Urgent Important!!
Many medications have a warning to avoid driving because.
A. they haven't been scientifically tested yet.
B. they have been proven to cause drowsiness.
C. they want to cover all their bases.
Answer:
B) they have been proven to cause drowsiness
Explanation:
B is the only answer that makes sense, as the other answers do not make sense. All medications are scientifically tested before they can be used by someone. Covering their bases would show negligence and is bad.
Hope this helps!

A mechanical wave travels through empty space, while an electromagnetic wave travels through matter.
A mechanical wave has a short wavelength, while all electromagnetic waves have long wavelengths.
A mechanical wave has a high frequency, while all electromagnetic waves have low frequencies.
A mechanical wave travels through matter, while an electromagnetic wave travels through empty space.
its regular chooiseing just decide one and tell me
Answer: A a mechanical wave travels through empty space, while an electromagnetic wave travels through matter.
Explanation: A mechanical wave travels through empty space, while an electromagnetic wave travels through matter. A mechanical wave has a short wavelength, while all electromagnetic waves have long wavelengths.
DEFINE SIGNIFICANT DIGITS.
Answer:
Significant figures are the number of digits in a value, often a measurement, that contribute to the degree of accuracy of the value. We start counting significant figures at the first non-zero digit. Calculate the number of significant figures for an assortment of numbers.
Explanation:
any of the digits of a number beginning with the digit farthest to the left that is not zero and ending with the last digit farthest to the right that is either not zero or that is a zero but is considered to be exact. — called also significant figure.
A car engine has power than a horse because a car engine does the same amount of work in time. Yasmin and Raj each had 10 boxes of equal weight to stack next to each other on the same shelf, at the same height and in the same arrangement. Yasmin completed the task in 2 minutes, while Raj took 3 minutes to stack his boxes. Raj applied power than Yasmin because his stacking took time to do the same amount of work.
Answer:
A car engine has more power than a horse because a car engine does the same amount of work in time. Yasmin and Raj each had 10 boxes of equal weight to stack next to each other on the same shelf, at the same height and in the same arrangement. Yasmin completed the task in 2 minutes, while Raj took 3 minutes to stack his boxes. Raj applied less power than Yasmin because his stacking took more time to do the same amount of work.
Explanation:
A car engine has more power than a horse because a car engine does the same amount of work in less time. Raj applied less power than Yasmin because his stacking took more time to do the same amount of work.
What is power?The quantity of energy moved or converted per unit of time is known as power in physics. The watt, or one joule per second, is the unit of power in the International System of Units. Power is also referred to as activity in ancient writings. A scalar quantity is power.
Energy divided by time represents the dimension of power. The watt (W), which equates to one joule per second, is the unit of power in the International System of Units (SI).
Another popular unit of measurement is horsepower (hp), which is equivalent to a horse's power; one mechanical horsepower is equal to around 745.7 watts.

Which of the following is true about myelin?
It inhibits neural communication.
O It cannot be affected by illness.
It is covered by axons.
It's a fatty insulation.
It slows down neuronal operations.
Answer:
It's a fatty insulation.
Explanation:
"Myelin" is a fatty substance which insulates the axons of the nerve cells. Therefore, it covers the axons. This makes choice A correct and choice C incorrect.
This allows faster neural communication or hastens the transmission of signals between neurons. This makes choice A incorrect and choice E incorrect. It doesn't inhibit neural communication nor does it slow down neuronal operation; rather, it increases both speed.
Myelin can be affected by illness. An example of this is the disease called "Multiple Sclerosis," which targets the myelin sheath.
Ifa truck starts from rest and it has acceleration of 4 m/s for 5 second
calculate its final velocity. What will be the distance travelled by the track
during the time interval?
Answer:
Distance 50m
final velocity 20ms^-1
[tex]s = ut + \frac{1}{2} a {t}^{2} \\ = 0 \times t + \frac{1}{2} \times 4 \times {5}^{2} = 50m[/tex]
[tex]v = u + at \\ v = 0 + 4 \times 5 \\ v = 20ms^{ - 1} [/tex]

When you drop a 0.38 kg apple, Earth exerts
a force on it that accelerates it at 9.8 m/s’ to-
Ward the earth's surface. According to New-
ton's third law, the apple must
exert an equal but opposite force on earth. If the mass of the Earth is 5.98 x 10^24 kg, what is the magnitude of the Earth’s acceleration towards the apple? Answer in units or m/s^2
Answer:
6.2 ×10^-25
Explanation:
Ma = mg
a = (m/M)g
[tex]a = \frac{0.38}{5.98 \times {10}^{24} } \times 9.8 = 6.2 \times {10}^{ - 25} [/tex]
