vova2212 [387]

Answer:

f=1.57\times 10^9\ Hz

Explanation:

Given that,

A system can detect objects as small as 19.1 cm i.e. 0.191 m. It is the wavelength.

We know that,

Frequency, f=\dfrac{c}{\lambda}

So,

f=\dfrac{3\times 10^8}{0.191}\\\\=1.57\times 10^9\ Hz

So, the frequency of such a system is equal to1.57\times 10^9\ Hz.

Newton’s law of universal gravitation stars that every object in the universe attracts every other object
LenaWriter [7]

Yes it does !  Uh huh. Right you are. Truer words are seldom written.

You have quoted the law quite accurately but also incompletely.  

Do you have a question to ask ?

A crane lifts up two boxes.<br><br> Which free body diagram shows the forces acting on block A?
Temka [501]

Answer:

The 3rd graph

Explanation:

A free body diagram is a diagram which shows all the forces acting on an object.

The problem asks us to find the free body diagram of block A, so we must find all the forces acting on block A.

We have 3 forces acting on block A in total:

- The force of gravity (its weight), which pushes the block downward (in the diagram, it is the force represented with F_{gA}

- The tension in the rope 1, which pulls block A upwards: this force is represented with F_{T1}

- The tension in the rope 2, due to the weight of block 2, which pulls block A downwards: this force is represented with F_{T2}

Based on the direction of these 3 forces, the correct diagram is the 3rd one.
