Answer:

Four times traveling 40,12345 mts

Explanation:

We can express this as a sum as follows

\sum_{i=1}^4(10\cdot  \frac{2}{3}^{i - 1} + 10\cdot  \frac{2}{3}^{i } ) = 3250/81=40.12345679

The first term is the dropping part and the second is the upward motion. this sums up to 40,12345 m after bouncing four times. As a program we could write using the while loop.

distance=0;

i:=0;

while distance<40 do

i:=i+1;

distance:=distance+ 10\cdot  \frac{2}{3}^{i - 1} + 10\cdot  \frac{2}{3}^{i };

end while;

Here the answer is in i and the closest distance traveled after reaching 40 is in the variable distance.

You give an object a more meaningful name by setting the object’s _________________ property.
viva [34]

Answer:

The correct answer to this question is "Name".

Explanation:

In the programming language, the object is a part of the object-oriented programming language (oops).In all (oops) programming language we use class and object. where class is a collection of data member and member function, and object is a real-world entity. An Object is an instance of a Class. When a class is created, no memory is assigned but when we create the object of the class then memory is allocated.

In this question except option (d), all options are wrong.

Recall that the Counter class initializes itself to 0 and allows a client to increment it, and the Increase class is initialized
artcher [175]

Answer:

Output can be 0 or 1 or 2.

Explanation:

As we are initializing the value with 2 so at most it will increment to 2 times means value will be 2.

when main thread is printing the c , Increase thread might be started or might not be started

so output can be 0 or 1 or 2

Select the correct statement(s) regarding the signal-to-noise ratio (SNR).
Margarita [4]

Answer:

B. the noise (i.e., noise floor) in the signal-to-noise ratio, is a wideband noise product that is predominated by thermal noise.

Explanation:

Sound can be defined as mechanical waves that are highly dependent on matter for their propagation and transmission. Sound travels faster through solids than it does through either liquids or gases.

Signal-to-noise ratio (SNR) is simply the ratio of signal power to noise power or the ratio of desired information to the undesired signal. SNR doesn't have a unit i.e it is a unitless quantity.

Generally, the higher the signal-to-noise ratio (SNR), the better would be the quality of a signal.

Additionally, a negative signal-to-noise ratio (SNR) in decibel form simply means that the signal power is lesser than the noise power.

Hence, the correct statement regarding the signal-to-noise ratio (SNR) is that the noise (i.e., noise floor) in the signal-to-noise ratio, is a wideband noise product that is predominated by thermal noise.

Note: noise can be defined as an unwanted disturbance or undesired signal present in an electrical signal.
