Answer:

x+4

where x is the last term obtained

Step-by-step explanation:

Answer:

This series is an AP because the difference between the two consecutive terms is the same. Hence, the nth term of 5,9,13,17,--- is (4n+1).

Answer:

1. Wool is a conductive material, which means it readily gives away its electrons. Consequently, when you rub a balloon on wool, this causes the electrons to move from the wool to the balloon's surface. ... When the balloon has been rubbed enough times to gain a sufficient negative charge, it will be attracted to the wall.
2. Lightning is a result of electrical charges. And lightning occurs mostly on tall objects. ... Therefore, one should not stand near a tree or a tall building during a thunderstorm because Lightning can strike trees and buildings and further it can jump to humans easily.
3. 3.charged body loses its charge if we touch it with our hand because when we touch a charged body, it loses its charge and become neutral due to the process of earthing. Our body is a good conductor of electricity. It transfers the charges to the earth.
4. Tall buildings have lightning conductors to help transport the electrical current from a lightening strike to the ground safely. This protects the structure's electrical equipment and the materials used within the building

Explanation:

Answer:

4)tall buildings have conductor

Answer:

The radius of the 1st circle = 19 cm (given)

∴ Circumference of the 1st circle = 2π×19 = 38π cm

The radius of the 2nd circle = 9 cm (given)

∴ Circumference of the 2nd circle = 2π×9 = 18π cm

So,

The sum of the circumference of two circles = 38π+18π = 56π cm

Now, let the radius of the 3rd circle = R

∴ The circumference of the 3rd circle = 2πR

It is given that sum of the circumference of two circles = circumference of the 3rd circle

Hence, 56π = 2πR

Or, R = 28 cm.

Answer:

Daniel Bernoulli was a Dutch-born member of the Swiss mathematical family. His most important work considered the basic properties of fluid flow, pressure, density and velocity, and gave the Bernoulli principle.

Explanation:

He put forward what is called Bernoulli's principle, which states that the pressure in a fluid decreases as its velocity increases.
