Explanation:
Thermal energy refers to the energy contained within a system that is responsible for its temperature. Heat is the flow of thermal energy. A whole branch of physics, thermodynamics, deals with how heat is transferred between different systems and how work is done in the process (see the 1ˢᵗ law of thermodynamics).
The faster the atoms or molecules move, the more heat or thermal energy they have. ... A hair straightener turns the electrical energy from a wall outlet into heat (thermal energy). 4. As electricity runs through the filaments in a space heater, the electrical energy is converted into heat (thermal energy).
Answer:
They will hit the ground at the same time.
Explanation:
By ignoring the opposing forces i.e. air resistant, both the heavy and light balls will fall with same acceleration due to gravity (g=9.8 m/s²) and g is independent of mass of the objects. Thus both will hit the ground at the same time.
When the Sun's rays hit Earth at greater angles, their courses are shorter; when they hit Earth at lower angles, their trajectories are longer.
<h3 /><h3>What is Solar Radiation?</h3>
A fraction of the electromagnetic energy emitted by the sun, including infrared, visible, and ultraviolet light, is known as sunlight. When the Sun is above the horizon, sunlight on Earth is seen as daylight after being dispersed and filtered by the atmosphere.
UV, visible (PAR), and infrared are the three important bands, or ranges, of the sun energy spectrum. Infrared radiation accounts for 49.4% of the light that reaches the surface of the Earth, whereas visible light accounts for 42.3% . Just over 8% of the total solar energy is made up of ultraviolet light.

rad s⁻¹
b)
rev
Explanation:
= diameter of the merry-go-round = 5.1 m
= radius of the merry-go-round = 
= 
= 2.55 m
= time period of the merry-go-round = 4.1 s
= initial angular velocity of merry-go-round
Initial angular velocity is given as
= 
= 
= 1.53 rad s⁻¹
b)
= final angular velocity of merry-go-round = 0 rad s⁻¹
= time taken to stop = 25 s
= angular displacement = ?
= Number of revolutions made before stopping
Angular displacement is given as
rad
Number of revolutions are given as
rev
Answer:
A car exerts a force on a bug as they collide and the bug exerts an equal force on the car.
Explanation:
Newton's third law of motion states that for every action there is an equal and opposite reaction.
Action-reaction force pairs make it possible for fishes to swim, birds to fly, cars to move etc,
Furthermore, take for example, While driving down the road, a firefly strikes the windshield of a car (Action) and makes a quite obvious mess in front of the face of the driver (Reaction) i.e The firefly hit the car and the car hits the firefly.
Hence, the statement which best describes an interacting force pair represented by the third law of motion is, a car exerts a force on a bug as they collide and the bug exerts an equal force on the car.
The ultimately implies that, in every interaction, there is a pair of forces acting on the two interacting objects in this case, the car and bug. The size of the force on the car equals the size of the force on the bug. These two forces are called action and reaction forces and are the subject of Newton's third law of motion.
