Which statement best describes gamma radiation?(1) It has a mass of 1 and a charge of 1.
(2) It has a mass of 0 and a charge of –1.
(3) It has a mass of 0 and a charge of 0.
(4) It has a mass of 4 and a charge of +2.

Answers

Answer 1
Answer: The correct answer is option 3. The gamma radiation has no mass and no charge. This is produced from the release of pure energy from the nucleus. This is simply a stream of high frequency energy.

If the volume and moles of a container are held constant, the temperature of a gas is inversely proportional to the pressure. TRUE
FALSE

Answers

Answer:

FALSE

Explanation:

Assuming that the gas is ideal

Therefore the gas obeys the ideal gas equation

Ideal gas equation is

P × V = n × R × T

where

P is the pressure exerted by the gas

V is the volume occupied by the gas

n is the number of moles of the gas

R is the ideal gas constant

T is the temperature of the gas

Here volume of the gas will be the volume of the container

Given the volume of the container and number of moles of the gas are constant

As R will also be constant, the pressure of the gas will be directly proportional to the temperature of the gas

P ∝ T

∴ Pressure will be directly proportional to the temperature

How is 0.00025 written in scientific notation

Answers

2.5 × 10⁴ is the scientific notation for 0.00025. this is done by moving decimal to the first non zero number.

When a number is too big or too tiny to be readily stated in decimal form, or if doing so would involve writing down an exceptionally lengthy string of digits, it can be expressed using scientific notation. It is also known as standard form within the UK and scientific form, standard index form, and standard form. Scientists, mathematicians, or engineers frequently utilise this base ten notation because it may make some mathematical operations simpler. 2.5 × 10⁴ is the scientific notation for 0.00025. this is done by moving decimal to the first non zero number.

How are science and technology related?A. Technology is a branch of natural science.
B. Science is a branch of technology.
C. Advances in science may lead to advances in technology and vice versa.
D. Science and technology are not related

Answers

It's not A because technology is a branch of applied science. It's not B because again, technology is a branch of science, not the other way around. It's not D because they are related with one being a branch of another. Therefore, it has to be C because scientific advances do lead to technological advances.
C. Advances in science may lead to advances in technology and vice versa is the correct answer~
