Explanation:
The given data is as follows.
Mass, m = 75 g
Velocity, v = 600 m/s
As no external force is acting on the system in the horizontal line of motion. So, the equation will be as follows.
where,
= mass of the projectile
= mass of block
v = velocity after the impact
Now, putting the given values into the above formula as follows.
![75(10^{-3}) \times 600 = [(75 \times 10^{-3}) + 50] \times v](https://tex.z-dn.net/?f=75%2810%5E%7B-3%7D%29%20%5Ctimes%20600%20%3D%20%5B%2875%20%5Ctimes%2010%5E%7B-3%7D%29%20%2B%2050%5D%20%5Ctimes%20v)
= ![\frac{45}{50.075}](https://tex.z-dn.net/?f=%5Cfrac%7B45%7D%7B50.075%7D)
v = 0.898 m/s
Now, equation for energy is as follows.
E = ![\frac{1}{2}mv^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dmv%5E%7B2%7D)
= ![\frac{1}{2} \times (75 \times 10^{-3} + 50) \times (600)^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%20%2875%20%5Ctimes%2010%5E%7B-3%7D%20%2B%2050%29%20%5Ctimes%20%28600%29%5E%7B2%7D)
= 13500 J
Now, energy after the impact will be as follows.
E' = ![\frac{1}{2}[75 \times 10^{-3} + 50](0.9)^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5B75%20%5Ctimes%2010%5E%7B-3%7D%20%2B%2050%5D%280.9%29%5E%7B2%7D)
= 20.19 J
Therefore, energy lost will be calculated as follows.
= E E'
= (13500 - 20) J
= 13480 J
And, n = ![\frac{\Delta E}{E}](https://tex.z-dn.net/?f=%5Cfrac%7B%5CDelta%20E%7D%7BE%7D)
= ![\frac{13480}{13500} \times 100](https://tex.z-dn.net/?f=%5Cfrac%7B13480%7D%7B13500%7D%20%5Ctimes%20100)
= 99.85
= 99.9%
Thus, we can conclude that percentage n of the original system energy E is 99.9%.
Density is the mass per unit volume of any object. It is calculated by dividing the mass of an object by its volume. This is:
ρ = m/V
ρ = 4.05 g / 12 mL
ρ = 0.3375 g/mL
<h3>
ρ ≅ 0.338 g/mL</h3>
OPTION A
0.29 m/s (wave velocity = wavelength (lamda)/period (T) in metres)
35 / 1.2 = 29.16
29.16 ÷ 100 = 0.29
Wave velocity in string:
The properties of the medium affect the wave's velocity in a string. For instance, if a thin guitar string is vibrated while a thick rope is not, the guitar string's waves will move more quickly. As a result, the linear densities of the two strings affect the string's velocity. Linear density is defined as the mass per unit length.
Instead of the sinusoidal wave, a single symmetrical pulse is taken into consideration in order to comprehend how the linear mass density and tension will affect the wave's speed on the string.

Answer:
it can cause huricans and flooding
Explanation:
Storm surge is the rising of the sea level due to the low pressure, high winds, and high waves associated with a hurricane as it makes landfall. The storm surge can cause significant flooding and cost people their lives if they're caught unexpected
