The radii of two circles are 19 cm and 9 cm respectively. Find the radius of the circle which has a circumference equal to the sum of the circumferences of the two circles.​

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:

5 seats are occupied .

[tex]60 - 25 = 35 [/tex]

Total seats 60

Unoccupied 25

occupied is total minus Unoccupied

Answer:

Answer is:-

Step-by-step explanation:

TOTAL SEATS=60

SEATS EMPTY=25

SEATS OCCUPIED=?

60-25=35

ANSWER 35 SEATS ARE OCCUPIED

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.
