Crickets Chirpy and Milada jump from the top of a vertical cliff. Chirpy drops downward and reaches the ground in 2.70 s, while

Vinvika [58]

Answer:

Explanation:

Given

Time taken to reach ground is $t=2.7\ s$

Malda initial velocity $u=95\ cm/s$

Let h be the height of Cliff

using $h=ut+\frac{1}{2}at^2$

where, u=initial velocity

t=time

In first case chirpy drop downward thus u=0

$h=0+\frac{1}{2}(9.8)(2.7)^2$

$h=35.72\ m$

For Milada there is horizontal velocity u=95 cm/s=0.95 m/s[/tex]

time taken to reach the ground will be same so distance traveled in this time with 0.95 m/s horizontal velocity is given by

$R=u\times t$

$R=0.95\times 2.7=2.43\ m$

A metal wire of resistance R is cut into five equal pieces that are then placed together side by side to form a new cable with a

Alina [70]

Answer:

R / 25

Explanation:

Let the initial length of the wire is L and its resistance is R.

Now the length is cut into 5 equal parts.

The resistance of a wire is directly proportional to the length of the wire, thus, the resistance of each portion of the wire is R/5.

Now the five pieces are connected in parallel combination, the equivalent resistance is

$\frac{1}{R_{eq}}=\frac{5}{R}+\frac{5}{R}+\frac{5}{R}+\frac{5}{R}+\frac{5}{R}$

$R_{eq}=\frac{R}{25}$

Thus, the resistance of the new cable is R / 25.

Which best describes the energy change that takes place during deposition?

alina1380 [7]

The correct answer for above statement is:

A. Heat energy is released by the substance.

Explanation:

The reverse of deposition is sublimation and therefore generally deposition is termed desublimation. One example of deposition is that the method by that, in sub-freezing air, water vapor changes on to ice while not initial changing into a liquid.It is a process of releasing energy.
