The magnitude and direction of the object's displacement is 7 m and west direction respectively.

<h3>What is displacement?</h3>

The displacement of an object is the change in the position of the object. Displacement is a vector quantity because it has both magnitude and direction.

To find the sum of the vectors, we find the displacement of the vectors.

Initial position of the vector = 10 m east

final position of the vector = 3 m west

displacement of the vector = final position - initial position

displacement of the vector = 3 m - 10 m

displacement of the vector = - 7 m

magnitude of the displacement = 7 m

direction of the displacement = west

Thus, the magnitude and direction of the object's displacement is 7 m and west direction respectively.

Softa [21]

Answer:

$1.08 * 10^{14} J$

Explanation:

Energy and mass are related by the famous equation developed by Albert Einstein:

$E = mc^2$

where m = mass and c = speed of light

This equation explains that an object with very small mass can produce a large amount of energy in reactions such as a nuclear reaction.

Hence, the energy produced by the explosion of a Plutonium bomb containing 3.6 grams of matter is:

$E = 3.6 * 10^{-3} * (3 * 10^8)^2$

E = $1.08 * 10^{14} J$

If the accuracy in measuring the position of a particle increases, the accuracy in measuring its velocity will Group of answer c

Sindrei [870]

Answer:

The correct answer is Option A (decrease).

Explanation:

According to Heisenberg's presumption of unpredictability, it's impossible to ascertain a quantum state viewpoint as well as momentum throughout tandem.
Also, unless we have accurate estimations throughout the situation, we will have a decreased consistency throughout the velocity as well as vice versa though too.

Other given choices are not connected to the given query. Thus the above is the right answer.

You know that you sound better when you sing in the shower. This has to do with the amplification of frequencies that correspond

Lera25 [3.4K]

Answer: Length axis f= 114.3 Hz, Width axis f=228.67 Hz

Explanation:

We are given that,

Length of tub= 1.5 m

Width of tub= 0.75 m

Sound speed= 343 m/s

Now, we are also given shower is closed.

So, frequency is given as:

f= $m* \frac{v}{2L}$

For length axis

Put v= 343 m/s, m=1 and L=1.5 m

f= 1 * $\frac{343}{2*1.5}$

f= 114.3 Hz

For next resonant frequency, m=2

f= 2* $\frac{343}{2*1.5}$

f= 228.67

For width axis

Put v= 343 m/s, m=1 and L= 0.75 m

f= 1* $\frac{343}{2*0.75}$

f= 228.67 Hz

For next frequency, m=2

f= 2* $\frac{343}{2*0.75}$

f= 457.34 Hz
