What is the gravitational force that two objects would feel if they are 3.5 meters apart? Object 1 has a mass of 10x10^5 kg and object 2 has a mass of 3x10^5 kg?
Answer:
1.63 N
Explanation:
F = GMm/r^2
= (6.67x10^-11)(10x10^5)(3x10^5) / 3.5^2
= 1.63 N ( 3 sig. fig.)
A hydraulic jack has an output piston
of area 0.100 m2. A 55.8 N input force
creates 419 N of output force. What is
the area of the input piston?
Answer:
Explanation:
You want the area of the output piston not the input piston. The input piston creates a pressure equal to
55.8 N/0.1 m^2 = 558 N/m^2. This pressure is transmitted through the hydraulic fluid and applied to the output piston. The pressure exerted on the output piston is equal to 419 N/Am^2. Set this equal to the applied pressure and solve for A, the area of the output piston.
419/A = 558 , A = 419/558 = 0.751 m^2
Answer:
0.0133 m^2
Explanation:
55.8/419=0.133
0.133*0.100= 0.0133
Hope this helps!

In a television tube the picture is formed by streams of electrons hitting the screen. The current is 20 mA. How much electric charge hits the screen in 30 minutes?
Answer:
Quantity of charge = 36 Coulombs.
Explanation:
Given the following data;
Current = 20 mA = 20/1000 = 0.02 Amperes
Time, t = 30 minutes to seconds = 30 * 60 = 1800 seconds
To find the quantity of charge;
Quantity of charge = current * time
Quantity of charge = 0.02 * 1800
Quantity of charge = 36 Coulombs.

an object is realsed From rest . how far does it fall during the second second of fall?
Answer:
14.715 m
Explanation:
Assume that the acceleration due to gravity is 9.81 m/s^2 downwards, take downwards as positive
First second:
v = u + at
v = 9.81 m/s
Second second:
s = ut + (1/2)at^2
s = 9.81(1) + (1/2)(9.81)(1)^2
s = 14.715 m
BY what factor does the kinetic energy of a moving body change when its speed is reduced to half? please help i have an exam and i need an answer
Answer:
Kinetic Energy = 1/2 mass*velocity^2
K=1/2mv^2
Therefore if you reduce the speed of an object by 1/2, K reduced to 1/4 its value.
Dos cargas puntuales se localizan en el eje +X de un sistema de coordenadas. La carga q1= 1nC esta a 2cm del origen y la carga q2= -3 nC esta a 4cm del origen. ¿cual es la fuerza tras que ejercen estas dos cargas sobre una carga q3= 5nC que se encuentra en el origen?
Answer:
F_net = 1.125 10⁻⁶ N
positive direction of the x axis
Explanation:
The electric force is given by Coulomb's law
F =[tex]k \frac{q_1q_2}{r_{12}^2}[/tex]
also used charge of equal sign repel each other.
We appease this information to our problems
the charge q₁ is positive and the charge q₃ is positive for which the force is repulsive; ; a charge q₂ is negative so the force is attractive.
If we apply that the forces are vectors
F_net = - F₁₃ + F₂₃
F_net = [tex]-k \frac{q_1q_3}{r_{13}^2} + k \frac{q_2q_3}{r_{23}^2}[/tex]
F_net = k q₃ ( [tex]- \frac{q_1}{r_{13}^2} + \frac{q_2}{r_{23}^2}[/tex] )
let's look for the distances
r₁₃ = 2-0 = 2 cm = 2 10⁻² m
r₂₃ = 4-0 = 4 cm = 4 10⁻² m
let's substitute
F_net = 9 10⁹ 5 10⁻⁹ ( [tex]- \frac{1 \ 10^{-9}}{2 \ 10^{-2}} + \frac{3 \ 10^{-9}}{4 \ 10^{-2}}[/tex])
F_net = 45 (- 0.5 10⁻⁷ + 0.75 10⁻⁷)
F_net = 1.125 10⁻⁶ N
the positive sign indicates that the outside has a positive direction of the x axis, that is, it is to the right
Calculate the energy absorbed when 13 kg of liquid water raises from 18°C to 100°C and then boils at 100°C.
Answer:
the energy absorbed is 4.477 x 10⁶ J
Explanation:
mass of the liquid, m = 13 kg
initial temperature of the liquid, t₁ = 18 ⁰C
final temperature of the liquid, t₂ = 100 ⁰C
specific heat capacity of water, c = 4,200 J/kg⁰C
The energy absorbed is calculated as;
H = mcΔt
H = mc(t₂ - t₁)
H = 13 x 4,200(100 - 18)
H = 4.477 x 10⁶ J
Therefore, the energy absorbed is 4.477 x 10⁶ J

Electric current flows through paths called circuits. People often build circuits using wires, resistors, and batteries. A battery is a voltage source.
A circuit with which components has the highest current with the given voltages?
wires, a 9V battery, no resistors
wires, a 9V battery, a light bulb
wires, a 1.5V battery, no resistors
wires, a 1.5V battery, a light bulb
Answer:the answer is A. Wires, a 9v battery, no resistors
Explanation:
A wire with battery of the voltage of 9 volts with no resistor has the highest value of current. The ampere is the SI unit for electric current.
What is electric current?The pace at which electrons travel through a conductor is known as electric current. Electrons are tiny particles that reside within a substance's molecular structure.
Ohm's law claims that the voltage across a conductor is directly proportional to the current flowing through it.
The Equation of Ohm's Law
V=IR
If there is no resistor, the resistance in the circuit is zero, results in the highest value of electric current.
Voltage is directly proportional to the current. As high the value of voltage, the value of the electric current is high.
Hence, a wire with battery of the voltage of 9 volts with no resistor has the highest value of current.

I wanna give points so my question,
What is gravity?
Answer:
An invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall. ... Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Earth's gravity comes from all its mass.
Explanation:
thx for the points :)
Answer:
gravity is the force that attracts a body toward the center of the earth or toward any other physical body having mass.
Explanation:
If the displacement of a particle is given by the formula S = 3t^3 - 20t^2 + 40t. Find (i) the displacement after 3 seconds (ii) the formula for the velocity at any time t (iii) the value of t when the particle is not moving (iv) the initial velocity of the particle (v) the formula for the acceleration at any time t (vi) the initial acceleration of the particle.
Answer:
At t = 0 S = 0
S = 3 * 3^3 - 20 * 3^2 + 40 * 3 after 3 sec
S = 3 * 27 - 20 * 9 + 120 = 21 after 3 sec
v = ds/dt = 9 * t^2 - 40 * t + 40 = 9 * 9 - 40 * 3 + 40 = 1
ds/dt = 9 t^2 - 40 t + 40 v at any time
If zero = 9 t^2 - 40 t + 40 then you need to solve the quadratic for t
a = ds^2 / dt^2 = dv /dt = 18 t - 40 for the acceleration at any time
At t = zero (the initial acceleration) a = -40

In the following figure, a table of mass 0.44 Kg is pushed against an inclined surface with a 15 inclination angle. Find the amount of the horizontal component of the Weight
Answer:
W = 1.11 N
Explanation:
Given that,
Mass of a table, m = 0.44 kg
It is pushed against an inclined surface with a 15 inclination angle.
We need to find the amount of the horizontal component of the weight. The horizontal component of weight is given by :
[tex]W=mg\sin\theta\\\\W=0.44\times 9.8\times \sin(15)\\\\W=1.11\ N[/tex]
So, the amount of the horizontal component of the weight is 1.11 N.

If F=ma, then if Security removes a 20 kg misbehaving child out of a
classroom 15 m/s to the Principal's office. What is the amount of force the
security guard used? *
1.33 N
300 N
2.55 N
30 N
Answer:
Force = 300N
Explanation:
Given the following data;
Mass = 20kg
Acceleration = 15m/s²
To find the force?
Force is given by the formula;
Force = mass * acceleration
Substituting into the equation, we have;
Force = 20 * 15
Force = 300N
Therefore, the amount of force the
security guard used is 300 Newton.
