A density of solid 13g/cm³ at a temperature of 25°c was now heated to a temperature of 150°c find the new density of the solid ? Given linear expansivity to be 2 × 10⁻⁵ ?
Answer:
13.4225 g/cm³
Explanation:
Given that:
Linear expansivity α = 2 * 10^-5
Change in temperature dt = t2 - t1 = (150 - 25)°c = 125°c
Initial density (d1) = 13
New density d2 =?
Using the relation :
α = (d2 - d1) / d1 * dt
d2 - d1 = d1 * dt * α
d2 = d1 + d1*dt*α
d2 = d1(1 + d1*dt*α)
d2 = 13( 1 + (13*125*2*10^-5))
d2 = 13(1 + 0.0325)
d2 = 13(1.0325)
d2 = 13.4225
d2 = 13.4225 g/cm³

Write the newtons formula for the velocity of sound in air .how did Laplace correct this formula ?
Answer:
1: v = √E/ρ where E is the elasticity and ρ is the density. Newton's assumed that sound wave travel in air under isothermal condition
2: He corrected Newton's formula by assuming that, there is no heat exchange takes place as the compression and rarefaction takes place very fast. Thus, the temperature does not remain constant and the propagation of the sound wave in air is an adiabatic process.

Assume that 10 waves pass a fixed point in 5 seconds. What is the frequency of the waves in hertz?
Answer:
2 hz
Explanation:
Hertz is cps or cycles per second. 10/5= 2 cps
The frequency of the waves when 10 waves pass a fixed point in 5 seconds is 2Hz.
What is wave ?Wave is a disturbance in a medium that carries energy as well as momentum . wave is characterized by amplitude, wavelength and phase. Amplitude is the greatest distance that the particles are vibrating. especially a sound or radio wave, moves up and down. Amplitude is a measure of loudness of a sound wave. More amplitude means more loud is the sound wave.
Wavelength is the distance between two points on the wave which are in same phase.
Phase is the position of a wave at a point at time t on a waveform.
There are two types of the wave longitudinal wave and transverse wave.
Longitudinal wave : in which, vibration of the medium (particle) is parallel to propagation of the wave. Sound wave is a longitudinal wave.
Transverse wave : in which, vibration of the medium (particle) is perpendicular to propagation of the wave. Light wave is a transverse wave.
Frequency is nothing but numbers of revolution or number of cycles or number of waves in one second. its is expressed in Hertz (Hz) in SI unit.
Given,
Number waves = 10 waves
time = 5 seconds
Frequency = ?
Frequency = No of waves ÷ time
Frequency = 10 ÷ 5
Frequency = 2 Hz
Hence frequency of the wave is 2 Hz.

A baseball is thrown upward at 20m/s. At what time is the ball 10m above the point at which it was released?
Answer:
0.583 seconds
Explanation:
We are dealing with free-fall motion, which has a constant acceleration of -g, acceleration due to gravity, so we can use a constant acceleration equation to solve this problem.
List out known variables and the variable that we want to solve for:
v_0 = 20 m/sa = -9.8 m/s² Δx = 10 mt = ?Find the kinematic equation that contains all four of these variables:
Δx = v_0 t + 1/2at²Plug known values into the equation.
10 = 20 t + 1/2(-9.8)t²Distribute 1/2 inside the parentheses.
10 = 20t - 4.9t²Set the equation equal to 0 and rearrange the terms so they are in descending degree order.
0 = -4.9t² + 20t - 10Factor this equation by using the quadratic formula. You should get:
t = 3.498 s, t = 0.583 sLet's look at these numbers within the context of the problem. If the ball's speed is 20 m/s, then after 1 second, it would reach a height of 20 m.
However, we want to find the time that it would take the ball to reach a height of 10 m, which is half of 20 m. Therefore, the time to reach 10 m should be around 0.5 seconds.
t = 0.583 is the closest to 0.5 seconds, and it fits within the context of the problem. Therefore, the answer is 0.583 seconds.
convert one mean solar day into second
Answer:
86400 seconds
Explanation:
To convert a mean solar day to second :
Number of hours in a solar day = 24 hours
Number of minutes per hour = 60 minutes
Number of seconds per minute = 60 minutes
Hence, the number of seconds in a solar day is :
(Number of hours in a solar day * number of minutes in an hour * number of seconds in a minute)
(24 * 60 * 60) seconds = 86400 seconds
Hence, 1 mean solar day = 86400 seconds

A man is standing on the edge of a 20.0 m high cliff. He throws a rock horizontally with an initial velocity of 10.0 m/s. How long does it take to reach the ground? How far does the rock land from the base of the cliff?
Answer:
t = 4.08 s
R = 40.8 m
Explanation:
The question is asking us to solve for the time of flight and the range of the rock.
Let's start by finding the total time it takes for the rock to land on the ground. We can use this constant acceleration kinematic equation to solve for the displacement in the y-direction:
Δx = v_0 t + 1/2at²We have these known variables:
(v_0)_y = 0 m/sa_y = -9.8 m/s²Δx_y = -20 mAnd we are trying to solve for t (time). Therefore, we can plug these values into the equation and solve for t.
-20 = 0t + 1/2(-9.8)t² -20 = 1/2(-9.8)t²-20 = -4.9t²t = 4.08 secThe time it takes for the rock to reach the ground is 4.08 seconds.
Now we can use this time in order to solve for the displacement in the x-direction. We will be using the same equation, but this time it will be in terms of the x-direction.
List out known variables:
v_0 = 10 m/st = 4.08 sa_x = 0 m/sWe are trying to solve for:
Δx_x = ?By using the same equation, we can plug these known values into it and solve for Δx.
Δx = 10 * 4.08 + 1/2(0)(4.08)² Δx = 10 * 4.08Δx = 40.8 mThe rock lands 40.8 m from the base of the cliff.

Francine is standing on the edge of a cliff. She determines that she has 6615J of gravitational potential energy relative to the bottom of the cliff. If she has a mass of 45kg, how high is the cliff?
Answer:
h = 14.98 [m]
Explanation:
We can calculate this height using the definition of potential energy, which tells us that this energy is equal to the product of mass by gravitational acceleration by height. In this way we can find the height, by means of the following equation:
[tex]E_{pot}=m*g*h[/tex]
where:
Epot = potential energy = 6615 [J]
m = mass = 45 [kg]
g = gravity acceleration = 9.81 [m/s²]
h = elevation [m]
[tex]6615 = 45*9.81*h\\h = 14.98 [m][/tex]
A ball is launched with an initial horizontal velocity of 10.0 meters per second. It takes 500 milliseconds for the ball to reach its maximum height.
Determine the maximum horizontal distance that the ball will travel.
Calculate the initial vertical velocity of the ball.
Answer:
500ms times 2 would be when the ball reaches the max horizontal distance.
Then to find the angle, use the formula of time to reach max height t = u sin theta / g . With t being the max height time 500ms, u being 10m/s
For initial vertical velocity just use u sin theta.
The max horizontal height is "10 meters" and the initial vertical velocity is "4.9 m/s".
Given:
Horizontal velocity,
[tex]V_x = 10 \ m/s[/tex]Time,
t = 500 m/sAt max height,
[tex]V_{yf} = 0 \ m/s[/tex](a)
→ Time to flight (T) will be:
= [tex]2t[/tex]
= [tex]2\times 0.5[/tex]
= [tex]1 \ second[/tex]
→ Horizontal distance will be:
= [tex]V_x\times T[/tex]
= [tex]10\times 1[/tex]
= [tex]10 \ meters[/tex]
(b)
→ The initial vertical velocity will be:
[tex]V_{yf} = V_y +gt[/tex]
[tex]0 = V_y - 9.8\times 0.5[/tex]
[tex]V_y = 4.9 \ m/s[/tex]

A 43 kg box is being pushed and pulled by
three forces. The first force is 155 N to the
right. The second force is 227 N to the left.
The third force is 113 N to the right. What is
the acceleration of the box?
Answer:
a = - 0.209 [m/s²]
Explanation:
To solve this problem we must use Newton's second law which tells us that the sum of forces on a body is equal to the product of mass by acceleration.
∑F = m*a
We will take the positive forces to the right and the negative forces to the left.
[tex]155-277+113=43*a\\-9=43*a\\a = - 0.209[m/s^{2} ][/tex]
The negative sign means that the box accelerates in a negative direction to the left.

If a 0.16 kg 8-ball at rest is hit by the 0.17 kg cue ball that is moving at a speed of 2 m/s, what is the speed of the 8-ball if the cue ball is completely stopped after the collision?
Answer:
The speed of the 8-ball is 2.125 m/s after the collision.
Explanation:
Law Of Conservation Of Linear Momentum
The total momentum of a system of masses is conserved unless an external force is applied. The formula for the momentum of a body with mass m and velocity v is
P=mv
If we have a system of masses, then the total momentum is the sum of them all
[tex]P=m_1v_1+m_2v_2+...+m_nv_n[/tex]
If a collision occurs, the velocities change to v' and the final momentum is:
[tex]P'=m_1v'_1+m_2v'_2+...+m_nv'_n[/tex]
In a system of two masses, the law of conservation of linear momentum takes the form:
[tex]m_1v_1+m_2v_2=m_1v'_1+m_2v'_2[/tex]
The m1=0.16 Kg 8-ball is initially at rest v1=0. It is hit by an m2=0.17 Kg cue ball that was moving at v2=2 m/s.
After the collision, the cue ball remains at rest v2'=0. It's required to find the final speed v1' after the collision.
The last equation is solved for v1':
[tex]\displaystyle v'_1=\frac{m_1v_1+m_2v_2-m_2v'_2}{m_1}[/tex]
[tex]\displaystyle v'_1=\frac{0.16*0+0.17*2-0.17*0}{0.16}[/tex]
[tex]\displaystyle v'_1=\frac{0.34}{0.16}[/tex]
[tex]v'_1=2.125\ m/s[/tex]
The speed of the 8-ball is 2.125 m/s after the collision.
How does an increase in thermal energy affect the particle motion in each state of matter?
Answer:
Explanation:
A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. The particles in solids vibrate about fixed positions; even at very low temperatures. Individual particles in liquids and gases have no fixed positions and move chaotically.
