I believe the correct answer is the third option. One advantage of using lasers in cutting patterns instead of traditional cutting machines would be that lasers save time by cutting through more layers of fabric. Although it would cost some energy and the initial cost would be high, you would still be able to save some money as time goes by since you will be able to produce more for a certain period of time as compared to using traditional cutting methods for the same period of time. Also, by using lasers, you can cut complex patterns easily and you will need less people in the production.
Explanation:
use the diagram^
horizontal velocity of the object nvr changes, it'll stay 50m/s till it hits the ground
initial vertical velocity = 0
to find the final vertical velocity, use the formula:
where u = 0m/s, a = 9.8m/s², and s = 2000m
solve for v.
for time taken to reach ground, use the formula:
where v = the value for v u calculated above, u = 0 m/s, a = 9.8m/s² and solve for t.
Answer:
46.15m/s
Explanation:
We are given that
Initial speed,u=38 m/s
Height of cliff,h=70 m
We have to find the speed with which the cycle strikes the ground at a height 35 m on the other side.
h'=35 m
Using conservation law of energy
Where 
Substitute the values
Of the following given choices;
A. A higher fertility rate
B. Less access to medicine
C. A new source of fresh water
D. A higher birthrate
The answer is; C
Carrying capacity is the maximum population size than habitat or environment can sustain indefinitely because it is able to replenish its resources. Limiting factors to carrying capacity of an ecosystem include resources such as food, water, and space.
Wave speed = frequency * wavelength
We need to rearrange this equation because we are finding the wavelength :
Wavelength = wave speed / frequency
To rearrange it, I just divided it by frequency so that wavelength was the subject.
Now, input these numbers into this equation :
Wavelength = wave speed / frequency
Wavelength = 25 / 5
Wavelength = 5m
