According to my research I found questions with the same info with option choices and they are:

A.) How many people in the study had the flu?
 B.)  How many people were included in the study?
 C.) What was the average age of the people in the study?
 D.)  What was the most common occupation of people in the study?

Among those options the answer would be the second choice B)

B.) How many people were included in the study?

This is the best answer, as the more people there is, a greater variety of choices is possible, leading to a better result that can usually apply to a larger population.

hope this helps

M A spherical conductor has a radius of 14.0cm and a charge of 26.0σC . Calculate the electric field and the electric potential
Yuri [45]

The Electric field is E=23400 V/m.

What is electric potential ?

The amount of labor required to convey a unit of electric charge from a reference point to a given place in an electric field is known as the electric potential (also known as the electric field potential, potential drop, or the electrostatic potential). More specifically, it is the energy per unit charge for a test charge that is negligibly disruptive to the field under discussion.

The electric field of a spherical conductor is given by:

{\displaystyle E={\frac {Q}{4\pi \varepsilon _{0}\,r^{2}}}

Here 'E' is the electric field and 'Q' is the electric charge.

therefore putting the values we get,

E=23400 V/m

Two asteroids in outer space collide and stick together. The mass of each asteroid, and the velocity of each asteroid before the
Alekssandra [29.7K]

Answer:

(5) It depends on whether the collision was elastic or inelastic.

Explanation:

Due to the absence of external forces and the fact that masses and initial velocities are known, it is needed to determine if collision is elastic or inelastic. If collision is inelastic, the Momentum Principle is sufficient to calculate final momentum, but if it is elastic, the Momentum Principle should be complemented with the application of the Energy Principle.

Hence, the correct answer is (5).

To understand the photoelectric effect physiciests should view light as having what type of properties?
fenix001 [56]

Answer:

Particle

Explanation:

To understand photoelectric effect the physicists has to view light as a particle and not wave. The wave nature of the light could not explain the phenomenon of photoelectric effect.

Photoelectric effect is emission of electrons from a material when electromagnetic radiation(Light) is incident on it. These emitted electrons are called photoelectrons.

The explain this effect Einstein proposed that beam of light is can not be a wave propagating through space, but a swarm of discrete energy packets, called as photons.
