Answer:
Yes.Explanation:
If we want to "disable" astham attacks, that would imply too many restictions for those people who can suffer from these attacks. For example, in order to avoid these attacks, they couldn't do sport activities, because that would alter their respiratory system, which occasionate astham attacks.
Therefore, this statement is true.

Which factors affect the speed of ocean waves?
Answer:
The speed of all ocean waves is controlled by gravity, wavelength, and water depth. Most characteristics of ocean waves depend on the relationship between their wavelength and water depth. Wavelength determines the size of the orbits of water molecules within a wave, but water depth determines the shape of the orbits

Find the acceleration of a car with the mass of 1,200 kg and a force of
11 x 103 N.
a
9.2 m/s2
b 5 m/s2
c 2 m/s
d 10 m/s2
Answer:9.17 m/s^2
Explanation:
mass=1200kg
Force=11 x 10^3 N
Acceleration=force ➗ mass
Acceleration=11 x 10^3 ➗ 1200
Acceleration=9.17
Acceleration=9.17 m/s^2
A neutral atom has the same number of electrons as it does neutrons.
O A. True
O B. False
Answer:
B
Explanation:
It is true that a neutral atom has the same number of electrons as it does neutrons.
The neutrons are neutral particles, whereas the electrons are negatively charged particles.
Instead of neutrons, a neutral atom has an equal number of protons and electrons. Because they have no charge, neutrons are electrically neutral particles. The negative charge of the electrons in the electron shells encircling the nucleus in a neutral atom balances the positive charge of the protons in the nucleus. In a neutral atom, the number of protons and electrons is therefore identical, but the number of neutrons is variable.
Hence, It is true that a neutral atom has the same number of electrons as it does neutrons.

Answer:
Force, [tex]F=2.88\times 10^{-3}\ N[/tex]
Explanation:
Charge 1, [tex]q_1=1\times 10^{-7}\ C[/tex]
Charge 2, [tex]q_2=-2\times 10^{-7}\ C[/tex]
Distance between charges, d = 0.25 m
It is required to find the force between charges. The charges are opposite the force between them is attractive. The force between charges is given by :
[tex]F=\dfrac{kq_1q_2}{d^2}\\\\F=\dfrac{9\times 10^9\times 1\times 10^{-7}\times 2\times 10^{-7}}{(0.25)^2}\\\\F=2.88\times 10^{-3}\ N[/tex]
So, the force between charges is [tex]2.88\times 10^{-3}\ N[/tex].
