:
Given the following data;
Mass = 40 kg
Dimensions = 30×4×3 = 360 cm³ to m³ = 360/100 = 3.6 m³
Thus, volume = 3.6 m³
Now, we can find the density;
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the equation;
[tex]Density = \frac{mass}{volume}[/tex]
Substituting into the equation, we have;
Density = 40/3.6
Density = 11.11 kg/m³
