B. The red substance is ionic,
C. The silver substance is ionic.
I D. The white substance is ionic.

Answers

Answer 1

Answer:

A & D

Explanation:

Took the test already

Answer 2

The two statements that could be true on the basis of the information given in the question are as follows:

The silver substance is metal.The white substance is ionic.

Thus, the correct options are A and D.

What are the properties of metal?

The properties of the metal are described as follows:

They are good conductors of heat and electricity.They possess high melting points and high density. They are malleable, ductile, and lustrous in nature. They are generally hard as compared to other elements.

The silver substance is metal because it is flattened into thin sheets but did not crack. This shows the property of malleability of metals. The white substance is ionic because it is cracked but did not break. It shows that ionic compounds are tough to break.

A red substance is also metal but does not express in any options.

Therefore, the correct options for this question are A and D.

Radiation is released from the nuclei that undergo a reaction.A small amount of the mass in each nucleus that undergoes a reaction is converted to energy.

Hence, option (C) and (D) are correct.

What is nuclear reaction?

A nuclear reaction is a process in nuclear physics and nuclear chemistry where two nuclei or a nucleus and an outside subatomic particle meet to create one or more new nuclides. Consequently, at least one nuclide must change throughout a nuclear reaction.

Instead of being referred to as a nuclear reaction, the process is simply referred to as a sort of nuclear scattering if a nucleus interacts with another nucleus or particle and they subsequently separate without altering the nature of any nuclide.

How far does a sound wave travel in 3 seconds if the air temperature is 30 degrees
Celsius?

a) 114.33 m
b) 1047 m
c) 1029 m
d) 116.33 m

Answers

Answer:

B

Explanation:

v=349m/s

d=vt

d=349*3

d=1047m

WHY 349??

Because, velocity of sound increases about 0.6 m/s for every 1 degree celsius rise in temp.

Velocity of sound is about 343 m/s at 20 degrees C, so 0.6*10=6 more m/s, or 349 m/s. Kinda cool how temperature alters the speed of sound!

Explanation:

From the attachement,

M.A =  Load(L)/Effort(E)

M.A = L/E...................... Equation 1

Where M.A = .Mechanical Advantage, L = Load, E = Effort.

Given: L = 500 N, E = 100 N

Substitute these values into equation 1

M.A = 500/100

M.A = 5.

The kinetic energy of a body moving at a speed of 10 m / s is equal to 1000 J. What is the body mass

Answers

Answer:

m = 20 kg

Explanation:

Given that,

The speed of a body, v = 10 m/s

Kinetic energy of the body, K = 1000 J

We need to find the mass of the body. The formula for the kinetic energy of a body is given by :

[tex]K=\dfrac{1}{2}mv^2\\\\m=\dfrac{2K}{v^2}\\\\m=\dfrac{2\times 1000}{(10)^2}\\\\m=20\ kg[/tex]

So, the mass of the body is equal to 20 kg.

As a cold air mass advances on a warm air mass, what usually comes before it?​

Answers

Answer: A cold front occurs when a cold air mass advances into a region occupied by a warm air mass. If the boundary between the cold and warm air masses doesn't move, it is called a stationary front.

Explanation: Two types of occluded front exist: the warm-type and the cold-type. They’re distinguished by the relative temperatures of the air mass ahead of the occlusion – in other words, the air mass ahead of the original warm front – and the air mass behind the cold front. If the air behind the cold front is colder than the air ahead of the occlusion, it shoves beneath that air (because it’s denser) to form a cold-type occluded front. If the air behind the cold front is warmer than the air ahead, it rides over it to form a warm-type occluded front – which appears to be the more common case. In either situation, the lighter warm air representing the air mass originally between the warm and cold fronts sits above the boundary between the two cooler air masses.

No. If you apply a force in a chair, for example, you only will be able to move the chair if you beat the static frictional force. So, with that example, we can see that is not any type of force that can produce movement. The only force that produces movement is a result force which is non-zero.

Two kids are roller skating. Amy, with a mass of 55 kg, is traveling forward at 3 m/s. Jenny, who has a mass of 40 kg, is traveling in the opposite direction at 5 m/s. They crash into each other and hold onto each other so that they move as one mass. How fast are they traveling? How would you find your answer?

Answers

Answer:

They traveling at  along the direction of 55 kg kid.

Step-by-step explanation:

Conservation of momentum-

Momentum of a system is constant if there are no external forces acting on the system.

As they crash into each other and hold onto each other so that they move as one mass and no other force is acting on them, so conservation of momentum can be applied here.

The final direction of velocity will be opposite to the assumed direction of the mass of 40 kg.

This is a conservation of momentum problem. The equation relevant here is

[tex]\[m_1v_1+m_2v_2=\left ( m_1+m_2 \right )v_f\][/tex]

where m is the mass and v is the velocity. Because Amy and Jenny move as one mass after crashing (or colliding) with each other, this is an inelastic collision. What we to find is the final velocity, [tex]v_f[/tex], of both Amy and Jenny as a single body.

[tex]v_f=\frac{m_1v_1+m_2v_2}{\left ( m_1+m_2 \right )} = \frac{(55)(3)+(40)(5)}{(55+40)} = \text{3.84 m/s}.[/tex]

A car weighs 11000 N on Earth. What is its mass?

A) 300 kg
B) 1122 kg
C) 0 kg
D) 107,800 kg

Answers

Weight is the measurement of the force of gravity, and it is mathematically defined as the mass of an object multiplied by gravitational acceleration: W = mg. On Earth, g is about 9.8 m/s². Rearranging the equation to find mass, m = W/g. Given our weight of 11000 N, the mass of the car would thus be m = 11000 N/9.8 m/s² = 1122 kg. So, the correct answer choice here would be B.
