The equivalent temperature in Celsius scale is (86°F − 32) × 5/9 = 30°C

Take the °F temperature and subtract 32

Multiply this number by 5.

Divide this number by 9 to obtain your answer in °C.

The formula to convert °F to °C is:

T(°C) = (T(°F) - 32) × 5/9

converting 86 degrees Fahrenheit into degrees Celsius:

T(°C) = (86°F - 32) × 5/9

T(°C) = 30 °C

(86°F − 32) × 5/9 = 30°C

When doing the temperature conversion, one quick way to make certain you did the conversion right is to remember Fahrenheit temperatures are higher than the corresponding Celsius scale until you get down to -40°, which is where the Celsius and Fahrenheit scales meet. Below this temperature, degrees Fahrenheit are lower than degrees Celsius.

I hope it helps ❤❤

The type of collision experienced by the two objects is inelastic collision, because internal kinetic energy is not conserved.

There are two types of collisions that two objects moving directly or opposite each may experience:

In elastic collision, both momentum and kinetic energy of the to objects are conserved.

In inelastic collision, only momentum is conserved while kinetic energy decreases after the collision.

Thus, we can conclude that the type of collision experienced by the two objects is inelastic collision, because internal kinetic energy is not conserved.

The tension in the rope if it is parallel to the slope is 24.31 N.

Explanation:

Given;

mass of the sled, m = 9 kg

angle of inclination of the slope, θ = 16⁰

The tension in the rope if it is parallel to the slope is calculated from the parallel component of the tension;

\(T_|_| = mgSin \theta\\\\T_|_| = 9 \times 9.8 \times sin(16^0)\\\\T_|_| = 24.31 \ N\)

Therefore, the tension in the rope if it is parallel to the slope is 24.31 N.

The muzzle speed of the bullet = 360 m/s

Mass of the bullet, m = 0.025 kg

Length of the rifle, d= 0.45 m

Force on the bullet, F = 3600 N

Workdone on the bullet (W) = Force on the bullet (F) x Length of the rifle(d)

W = Fd

W = 3600 x 0.45

W = 1620 Joules

Kinetic energy of the bullet, KE = 0.5mv²

where v is the speed that the bullet leaves the gun barrel

KE = 0.5 x 0.025 x v²

KE = 0.0125v²

Workdone on the bullet = Kinetic Energy on the bullet

W = KE

1620 = 0.0125v²

v² = 1620/0.0125

v² = 129600

v = 360 m/s

The muzzle speed of the bullet = 360 m/s

The work done by gas is 0.753 J and change in internal energy is 4.247J

So we are given that mass is 2kg , radius 1 cm and the amount of heat is 5 cm

The piston raised by 2.4cm

As we know that Work done is PΔV

Where ΔV is change in volume

Therefore ΔV =  πr^2 h = π x (.01)^2 x .024 =7.53×10^(-6)m^3

Here pressure is 10^5 pa

So W = \(10^5\times7.53\times10^-(6)\)

Therefore W = 0.753 J

Now coming to change in internal energy

Change in Internal Energy = Heat Added - Energy lost in work

∴ 5J - 0.753 J = 4.247J

Hence the change in internal energy is 4.247 J

Answer:

The temperature of the steam during the heat rejection process is 42.5°C

Explanation:

Given the data in the question;

the maximum temperature T\(_H\) in the cycle is twice the minimum absolute temperature T\(_L\) in the cycle

T\(_H\)  = 0.5T\(_L\)

now, we find the efficiency of the Carnot cycle engine

η\(_{th\) = 1 - T\(_L\)/T\(_H\)

η\(_{th\) = 1 - T\(_L\)/0.5T\(_L\)

η\(_{th\) = 0.5

the efficiency of the Carnot heat engine can be expressed as;

η\(_{th\) = 1 - W\(_{net\)/Q\(_H\)

where W\(_{net\) is net work done, Q\(_H\) is is the heat supplied

we substitute

0.5 = 60 / Q\(_H\)

Q\(_H\) = 60 / 0.5

Q\(_H\) = 120 kJ

Now, we apply the first law of thermodynamics to the system

W\(_{net\) = Q\(_H\) - Q\(_L\)

60 = 120 -  Q\(_L\)

Q\(_L\) = 60 kJ

now, the amount of heat rejection per kg of steam is;

q\(_L\) = Q\(_L\)/m

we substitute

q\(_L\) = 60/0.025

q\(_L\) = 2400 kJ/kg

which means for 1 kilogram of conversion of saturated vapor to saturated liquid , it takes 2400 kJ/kg of heat ( enthalpy of vaporization)

q\(_L\) = h\(_{fg\) = 2400 kJ/kg

now, at  h\(_{fg\)  = 2400 kJ/kg from saturated water tables;

T\(_L\) = 40 + ( 45 - 40 ) ( \(\frac{2400-2406.0}{2394.0-2406.0}\\}\) )

T\(_L\) = 40 + (5) × (0.5)

T\(_L\) = 40 + 2.5

T\(_L\) = 42.5°C  

Therefore, The temperature of the steam during the heat rejection process is 42.5°C

Explanation:

(a) When m₂ is released, its acceleration will be approximately -3.27 m/s².

(b) The tension in the string is approximately -13.08 N.

To determine the acceleration of m₂ when it is released and the tension in the string, we need to consider the forces acting on the system.

(a) Acceleration of m₂:

Since the pulley is assumed to be frictionless, the tension in the string is the same on both sides of the pulley. We can consider the system consisting of m₁ and m₂ as one body. The net force acting on this system is the difference between the weight of m₁ and the weight of m₂:

Net force = m₁g - m₂g

Applying Newton's second law, F = ma, where F is the net force and a is the acceleration, we have:

m₁g - m₂g = (m₁ + m₂)a

Rearranging the equation to solve for the acceleration, we get:

a = (m₁g - m₂g) / (m₁ + m₂)

Substituting the given values, m₁ = 2.00 kg and m₂ = 4.00 kg, and the acceleration due to gravity, g = 9.8 m/s², we can calculate the acceleration:

a = ((2.00 kg)(9.8 m/s²) - (4.00 kg)(9.8 m/s²)) / (2.00 kg + 4.00 kg)

a = (19.6 N - 39.2 N) / 6.00 kg

a = -19.6 N / 6.00 kg

a = -3.27 m/s²

Therefore, when m₂ is released, its acceleration will be approximately -3.27 m/s². The negative sign indicates that the acceleration is in the opposite direction of the gravitational force.

(b) Tension in the string:

The tension in the string can be determined by considering the forces acting on m₂. The net force on m₂ is equal to its mass multiplied by its acceleration:

Net force = m₂a

Substituting the given values, m₂ = 4.00 kg and a = -3.27 m/s², we can calculate the tension:

Tension = (4.00 kg)(-3.27 m/s²)

Tension = -13.08 N

Therefore, the tension in the string is approximately -13.08 N. The negative sign indicates that the tension acts in the opposite direction of the weight of m₂.

The forklift's upward force must be equal to and opposite to the force of gravity pulling the box downward because the box must move upward at a constant speed for the net force acting on it to be zero.

Therefore, option C, which depicts the forklift's upward force (labeled as F) and gravity's downward force (labeled as mg, where m is the box's mass and g is the acceleration caused by gravity), is the free-body diagram that best reflects the forces experienced by the box. The absence of any additional arrows in the diagram indicates that the box is not subject to any other forces.

A free body diagram is a visual representation of the forces exerted on an object in a particular system or circumstance. It is a simplified drawing that shows all of the forces acting on the object of interest and separates it from its surroundings. Gravitational forces, normal forces, frictional forces, tension forces, and any other relevant forces are examples of these forces.

A free body diagram shows the object as a dot or a small box, and the forces are shown as arrows pointing in the same direction. The force's magnitude is shown by the length of the arrow, and the force's direction is shown by the arrow's direction. The force's name is written on the labels of the arrows.

Answer:

When you know both the speed and direction of an object's motion, you know the velocity of the object.

Answer:

The speed of the bullet just before the impact is 701 m/s

Explanation:

Given;

mass of the bullet, m₁ = 20 g = 0.02 kg

mass of the block, m₂ = 2.8 kg

displacement of the block, d = 9 mm = 9 x 10⁻³ m

duration of motion of the bullet, t = 5 ms = 5 x 10⁻³ s

Apply the principle of conservation of energy;

The final kinetic energy of the bullet = maximum potential energy of the block

\(\frac{1}{2} m_1v^2 = m_2gh\\\\v^2 = \frac{2m_2gh}{m_1} \\\\v= \sqrt{\frac{2m_2gh}{m_1} } \\\\v = \sqrt{\frac{2 \times 2.8 \times 9.8 \times (9\times 10^{-3})}{0.02} } \\\\v = 4.97 \ m/s\)

Apply the principle of conservation of linear momentum, to determine the initial velocity of the bullet before the impact.

m₁u₁  +  m₂u₂  =  v(m₁  +  m₂)

where;

u₁ is the initial velocity of the bullet

u₂ is the initial velocity of the block = 0

m₁u₁  +  0  = v(m₁  +  m₂)

m₁u₁  =  v(m₁  +  m₂)

0.02u₁ = 4.97(2.8 + 0.02)

0.02u₁ = 14.02

u₁ = 14.02 / 0.02

u₁ = 701 m/s

Therefore, the speed of the bullet just before the impact is 701 m/s

Answer:

Explanation:

Key point: the vertical motion is free fall, the horizontal motion remains at uniform speed of 100 m/s (because there is no force in the horizontal direction if we neglect air resistance.)

The time of free fall can be calculated first:

h = 1/2 g t^2 => t = sqrt(2 h /g) = sqrt(2 * 300 m / 9.81 s) = 7.82 seconds.

In that time, the horizontal displacement will be

s = v_horizontal * t = 100 m/s * 7.82 s = 782 m.

So the box will land 782 m further than the point it was dropped from (and 300 m lower of course)

The time taken is obtained as 6.95 s.

The time taken could be obtained from the equations of kinematics. In this case, we have to first convert the given velocities to m/s as follows;

u; 70 * 1000/3600 = 19.44 m/s

v; 110  * 1000/3600 = 30.56 m/s

Then we apply the equations of motion;

v = u + at

a =  1.6 m/s2

We now have;

v - u/a = t

t = 30.56 m/s - 19.44 m/s/ 1.6 m/s2

t = 6.95 s
