Answer:

The answer is "They involve changes in energy".

Explanation:

Energy change is quite important in chemicals because nearly all reactions involve activation energy. They will learn and learn how to utilize different types of energy shifts in the steam cycle. A conversation about what drives chemical processes contributes to entropy and natural energy principles. It may shift from the shape of form. For example, chemicals might change to heat. Laser light can turn substances into power. Its energy can be changed into different kinds, but not wasted or produced.

Answer:

Transverse waves oscillate perpendicular to the direction of the wave (e.g. any electromagnetic wave like radiowaves, x-rays...) whilst compressional waves oscillate in the same direction of the wave (e.g. sound waves)

A simple pendulum consists of a 2 kg bob attached to a 1.5 m long string. How much time (in s) is required for this pendulum to
Charra [1.4K]

Answer:

6.15 s

Explanation:

The period of a simple pendulum is given by the equation

T=2\pi \sqrt{\frac{L}{g}}

where

L is the length of the pendulum

g is the acceleration of gravity

For the pendulum in this problem,

L = 1.5 m (length)

g=9.8 m/s^2 (acceleration due to gravity on Earth)

Therefore, its period is

T=2\pi \sqrt{\frac{1.5}{9.8}}=2.46 s

And therefore, the time taken for the pendulum to complete 2.5 oscillations is equal to 2.5 times the period:

t=2.5T=(2.5)(2.46)=6.15 s
