The potential difference between the two ends of the circuit is the electric potential difference. The electric potential difference and the work will be 10V and 1.6 x 10^-18 J respectively.
What is an electric field?An electric field is an electric property that is connected with any location in space where a charge exists in any form. The electric force per unit charge is another term for an electric field.
The given data in the problem is given by;
E is the electric field = (200 N/C)
d is the distance = 5.0 cm.=0.05 m
Q is the charge of electrons= 1.602 x 10^-19 C
The formula for electric potential is given by;

How did Edwin Hubble's discovery that the Andromeda Nebula was at least 1 million light years away change scientists' view of the universe?.
After years of observation, Hubble made an extraordinary discovery. In 1923 he spotted a Cepheid variable star in what was known as the Andromeda Nebula. Using Leavitt's techniques, he was able to show that Andromeda was nearly 1 million light years away and clearly a galaxy in its own right, not a gas cloud.

Suppose you are playing pool with a friend. The white cue ball
travels 10 m/s toward the black eight-ball, which is at rest. After
they collide, the cue ball is at rest and the eight-ball is moving.
Both have a mass of 0.16 kg. How fast is the eight-ball moving?
m/s
Answer:
10 m/s
Explanation:
u of cue ball = 10 m/s
u of eight ball=0m/s
m of cue ball =0.16 kg
m of eight ball =0.16 kg
According to law of conservation of momentum
Momentum before collision = Momentum after collision
so
( m of cue ball X velocity of cue ball) + ( m of eight ball X velocity of eight ball)= (m of cue ball X velocity of cue ball after collision )+( m of eight ball X velocity of eight ball after collision)
thus
(0.16 X 10)+(.016 X 0)= (0.16 X 0)+ ( 0.16 X velocity of eight ball after collision)
1.6= 0.16 X velocity of eight ball after collision
1.6÷0.16= velocity of ball after collision
10= velocity of eight ball after collision

A relaxed spring of length 0. 13 m stands vertically on the floor; its stiffness is 1180 N/m. You release a block of mass 0. 5 kg from rest, with the bottom of the block 0. 7 m above the floor and straight above the spring. How long is the spring when the block comes momentarily to rest on the compressed spring?.
The length of spring when the block comes momentarily to rest on the compressed spring will be 0.054 m.The length of the spring by the letter x.
What is the potential energy of the spring?The energy is stored in the spring when it is stretched or compressed by some length. It is the product of mass, gravity and distance compressed or stretched. Mathrmatically it is given by;
PE=mgh
The given data in the problem is ;
m is the mass of the block is 0.5 kg height,
h is the height is released is 0.7 m
x initial length of the spring = 0.13 m.
K is the force constant of the spring = 1180 N/m.
By the law of conservation of energy,
The potential energy of the spring gets converted
[tex]\rm mgh=\frac{1}{2}KL^2 \\\\ \rm L= \sqrt{\frac{2mgh}{K} } \\\\ \rm L= \sqrt{\frac{2\times 0.5\times9.81 \times 0.7}{1180} \\\\ \\\\[/tex]
[tex]\rm L= 0.054m[/tex]
Hence the length of spring when the block comes momentarily to rest on the compressed spring will be 0.054 m

Prompt. Explain the difference between a solar eclipse and a lunar eclipse. Be sure to explain the positions of the earth moon and sun for each scenario
Answer:
Explanation:
Eclipse happens when a large object gets in the way of another object; casting its shadow over it.
Solar eclipse happens when the moon get in between the sun and earth. It blocks sun light and causes its shadow over the sun as seen from earth.
Lunar eclipse happens when the earth is in between the sun and moon. It blocks sun light from reflecting off the moon surface so there is a shadow on the moon as seen from earth.

Density of solids What is your hypothesis (or hypotheses) for this experiment?.
I formulate a hypothesis based on their observations about what occurs when both the rock and the wood are submerged in water.
What is density?Density is defined as the mass per unit volume. It is an important parameter in order to understand the fluid and its properties. Its unit is kg/m³.
The mass and density relation is given as
mass = density × volume
I study if the volume or density of items determines whether solid objects float or sink in water in this scientific inquiry I did the experiment of density, mass, and volume using a rock and a standard-shaped piece of wood.
It is critical that the chosen piece of wood is larger than the rock and that the rock be tiny enough to fit inside the measuring cylinder. I see both the rock and a chunk of wood.
Hence I formulate a hypothesis based on their observations about what occurs when both the rock and the wood are submerged in water.

A) the current in the wire has created a gravitational field with its South Pole at the top of the rod
B) the current in the wire has created a magnetic field with its South Pole at the top of the rod.
C) the current in the wire has created a magnetic field with its North Pole at the top of the rod.
D) The current in the wire has created a gravitational field with its North Pole at the top of the rod
Answer:
did you ever get the answer
The current in the wire has created a magnetic field with its north pole at the top of the rod. This is because the magnetic field influences electric currents. Thus, the correct option is C.
What is a magnetic field?A magnetic field is a vector field which describes the magnetic influence on a moving electric charge, electric current, and magnetic material. A moving charge in a magnetic field which is experienced a force perpendicular to the own velocity and to the magnetic field.
The magnetic field is also referred to as the field where magnetic forces act to shape an electrical current. The only material or body which is capable of altering an electrical current in a magnetic field is the presence of another magnetic field in the space.
Therefore, the correct option is C.

A plane mirror forms a virtual image. give reasons
Answer:
1. The reason why a plane mirror forms a virtual image is because it doesn't let the light go through it, but it reflects the light, so if you go behind the plane mirror, then you won't see the rays of light since it's not letting the rays of light go behind it.
2. The image cannot be projected onto a screen also.
3. Also, the Rays of light never meet at a focus point, so hence, this is why the plane mirror forms a virtual image.
Thanks!
Answer:
becaise the light does not actually pass through the image

Based on scientific information, the direction that heat generally flow from is: A. hot to cold.
What is heat?Heat is also known as thermal energy and it refers to a form of energy that is only transferred from an object to another due to a difference in temperature.
During the process of heat conduction, heat would only be transferred between objects that are having different levels of temperature and objects that are directly in contact with one another.
In conclusion, heat is generally transferred from a hot object to a cold object as a result of their varying temperature.

calculate the kinetic energy of a ball of mass 50g travelling of 30m/s how much work will need to be done to stop the ball
kinetic energy of the ball of mass 50 g and velocity of 300m/s is 22.5 J. The work done need to stop the ball is equivalent to its kinetic energy. Thus, 22.5 J of work done is needed.
What is kinetic energy?The kinetic energy of an object is the energy generated by virtue of its motion. It is related to its mass and velocity by the expression written below:
Ke = 1/2 m v²
Thus, kinetic energy increases with mas and velocity.
Given that, mass of the ball = 50 g = 0.05 kg
velocity of the ball = 30 m/s
then Ke = 1/2 × 0.05 kg × 30 m/s × 30 m/s = 22.5 J.
The energy of the body when it is moving is in the form of kinetic energy. This energy of the body is equivalent to the work done on the body to stope it. Therefore, work done on the ball needed to stop it is 22.5 J.
