Answer: electronegativity

Explanation:

Electronegativity is defined as the property of an element to attract a shared pair of electron towards itself.

The size of an atom decreases as we move across the period because the electrons get added to the same shell and the nuclear charge keeps on increasing. Thus the electrons get more tightly held by the nucleus.

As, the size of an element decreases, the valence electrons come near to the nucleus. So, the attraction between the nucleus and the shared pair of electrons increases and thus the electronegativity increases.

Two radio antennas A and B radiate in phase. Antenna B is a distance of 120 m to the right of antenna A. Consider point Q along

LuckyWell [14K]

Answer:

240 m

120 m

Explanation:

d = Path difference = 120 m

For destructive interference

Path difference

$d=\dfrac{\lambda}{2}\\\Rightarrow \lambda=2d\\\Rightarrow \lambda=2\times 120\\\Rightarrow \lambda=240\ m$

The longest wavelength is 240 m

For constructive interference

$d=\lambda\\\Rightarrow 120\ m=\lambda$

The longest wavelength is 120 m

A snowboarder is sliding back and forth on a half pipe at one point she leaves the top of the half pipe and slides to the other

r-ruslan [8.4K]

Answer:

he kinetic energy increases on the descent, being maximum at the lowest point of the trajectory.

Explanation:

In these semicircular sections the skaters slide from one side to the other, in the downward path their kinetic energy increases and their potential energy decreases; When it leaves the ramp and is in the air, the kinetic energy decreases rapidly, up to the point of maximum height where the kinetic energy is zero.

Consequently, the kinetic energy increases on the descent, being maximum at the lowest point of the trajectory.

Equal in number to the number of protons

Lelechka [254]

Answer:

atomic number (Z)

Explanation:

The atomic number (Z) is equal to the number of protons in the nucleus. In a neutral atom, the number of protons is equal to the number of electrons. The mass number of an atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.

Nerve impulses in a human body travel at a speed of about 100 m/s. Suppose a man accidentally stubs his toe. About how much time

alexandr1967 [171]

Answer:

t = 0.018 s

Explanation:

given,

nerve impulse in human body travel at a speed of = 100 m/s

height of the man = 1.80 m

time taken by the impulse to travel from foot to brain = ?

distance = speed × time

1.80 = 100 × t

t = $\dfrac{1.80}{100}$

t = 0.018 s

hence, the time taken by the nerve to reach brain from toe is 0.018 s
