If something being dropped has a mass of 0.4 kg, and the height from the floor to the top is 15 m then 20J would be the change in PE.
What is PE's formula?The force acting on the two objects affects the potential energy formula. The formula for gravitational force is P.E. = mgh, where g is the acceleration caused by gravity (9.8 m/s2 at the earth's surface) and h is the height in meters.
How much potential energy is there?Potential energy is a form of stored energy that is dependent on the relationship between different system components. When a spring is compressed or stretched, its potential energy increases. If a steel ball is raised above the ground as opposed to falling to the ground, it has more potential energy.
Given :
Mass of the object M=0.4 kg
Height up to which it is raised h=5 m
Potential energy P.E=Mgh
g = 10 m/s^2
P.E= 0.4×10×5=20J

P.E. = mgh, where g is the acceleration brought on by gravity, h is the height in metres, is the formula for gravitational force.
What is the amount of potential energy?Potential energy is a type of stored energy that depends on how various system elements interact with one another. A spring's potential energy rises when it is crushed or stretched. A steel ball has higher potential energy if it is lifted above the ground as opposed to falling to the ground.

There is a scale with a basket on it. A brick, brick #1 is placed on the scale. The brick has a mass of 10 kg. What are the two forces acting on the brick?
Answer:
Weight and reaction.
Explanation:
With respect to Newton's third law of motion, action and reaction have equal magnitude but acts in opposite direction.
Thus, the brick of mass 10 kg has its weight (due to gravitational pull of the earth), which acts downwards through its center of mass. This makes the scale to produce an opposing force of equal magnitude, which acts upwards. These two forces acting in opposite directions balancing each other.
The two forces acting on the brick are: its weight and the reaction from the scale.

is the number of paper clips in step 2 the same as the number of paper clips in step 3? why do/don't you think so?
The number of paper clips in step 2 is the same as the number of paper clips in step 3 is a true statement, as the mass is the same for both.
What is mass?It is possible to define every mechanical quantity in terms of mass, length, and time. The SI unit for mass, denoted by the letter m, is the kilogram. While mass is typically thought of as an immutable feature of an item, relativistic mass must be taken into account when traveling at speeds close to the speed of light.
Given:
The mas of the paper clips are the same,
Assume the number of clips in step two is x and the mass is m, the mass in the third step is the same as in step 2,
Thus, the number of clips = Total mass of paper clip / mass of one clip,
The number of clips = m / x
As we can see, if the mass is equal, then the number of clips will also be equal.

Mass of car = 1000kg
Acceleration due to gravity = 9.8m/s²
To find the weight of the car;
Weight is given by the formula;
Weight = mass * acceleration due to gravity
Substituting into the equation, we have;
Weight = 1000*9.8

What is the volume of the water in the graduated cylinder gizmo Student Volume Lab Sheet (cm3 and mL)
Answer:
The volume of water in the graduated cylinder will be equal to the calculated volume of the sphere.
Explanation:
The volume of solid objects can be measured by completely immersing these solids in an overflow faucet filled to brim with a liquid in which the solid does not dissolve. This is known as the displacement method. When water is used, it is known as water displacement method.
In the Volume Lab Sheet, a sphere whose volume has been pre-calculated is immersed in the overflow faucet containing water. The displaced water is collected in a beaker and the volume is obtained using a 50 mL measuring cylinder.
The volume of a sphere is calculated using the following formula:
Vsphere = 4πr³/ 3
The symbol π represents the number pi, which is about 3.14. The letter r stands for the radius of the sphere, which is the distance from the center of a sphere to its surface. The radius is exactly half of the diameter, which is the distance across the sphere through its center.
The volume of the water in the measuring cylinder is found to be equal to the calculated volume of the sphere. This is because an object immersed completely in a liquid displaces a volume of liquid equal to its own volume.

Which of the scientist responsible for cell theory would be the most likely to write a book titled Cells Come from Cells
Answer:
Rudolf Virchow
Explanation:
popularized the cell theory in an 1855 essay entitled “Cellular Pathology.” (b) The idea that all cells originate from other cells was first published in 1852 by his contemporary and former colleague Robert Remak (1815–1865).
Explanation:
Rudolf Virchow
-Rudolf Virchow would be the most likely to write a book titled 'Cells Come From Cells' because in cell theory he added a point that 'All cells arises from pre-existing cells. ' which means that all cells come from another cells which is as similar as the title of the book

1. A stone is thrown upwards with an initial velocity of 25 m/s at angle of 30° to the ground a. Show that the vertical component if the velocity at the starting is 12.5 m/s upwards.
The vertical component of the velocity at the starting is 12.5 m/s upwards.
What is velocity?Velocity is the direction at which an object is moving and serves as a measure of the rate at which its position is changing as seen from a specific point of view and as measured by a specific unit of time.
In kinematics, the area of classical mechanics that deals with the motion of bodies, velocity is a fundamental idea.
Given that stone is thrown upwards with an initial velocity of 25 m/s at angle of 30°.
Hence, the vertical component of the velocity in upward direction = 25 sin30° m/s
= 25 × 1/2 m/s
= 12.5 m/s.
