Hence, R = 28.97 m, 24.5 degrees is the vector sum of T and U.

A vector's direction is frequently stated as a rotation of the vector's "tail" anticlockwise with respect to due East. In accordance with this practise, a vector having a direction of 30 degrees is a vector that has been anticlockwise rotated 30 degrees with respect to due east.

Let's begin by separating the components of the vector T:

T~ = 40 m, 30 degrees

T_x = 40 cos(30) = 34.64 m

T_y = 40 sin(30) = 20 m

Let's now decompose the vector U into its constituent parts:

U~ = 12 m, 225 degrees

U_x = 12 cos(225) = -8.49 m

U_y = 12 sin(225) = -8.49 m

It is possible to combine elements of the same type (x and y):

R_x = T_x + U_x = 34.64 m - 8.49 m = 26.15 m

R_y = T_y + U_y = 20 m - 8.49 m = 11.51 m

The Pythagorean theorem can be used to determine the size of the resulting vector R:

|R~| = sqrt(R_x² + R_y²) = sqrt((26.15 m)² + (11.51 m)²) = 28.97 m

The inverse tangent function can be used to determine the direction of the resulting vector R:

theta = tan⁻¹(R_y/R_x) = tan⁻¹(11.51 m/26.15 m) = 24.5 degree.

Answer:

If a runner exerts 350 J of work to generate 175 W of power, it took the runner 2 seconds to do the work.

Explanation:

Power is defined as the speed with which a job is done. In other words, power is a given amount of work done in a given unit of time. That is, it is the amount of work per unit of time that some object or system produces.

Its expression is:

\(P=\frac{W}{t}\)

where:

In this case:

Replacing:

\(175 W=\frac{350 J}{t}\)

and solving you get:

\(t=\frac{350 J}{175 W}\)

t= 2 s

If a runner exerts 350 J of work to generate 175 W of power, it took the runner 2 seconds to do the work.

Answer: Displacement is 165 km in N076°W

If a car drives 40 kilometers west, and then 160 kilometers north then the final displacement of the car would be 164.92 kilometers in the northwest direction.

Displacement describes this shift in location. The final displacement of any object is given by the final position of the object subtracted bt the initial position of the object.

As given in the problem we have to find the final displacement of the car if the drives 40 kilometers west, and then 160 kilometers north,

The final displacement of the car = √(40² + 160²)

                                                       = 164.92 kilometers

Thus, an automobile would go 164.92 kilometers northwestward if it traveled 40 kilometers west, 160 kilometers north, and then 40 kilometers east.

So, the speed of the ball after 2 seconds after free fall is 20 m/s.

Hi ! I'm Deva from Brainly Indonesia. In this material, we can call this event "Free Fall Motion". There are two conditions for free fall motion, namely falling (from top to bottom) and free (without initial velocity). Because the question only asks for the final velocity of the ball, in fact, we may use the formula for the relationship between acceleration and change in velocity and time. In general, this relationship can be expressed in the following equation :

\( \boxed{\sf{\bold{a = \frac{v_2 - v_1}{t}}}} \)

With the following conditions :

We know that :

What was asked :

Step by step :

\( \sf{a = \frac{v_2 - v_1}{t}} \)

\( \sf{(a \times t) + v_1 = v_2} \)

\( \sf{(10 \times 2) + 0 = v_2} \)

\( \boxed{\sf{v_2 = 20 \: m/s}} \)

So, the speed of the ball after 2 seconds after free fall is 20 m/s.

Answer:

Height ball A will deflect the target is 2.65 m

Height ball A will deflectthe target is 2.2 m

Ball A, will deflect the target to greater height, thus i will throw ball A

Explanation:

Given;

mass of the target, m₁ = 5.00 kg

mass of the ball, m₂ = 1.5 kg

initial velocity of each throw, u = 12 m/s

Throwing ball A; apply the principle of conservation linear momentum for elastic collision;

m₁u₁ + m₂u₂ = v₁m₁ + v₂m₂

The initial velocity of the target, u₁ = 0

The ball bounced back at the same speed, v₂ = -12 m/s

the velocity of the target after collision, = v₁

0 + 1.5 x 12 = v₁(5) + (-12 x 1.5)

18 = 5v₁ - 18

18 + 18 = 5v₁

36 = 5v₁

v₁ = 36/5

v₁ = 7.2 m/s

The vertical height reached by the target is given by;

v₁² = u₁² + 2gh

v₁² = 0 + 2gh

v₁² = 2gh

h = v₁² / 2g

h = (7.2)² / (2 x 9.8)

h = 2.65 m

Throwing ball B; apply the principle of conservation energy for the inelastic collision;

the kinetic energy of the ball will be converted to the potential energy of the target.

¹/₂m₁u₂² = mgh

¹/₂(1.5)(12)² = (5 x 9.8)h

108 = 49h

h = 108 / 49

h = 2.2 m

Ball A will deflect  the target to greater height, thus i will throw ball A.

Explanation:

The mechanical advantage of that pulley is 10.

The force amplified by utilizing a tool, mechanical device, or machine system is known as mechanical advantage. To achieve the desired output force amplification, the gadget trades off input forces against movement. The law of the lever serves as a paradigm for this.

Mechanisms are machine parts made to control forces and motion in this way.

Given that: the weighs of the object: W = 100 Newton.

Applied force: F = 10 N.

For using a pulley, you have to apply a force of 10 Newtons to lift  an object that weighs 100 Newtons.

Hence, the mechanical advantage of the pulley is

The total resistance of the circuit is 49 Ω. The current strength in the circuit, when connected to a voltage source of 56 V, is approximately 1.14 A.

To calculate the total resistance of the circuit, we need to determine the equivalent resistance of the resistors connected in a series.

Given:

R1 = 4 Ω

R2 = 30 Ω

R3 = 10 Ω

R4 = 5 Ω

Calculate the equivalent resistance (RT) of R1 and R2, as they are connected in series:

RT1-2 = R1 + R2

RT1-2 = 4 Ω + 30 Ω

RT1-2 = 34 Ω

Calculate the equivalent resistance (RTotal) of RT1-2 and R3, as they are connected in parallel:

1/RTotal = 1/RT1-2 + 1/R3

1/RTotal = 1/34 Ω + 1/10 Ω

1/RTotal = (10 + 34) / (34 * 10) Ω

1/RTotal = 44 / 340 Ω

1/RTotal ≈ 0.1294 Ω

RTotal ≈ 1 / 0.1294 Ω

RTotal ≈ 7.74 Ω

Calculate the equivalent resistance (RTotalCircuit) of RTotal and R4, as they are connected in series:

RTotalCircuit = RTotal + R4

RTotalCircuit = 7.74 Ω + 5 Ω

RTotalCircuit ≈ 12.74 Ω

Therefore, the total resistance of the circuit is approximately 12.74 Ω.

To determine the current strength (I) when connected to a voltage source of 56 V, we can use Ohm's Law:

I = V / RTotalCircuit

I = 56 V / 12.74 Ω

I ≈ 4.39 A

Therefore, the current strength in the circuit, when connected to a voltage source of 56 V, is approximately 4.39 A (or 1.14 A, considering significant figures).

After multiple contacts with the charged ball, the charge on the rod will be arranged so that the net charge of the rod is zero.

This is because the ball is a conductor, so when it contacts the rod, the charge will spread out evenly over the rod. The rod will then have an equal amount of positive and negative charge.

Electrical charge is the physical property that causes objects to experience a force when they are in an electric field. It is the charge on an object that causes it to be attracted to or repelled from other objects. Positively charged objects will be attracted to negatively charged objects and vice versa. Electrical charge is measured in coulombs, which is the amount of charge that flows through a conductor when a current of one ampere flows for one second.

Answer:

ΔQ = 5054 KJ/kg.K

Explanation:

First of all, we will find the value of the specific heat of hydrogen. Since it is mentioned that the value of specific heat is constant between 300 K and 650 K. Therefore, we can take it to be the average of values at these two temperatures.

\(Constant\ Specific\ Heat\ of\ Hydrogen = C = \frac{Specific\ Heat\ at\ 300\ K + Specific\ Heat\ at\ 650\ K}{2} \\C = \frac{(14.31 + 14.57)KJ/ kg.K}{2}\)C = 14.44 KJ/ kg.K

Now, the heat absorbed is given by the following formula:

\(\Delta Q = C(T_{f} - T{i})\)

where,

T_f = Final Temperature = 650 K

T_i = Initial Temperature = 300 K

\(\Delta Q = (14.44\ KJ/kg.K)(650\ K - 300\ K)\\\)

ΔQ = 5054 KJ/ kg.K

Answer:

a)   Em_f = ½ m vₐ²,  b)    v = vₐ /√2

Explanation:

a) For this part we use conservation of energy

   starting point .. block A moving, spring unstretched

          Em₀ = K = ½ m vₐ²

end point. Stretched spring

          Em_f = K_e = ½ k x²

energy is conserved

          Em₀ = Em_f

          Em_f = ½ m vₐ²

b) Let's analyze the movement a little, block A began to move at a speed va, I stretch the spring an amount Dx, it exerts a force on block b that begins to move and the elongation of the spring decreases.

In all this process there is no friction force, therefore the energy is conserved, therefore the maximum energy stored in the spring must be distributed among the bodies.

           Em₀ = K_e = E₀

where E₀ is the initial energy of block a

            E₀ = ½ m vₐ²

At the point where we are in equilibrium

          Em_f = Kₐ + K_b = ½ m vₐ² +1/2 m \(v_{b}^2\)

so that the spring does not stretch or shrink, the two bodies must go at the same speed.

          Em_f = m v²

energy is conserved

          Em₀ = Em_f

          ½ m vₐ² = m v²

           v = vₐ /√2

therefore both blocks must go at this speed

The wavelength of light that should be used to obtain fringes that are 0.0045 m wide after reducing the distance between the screen and the slit by half is 2.25 * 10^7 Å.

Huygens's Principle states that every point on a wavefront can be considered as a source of secondary spherical wavelets that spread out in all directions with the same speed as the original wave. The new wavefront is formed by the envelope of these secondary wavelets at a later time.

Now, let's consider a Young's double-slit experiment. In this experiment, when light passes through two narrow slits, it creates an interference pattern on a screen behind the slits. The fringe width is the distance between two consecutive bright or dark fringes in the pattern.

Given that the fringe width obtained is 0.6 cm and the wavelength of light used is 4500 Å (Angstroms), we can calculate the wavelength of light required to obtain fringes that are 0.0045 m wide.

We can use the formula for fringe width in Young's double-slit experiment:

w = (λ * D) / d

Where:

w is the fringe width,

λ is the wavelength of light,

D is the distance between the screen and the double slits, and

d is the distance between the two slits.

Let's calculate the value of D/d using the given information:

D/d = w / λ

= 0.006 m / 4500 Å (1 m = 10^10 Å)

= 0.006 * 10^10 / 4500 m^-1

Now, if the distance between the screen and the slit is reduced by half, the new value of D/d would be:

(D'/d) = (0.006/2) * 10^10 / 4500 m^-1

Now, we can rearrange the equation to solve for the new wavelength (λ'):

(λ' * D') / d = (D/d)

λ' = (D/d) * d / D

= [(0.006/2) * 10^10 / 4500] * (4500 / 0.006) Å

= 0.0045 m * 10^10 / 2 Å
