In a series circuit, the current is _______
at every point around the circuit. Which of the following completes the sentence?
Answer:In a series circuit, the current is equal at every point around the circuit.
#CARRYONLEARNING #STUDYWELLAnswer:
The option that completes the sentence is;
Equal
Explanation:
A series circuit is a circuit arrangement whereby the components of the circuit are connected in a single chain by joining them end to end, thereby the current flows round the circuit through the singular path of the interconnected component in the circuit and therefore, the current which flows through each component as it flows round circuit, is equal at all points in the circuit.
Therefore, we have that in a series circuit, the current is equal at every point around the circuit.

Answer:
A river delta is a landform created by deposition of sediment that is carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or another river that cannot carry away the supplied sediment.

1. If an object starts at 0 m/s and 0.0001 seconds later the object is travelling at
400 m/s what is the objects acceleration?
Answer:
4 x 10⁶m/s²
Explanation:
Given parameters:
Initial velocity = 0m/s
Time = 0.0001s
Final velocity = 400m/s
Unknown:
Acceleration of the object = ?
Solution:
Acceleration is the rate of change of velocity with time;
Acceleration = [tex]\frac{Final velocity - Initial velocity }{Time }[/tex]
Acceleration = [tex]\frac{400 - 0}{0.0001}[/tex] = 4 x 10⁶m/s²

How would a speed vs. time line graph appear if an airplane moved at a
positive acceleration?
Answer:
Explanation:
Acceleration is the time rate of change, or the rate, of the velocity. Therefore, the slope y/x of a speed vs time graph would give the acceleration. If the acceleration is said to be positive, the graph would be a straight line that is at a constant increase over time.

Which waves can travel through space?
electromagnetic waves only
mechanical waves only
electromagnetic and mechanical waves
longitudinal and electromagnetic waves
Answer:
Electromagnetic waves only
Only electromagnetic waves can travel through space. hence option A is correct.
What is Electromagnetic waves ?Electromagnetic waves are the waves associated with photon. Photons carry electromagnetic waves. it has both electric field and magnetic field perpendicular to each other.
when input of the Dipole antenna is connected to the electric signals having certain frequency. on first half cycle one pole is on positive potential and other is on negative potential. The pole which is at negative potential attracts all the electrons towards it and the pole which is at positive potential attracts positive holes. In the second half cycle polarity of the poles changes and it happen repeatedly, Due to change in polarity of the dipole of the antenna, electrons in the antenna produces electromagnetic waves which we use it for our radio station and mobile phones.
Electromagnetic waves does not require any medium to travel, it can travel through space(vacuum). Waves travels in the medium but there is no medium in the space, but electromagnetic waves are able to travel in the vacuum so scientist named the space as medium of ether.
Hence option A is correct.

Object V will require the most force to move because it has the smallest mass.
Earth's rotation causes winds to veer to the west or to the east. This is known as the Coriolis effect.
Lesson 1.06
Question 5 options:
True
False
Earth's rotation and spherical shape cause winds to veer to the right (in the northern Hemisphere) or to the left (in the southern Hemisphere) of the direction they want to go. This is known as the Coriolis effect.
If you didn't know that you're on a rotating Earth, and you looked at the patterns of the winds, you'd think there's some kind of force that's making the airflow veer to the right or left of the direction it actually wants to go. This is known as the Coriolis force. It's a"pseudo force", because it doesn't really exist. It only LOOKS like it's there, because of the Earth's rotation and spherical shape..
The statement "Earth's rotation causes winds to veer to the west or to the east" is true about the Coriolis effect.
What is the Coriolis effect?Fluid materials such as wind and ocean currents take different directions depending on the hemisphere, this movement of deviation is called the Coriolis effect.
Characteristics of the Coriolis effectThe Coriolis effect occurs when masses of air or water move along terrestrial meridians, and their trajectory and speed are modified by it.The winds or ocean currents that move along a meridian are diverted by accelerating in the direction of rotation (east) if they go towards the poles or the opposite (west) if they go towards the equator.Therefore, we can conclude that the force that tends to deflect the trajectory of objects moving across the entire earth's surface is known as the Coriolis effect.

. A hydraulic lift consists of two cylindrical pistons, one with a radius of 1.5 m and
the other with a radius of 8.0 cm. What force must be applied to the smaller piston if
a crate with a mass of 1.5x103 kg is to be raised on the larger piston?
F=42N,
Answer:
The force that must be applied to the smaller piston if the crate is to be raised by the larger piston is approximately 42 N
Explanation:
The given parameters of the hydraulic lift are;
The diameter of one of the pistons = 1.5 m
The diameter of the other pistons = 8.0 cm = 0.08 m
The mass of the crate to be lifted with the larger piston, m = 1.5 × 10³ kg
The weight of the mass to be lifted by the larger piston, W₁ = m × g
Where;
g = The acceleration due to gravity = 9.8 m/s²
Therefore;
W₁ = 1.5 × 10³ kg × 9.8 m/s² = 14,700 N
The area of the surface of the circular piston, A = π × r²
Where;
r = The piston's radius
∴ The area of the larger piston with 1.5 m radius, A₁ = π × (1.5 m)² = 7.06868347058 m² ≈ 7.07 m²
A₁ ≈ 7.07 m²
The area of the smaller piston with 0.08 m (8 cm) radius, A₂ = π × (0.08 m)² = 02010619298 m² ≈ 0.02 m²
A₂ ≈ 0.02 m²
The pressure in the fluid of the hydraulic lift is constant, therefore, we have;
The pressure applied to the larger piston with 1.5 m radius, P₁ = The pressure applied to the smaller piston with 0.08 m radius, P₂
∴ P₁ = P₂
[tex]Pressure = \dfrac{Force}{Area}[/tex]
[tex]P_1 = \dfrac{W_1}{A_1} = \ P_2 = \dfrac{F_2}{A_2}[/tex]
[tex]\therefore \dfrac{W_1}{A_1} = \ \dfrac{F_2}{A_2}[/tex]
Where, F₂, represents the force that must be applied to the smaller piston if the crate is to be raised by the larger piston;
[tex]\therefore F_2 = A_2 \times \dfrac{W_1}{A_1}[/tex]
Given that we have the ratio of two areas which have π as a factor, we have;
[tex]\therefore F_2 = A_2 \times \dfrac{W_1}{A_1} = 0.08^2 \times \pi \times \dfrac{14,700}{1.5^2 \times \pi } = 41.81 \overline 3[/tex]
The force that must be applied to the smaller piston if the crate is to be raised by the larger piston, F₂ = 41.81[tex]\overline 3[/tex] N ≈ 42 N.
Is gravitational energy a form of kinetic energy or potential energy? Why do you think that?
Please help due today!!
Answer:
When something is lifted, work is done on the object against the pull of gravity. This work is converted to a form of potential energy called gravitational potential energy. When the item falls towards Earth like an apple from a tree, gravitational potential energy is converted into kinetic energy.

A balloon has a volume of 25.0 L at a pressure of 98.7 kPa. Will the new volume be more or less that 25.0 L whe
the pressure is 51.2 kPa?
Answer:
It will be more
Explanation:
Pressure and volume relationships between gases is given by the Boyle's law.
According to this law, we know that:
"the volume of a fixed mass of a gas varies inversely as the pressure changes if the the temperature is constant".
So, the higher the pressure on a body, the lower it's volume and vice versa.
Since we set off at a higher pressure and wants to end at a lower pressure, the volume of the gas will increase more.
What is the independent variable?
Diameter
Circumference
Answer:
Diameter
Explanation:
I know that circumference is dependent, so diameter has to be independent
The circumference is dependent, so diameter has to be independent.
What are independent variables?Even though everything can be almost always related to its reason, when we talk about two related things, there might happen that one of those things is dependent on other.
If a variable is taking its values independently of any visible direct cause, then that variable is called independent variable.
Diameter is the line from one point in the circle to the other point through the center of the circle.
The circumference of the circle that has a radius of r is the product of diameter to the pie value.
