Force is defined as the push or pull applied to the body. Its unit is Newton. The net force will be 10 N on the right side.

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;

F₁ is forced by person 1 = 100 N

F₂ is forced by person 2= 90 N

Fₓ is the net force

Fₓ = F₁ -F₂

Fₓ = 100-90

Fₓ= 10 N

Hence the net force will be 10 N on the right side.

Explain Resistor in parallel and series.

patriot [66]

$\sf\huge\underline\blue{Resistor:-}$

$\rightarrow$ A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element.

$\rightarrow$ Resistors reduce the current flow and lower voltage levels within circuits.

$\sf\large\underline\purple{Resistors \:in\: Series:-}$

$\rightarrow$ A circuit is said to be connected in series when the same amount of current flows through the resistors. In such circuits, the voltage across each resistor is different.

$\rightarrow$ In a series connection, if any resistor is broken or a fault occurs, then the entire circuit is turned off. The construction of a series circuit is simpler compared to a parallel circuit.

$\rightarrow$ For the above circuit(attached image-1), the total resistance is given as:

$\sf{R_{total}\: = \:R1 + R2 + ….. + Rn}$

The total resistance of the system is just the total of individual resistances.

$\sf\large\underline\purple{Resistors \:in\: Parallel:-}$

$\rightarrow$ A circuit is said to be connected in parallel when the voltage is the same across the resistors. In such circuits, the current is branched out and recombines when branches meet at a common point.

$\rightarrow$ A resistor or any other component can be connected or disconnected easily without affecting other elements in a parallel circuit.

$\rightarrow$ The figure(attached image -2) above shows ‘n’ number of resistors connected in parallel. The following relation gives the total resistance here

$\sf{\frac{1}{R_{total}}\: = \:\frac{1}{R1} + \frac{1}{R2} + ….. + \frac{1}{Rn}}$

$\rightarrow$ The sum of reciprocals of resistance of an individual resistor is the total reciprocal resistance of the system.

A ship going from sea water to river water has to displace more water to (a) change the buoyant force (b) decrease the buoyant f

grin007 [14]

Answer:

Change, or increase, the buoyant force.

Explanation:

As the salt water of the sea is denser than the river's fresh water, the boat will rise when entering the sea from the river and sink (to increase the buoyant force) when entering the river from the sea.

The strings in a compound bow behave approximately like a

Pepsi [2]

The speed at which the arrow would be launched is 133.42 m/s

The work-energy theorem asserts that the net work done applied by the forces on a particular object is equivalent to the change in its kinetic energy.

The equation for the work-energy theorem can be computed as:

$\mathbf{W =\Delta K.E}$

$\mathbf{F\Delta x =\dfrac{1}{2} mv^2}$

where;

Force (F) = 267 N
distance Δx = 0.60 m
mass (m) = 18 g
speed (v) = ???

From the above equation, let make speed(v) the subject of the formula:

∴

$\mathbf{v = \sqrt{\dfrac{2(F \Delta x)}{m}} }$

$\mathbf{v = \sqrt{\dfrac{2(267 \times 0.60)}{0.018}} }$

v = 133.42 m/s
