How does an antenna receive radio wave

Physics
1 answer:
katrin2010 [14]4 years ago
4 0

Answer:

- it turns electrical signals into radio waves so they can travel sometimes thousands of kilometers around the Earth or even into space and back.

Explanation:

In transmission, a radio transmitter supplies an electric current to the antenna's terminals, and the antenna radiates the energy from the current as radio waves. I HOPE THIS HELPS:)

How much force is needed to accelerate a 1000Kg car at a rate of 3m/s2?
ikadub [295]

According to Newton (2nd law),   Force = (mass) x (acceleration)

Substitute what we know :           Force = (1,000 kg) x (3 m/s²)

Do the arithmetic:                        Force = 3,000 kg-m/s²  =  3,000 newtons

In the great shopping cart race, two students push on shopping carts. A having twice the mass of B, with the same force applied
fiasKO [112]

B. cart B

Explanation:

The acceleration of each cart is given by Newton's second law:

F=ma

a=\frac{F}{m}

where F is the force applied, a is the acceleration and m is the cart's mass.

The force F applied is the same for the two carts, however the mass of cart A (mA) is twice than the mass of cart B (mB), so we can rewrite the two accelerations:

a_A = \frac{F}{m_A}=\frac{F}{2 m_B}

a_B = \frac{F}{m_B}

we see that the acceleration of cart B is twice the acceleration of cart A, therefore cart B will move faster and will win the race.

Describe the difference between global knowledge and personal ideas.
iren2701 [21]

Answer:

Global knowledge is information that is widely accepted and been proven as the truth. It is information that may not necessarily have a source because it is common knowledge and not easily attributed to a certain source. Personal ideas are original to the author and may not be widely accepted. It is important to give credit to others by citing their work to acknowledge that this is not your own findings but rather someone else's. It is plagiarism to use someone else's work as your own without giving credit to their work. -W0lf93

hope this helps
