Answer : The correct option is, (1) The lower the group number, the lower the period numbers, so the metalloids are found in a diagonal moving down from left to right.

Explanation :

Metalloids : These are the elements which shows both the property of metals and non-metals that means the metalloids are present in between the metals and non- metals elements.

Boron, silicon, germanium, arsenic, antimony, tellurium and polonium are the metalloids.

In the periodic table, the metals are present on the left side, non-metals are present on the right side and the metalloids are present between the metals and non-metals.

The relation between the group number and the period number is :

The lower the group number, the lower the period numbers. So, the metalloids are found in a diagonal moving down from left to right.

Hence, the correct option is, (1)

The periodic table is also shown below.

Im guessing it's (a) since the numbers go in chronological order and you read the periodic table left to right

Suppose a blood vessel's radius is decreased to 87% of its original value by plaque deposits and the body compensates by increas
dexar [7]

Answer:

The pressure difference will increase by the factor of 1.75

Explanation:

For constant flow rate, coefficient of viscosity, length of the vessel and the pressure difference is inversely proportional to the fourth power of the radius of the blood vessel

Apply the principle of Poiseuille’s law.

Q = (P2 - P1)/R

Pls check the attached file for step by step solution of the question. It is submitted in this way as typing the equation may not be explanatory.

Which band of the electromagnetic spectrum has the lowest frequency
Murrr4er [49]

Answer:

Radio waves

Explanation:

Electromagnetic waves are produced by the oscillations of electric and magnetic field. They are transverse waves, which means that the oscillations occur in a direction perpendicular to the direction of propagation of the wave, and they are the only type of waves that can travel through a vacuum.

Electromagnetic waves are classified into 7 different types, depending on their frequencies. From lowest to highest frequencies, we have:

Radio waves

Microwaves

Infrared

Visible light

Ultraviolet

X-rays

Gamma rays

Radio waves are the electromagnetic waves with lowest frequency. They are used, for examples, for satellites, telecommunication, broadcasting.

90cm uniform lever has a load 30N suspended at 15cm from one of it's end. If the fulcrum is at the center of gravity. The force
solniwko [45]

Answer: F = 20 N

Explanation:

I will ASSUME that the fulcrum is at the center of gravity of the lever arm, This means that the lever arm itself creates no moment about the fulcrum because there is no moment arm for that particular force.

To solve, we sum moments about any convenient point to zero (zero because there is no acceleration in the F = ma equation)

The easiest convenient point is the fulcrum

30((90/2) - 15) - F(90/2) = 0

           30(30) = F(45)

                    F = 900/45 = 20 N
