When an old building is to be torn down, Mr. Pham’s company removes the bricks, cleans off the mortar from the bricks, and then sells the bricks to companies that restore historic buildings. Which compound is Mr. Pham’s company most likely to use in its work?

hydrochloric acid
nitric acid
sodium hydroxide
lithium hydroxide

Answers

Answer:

hydrochloric acid

Explanation:

The compound Mr. Pham's company used is most likely hydrochloric acid.

Hydrochloric acid is a strong acid and it is applied to remove corrosion and rusts from another body.

For industrial purposes, they are used as cleansing agents.

The acid is capable of dissolving and breaking down the rust and corrosion.

A base does not have this property and would not effectively remove the corrosion.

Sodium hydroxide and lithium hydroxide are bases.

Nitric acid is not as strong as hydrochloric acid.

In the picture above, if the cue stick strikes the 0.2-kg cue ball with a force of 1.1 N, what will be the acceleration of the cue ball?

Answers

Answer:

0.55 m/s².

Explanation:

From the question given above, the following data were obtained:

Mass (m) of ball = 2 Kg

Force (F) applied = 1.1 N

Acceleration (a) =?

Force (F) is defined as the product of mass (m) and acceleration (a). Mathematically, the force (F) can be represented as:

Force (F) = mass (m) × acceleration (a)

F = ma

With the above formula, we can calculate the acceleration of the ball as follow:

Mass (m) of ball = 2 Kg

Force (F) applied = 1.1 N

Acceleration (a) =?

F = ma

1.1 = 2 × a

Divide both side by 2

a = 1.1 / 2

a = 0.55 m/s²

Therefore, the acceleration of the ball is 0.55 m/s²

When a cricket ball is thrown vertically upwards, it reaches a maximum height of 15 metres. (a) What was the initial speed of the ball ? (b) How much time is taken by the ball to reach the highest point ? (g=10 ms -2

Answers

Answer:

The velocity of the cricket ball is 17.32 m/s

Time is taken by the ball to reach the highest point = 0.8660 seconds

Explanation:

The cricket ball can be seen and treated as a projectile in this case

The maximum height attained by a projectile in motion can be calculated using the formula:

[tex]h = \frac{v^2 sin^2 \theta }{2g}[/tex]

In any projectile problem, once we know see that the object was released vertically upwards, we need to know that this means that the angle of projection is 90 degrees, and sin 90 is = 1

hence, h will be modified to become

[tex]h = \frac{v^2 }{2g}[/tex]

[tex]v = \sqrt{2gh}[/tex]

We are given that h = 15m and g = 10m/s2

[tex]v = \sqrt{2 \times 10 \times 15} = 17.32m/s[/tex]

The velocity of the cricket ball is 17.32 m/s

B. We can get the time it took to reach the highest point by dividing

time = distance/speed

Time = 15/17.32 = 0.8660 seconds

Read the following case and discuss how you would respond to the situation.
PROBLEM:

You have been assigned the position of Environmental Engineer for one of several local
robotics manufacturers whose water discharges flow into a lake in a flourishing tourist area.
Although all the robotics companies in the area are marginally profitable, they compete for
the same customers. Included in your responsibilities is the monitoring of water and air
discharges
at your plant and the periodic preparation of reports to be submitted to the Department of
Natural Resources. You have just prepared a report that indicates that the
level of pollution in the plant's water discharges slightly exceeds the legal limitations. Your
boss, the Plant Manager, says you should regard the excess as a mere
"technicality," and he asks you to "adjust" the data so that the plant appears to be in
compliance. He says that the slight excess is not going to endanger human or fish
life any more than if the plant were in compliance. On the other hand, he says, solving the
problem would require a very heavy investment in new equipment. He
explains, "We can't afford new equipment. It might even cost a few jobs. It will set us
behind our competitors. Besides the bad publicity we'd get, it might scare off
some of the tourist industry, making it worse for everybody."

Explanation:

77. Two blocks, with masses m1 = 400 g and m2 = 600 g, are connected by a string and lie on a frictionless tabletop. A force F = 3.5 N is applied to block m2. Find the acceleration of each object.

Answers

Answer:

See the answers below. And the free body diagrams attached.

Explanation:

To solve this problem, we must build a free body diagram, where we show the forces acting on a body, first for the m2 body, where the force of 3.5 [N] acts to the right. In such a way that a reaction force is presented in the opposite direction due to the string tied between both bodies, we will call this force T1.

Now using Newton's second law, which is defined as the sum of forces equal to the product of mass by acceleration, we can determine an equation as a function of T1.

∑F = m*a

[tex]3.5 -T_{1}=0.6*a_{2}[/tex]

We have an equation with two unknowns, in such a way we must perform a second free body diagram for the body with mass m1, to acquire the additional equation.

∑F =m₁*a₁

[tex]T_{1}=0.4*a_{1}[/tex]

By kinematics we know that if the string tied to Body 2 moves a distance, the part of the string at the end tied to body 1 will move the same distance. This same analysis is valid for velocities and accelerations.

This is the accelerations a1 and a2 are equal. Now equalizing both equations.

[tex]3.5-0.4*a_{1}=0.6*a_{2}\\but\\a_{1}=a_{2}\\3.5-0.4*a_{1}=0.6*a_{1}\\a_{1}=3.5[m/s^{2} ][/tex]

The acceleration of each block connected by the given string is 3.5 m/s².

The given parameters;

mass of the first block, m1 = 400 g = 0.4 kgmass of the second block, m2 = 600 g = 0.6 kgapplied force, F = 3.5 N

The net force on the blocks is calculated as follows;

[tex]\Sigma F = ma\\\\F - T = m_2a\\\\F - m_1(a -g)= m_2a\\\\g = 0 \ , \ in \ horizontal \ direction\\\\F - m_1a = m_2 a\\\\F = m_2 a + m_1 a\\\\F = a(m_1 + m_2)\\\\a = \frac{F}{m_1 + m_2} \\\\a = \frac{3.5 }{0.4 + 0.6} \\\\a = 3.5 \ m/s^2[/tex]

Thus, the acceleration of each block connected by the given string is 3.5 m/s².

How are the molecules in a gas different from molecules in other states of matter?

Answers

Answer: The molecules in gases are different from other states of matter

Explanation:

The molecules in gases are different from other states of matter because unlike, for example, a solid, they move around freely and are much more spread apart. A gas can fill up any container, but once the container is unsealed, the gasses will immedietly be let out. Gases can be compressed much more easily than a solid or a liquid.

A.mass and location of the object
B.shape and location of the object
C.location of the object and how much energy the object has
D.mass of the object and how much energy the object has

Answers

Answer/Explanation:

The weight of an object is defined as the force that is exerted due to the gravitational force.

Mathematically, it can be written as :

W = m g

Where

m is the mass of the object

g is the acceleration due to gravity

Also,  

We know that the value of g varies with respect to the location. At the equator, the value of g is less as compared to the poles.

The feature of an object that affects its weight are :

4. A 5.00-kg sled starts at rest and accelerates down a 45.0° incline. The coefficient of
kinetic friction between the mass and the incline is .185.
a) What is the value of the of the acceleration of the sled

Answers

Answer: [tex]5.64\ m/s^2[/tex]

Explanation:

Given

mass of sled m=5 kg

Elevation [tex]\theta =45^{\circ}[/tex]

[tex]\mu _k=0.185[/tex] (coefficient of kinetic friction)

Friction will oppose the motion of the sled while sled weight sin component helps it to move down the incline

[tex]W\sin\theta-F_r=ma\\where\\W=weight(mg)\\F_r=Friction(\mu_kmg\cos\theta)\\a=acceleration[/tex]

Substituting values

[tex]mg\sin \theta-\mu_kmgcos\theta=ma\\g\sin \theta-\mu_kg\cos \theta=a\\a=g(\sin 45^{\circ}-0.185\times \cos 45^{\circ})\\a=5.64\ m/s^2[/tex]
