Answer:
hmmm, where is the image?
but still let me tell you
Explanation:
amplitude of a wave is the maximum displacement of a particle from its rest position
so the arrow should be from the middle of the wave to the top of the crest or to the bottom trough,
from the middle
okay?
hope this helps, but be sure to add the image next time
Which of the following will best transport electrons around an electrical circuit
Answer:
b is correct!!!!!!!!!!!
The best transport electrons around an electrical circuit are connected in series. Thus, the correct answer would be option (B) are connected in series.
What is alternating current (AC)?An alternating current (AC) circuits continuously switches the direction of electron flow back and forth, which can result in fluctuations in voltage and current.
On the other hand, in a direct current (DC) electrical circuit, the electrons flow in one direction, from the negative terminal of the power source to the positive terminal. This unidirectional flow of electrons provides a consistent and stable flow of electricity throughout the circuit.
Connecting components in series mean that they are connected end-to-end, and the current flowing through them is the same.
Overall, the best option to transport electrons around an electrical circuit are to connect in series.
Therefore, the correct answer would be option (B) are connected in series.

Which two statements are true for an object with a mass of 20 kilograms that
weighs 44 pounds on Earth?
O A The object's weight would be the same on the Moon
B. The object's weight would be less on the Moon
C. The object's mass would be the same on the Moon
DD. The object's mass would be less on the Moon
Answer:
I'm pretty sure its B and C
Explanation:
B bc the weight is gravitational pull x mass so when the object has same mass the weight is smaller on moon
C bc mass is the same - you can't change it
The correct answers are B and C

A 45-kg child sits on a 3.2-kg tire swing. What is the tension in the rope that hangs from a tree branch?
Answer:
472.36 N
Explanation:
The total mass with the tire and child would be 45 kg + 3.2 kg = 48.2 kg
Ft = force tension
Fg = force of gravity
Fnet=0 (because child is motionless and not accelerating)
0 = Ft - Fg
Ft = Fg
Ft = m*g
Ft = 48.2 kg * 9.8 m/s^2
Ft = 472.36 N
Hope this helps!!
A 45-kg child sits on a 3.2-kg tire swing. The tension of the rope is 472.36 N.
The parameters given in the question is
Mass of the child= 45 kg
Mass of the tire swing attached to the tree= 3.2 kg
What is Tension?Tension can be defined as the force that can gets transmitted through a rope, string or wire when they are pulled through any forces that should acting from opposite sides.The tension force can be directed throughout the length of the wire and also it pulls the energy equally on the bodies at the ends.All the physical object which will be in contact exerts some force on one another.The first step is to calculate the total mass. The total mass can be calculated as follows;
= Mass of the child + mass of the tire swing
= 45 + 3.2
= 48.2 kg
The tension can be calculated as follows,
= mass × acceleration
= 48.2 × 9.8
= 472.36
Hence, A 45-kg child sits on a 3.2-kg tire swing. The tension of the rope is 472.36 N.

How do longitudinal waves differ from transverse waves? Give examples of both.
Answer:
Explanation:
Longitudinal
The medium moves in the same direction of the wave
It acts in one dimension
The wave cannot be polarized or aligned
This wave can be produced in any medium such as gas, liquid or solid
The earthquake P wave is an example
It is made of rarefactions and compressions
Transverse
The medium is moving perpendicular to the direction of wave
It acts in two dimension
The wave can be polarized or aligned
This wave can be produced in solid and liquid’s surface
Earthquake S wave is an example
It is made of troughs and crests
The cooling system of an automobile motor contains 20.0 kg of water. What is the Δt of the water if the engine operates until 836,000 J of heat have been added to the water?
Answer: 10 c
Explanation:
The cooling system of an automobile motor contains 20 kg of water, then the temperature change of the water is 10 °C.
What is heat?Heat is the result of the movement of kinetic energy from one substance or item to another, or from an energy source to a substance or object. Radiation, conduction, and convection are three different ways that this energy can be transferred.
The calorie (cal), the primary unit of heat in the International System of Units (SI), is the quantity of energy transfer necessary to raise the temperature of one gram of liquid from water by one degree's Centigrade, provided that the water's temperature is both higher than the freezing point and lesser than the boiling point.
The given data in the question is,
Heat, Q = 836000 J
Volume, V = 20 L
Mass, m = 20 kg
ΔT = Q/m[tex]C_p[/tex]
ΔT = (836000)/(20 × 4180)
ΔT = 10 °C
Therefore, the change in temperature will be equal to 10 °C.

1. A plane mirror has a
surface
Answer:
A plane mirror is a mirror with a flat (planar) reflective surface. For light rays striking a plane mirror, the angle of reflection equals the angle of incidence. The angle of the incidence is the angle between the incident ray and the surface normal (an imaginary line perpendicular to the surface).
