what is its weight, in lbf, at a location where gravity is 32. 0 ft/s2?
The weight of the object in lbf at a location with gravity 32.0 ft/s2 is 320 lbf (10 lbm x 32.0 ft/s2).
What is gravity?Gravity is a natural phenomenon by which all objects with mass in the universe attract each other. It is the force that keeps us and all other objects on the Earth’s surface and is responsible for the movement of celestial bodies. Gravity is an invisible force that acts on every object in the universe, no matter how small or large. It is the force that gives objects their weight and keeps them in orbit around other objects, such as planets or stars. Gravity is one of the four fundamental forces of nature, along with the strong and weak nuclear forces, and electromagnetism.
The weight of an object is equal to its mass multiplied by the gravitational acceleration at the location.
Therefore, the weight of the object in lbf at a location with gravity 32.0 ft/s2 is 320 lbf (10 lbm x 32.0 ft/s2).

Unlike a roller coaster, the seats in a Ferris wheel swivel so that the rider is always seated upright. An 80-ft-diameter Ferris wheel rotates once every 24 s.
A. What is the apparent weight of a 90 kg passenger at the lowest point of the circle?
Express your answer with the appropriate units.
B. What is the apparent weight of a 90 kg passenger at the highest point of the circle?
Express your answer with the appropriate units.
The apparent weight of the passenger at the lowest point is 90 kg and at the highest point it changes due to the centrifugal force.
What is centrifugal force?
The centrifugal force is an apparent force that is observed in a rotating reference frame. It is the force that appears to push objects away from the center of rotation. It is not a real force, but rather a pseudo-force that is caused by the inertia of an object in motion. In other words, it is the inertia of an object that makes it appear as if there is a force pushing it away from the center of rotation.
A. At the lowest point of the circle, the rider is at the bottom of the Ferris wheel and moving at the same velocity as the wheel. Therefore, the apparent weight of the passenger is equal to the true weight, which is 90 kg.
B. At the highest point of the circle, the rider is at the top of the Ferris wheel and is moving at a slower velocity than the wheel. Therefore, the apparent weight of the passenger is less than the true weight. This effect is known as the centrifugal force. The formula for the apparent weight at the top of the Ferris wheel is:
Apparent weight = True weight x (1 - (v^2/r^2))
where v is the velocity of the Ferris wheel and r is the radius of the Ferris wheel.
In this case, the velocity of the Ferris wheel is (2πr)/T = (2π40ft)/24s = 4.71 ft/s
The radius of the Ferris wheel is 40ft
So, the apparent weight of a 90 kg passenger at the highest point of the circle is:
90 kg x (1 - (4.71^2 / 40^2)) = 90 kg x (1 - 0.12) = 90 kg x 0.88 = 79.2 kg.
Therefore, due to centrifugal force the apparent weight of the passenger at the highest point of the circle is 79.2 kg.

m = 20000 kg = 2 x [tex]10^{4}[/tex]
T = 3.0 x [tex]10^{5}[/tex] N
W = m x g = 20000 x 9.8 = 1.96 x [tex]10^{5}[/tex] N
We just substitute the information above into the formula :
a = [tex]\frac{3.0 x 10^{5} - 1.96 x 10^{5} }{2 x 10^{4} }[/tex]
a = [tex]\frac{1.04 x 10^{5} }{2 x 10^{4} }[/tex]

What do you mean by circuit?A closed loop in which electrons can move called a circuit. Electricity is supplied to the circuit by an electricity source, such as a battery. No electrons will move till the circuit is finished, that is, it goes full circle back to the electrical source.
The combined resistance of the circuit can be calculated by adding the individual resistances in series: 100 ohms + 200 ohms = 300 ohms.
To calculate the current in the circuit, you can use Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R):
I = V / R
In this case, the voltage is 3.0 V, and the resistance is 300 ohms.

you are at the bank of a still river that is 100 m wide. a friend is standing on the opposite side of the river 300 m directly north of the point directly across from where you are. you plan to swim across the river then run along the opposite bank. if you can swim 3 meters per second and run 5 meters per second, then to what point should you swim to minimize your time?
To minimize your time to reach your friend, you should swim to the point directly across from your current position and then run along the opposite bank.
This is because the time you would take to swim to any other point along the opposite bank would be the same (100m / 3m/s = 33.33s) but the distance you would run would be different, and thus the time running would be different.
The time taken to run along the opposite bank is 300m / 5m/s = 60s. So the total time taken to reach your friend would be 33.33s + 60s = 93.33s.

You can start the problem by using the formula for capacitance, C = Q/V, where C is the capacitance, Q is the charge stored on the capacitor, and V is the potential difference across the capacitor.
What are capacitors?A capacitor is a passive electrical component that stores electrical energy in an electric field. It consists of two conductive plates, separated by an insulating material called the dielectric. When a voltage is applied across the conductive plates, an electric field is created, which stores energy in the dielectric. The ability of a capacitor to store electrical energy is measured in farads (F).
Given that Capacitor 2 has half the capacitance and twice the potential difference as Capacitor 1, you can express the capacitance and potential difference of Capacitor 2 in terms of those of Capacitor 1.
C₂ = 1/2 × C₁ V₂ = 2 × V₁
You can use these equations to find the ratio of the stored energy in the two capacitors. The stored energy in a capacitor is given by the formula U = 1/2CV², where U is the stored energy, C is the capacitance, and V is the potential difference.
Uc1 = 1/2C₁V₁² Uc2 = 1/2C₂V₂²
By substituting the values of C₂ and V₂ in terms of C₁ and V₁, you can find the ratio of the stored energy in the two capacitors:

What is kinetic energy?
A type of energy known as kinetic energy is connected to an object's motion. It is the energy that an object possesses as a result of its motion. Kinetic energy is directly related to the mass of the object and its velocity. The kinetic energy of an object is calculated by multiplying half of the mass of the object by the square of its velocity.
The formula for kinetic energy is KE = ½ mv2, where m is the mass of the object and v is the velocity of the object. Kinetic energy is a form of energy that is transferable; it can be transferred from one object to another. This can be seen when two objects collide with each other and energy is transferred from one object to the other.
The Kinetic energy = 1/2m v²
Given Mass is same, so we get rid of mass

Determine the time needed to pull the cord at B down 4 ft starting from rest when a force of 10 lb is applied to the cord. Block A weighs 20 lb. Neglect the mass of the pulleys and cords.
The time needed o pull the cord at B down 4 ft starting from rest is 0.249s .
What does a pulley's tension mean?At its two ends, tension is the pulling force applied to the object attached to its ends by the ropes at its ends. Tension is the pulling force put on the rope (or string, cable, or chain) on one side of the point by the rope on the other.
2Ta - Wa = ma a1
40-20 = 20 a1
a1 = 32.2 ft/s^2
a2 = -4 x 32.2
=> 128.8 ft /s^2.
s=ut + 1/2 a t^2;
u=0;
4= 0+ 1/2 x 128.8 x t^2
=> time t= 0.249 sec.
What is tension, exactly?The force imparted through a rope, string, or wire when both opposing forces strain on it is described as tension. The tension force draws energy proportionately on the objects at the ends and is applied along the entire length of the wire. Every physical object in contact with another one applies some force to that object.

a certain 48 v electric forklift can lift up to 7000 kg at a maximum rate of 75 meters per minute. what is its power? round your answer to the nearest hundreds.
In this case the power is 703.8 kW and rounding to the nearest hundreds gives 700 kW.
What is power?
Power is the ability to influence or control people, events, and outcomes. It can be seen when one person or group is able to make decisions, set standards, and enforce boundaries. Generally, power is associated with authority, control, and influence; however, it can also refer to the capacity to do work or generate energy.
The power of the forklift can be calculated using the formula: Power = (Load x Velocity) / Time.
In this case, the power is (7000 kg x 75 m/min) / 1 min = 525,000 kg•m/min. Converting to watts, this is 525,000 kg•m/min / 746 = 703.8 kW.
Rounding to the nearest hundreds gives 700 kW.
In this case the power is 703.8 kW and rounding to the nearest hundreds gives 700 kW.
