Explanation:

a)

Answer:

Using Pythagorean Theorem.

[tex]F_{R} = \sqrt{Fn^{2} + Fe^{2} } \\\\ F_{R} = \sqrt{52.7^{2} + 91^{2} }\\\\ F_{R} = 105.16N[/tex]

b)

Answer:

[tex]tan^{-1} \frac{opp}{adj} \\ \\ tan^{-1} \frac{52.7}{91} \\ \\ = 30.08^{o}[/tex]

The resultant force of the two forces which are acting perpendicular to each other is 105.15 N and the direction is 59.91 ° from east.

Force is an external agent acting on a body to change it from the state of motion or rest. If two forces acting on a body and both are applied in the same direction, the resultant force will be the sum of two forces in magnitude.

If the two forces are in opposite directions, then the resultant force will be the substracted value of their magnitude. If one force is to the north and other is to the east, then they are perpendicular to each other.

Hence, to find the resultant force we can use the Pythagoras theorem for right angled triangle. The hypotenuse will be the resultant force.

Resultant force = √ (52.7² + 91² )

                          = 105. 15 N.

The direction of the force = Tan ⁻¹ (91 / 52.7 )

                                           = 59.91 ° from east to north.

Hence, the resultant force is 105.15 N with a direction of 59.91 ° from east.

Answer:

Below

Explanation:

Here is what we are given in the problem :

dy = - 1.0 m (this is negative because the cat falls)

Vx = 5.0 m/s

We can use this equation to find the time that it will take the cat to fall :

     t = √-2dy / g

     t = √-2(-1.0) / 9.8

     t = √0.20408

     t = 0.45 (round this to 2 sig figs)

    t = 0.5 seconds

Now we can find dx (distance in the x direction)

     dx = vx (t)

     dx = (5.0m/s)(0.45s)

     dx = 2.258769 m

     dx = 2.3 m

Le due rette rappresentano le leggi del moto di due punti

materiali (per esempio due macchine) che si muovono di moto

rettilineo uniforme. La retta meno pendente (velocità più bassa)

è riferita alla macchina che parte da una posizione iniziale più

avanti rispetto alla seconda macchina. Però, la seconda

macchina, avendo una velocità maggiore della prima (retta più

pendente), nonostante parta più indietro rispetto alla prima, dopo

un certo tempo la raggiungerà. Pertanto, il punto P, intersezione

delle due rette, rappresenta la situazione fisica in cui la seconda

macchina raggiunge la prima. In particolare, le coordinate del

punto P (tempo e spazio), rappresentano l’istante e la posizione

in cui la seconda macchina raggiunge la prima.

The distances traveled by the boy will be 4 m. Newton's second equation of motion is applied.

Distance is a numerical representation of the distance between two objects or locations.

The distance can refer to a physical length or an estimate based on other factors in physics or common use. |AB| is a symbol for the distance between two points A and B.

Given data;

acceleration(a)=2m/s²

Time (t)=2 s

u(Initial velocity)=0

The distance traveled by the boy will be;

[tex]\rm S=ut+\frac{1}{2} at^2 \\\\ \rm S=0+\frac{1}{2} (2)(2)^2 \\\\ S=4 \ m[/tex]

Hello!

We can begin by summing the forces acting on each mass. (Tension is CONSTANT because the string is both frictionless and massless).

On the 3 kg block: (Ignore forces acting in the vertical direction since there is no motion in that axis)

∑F = -M₁gsinФ + T

On the 8 kg block:

∑F = -T + M₂g

Sum the forces:

∑F = -M₁gsinФ + T -T + M₂g

∑F = -M₁gsinФ + M₂g

Divide by both masses to get the acceleration:

[tex]a = \frac{-M_1gsinФ + M_2g}{m_1+m_2}[/tex]

Plug in values: (g = 10m/s²)

[tex]a = \frac{-(3)(10)(sin30)+8(10)}{3+8} = 5.91 m/s^2[/tex]

The kinematics allows finding the result for the height of the cliff so that the bodies go down together is: 1,533 m

Kinematics studies the movement of bodies, finding relationships between the position, velocity and acceleration of bodies

In this case the bodies are thrown vertically so their acceleration is the gravity acceleration, directed downwards.

Let's set a reference system with the positive upward direction and zero at the base of the cliff, let's use the subscript 1 for the body that comes out from the bottom of the cliff and the subscript 2 for the body that comes out of the top, the equations for each body they are:

body 1

            [tex]v_1^2 = V_{o1}^2 - 2g (y_1-y_{o1} )[/tex]

body 2

             [tex]v_2^2 = v_{o2}^2 - 2g (y_2-y_{o2})[/tex]

In this case they indicate the initial velocities of each body, [tex]v_{o1}[/tex] = 80 m/s and [tex]v_{o2}[/tex] = 50 m/s, the initial height [tex]y_{o1}[/tex] = 0 and [tex]y_{o2}[/tex] = h, when the bodies fall at the same time they must begin to descend from the same height

            y₁ = y₂

The velocities at this point must be zero

          v₁ = v₂ = 0

We substitute

            0 = [tex]v_{o1}^2 - 2 g y[/tex]

            0 = [tex]v_{o2}^2 - 2 g ( y + h)[/tex]  

Let's solve the system of equations

            [tex]h = \frac{v_{o1} - v_{o2}}{2g}[/tex]  

Let's calculate

            h = [tex]\frac{80-50}{2 \ 9.8}[/tex]

            h = 1.53 m

Consequently, the kinematics allows finding the result for the height of the cliff so that the bodies go down together is: 1.53 m

Explanation:

The gravitational force equivalent, or, more commonly, g-force, is a measurement of the type of force per unit mass – typically acceleration – that causes a perception of weight, with a g-force of 1 g equal to the value of gravitational acceleration on Earth, g, of about 9.8 m/s².

Answer:

When the temperature drops from 0°C to 4°C, water expands instead of contracting, resulting in a reduction in density. In solid form, water molecules normally form open crystal structures, so as they freeze, their density decreases.

When liquids cool, they constrict and become denser. This is not the case with water. Upon cooling to 4°C, it contracts, but upon reaching 0°C, it begins to expand and becomes ice. Thus, it becomes denser as it cools.
