Answer 1

Answer: C

Explanation:

Velocity is displacement over change in time. It’s a vector quantity, so velocity must include direction. You’re changing the direction, but the speed stays the same, because you are still going 20 km per hr

A. Magma in the mantle is being heated by the hot core, causing it to rise toward the crust, then sink as it cools, the convection circuit pulling the tectonic plates.

B. Water in the mantle is being heated by the hot crust, which causes it to sink toward the core where it cools, the convection circuit pulling the tectonic plates.

C. Energy from the Sun heats the crust, which conducts heat into the mantle, causing the magma to warm and sink toward the core, pulling the tectonic plates.

D. Energy from the Sun heats the crust, causing it to shift and pull the tectonic plates, which uses friction to heat the magma in the mantle.

How is the 2nd law of motion different from the 1st law of motion?

(This is about Newton's laws btw)

Answers

Answer:

Newton's First Law states that an object with no net force acting on it remains at rest or moves with constant velocity in a straight line. Newton's Second Law states that the acceleration of an object is directly proportional to the net force on the object and inversely proportional to the mass of the object. His First Law of Motion states that an object in motion tends to stay in motion unless another force acts upon it. This law is sometimes confused with the principles in his second law of motion, which states the relationship among force, mass and acceleration.

Explain the factors that determine an object's kinetic energy.

Answers

Answer:

Kinetic energy is the energy of motion. An object that has motion - whether it is vertical or horizontal motion - has kinetic energy. There are many forms of kinetic energy - vibrational (the energy due to vibrational motion), rotational (the energy due to rotational motion), and translational (the energy due to motion from one location to another). To keep matters simple, we will focus upon translational kinetic energy. The amount of translational kinetic energy (from here on, the phrase kinetic energy will refer to translational kinetic energy) that an object has depends upon two variables: the mass (m) of the object and the speed (v) of the object. The following equation is used to represent the kinetic energy (KE) of an object.

KE = 0.5 • m • v2

where m = mass of object

v = speed of object

This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four. For a threefold increase in speed, the kinetic energy will increase by a factor of nine. And for a fourfold increase in speed, the kinetic energy will increase by a factor of sixteen. The kinetic energy is dependent upon the square of the speed. As it is often said, an equation is not merely a recipe for algebraic problem solving, but also a guide to thinking about the relationship between quantities.

Kinetic energy is a scalar quantity; it does not have a direction. Unlike velocity, acceleration, force, and momentum, the kinetic energy of an object is completely described by magnitude alone. Like work and potential energy, the standard metric unit of measurement for kinetic energy is the Joule. As might be implied by the above equation, 1 Joule is equivalent to 1 kg*(m/s)^2.
