Describe two of Tesla's inventions that influenced
technology and are still in use today.

Answers

Answer 1
Answer: The remote control, and wireless transmissions
Answer 2
Answer:

Answer:

Tesla perfected alternating current (AC) technology, which now provides electricity to all homes and appliances. He developed the fluorescent lightbulb, which is energy-efficient and cost-effective. The electric motor, which he invented, now powers appliances, machines, tools, and some cars. Tesla also built a hydroelectric power plant to generate electricity from the force of water. Tesla also studied X-rays, radios, and wireless technology.

Humans can hear frequencies up to approximately 20,000 Hz, while dogs can hear frequencies up to around 60,000 Hz. What sound frequency would you expect to be emitted by a dog whistle, which can be heard by dogs but not by humans?

Answers

Answer:

Between 23,000 to 54,000 Hz

Final answer:

A dog whistle typically emits sound at frequencies above 20,000 Hz but below 60,000 Hz, which is a range humans cannot hear but dogs can.

Explanation:

The frequency of sound emitted by a dog whistle is typically above the range of human hearing, which upper limit is around 20,000 Hz. However, since dogs can hear up to about 60,000 Hz, you would expect a dog whistle to emit sound at frequencies above 20,000 Hz but below 60,000 Hz. So, a frequency anywhere within the range 20,000 Hz and 60,000Hz would be suitable for a dog whistle.

True or False.. Although the Kinetic Theory of Matter states that the particles that make up all matter are in perpetual motion, we know that this isn’t really correct because solids don’t move.

Answers

The answer is false because kinetic energy contains motion!
The answer is false because the Kinetic Theory of Matter does not involve particles that make up all matter

How does molecules move in Hot and cold air?

Answers

Answer:

In cold air, the molecules mover slower because of the colder tempature, however, in hot air they move faster this is because the molecules are being heated up. Hot = faster, cold = slower

Explanation:

Any projectile always has a constant horizontal acceleration of _______.A. 9.81 m.s^2
B. 0 m/s^2
C. -9.81 m/s^2
D. It is not constant.

Answers

Answer: B. 0 m/s^(2)

Explanation:

When we talk about projectile motion, we have to deal with parabolic motion, which has two components: vertical and horizontal.

In the case of Earth, the acceleration is due gravity, which is constant and directed downwards (vertically) and have a value of 9.8 m/s^(2).

Now, in the case of the horizontal component, the acceleration will always be zero.

This is because we are dealing with parabolic movement, the x-component of the velocity remains the same (hence, there is no acceleration), while the y-component always change because it is affected by the acceleration due gravity that acts verticaly.

Two billion people jump up in the air at the same time with an average velocity of 7.0 m/sec. If the mass of an average person is 60 kilograms and the mass of Earth is 5.98 × 1024 kilograms:
a. What is the total momentum of the two billion people?
b. What is the effect of their action on Earth?

Answers

p=m x v =60 x 7.0= 420
total momentum = 420 x 2,000,000,000=dnt have a calculator
thier effect would shake the earth and kill some organism because they jump up at the same time and they wil probably land the same time .
