Answer:

TRUE OR FALSE : ) IT'S TRUE

EXPLAIN:

Radiation

All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat. Radiant energy spreads out from its source in all directions. ... GAMMA RAYS have more energy than XRAYS, Radio waves, microwaves and ultraviolet waves all have longer wavelengths than visible light. Both X rays and gamma rays have higher frequencies than ultraviolet rays.

Voyager 2 is a space probe, launched in 1977, to study the outer planets. It will continue to travel through space for thousands of years without stopping. Which one of Newton's laws does this describe?

(I'm new to this website so Im just getting the hang of it)

Answers

1st law hope this helps

Voyager 2 is a space probe, launched in 1977, to study the outer planets, it will continue to travel through space for thousands of years without stopping, and it travels on Newton's first law of motion.

What is the significance of Newton's first law of motion?

It is of great importance as it is used to predict the behavior of objects in motion like Voyager 2 and to understand performance in sports such as skiing and skating etc., and help in improvement. It is also helpful for the development of new technologies for the space program and in the understanding of mechanical systems such as vehicles, machinery, etc.

Hence, Voyager 2 is a space probe, launched in 1977, to study the outer planets, it will continue to travel through space for thousands of years without stopping, and it travels on Newton's first law of motion.

Which answer shows a balanced nuclear equation for the alpha decay of plutonium-239

Answers

Answer: An alpha particle is a helium-4 nucleus, it contains gwo protons and two neutrons. So, alpha decay, giving off an alpha particle, does the following:

1)reduces the atomic number (number of just protons) by two. Plutonium has atomic number of 94, take two protons away and you are left with 92 which corresponds to uranium.

2) reduces the mass number (protons plus neutrons) by 4. If you start with 239 and subtract two protons and two neutrons, you are left with 235.

Three months into the lease, Scotty transferred his lease to a sports agent company for $5,000, which became the new tenant under the lease. Katerina became upset with Scotty's transferring of the lease because she thought that since she leased the property to Scotty, he should not be allowed to let anyone else lease the property.
