Answer:

C.consider that there was an error during measuring and collect further data

Explanation:

Some branches of biology, when work requires intense contact with bacteria, use a technique known as “bacterial culture”. The technique is used as a catalyst, and aims to improve the performance of the processes involved. The bacterial culture technique basically consists of promoting the multiplication of colonies of microbial organisms in vitro. Bacteria colonies are genetically similar organisms, so it is likely that the colonies cells will have very similar sizes. Accordingly, in the case presented in the question, we can consider that there was an error during the measurement and that more data should be collected.

The scientists should best deal with this measurement by stating that there was an error during measuring and collect further data.

Two photographers are competing for business in town. Andrea uses only film photography and Keira uses only digital photography.

____ [38]

There is no right or wrong answer, your teacher wants you to support your own answer with points. As long as the reasons make logical sense you are fine.

I think they both have valid points. Their replies are both true, but from a buyer's perspective who would you purchase services from? You would get different answers depending on who you ask.

If you choose to go old school, obviously you get an actual photo that can be stored physically. This means it is a memory that can be preserved, and it might feel more nostalgic being able to touch the photo.

On the other hand, a digitally stored photo can be altered (photoshop), but it is forever as long as the internet still exists. A physical photo would fade with time, which doesn't happen with a digital photo.

It is definitely easier to argue that digital photography has more advantages (they do, it is why nobody uses film anymore)

Points you can consider:

Can be transferred to the other side of the world instantly

Ability to make copies and print as many photos as you want

Can be stored on cloud/devices and be like that forever

Compare them with film photography to give a more solid response.

A golf ball with m = 46 g is struck a blow which makes an angle of 45o with the horizontal. The drive lands 200 m away on a flat

AfilCa [17]

Answer:

Average force will be equal to 2908.57 N

Explanation:

We have given mass of the ball m = 46 gram = 0.046 kg

Let velocity at which ball is projected is u m/sec

Angle at which ball is projected $\Theta =45^{\circ}$

Range of the ball is given R = 200 m

Range is equal to $R=\frac{u^2sin2\Theta }{g}$

$200=\frac{u^2sin(90^{\circ})}{9.8}$

$u^2=1960$

u = 44.27 m/sec

Change in momentum of the ball is equal to $P=mu=0.46\times 44.27=20.36kgm/sec$

Time of impact is given $dt=7ms=0.007sec$

Force is equal to rate of change of momentum

So force $F=\frac{dP}{dt}=\frac{20.36}{0.007}=2908.57N$

Force will be equal to 2908.57 N
