Answer: The particles can slide past one another.
Explanation : 'The heat energy moves through the material as the particles tin the material move through the material' .
It increases.
It remains unchanged.
It fluctuates up and down.
Answer: Increases the frequency of the wave
Explanation:
Increasing the tension of a spring means increasing its stiffness. The wave produced thereafter has greater frequency.
Higher tension causes the spring to have greater restoring force causing it to quickly come back to its equilibrium position. Thus, the speed of the wave also increases.
Answer:
30 km/h
Explanation:
Answer:
a = 2 m/s²
Explanation:
Given: 20 g, 40N
To find: Acceleration (a)
Solution: To find the acceleration (A), divide the force by the weight
A = F ÷ m
= 40 ÷ 20
= 2 m/s²
Newtons are derived units, equal to 1 kg-m/s². In other words, a single Newton is equal to the force needed to accelerate one kilogram one meter per second squared.
scalar
diagonal
vector
A quantity that has magnitude only is a scalar. In Physics, a quantity with only magnitude is called a scalar. Scalar quantities include distance, speed, mass, temperature, and energy. They are distinguished from vectors which have both magnitude and direction.
A scalar is a fundamental concept in mathematics and physics, representing a single quantity with magnitude but no direction. Scalars are characterized solely by their numerical value, such as speed or temperature. Unlike vectors, which have both magnitude and direction, scalars are concerned with the "how much" rather than the "where" or "in which direction." Scalars are used in various fields, from physics to mathematics and engineering, simplifying the description of quantities that don't involve direction, making calculations and analysis more straightforward.
A quantity that has magnitude only is referred to as a scalar. In Physics, quantities are typically classified into two types: scalars and vectors. A scalar quantity is defined by its magnitude alone, with no direction associated with it. Examples of scalar quantities include distance, speed, mass, temperature, and energy. On the contrary, a vector has both magnitude and direction. Hence, the correct answer to your question is scalar.
