Why should antibiotics be given to a person who is ill with a bacterial disease like strep throat, but NOT to a person who has a

viral disease like measles?
Antibiotics kill bacteria but not viruses.

Antibiotics make viruses grow faster.

Antibiotics are made by viruses.

Viruses are not living things.

If you guys dont mind can you please help me with this one

Antibiotics only kill bacteria, not viruses. Therefore, the answer is A.

When you get the common cold, you can't take antibiotics to be cured. The common cold is a virus.

A 6 kilogram block in outer space is moving at -100 m/s (to the left). It suddenly experiences three forces as shown below (in t
Blizzard [7]

Answer:

x = 1474.9 [m]

Explanation:

To solve this problem we must use Newton's second law, which tells us that the sum of forces must be equal to the product of mass by acceleration.

We must understand that when forces are applied on the body, they tend to slow the body down to stop it.

So as the body continues to move to the left, it is slowing down. Therefore we must calculate this deceleration value using Newton's second law. We must perform a sum of forces on the x-axis equal to the product of mass by acceleration. With leftward movement as negative and rightward forces as positive.

ΣF = m*a

10 +12*sin(60)= - 6*a\\a = - 3.39[m/s^{2}]

Now using the following equation of kinematics, we can calculate the distance of the block, before stopping completely. The initial speed must be 100 [m/s].

v_{f}^{2} =v_{o}^{2}-2*a*x

where:

Vf = final velocity = 0 (the block stops)

Vo = initial velocity = 100 [m/s]

a = - 3.39 [m/s²]

x = displacement [m]

0 = 100^{2}-2*3.39*x\\x=\frac{10000}{2*3.39}\\x=1474.9[m]

Ifa truck starts from rest and it has acceleration of 4 m/s for 5 second
yan [13]

Answer:

Distance 50m

final velocity 20ms^-1

s = ut +  \frac{1}{2} a {t}^{2}  \\  = 0 \times t +  \frac{1}{2} \times 4 \times  {5}^{2}   = 50m

v = u + at \\ v = 0 + 4 \times 5 \\ v = 20ms^{ - 1}
