Which statement is true?

A. Magnetic North is geographic North
B. A compass needle points south
C. Magnetic electrons flow out North and into South
D. Earth's magnetic field reaches past the Milky Way.​​

Answers

Option - D is true

(A magnetic compass does not point to the geographic north pole. A magnetic compass points to the earth's magnetic poles, which are not the same as earth's geographic poles. Furthermore, the magnetic pole near earth's geographic north pole is actually the south magnetic pole. When it comes to magnets, opposites attract.)

Are these pictures below an example of reflection or refraction?

Answers

Refraction because the light is being altered (bending) and appearing in a different way (direction). Reflection is like a mirror

Answer:

Refraction

Explanation:

Reflection involves a change in direction of waves when they bounce off a barrier.

Refraction of waves involves a change in the direction of waves as they pass from one medium to another.

A rock is thrown upward with a speed of 2.0m/s.
a. How long will it take the rock to reach the peak?
b. What is the maximum height it can reach?

Answers

Hi there!

(A)

When the rock reaches the peak, it will have a vertical velocity of 0 m/s. We can use the equation:

vf = vi + at

vf = final velocity (0 m/s)

vi = initial velocity (2 m/s)

a = acceleration (in this situation, due to gravity = 9.8 m/s²)

t = time (s)

0 = 2 + (-9.8)t

2/9.8 = t = .204 sec

(B)

Use the equation:

d = vit + 1/2at²

d = 2(.204) + 1/2(-9.8)(.204²)

d = .204 m

A 400g ball moving toward the east at 3.7m/s suddenly collides head-on with a 200g ball sitting at rest. Determine the velocity of the first ball just after collision

Answers

The final velocity of the first ball after the collision is 1.167 m/s to the west.

The given parameters;

mass of the moving ball, m₁ = 400 g = 0.4 kgvelocity of the moving ball, u₁ = 3.7 m/smass of the ball at rest, m₂ = 200 g = 0.2 kg

Let the velocity of the first ball after collision = v₁

Let the velocity of the ball at rest after collision = v₂

Apply the principle of conservation of linear momentum;

[tex]m_1u_1 + m_2u_2 = m_1v_1 + m_2v_2\\\\0.4(3.7)+ 0.2(0) = 0.4(-v_1) + 0.2v_2\\\\1.48 = -0.4v_1 + 0.2v_2[/tex]

Apply one-directional velocity formula;

[tex]u_1 + v_1 = u_2 + v_2\\\\3.7 - v_1 = 0 + v_2\\\\v_2 = 3.7 -v_1[/tex]

substitute the value of v₂ into the above equation;

[tex]1.48 = -0.4v_1 \ + \ 0.2(3.7 -v_1)\\\\1.48 = -0.4v_1 + 0.74 - 0.2v_1\\\\0.74 = -0.6v_1\\\\v_1 = \frac{-0.74}{0.6} \\\\v_1 = -1.167 \ m/s[/tex]

[tex]v_2 = 3.7 + 1.167\\\\v_2 = 4.867 \ m/s[/tex]

Thus, the final velocity of the first ball after the collision is 1.167 m/s to the west.

Thea uses a hairdryer to dry her hair. The hairdryer has an efficiency of 0.5 and the total input energy is 180 kJ. How much of the energy supplied is wasted? Give your answer in joules

Answers

90kJ of the energy supplied to the hair dryer is wasted.

Efficiency is the ratio of output to input. It is given by:

Efficiency = output / input

Given an efficiency of 0.5 and the total input energy is 180 kJ. Hence:

Efficiency = output / input

0.5 = output / 180 kJ

Output = 90 kJ

Amount of wasted energy = Input - output = 180kJ - 90kJ = 90kJ

Therefore 90kJ of the energy supplied is wasted.

Deductive reasoning

Deductive reasoning. Deductive reasoning implies the use of a given set of facts or data to deduce other facts, by reasoning logically. It rearranges information that is already known into new statements or truths. Hence transitivity, reflexivity, and identity refer to it and are necessary elements.

What are deductive reasoning and examples?

Deductive reasoning is a type of deduction used in science and in life. It is when you take two true statements, or premises, to form a conclusion. For example, A is equal to B. B is also equal to C. Given those two statements, you can conclude A is equal to C using deductive reasoning.

Examples of mediums that waves can travel through are _______ Select ALL that apply.
A. Air
B. Water
C. Ground
D. Metal

Answers

Answer:

air and water

Explanation:

The matter through which a mechanical wave travels is called the medium (plural, media). There are three types of mechanical waves: transverse, longitudinal, and surface waves. They differ in how particles of the medium move when the energy of the wave passes through. The particles in a medium become disturbed and pass on this disturbance to the next one, and so on. So, the disturbance caused by the particles can travel through a medium such as air, ocean water, land, violin strings, Slinky coils, etc. Sound waves can travel through solids, liquids, or gases.
