What type of glass is heat resistant?

A.leaded glass
B.tinted glass
C.borosilicate glass
D.tempered glass

Answers

Answer:

D.

Explanation:

Tempered glass is the less expensive alternative, and is best for lower temperature applications. It can withstand constant temperatures of up to 470 degrees F. Tempered glass is regular glass that has been strengthened through a thermal or chemical treatment. Tempering not only strengthens the glass but also changes its breakage pattern, causing it to shatter into small pieces instead of large sharp angles, reducing the chance of injury. It is best used for applications where the fire will not be near the glass, as constant temperatures of 500 degrees or more will cause it to weaken and shatter.

4. Calculate the momentum for each scenario:
a. .02 kg mass moving at 300 m/s
b. 2 kg mass moving at 40 m/s
c. 200 kg mass moving at 4 m/s

Answers

a) Answer:

Momentum = 6 kgm/s

Explanation:

Momentum = mass × velocity

Given that,

mass = 0.02 kg velocity = 300 m/s

Therefore, momentum = (0.02 × 300)kgm/s

Momentum = 6 kgm/s

b) Answer:

Momentum =80 kgm/s

Explanation:

Momentum = mass × velocity

Given that,

mass = 2 kg velocity = 40 m/s

Therefore, momentum = (40 × 2)kgm/s

Momentum = 80 kgm/s

c) Answer:

Momentum = 800 kgm/s

Explanation:

Momentum = mass × velocity

Given that,

mass = 200 kg velocity = 4 m/s

Therefore, momentum = (200 × 4)kgm/s

Momentum =800 kgm/s

A 1500 kg car traveling at 15m/s to the south collides with a 4500 kg truck that is initially at rest at a stoplight. the car and truck stick together and move together after the collision, what is the final velocity of the two vehicles

Answers

Answer: 3.75 m/s

Explanation:

Here's what you know: The car has mass 1500 kg, and initial velocity 15.0 m/s.  The truck has mass 4500 kg and initial velocity 0 m/s.  The final mass is 6000 kg (4500 kg plus 1500 kg, because they stick together) and we are looking for the final velocity.  Using the formula p = mv, and the concept that p before equals p after, the p of the car plus p of the truck equals the p of them together. So, 1500 x 15 + 4500 x 0 = 6000 x v final.  22500 = 6000 v, and v = 3.75 m/s.  The velocity is positive, and the initial velocity of the car was positive, so the two vehicles together are traveling to the south just like the car was initially.

Two fish swimming in a river have the following equations of motion:

X 1 = - 6.4 m + (- 1.2 m/s) t

X 2 = 1.3 m + (- 2.7 m/s) t

Which fish is moving faster? ​

Answers

Answer:

The second fish, X2, is moving faster than the first fish, X1

Explanation:

The given parameters for the equation of motion of the fishes are;

X1 = -6.4 m + (-1.2 m/s)×t

X2 = 1.3 m + (-2.7 m/s)×t

The given equation are straight line equations in the slope and intercept form, where the slope is the speed and in m/s and the intercept is the starting point of swimming of the fishes

For the first fish, the intercept = -6.4 m, the slope = the  speed = -1.2 m/s

For the second fish, the intercept = 1.3 m, the slope = the  speed = -2.7 m/s

Whereby the fishes are swimming in the opposite direction of the measurement of length, we have;

The magnitude of the speed of the second fish [tex]\left | -2.7 \ m/s \right | = 2.7 \ m/s[/tex], is larger than the magnitude of the speed of the first fish [tex]\left | -1.2 \ m/s \right | = 1.2 \ m/s[/tex]

Therefore, the second fish, X2, is moving faster than the first fish, X1.

в горизонтальном положении бревно длиной 18 м можно уравновесить на подставке, отстоящей на 3 м от его толстого конца. Если же подставка находится в 6 м от толстого конца, и на тонкий конец сядет рабочий массой 60 кг, то бревно снова будет в равновесии. Определите массу бревна.

Answers

Ответ:

90кг

Пояснение:

Найдите эскиз прилагаемой схемы. Масса бревна M размещается на отметке 3 см от толстого конца, а стержень размещается на отметке 6 см от массы бревна.

Согласно принципу момента, сумма момента по часовой стрелке равна сумме момента против часовой стрелки.

Вес корпуса в более тонкой части W = мг

W = 60 × 10 = 600 Н

Момент по часовой стрелке = 600 × 9

CW момент = 5400 Нм

Момент против часовой стрелки = M × 6

Момент ACW = 6M

Уравнять оба момента

6M = 5400

М = 5400/6

М = 900Н

Масса бревна = 900/10

Масса бревна = 90кг

Which scenario does not describe an example of acceleration?

A car increases its speed while turning to the left.
A car decreases its speed while driving straight ahead.
A car maintains a constant speed while turning to the right.
A car maintains a constant speed while driving straight ahead.

Answers

Answer:

B is the right answer

Explanation:

It is decreasing.

A car maintains a constant speed while driving straight ahead.

What is acceleration?

The acceleration of an object is the rate of change of velocity with time. It is measured in meter per second square.

Velocity of the car

The car undergoes velocity when there is change in direction of the speed.

Thus, the only option that does not describe acceleration is a car maintains a constant speed while driving straight ahead.

An apple is dropped from a 260m high building. How long will it take to hit the ground in
seconds)?

Answers

Answer:

7.28 s

Explanation:

s=-260

u=0

assume a=-9.81

t=?

s=1/2at^2 + ut

-260=1/2 (-9.81) t^2 +0t

t=7.28 s

The time taken for the apple to hit the ground from the high building is 7.28s.

Given the data in the question;

Before the apple was dropped, it was initially at rest, so

Initial velocity; [tex]u = 0 m/s[/tex]Distance or height from which it was dropped from; [tex]s = 260m[/tex]

 

To find the time it will take for the apple to hit the ground

We use the Second Equation of Motion:

[tex]s = u^2 + \frac{1}{2}at^2[/tex]

Where s is the distance or height from which it was dropped, u is its initial velocity, t is time and a is the acceleration due to gravity.

We know that earth's gravitational field or acceleration due to gravity; [tex]g = 9.8m/s^2[/tex]

Since the apple is falling, it under gravity; [tex]a = g = 9.8m/s^2[/tex]

We substitute our values into the equation and find t

[tex]260m = (0m/s)^2 + (\frac{1}{2} \ *\ 9.8m/s^2\ *\ t^2 )\\\\260m = 4.9m/s^2 \ * \ t^2\\\\t^2 = \frac{260m}{4.9m/s^2}\\\\t^2 = 53.06^2\\\\t = \sqrt{53.06s^2} \\\\t = 7.28s[/tex]

Therefore, the time taken for the apple to hit the ground from the high building is 7.28s

9) a = 25 [m/s^2], t = 4 [s]

10) a = 0.0875 [m/s^2], t = 34.3 [s]

11) t = 32 [s]

Explanation:

To solve this problem we must use kinematics equations. In this way we have:

9)

a)

[tex]v_{f}^{2} = v_{i}^{2}-(2*a*x)\\[/tex]

where:

Vf = final velocity = 0

Vi = initial velocity = 100 [m/s]

a = acceleration [m/s^2]

x = distance = 200 [m]

Note: the final speed is zero, as the car stops completely when it stops. The negative sign of the equation means that the car loses speed or slows down as it stops.

0 = (100)^2 - (2*a*200)

a = 25 [m/s^2]

b)

Now using the following equation:

[tex]v_{f} =v_{i} - (a*t)[/tex]

0 = 100 - (25*t)

t = 4 [s]

10)

a)

To solve this problem we must use kinematics equations. In this way we have:

[tex]v_{f} ^{2} = v_{i} ^{2} + 2*a*(x-x_{o})[/tex]

Note:  The positive sign of the equation means that the car increases his speed.

5^2 = 2^2 + 2*a*(125 - 5)

25 - 4 = 2*a* (120)

a = 0.0875 [m/s^2]

b)

Now using the following equation:

[tex]v_{f}= v_{i}+a*t\\[/tex]

5 = 2 + 0.0875*t

3 = 0.0875*t

t = 34.3 [s]

11)

To solve this problem we must use kinematics equations. In this way we have:

[tex]v_{f} ^{2} = v_{i} ^{2} + 2*a*(x-x_{o})[/tex]

10^2 = 2^2 + 2*a*(200 - 10)

100 - 4 = 2*a* (190)

a = 0.25 [m/s^2]

Now using the following equation:

[tex]v_{f}= v_{i}+a*t\\[/tex]

10 = 2 + 0.25*t

8 = 0.25*t

t = 32 [s]
