O E. Sound energy
A. Electrical energy B. Elastic energy are the forms of potential energy.
What is potential energy?Potential energy is the energy possess by an object because due to its position relative to other objects, stresses within itself, its electric charge, or other factors.
Types of Potential energy:
Elastic potential energy - It is stored in objects that can either be stretched or compressed. The more the object is stretched or compressed, the more elastic potential energy it will have. A classic example is a stretched rubber bandElectric potential energy - Is the energy that is needed to move a charge against an electric field. We need more energy to move a charge in the electric field, but also more energy to move it through a stronger electric field.Therefore,

0.943 m.
With what velocity does it hit the ground?
The acceleration of gravity is 9.8 m/s². (Let
down be negative.
Answer in units of m/s.
part 2 of 3
Answer:
2.65m/s
Explanation:
Using the equation of motion:
v² = u²+2a∆S where
v is the final velocity
u is the initial velocity
∆S is the change in distance
a is the acceleration
Given
u = 0m/s
a = 9.8m/s²
∆S = 1.3-0.943
∆S = 0.357m
Substituting the given parameters into the formula
v² = 0²+2(9.8)(0.357)
v² = 0+6.9972
v² = 6.9972
v=√6.9972
v = 2.65m/s
Hence the velocity at which it hit the ground is 2.65m/s

Edit: I didn't realize there is a simulation for this question, so I used the simulation and got 4.45 x 10^-7, if anybody needs the answer
Answer:
4.45×10¯⁷ N
Explanation:
The following data were obtained from the question:
Mass 1 (M₁) = 600 Kg
Mass 2 (M₂) = 400 Kg
Gravitational constant (G) = 6.67×10¯¹¹ Nm²Kg¯²
Sperating distance (r) = 6 m
Force (F) =.?
The gravitational force can be obtained as follow:
F = GM₁M₂ / r²
F = 6.67×10¯¹¹ × 600 × 400 / 6²
F = 1.6008×10¯⁵ / 36
F = 4.45×10¯⁷ N
Therefore, the gravitational force is 4.45×10¯⁷ N

Which is a vector quantity?
A distance
B. time
C.mass
D.velocity
Can anyone help,please?
Answer:
D. Velocity
Explanation:
Vector, in physics, a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity's magnitude. Although a vector has magnitude and direction, it does not have position.
Speed is a scalar quantity – it is the rate of change in the distance travelled by an object, while velocity is a vector quantity – it is the speed of an object in a particular direction.
When we look at a book in the sunlight, what must happen to the light for our eyes to see the book?

Sometimes you can see light from the Sun passing through clouds and the sunbeams appear as straight lines. After light has been reflected off an object, such as a tree or a book, it still travels in straight lines, but in a new direction.

In photosynthesis, what two compounds are produced during the light-dependent reaction then used in the light-independent reaction?
A) ATP and NADPH
B) ATP and ADP
C) NADP+ and ADP
D) NADPH and NADP+
Answer:
The answer choice is: A) ATP and NADPH
Explanation:
Your question is asking the components that are created during light - dependent reaction, and then used in independent reaction. That would be shown in the photo below!
ATP and NADPH is created from light dependent then transfered and transformed into different components from the calvin cycle (light independent cycle)
Two compounds are produced during the light-dependent reaction then used in the light-independent reaction - A) ATP and NADPH
Photosynthesis is a process that takes place in the Chloroplast of plant cells. Autotrophs obtain their energy source (food) in the presence of sunlight.
The photosynthesis process occurs in two distinct stages; light-dependent reaction and light-independent reactions.
the light reactions take place in the thylakoid membranes of chloroplasts.The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesisThese molecules are the energy storage molecule ATP and the reduced electron carrier NADPH.Thus, two compounds are produced during the light-dependent reaction then used in the light-independent reaction - A) ATP and NADPH

A mass is dropped from a height h above the ground, and freely falls under the influence of gravity. Which graphs here correctly describes the displacement and velocity of the object during the time the object is falling? Consider the "up" direction to be positive.
Which graph is it?
Answer:
B
Explanation:
The only force acting on the block is gravity, so the block has a constant, negative acceleration. This means the velocity of the block is decreasing at a constant rate, so the answer is B, D, or E. Velocity is the rate of change of displacement, and answer choice B is the only one that has a displacement graph that matches that idea.
Answer: Graph B here correctly describes the displacement and velocity of the object during the time the object is falling. Option B is correct.
It is given that the mass of an object is dropped from height 'h' above the ground and "up" direction is taken to be positive.
It is required to find the graph which describes the displacement and velocity of the object during the time the object is falling.
Which graphs here correctly describes the displacement and velocity of the object during the time the object is falling?If any body falls freely towards the ground, then its acceleration is decreasing constantly with respect to time. That means velocity of an object will also be decreased as shown in graph B. Also we know that velocity is the rate of change of displacement.
As it is given in question that up direction is positive then it is also considered that downward be negative means decreasing.
Therefore, both the quantities are decreasing. So graph B correctly describes the displacement and velocity of the object during the time the object is falling.

A car is driving down the highway at a 50 m/s. Suddenly, the driver sees an accident and slams on his breaks, coming to a complete stop in 10 seconds. How far did the car travel before coming to a stop?
Given parameters:
Speed of the car = 50m/s
Time = 10s
Unknown:
Distance traveled before the car stopped = ?
We need to establish speed - time - distance relationship.
Speed is the rate of change of distance with time. It is a scalar quantity .
Mathematically;
Speed = [tex]\frac{distance}{time}[/tex]
Distance = speed x time
Input the parameters and solve;
Distance = 50 x 10 = 500m
The car traveled 500m before it stopped.
If a person pulls a cart to the right at 5N of force and another person pulls to the left with a 15N of force? What is the net force and it what direction
Answer:
The net force is 10 [N] acting to the left
Explanation:
To solve this type of problem we must make a sum of the forces acting on the cart, since the forces are vectors, we know that vectors can be added, In this way forces that go in the same direction are added and forces in opposite directions are subtracted.
FL = force to the left = - 15 [N]
FR = force to the right = 5 [N]
FT = Resultant force [N]
- 15 + 5 = FT
FT = - 10 [N]
The negative sign tells us that the force acts to the left.

Charge
Which Element the atom is
I NEED ANSWER ASAP PLZ HELP!!!
Answer:
Explanation:
To the atomic mass;
1. Atomic mass is the number of protons + neutrons;
When a new proton is added, the atomic mass increases.
When a proton is removed, the atomic mass reduces
The mass of an atom is concentrated in the nucleus where there is the proton and neutron.
2. Atomic number is the number of protons:
When a new proton is added, the atomic number increases
When a new proton is removed, the atomic number reduces
3. Charge:
An atom is neutral if the number of positive charges is the same as negative charges:
Protons = electrons
If :
Protons > electrons = +Ve charges
Protons < electrons = -Ve charges
