Explanation:
An object in FREE-FALL on the MOON would experience only acceleration
Answer:
Explanation:
m = Mass of ball = 150 g
= Angle of kick =
= Displacement of ball in x direction = 12 m
Range of projectile is given by
The velocity of the ball instantly after the man kicks the ball is
Impulse is given by
The impulse of his foot on the ball is .
The best use of an atomic model to explain the charge of the particles in Thomson's beams is:
<u>An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to remove.</u>
<u>Explanation:</u>
In Thomson's model, an atom comprises of electrons that are surrounded by a group of positive particles to equal the electron's negative particles, like negatively charged “plums” that are surrounded by positively charged “pudding”.
Atoms are composed of a nucleus that consists of protons and neutrons . Electron was discovered by Sir J.J.Thomson. Atoms are neutral overall, therefore in Thomson’s ‘plum pudding model’:
-
atoms are spheres of positive charge
- electrons are dotted around inside
Thomson's conclusions made him to propose the Rutherford model of the atom where the atom had a concentrated nucleus of positive charge and also large mass.
Intensity of wave is defined as the work per unit area and it is calculated through the equation,
I = P / A
If a person moved farther from the light source, the area covered by the light. With the equation, A is a inversely proportional to light. If the distance is to cover half of the team. The answer therefore, the intensity of the wave is lessened.
