d. Direction and magnitude

Explanation:

The two components of a vector are its magnitude and direction.

Magnitude is the quantity of the substance

Direction is the path.

Examples of vector quantities are velocity, displacement, acceleration.

The force of the spring can be calculated as follow 117.6 N. and the spring constant can be calculated as follows 8.75 N/m.

Force is a physical concept that describes the action of an object on another object. It is the result of an interaction between two or more objects and is related to the strength and direction of a force. Force is a vector quantity, meaning it has both magnitude and direction. Examples of forces include gravity, friction, and electro-magnetic force. Force can cause an object to change its shape, speed, or direction.

A. The force of the spring is 117.6 N with explanation:
The force of the spring can be calculated by using the equation F = kx, where F is the force of the spring,
k is the spring constant, and
x is the displacement of the spring.
In this case, the displacement x is 16 cm (36 cm - 20 cm).
Thus, the force of the spring can be calculated as follows: F = 3.4 N/m * 16 cm = 117.6 N.

B. The spring constant is 8.75 N/m with explanation:
The spring constant can be calculated by using the equation k = F/x,
where k is the spring constant,
F is the force applied to the spring, and x is the displacement of the spring. In this case,
the force F is 7 N and the displacement x is 0.3 m (0.8 m - 0.5 m).
Thus, the spring constant can be calculated as follows: k = 7 N/ 0.3 m = 8.75 N/m.

Answer:

4161 J/kg·°C

Explanation:

We can use the principle of conservation of energy to solve this problem, which states that the total heat energy in a closed system is constant. The heat lost by the tea is equal to the heat gained by the milk.

Let's first calculate the heat lost by the tea:

Q(tea) = mcΔT

Q(tea) = (0.27 kg)(3910 J/kg·°C)(90.0°C - 85.0°C)

Q(tea) = 6555 J

where m is the mass of tea, c is the specific heat of tea, and ΔT is the change in temperature.

Next, let's calculate the heat gained by the milk:

Q(milk) = mcΔT

Q(milk) = (0.02 kg)(c)(85.0°C - 6.0°C)

Now we can equate the two expressions:

Q(tea) = Q(milk)

6555 J = (0.02 kg)(c)(79.0°C)

Solving for c, we get:

c = 4161 J/kg·°C

Therefore, the specific heat of milk is approximately 4161 J/kg·°C.

Explanation:

(a) In order to calculate the magnitude of the worker's force, you take into account that if the ice block slides down with a constant speed, the sum of forces, gravitational force and work's force, must be equal to zero, as follow:

\(F_g-F_w=0\)        (1)

Fg: gravitational force over the object

Fw: worker's force

However, in an incline you have that the gravitational force on the object, due to its weight, is given by:

\(F_g=Wsin\theta=Mg sin\theta\)       (2)

M: mass of the ice block = 39 kg

g: gravitational constant =  9.8m/s^2

θ: angle of the incline

You calculate the angle by using the information about the distance of the incline and its height, as follow:

\(sin\theta=\frac{0.74m}{2.8m}=0.264\\\\\theta=sin^{-1}(0.264)=15.32\°\)

Finally, you solve the equation (1) for Fw and replace the values of all parameters:

\(F_w=F_g=Mgsin\theta\\\\F_w=(39kg)(9.8m/s^2)sin(15.32\°)=101.01N\)

The worker's force is 101.01N

(b) The work done by the worker is given by:

\(W=F_wd=(101.01N)(2.8m)=282.82J\)

(c) The gravitational force on the block is, without taking into account the rotated system for the incline, only the weight of the ice block:

\(F_g=Mg=(39kg)(9.8m/s^2)=382.2N\)

The gravitational force is 382.2N

(d) The normal force is:

\(N=Mgcos\theta=(39kg)(9.8m/s^2)cos(15.32\°)=368.61N\)

(e) The speed of the block when it slides down the incle is constant, then, by the Newton second law you can conclude that the net force is zero.

Answer:

i think your answer is this: the objects have no interactive with each other.

Explanation:

if you think about it tissue paper doesn't really have a static electrical charge if it does it is very weak so therefore cannot really attract or repel anything.

Answer and Explaination:

To solve this problem, we can analyze the forces acting on the mass as it travels up the inclined plane. We'll consider the gravitational force and the force exerted by the spring.

1. Gravitational force:

The force due to gravity can be broken down into two components: one perpendicular to the inclined plane (mg * cosθ) and one parallel to the inclined plane (mg * sinθ), where m is the mass and θ is the angle of the inclined plane.

2. Force exerted by the spring:

The force exerted by the spring can be calculated using Hooke's Law, which states that the force exerted by a spring is directly proportional to the displacement from its equilibrium position. The force can be written as F = -kx, where F is the force exerted by the spring, k is the spring constant, and x is the displacement from the equilibrium position.

Given:

Mass (m) = 5.0 kg

Compression of the spring (x) = 20.0 cm = 0.20 m

Angle of the inclined plane (θ) = 30°

First, let's find the force exerted by the spring (F_spring):

F_spring = -kx

To find k, we need the spring constant. Let's assume that the spring is ideal and obeys Hooke's Law linearly.

Next, let's calculate the gravitational force components:

Gravitational force parallel to the inclined plane (F_parallel) = mg * sinθ

Gravitational force perpendicular to the inclined plane (F_perpendicular) = mg * cosθ

Since the inclined plane is frictionless, the force parallel to the inclined plane (F_parallel) will be canceled out by the force exerted by the spring (F_spring) when the mass reaches its highest point.

At the highest point, the gravitational force perpendicular to the inclined plane (F_perpendicular) will be equal to the force exerted by the spring (F_spring).

Therefore, we have:

F_perpendicular = F_spring

mg * cosθ = -kx

Now, let's substitute the known values and solve for k:

(5.0 kg * 9.8 m/s^2) * cos(30°) = -k * 0.20 m

49.0 N * 0.866 = -k * 0.20 m

42.426 N = -0.20 k

k = -42.426 N / (-0.20 m)

k = 212.13 N/m

Now that we know the spring constant, we can calculate the maximum potential energy stored in the spring (PE_spring) when the mass reaches its highest point:

PE_spring = (1/2) * k * x^2

PE_spring = (1/2) * 212.13 N/m * (0.20 m)^2

PE_spring = 4.243 J

The maximum potential energy (PE_spring) is equal to the maximum kinetic energy (KE_max) at the highest point, which is also the energy the mass has gained from the spring.

KE_max = PE_spring = 4.243 J

Next, we can calculate the height (h) the mass reaches on the inclined plane:

KE_max = m * g * h

4.243 J = 5.0 kg * 9.8 m/s^2 * h

h = 4.243 J / (5.0 kg * 9.8 m/s^2)

h = 0.086 m

The height the mass reaches on the inclined plane is 0.086 m.

Now, we can calculate the distance traveled.

A 5.0 kg object compresses a spring by 0.20 m with a spring constant of 25 N/m. It climbs an incline, reaching a maximum height of 0.0102 m before coming back down, traveling a total distance of 0.0428 m.

Answer:

From the question we are told that

  The length of the rod is  \(L_o\)

    The  speed is  v  

     The angle made by the rod is  \(\theta\)

Generally the x-component of the rod's length is  

     \(L_x =  L_o cos (\theta )\)

Generally the length of the rod along the x-axis  as seen by the observer, is mathematically defined by the theory of  relativity as

       \(L_xo  =  L_x  \sqrt{1  - \frac{v^2}{c^2} }\)

=>     \(L_xo  =  [L_o cos (\theta )]  \sqrt{1  - \frac{v^2}{c^2} }\)

Generally the y-component of the rods length  is mathematically represented as

      \(L_y  =  L_o  sin (\theta)\)

Generally the length of the rod along the y-axis  as seen by the observer, is   also equivalent to the actual  length of the rod along the y-axis i.e \(L_y \)

    Generally the resultant length of the rod as seen by the observer is mathematically represented as

     \(L_r  =  \sqrt{ L_{xo} ^2 + L_y^2}\)

=>  \(L_r  = \sqrt{[ (L_o cos(\theta) [\sqrt{1 - \frac{v^2}{c^2} }\ \ ]^2+ L_o sin(\theta )^2)}\)

=>  \(L_r= \sqrt{ (L_o cos(\theta)^2 * [ \sqrt{1 - \frac{v^2}{c^2} } ]^2 + (L_o sin(\theta))^2}\)

=>   \(L_r  = \sqrt{(L_o cos(\theta) ^2 [1 - \frac{v^2}{c^2} ] +(L_o sin(\theta))^2}\)

=> \(L_r =  \sqrt{L_o^2 * cos^2(\theta)  [1 - \frac{v^2 }{c^2} ]+ L_o^2 * sin(\theta)^2}\)

=> \(L_r  =  \sqrt{ [cos^2\theta +sin^2\theta ]- \frac{v^2 }{c^2}cos^2 \theta }\)

=> \(L_o \sqrt{1 - \frac{v^2}{c^2 } cos^2(\theta ) }\)

Hence the length of the rod as measured by a stationary observer is

       \( L_r = L_o \sqrt{1 - \frac{v^2}{c^2 } cos^2(\theta ) }\)

   Generally the angle made is mathematically represented

\(tan(\theta) =  \frac{L_y}{L_x}\)

=>  \(tan {\theta } =  \frac{L_o sin(\theta )}{ (L_o cos(\theta ))\sqrt{ 1 -\frac{v^2}{c^2} } }\)

=> \(tan(\theta ) =  \frac{tan\theta}{\sqrt{1 - \frac{v^2}{c^2} } }\)

Explanation:

The special relativity relations allow to find the results for the questions about the measurements made by an observed at rest on the rod are:

     a) The length of the rod is: \(L = L_o \sqrt{1 - \frac{v^2}{c^2} \ cos^2\theta_o }\)  

     b) The angle with respect to the x axis is:   \(tan \theta = \frac{tan \theta_o}{\sqrt{1- \frac{v^2}{c^2} } }\)

Special relativity studies the motion of bodies with speeds close to the speed of light, with two fundamental assumptions.

If we assume that the two systems move in the x-axis, the relationship between the components of the length are:

        \(L_x = L_{ox} \ \sqrt{1- \frac{v^2}{c^2} }\)  

        \(L_y = L_o_y \\L_z = L_{oz}\)  

Where the subscript "o" is used for the fixed observed on the rod, that is, it is at rest with respect to the body, v and c are the speed of the system and light, respectively.

a) They indicate that the length of the rod is L₀ and it forms an angle θ with the horizontal.

Let's use trigonometry to find the components of the length of the rod in the system at rest, with respect to it.

         sin θ = \(\frac{L_{oy}}{L_o}\)  

         cos θ = \(\frac{L_{ox}}{L_o}\)  

         \(L_{oy}\) = L₀ sin θ

         L₀ₓ = L₀ cos θ

Let us use the transformation relations of the length of the special relativity rod.

x-axis

      \(L_x = (L_o cos \theta_o) \ \sqrt{1- \frac{v^2}{c^2} }\)  

y-axis  

      \(L_y = L_{o} sin \theta_o\)  

The length of the rod with respect to the observer using the Pythagorean theorem is:

      L² = \(L_x^2 + L_y^2\)  

      \(L^2 = (L_o cos \theta_o\sqrt{1- \frac{v^2}{c^2} })^2 + (L_o sin \theta_o)^2\)

      \(L_2 = L_o^2 ( cos^2 \theta_o - cos^2 \theta_o \frac{v^2}{c^2} + sin^2\theta_o)\)  

      \(L^2 = L_o^2 ( 1 - \frac{v^2}{c^2} \ cos^2 \theta_o)\)  

      \(L= Lo \sqrt{1- \frac{v^2}{c^2} cos^2 \theta_o}\)  

b) the angle with the x-axis measured by the stationary observer is:

     \(tna \theta = \frac{L_y}{L_x}\)

    \(tan \ theta = \frac{L_o sin \theta_o}{L_o cos \theta_o \sqrt{1- \frac{v^2}{c^2} } }\)  

    \(tan \theta = \frac{tan \theta_o}{\sqrt{1-\frac{v^2}{c^2} } }\)  

In conclusion, using the special relativity relations we can find the results for the questions about the measurements made by an observed at rest on the rod are:

      a) The length of the rod is:  \(L = L_o \sqrt{1- \frac{v^2}{c^2} \ cos^2\theta_o }\)

      b) The angle to the x axis is:  \(tan \theta = \frac{tan \theta_o}{\sqrt{1- \frac{v^2}{c^2} } }\)

Answer:

A mass of 10 kilograms lifted 10 meters in 5 seconds.

Explanation:

Power can be defined as the energy required to do work per unit time.

Mathematically, it is given by the formula;

\( Power = \frac {Energy}{time} \)

But Energy = mgh

Substituting into the equation, we have

\( Power = \frac {mgh}{time} \)

Given the following data;

Mass = 10kg

Height = 10m

Time = 5 seconds

We know that acceleration due to gravity is equal to 9.8 m/s²

\( Power = \frac {10*9.8*10}{5} = 490 Watts \)

Hence, a mass of 10 kilograms lifted 10 meters in 5 seconds would produce the most power.
