Answer: 20kg
Explanation: the above question is base on workdone...
Note: work done is also equal to potential energy.
➡Mathematical expression for the above statement:
W = P.E. where w and p.e are noted to be work done and potential energy...
Therefore; P.E = mgh
Where m is the mass of the object, g is the acceleration due to gravity and finally h is the height...
Therefore; P.E = mgh
600 = m x 10 x 3
600 = 30m
Divide both side by the coefficient of m
Therefore; 600/30 = m
m = 20kg
Answer:
mass = 20.408 kg
Explanation:
Formula: GPE = mgh
Solve:
600 = m*9.8*3
600 = m*29.4
m= 600/29.4
m= 20.408 kg
Result:
20.408 kg

A moving ball hits a stationary ball. The moving ball stops, and the stationary ball starts moving. In terms of force, what’s happening during this event?
Force is transferred from the moving ball to the stationary ball.
The stationary ball exerts a force on the moving ball.
The moving ball exerts a force on the stationary ball.
The moving ball runs out of force when it hits the stationary ball.
If a professional football player ran at you and collided with you, what would happen? Why? Use the terms force, mass, and velocity in your explanation.
Answer:
the force of the football player would cause you to fall over and possibly get a concussion because the football players mass is probably more than yours and the velocity of the football player would cause you to fall over or in football terms "get tackled"
Explanation:
Explanation:
Newton stated within his first law of motion that any object of mass at rest (velocity, designated as v, is zero) will tend to stay at rest, and any object in motion (velocity is not zero) will tend to stay in motion at the same speed and direction (acceleration, designated as a, is zero), unless acted upon by a force. Applied to football collisions, the more massive a football player (the more he weighs), the less likely he is to be slowed down, sped up, or diverted by an outside force, such as opponents. The first law is often called the law of inertia because the term inertia means the resistance to motion. For instance, the quarterback who desires to score a touchdown when very near to the goal line will often use the quarterback-sneak. In this scenario, the interior offensive line of players is used as a massive wall to block the defensive line so the quarterback can sneak around or over his men who are very resistant to being moved back.
Friction as a contact force or a noncontact force. Explain.
Answer:
Contact
Explanation:
This is because you need contact to create friction

What happens to the compass needle as you move the compass around?
A.The compass needle always points north
B.The compass needle points in random directions.
C.The compass needle follows the pattern of magnetic field lines
D.THE compass needle's north pole always points to the north pole of the magnet
When the compass needle as you move the compass around, Then the compass needle follows the pattern of magnetic field lines. The correct option is C.
What is the pattern of magnetic field lines?
Magnetic field lines are imaginary lines used to represent the direction and strength of the magnetic field around a magnet or a current-carrying wire. The pattern of magnetic field lines depends on the shape and orientation of the magnet or the wire, as well as the direction and strength of the magnetic field.
The magnetic field lines around a magnet emerge from the north pole and loop back into the south pole in a continuous path. They are always closed loops, meaning they do not begin or end anywhere but instead form a continuous path around the magnet. The magnetic field lines are closer together near the poles of the magnet, indicating a stronger magnetic field in those regions. They become less dense as they move further away from the poles, indicating a weaker magnetic field in those regions.
Here in the question,
When a compass is moved around, the compass needle aligns itself with the direction of the magnetic field lines in the vicinity. Magnetic field lines are the paths that a small compass would follow if it were placed at various points around a magnet. They indicate the direction of the magnetic field at each point.
The compass needle has a north-seeking pole and a south-seeking pole. The north-seeking pole of the compass needle aligns itself with the direction of the magnetic field lines, which are oriented from the north pole of a magnet to the south pole. This means that the north-seeking pole of the compass needle will point towards the south pole of a magnet, while the south-seeking pole of the compass needle will point towards the north pole of the magnet.
Therefore, as the compass is moved around a magnet or any other magnetic field, the compass needle will follow the pattern of the magnetic field lines, and the north-seeking pole of the compass needle will always point towards the south pole of the magnet or the magnetic field source.

A certain severe storm causes much property damage from heavy rain and winds that travel in a straight line. What type of severe storm has these characteristics? Why don’t the other types of storms apply to this description?
Answer:
A thunderstorm is a type of severe storm that is accompanied by heavy rains and straight-line winds. Since their winds travel in a single direction, it is a strong threat to lives and property.
Other storms don't apply bc they're severe.

which two statements describe how soil horizons are formed
Answer:
which two statements describe how soil horizons are formed?
Explanation:
A soil horizon is a layer parallel to the soil surface whose physical, chemical and biological characteristics differ from the layers above and beneath. Horizons are defined in many cases by obvious physical features, mainly colour and texture.
Answer:
Explanation:
As soils develop over time, layers (or horizons) form a soil profile. Most soil profiles cover the earth as 2 main layers— topsoil and subsoil. Soil horizons are the layers in the soil as you move down the soil profile. A soil profile may have soil horizons that are easy or difficult to distinguish.
