Answer:
False
Explanation:
Balanced forces result in a net force of 0N. This means no direction or acceleration change will be applied to the object. A torque may be applied, but with no other external forces, the object will not move.
How high does Pete lift his sledge hammer if he used a force of 25N to lift the hammer while doing 50J of work?
Answer:He lifts 2 meters
Explanation:We are trying to find the distance. The formula for distance is W/Force. 50 is our amount of work. 25N is how much force was used. Divide the work bye the force. 50/25=2M
4. The Himalayan Mountains tower as high as 8,854 m above sea level. The rate of plate motion is about 10 cm per year. Use the diagram to explain how the Himalayas formed. Predict how they might look in 10 million years.
Answer:
Forty million years ago, the continent of India, which was being carried northward by the Indo-Australian plate, collided with Asia forming the Himalayan mountain range (fold mountains). Since the initial encounter, the subcontinent of India has moved 2,000 kilometers farther north at a rate of 5 centimeters a year, sliding beneath Asia as it moves. In 10 million years India will plow into Tibet a further 180km. This is about the width of Nepal.

list both types of energy before skydiver jumps out of the plane and as the sky diver is diving.
Answer : This is an example of Kenitic and potential energy
Explanation:
kenitic: the act of moving or motion
potential: not. moving YET
he was not moving when he was on the plane and had potential energy cause he wasn't getting pulled down and kenitic energy was when he was getting pulled down from force of gravity when he was getting pulled to the ground when he was skydiving

An object's velocity is altered by a net force, and acceleration increases with net force. To accelerate to the same amount as being less massive objects, more massive objects need greater net forces.
What constitutes each of the four categories of forces?Any of the four fundamental forces—gravitational, electromagnetic, strong, & weak—that control how objects or particles interact as well as some particle decay—also known as the fundamental interaction is referred to as a fundamental force in physics. These basic forces serve as the foundation for all known natural forces.
Which are the main categories of force?Both contact forces & act at the a distance forces fall under the category of force. You employ force on a daily basis. Basically, force is push and pull. You exert force on an object when you push or pull it.

A meteor falls toward Earth's surface. Given that the acceleration due to
gravity is 9.8 m/s^2, what is the meteor's potential energy if it has a mass of 10
kg at an altitude of 400 m?
O A. 408 J
O B. 7,840,000 J
O C. 2J
O D. 39,200 J
Answer:
39,200J
Explanation:
just took the test
The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J
What is potential energy ?Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.
mass(m) = 10kg
g (acceleration due to gravity) = 9.8m/s^2
altitude(height (h)) = 400m
Meteor's Potential energy = m * g * h
= 10 * 9.8 * 400 = 39200 J
correct option will be a) 39200 J

What type of heat transfer is most important to maintaining a relatively stable
climate on Earth? Justify your answer.
The type of heat transfer that is most important to maintaining a relatively stable climate on Earth is known as solar radiation.
What is Heat transfer?Heat transfer may be characterized as the migration or transmission of heat across the border of the system due to an imbalance of difference in temperature between the system and its surroundings.
Solar radiations govern the principle and the entire process of heat transfer because it is the principle and fundamental source of heat and energy for the entire planet of the earth. These radiations initiate the process and pass down to the source artificial sources of heat transfer in physical life.
Therefore, solar radiation is a type of heat transfer that is most important to maintaining a relatively stable climate on Earth.

Answer:Gravity is the force among the options listed that has not directly changed Earth's surface.
Explanation:
Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects. On the other hand, folding, erosion, and weathering are all processes that directly contribute to shaping

1. The kinetic energy of the truck is 1959940.8 J
2. The kinetic energy of the car is 463037.04 J
1. How do i determine the kinetic energy of the truck?The kinetic energy of the 6000 Kg truck can be obtained as follow:
Mass of truck (m) = 6000 KgVelocity of truck (v) = 92 Km/h = 92 / 3.6 = 25.56 m/sKinetic energy of truck (KE) =?KE = ½mv²
KE = ½ × 6000 × 25.56²
KE = 1959940.8 J
Thus, the kinetic energy is 1959940.8 J
