A man is using a fishing rod to catch fish in figure 1.
Figure 2 is a simplified diagram of figure 1 with the forces and distances.
Calculate the force F, in figure 2.
Answer:
Explanation:
Remark
In general, these 3rd class levers are very inefficient. Because the force distance is smaller than the load distance, you need to pull upward with more force that the weight of the load. So whatever the load is, the force is going to be much greater.
The distances are always measured to the pivot unless you are asked something specific otherwise.
Givens
F = ?
weight = 6N
Force Distance = F*d = 0.5 m
Weight Distance =W*d1 = 2 m
Formula
F*Fd = W*Wd
Solution
F*0.5 = 6 * 2 Divide by 0.5
F = 12/0.5
F = 24 N upwards

TRUE or FALSE: An object's mass changes depending on which planet it is located.
A. TRUE
B. FALSE
Answer:
Fales
Explanation:
That's why scientists and engineers often measure an object's mass—how much matter the object contains—rather than its weight. Mass stays the same regardless of location and gravity. You would have the same mass on Mars or Jupiter as you do here on Earth. Your weight is different on other planets due to gravity.

The air going into the tyre was warmed up by the pumping. What effect will this have on the motion of Gad molecules in the air in the tyre?
Answer:
they are constantly bouncing everywhere and creating preasure
Explanation:
The motion of gas molecules in the air in the tyre will speed up.
What is motion of molecules?Molecular motion is defined as the movement of molecules in a certain direction. The molecular motions are affected by heat and temperature. This is because the temperature is the measurement of the average kinetic energy of the molecules and represents the motion of molecules.
What is kinetic energy?The kinetic energy of an object is the energy which it possesses due to its motion. It gives the work needed to accelerate a body of a given mass from rest to its stated velocity. To calculate kinetic energy
[tex]K.E = \frac{1}{2} mv^{2}[/tex]
Kinetic energy depends on the velocity of the object which means that when the velocity of an object doubles, its kinetic energy quadruples.
Kinetic energy must always be either zero or a positive value.
Kinetic energy is not a vector.
The gas molecules inside the tyre exert pressure on the walls of the tyre as the molecules collide with the walls of the tyre.
When the air in the tyre becomes hotter, the pressure rises as more collisions.
The pressure in the tyre increases as there will be more frequent collisions with the tyre wall.

Which kind of force(s) cause acceleration?
Answer:
unbalanced force,
Explanation:
The bigger the unbalanced force acting on the object the bigger the acceleration of the object. The more mass the object has, the more inclined it is to resist any change to its motion.

According to Newton’s second law of motion, what is equal to the acceleration of an object?
Answer:. The acceleration of the object is directly proportional to the force and inversely proportional to the mass.
Explanation:
According to Newton s Second Law of Motion, also known as the Law of Force and Acceleration, a force upon an object causes it to accelerate according to the formula net force = mass x acceleration.
calculate capacitance if Q=7mc and delta V=12V
Answer:
Capacitance = 0.00058 Farads
Explanation:
Given the following data;
Charge, Q = 7mC to Coulombs = 7/1000 = 0.007C
Velocity = 12V
To find the capacitance;
Capacitance = charge/potential difference
Substituting into the equation, we have;
Capacitance = 0.007/12
Capacitance = 0.00058 Farads
