Answer:

The amount of heat required is \(H_t = 1.37 *10^{6} \ J \)

Explanation:

From the question we are told that

The mass of water is \(m_w = 20 \ ounce = 20 * 28.3495 = 5.7 *10^2 g\)

The temperature of the water before drinking is \(T_w = 3.8 ^oC\)

The temperature of the body is \(T_b = 36.6^oC\)

Generally the amount of heat required to move the water from its former temperature to the body temperature is

\(H= m_w * c_w * \Delta T\)

Here \(c_w \) is the specific heat of water with value \(c_w = 4.18 J/g^oC \)

So

\(H= 5.7 *10^2 * 4.18 * (36.6 - 3.8)\)

=> \(H= 7.8 *10^{4} \ J \)

Generally the no of mole of sweat present mass of water is

\(n = \frac{m_w}{Z_s}\)

Here \(Z_w\) is the molar mass of sweat with value

\(Z_w = 18.015 g/mol\)

=> \(n = \frac{5.7 *10^2}{18.015}\)

=> \(n = 31.6 \ moles \)

Generally the heat required to vaporize the number of moles of the sweat is mathematically represented as

\(H_v = n * L_v\)

Here \(L_v\) is the latent heat of vaporization with value \(L_v = 7 *10^{3} J/mol\)

=> \(H_v = 31.6 * 7 *10^{3} \)

=> \(H_v = 1.29 *10^{6} \ J \)

Generally the overall amount of heat energy required is

\(H_t = H + H_v\)

=> \(H_t = 7.8 *10^{4} + 1.29 *10^{6}\)

=> \(H_t = 1.37 *10^{6} \ J \)

Answer:

The frequency increases by 4 because it is inversely proportional to the wavelength.

Pressure builds under the surface of Earth, causing mountains to form.The correct answer is option D.

Uplift refers to the geological process that elevates the Earth's surface, resulting in the formation of mountains. This process is primarily driven by tectonic forces, including the movement and collision of Earth's lithospheric plates.

When two plates converge, immense pressure builds up beneath the surface, causing the crust to buckle and fold. This deformation leads to the formation of mountains, as rocks are pushed upward and displaced vertically.

As the uplift process continues over millions of years, mountains gradually take shape. Erosion and weathering play significant roles in shaping their features, but it is the initial uplift that initiates the formation of mountains.

As the Earth's surface is elevated, a wide range of landforms can emerge, including rugged peaks, deep valleys, and steep slopes.

Uplift has a profound impact on the Earth's surface and ecosystems. Mountains alter local climates, influencing precipitation patterns and creating variations in temperature and wind patterns.

Therefore, uplift plays a crucial role in shaping the Earth's surface and influencing various geological, biological, and climatic processes.

Answer:C or B

Explanation:

Gases easily compress when pressure is applied, but liquids don't. So, option A.

The attracting and repellent forces that develop between the molecules of a substance are known as intermolecular forces.

Here,

The interactions between the individual molecules of a substance are mediated by the intermolecular forces. The majority of the physical and chemical features of matter are caused by intermolecular forces.

Compared to gases, which have relatively far-apart particles, liquids exhibit higher intermolecular forces due of the near proximity of their particles. The greater the intermolecular forces get as they get closer to one another since they are electrostatic in nature.

There is no force between particles in a gas. Particles have no restrictions on their movement. The container's walls colliding with one another provide the only forces that exist. which rely on the quantity of gas (number of collisions) and the momentum of each collision respectively. The pressure is nearly consistent throughout the entire mass of the gas because the molecules are free to move.

There is no compression of liquids. Since their volume is constant, changing pressure has no effect on it.

Hence,

Gases easily compress when pressure is applied, but liquids don't. So, option A.

The y-component of the vector is approximately 14.67 meters.

To find the y-component of the vector, we need to use trigonometry. Given that the vector has a magnitude of 34 meters and an angle of 26 degrees, we can break down the vector into its x and y components.

Step 1: Identify the known values:

Magnitude of the vector (r) = 34 meters

Angle (θ) = 26 degrees

Step 2: Determine the y-component using trigonometry:

The y-component can be found using the formula:

y = r * sin(θ)

Step 3: Calculate the y-component:

Substituting the known values into the formula:

y = 34 * sin(26 degrees)

y ≈ 14.67 meters

Therefore, the y-component of the vector is approximately 14.67 meters.

Answer:

24.132 m/s

Explanation:

Note

\(U\) = Initial Velocity

\(U_x\) = Initial Horizontal Velocity

\(U_y\) = Initial Vertical Velocity

\(V\) = Final Velocity

\(V_x\) = Final Horizontal Velocity

\(V_y\) = Final Vertical Velocity

\(B\) = launch angle

\(g\) = gravity

\(t\) = time

\(U_x=U*cos(B)\)

\(U_y=U*sin(B)\)

The horizontal component of the velocity is constant throughout the flight. So \(U_x=V_x\) It can be defined as

\(V_x=U*cos(B)\)

We can use the kinematics equation

\(V=U+at\)

Gravity is acting downwards; gravity would be negative

\(V_y=U_y-gt\)

The magnitude of the velocity can be defined as

\(V=\sqrt{V_x^2+V_y^2}\)

Inserting some of the other equations gives us an equation at a given time (t).

\(V=\sqrt{(U*cos(B))^2+(U*sin(B)-gt)^2}\)

\(V=\sqrt{(UcosB)^2+(UsinB)^2+(gt)^2-2gtU*sinB\)

\(V=\sqrt{U^2+g^2*t^2-2*t*g*U*sinB}\)

\(V(t)=\sqrt{U^2+g^2t^2-2tgUsinB}\)

We are given

\(U=34.6\)

\(B=80.2\)

\(t=1.09\)

\(g=9.81\)

\(V(1.09)=\sqrt{34.6^2+9.81^2*1.09^2-2*1.09*9.81*34.6*sin80.2}\)

\(V(1.09)=\sqrt{34.6^2+114.338-2*1.09*9.81*34.6*sin80.2}\)

\(V(1.09)=\sqrt{34.6^2+114.338-739.94868*sin80.2}\)

\(V(1.09)=\sqrt{34.6^2+114.338-729.151}\)

\(V(1.09)=\sqrt{1197.16+114.338-729.151}\)

(a) The maximum height attained by the car is 21.57 m.

(b) The thermal energy generated by friction is 85,017.6 J.

(c) The average force of friction of the hill is 370.8 N.

The maximum height attained by the car is calculated by applying the principle of conservation of energy as follows;

P.E = K.E

mgh = ¹/₂mv²

h = (v²) / (2g)

where;

h = (20.56²) / (2 x 9.8)

h = 21.57 m

The thermal energy generated by friction is determined from the change in the mechanical energy of the car.

ΔE = K.E - P.E

ΔE = ¹/₂mv² - mgh

where;

ΔE = ¹/₂(750)(20.56)² - (750)(9.8)(10)

ΔE = 85,017.6 J

The average force of friction of the hill is calculated as follows;

Fd = ΔE

where;

d = h/sin(2.5) = 10 m / sin(2.5) = 229.26 m

F(229.26) = 85,017.6

F = (85,017.6) / (229.26)

F = 370.8 N

It has to do with impulse or force. Just how the sheet has no volume. There is no sufficient impulse to crack the shell.

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

The sagging sheet gives the impact with the egg additional time, which prevents the egg from breaking when it is hurled against it. This lessens the force the egg would have applied to the wall had it been flung at it.

Explanation:

Force= mass × acceleration

= 3.6 × 4.2

= 15.12N

If the mass of the box is 3.6 kg and it is accelerating with 4.2 m/s², then the force exerted on the box is 15.12 N.

The definition of force is: The push or pull on a massed object changes its velocity. An external force is an agent that has the power to alter the resting or moving condition of a body. Every time two items interact, a force is exerted on each of the objects. The force is no longer felt by the two objects when the interaction ends. Only when there is interaction do forces actually exist.

The strong force, weak force, electromagnetic force, and gravitational force are the four fundamental forces operating in the universe. The formula of force is  Force = mass × acceleration.

Hence, if the mass of the box is 3.6 kg and it is accelerating with 4.2 m/s², then the force exerted on the box is 15.12 N.

Hi there!

Recall the equation for magnetic force on a moving particle.

\(F_B = qv \times B\)

\(F_B\) = Magnetic Force (N)
q = Charge of particle (C)

v = Velocity of particle (m/s)
B = Magnetic Field Strength (T)

**This is a cross product, so the equation can be written as \(F_B\) = qvBsinφ where φ is the angle between the velocity vector and magnetic field vector.

Since the proton is traveling perpendicular to the field, we can disregard the cross product. (sin90 = 1.)

Rearrange the equation to solve for 'B':

\(B = \frac{F_B}{qv}\\\\B = \frac{1.15 * 10^{-13}}{(1.6 * 10^{-19})(3.0 * 10^6)} = \boxed{0.24 T}\)
