Copernicus's model states that the sun is in the center, and that the planets move around it in a circle. Kepler's first law of planetary motion says that they move around the sun in an ellipse.
The force the horse and the rider exerts on the wall is equal to the weight combined acting in the opposite direction:
<h3>Force</h3>
Given Data
- mass of horse and rider = 575kg
- Force acting on wall = ??
When a body of mass rests on a surface, it exerts a force equal to the weight of the mass but opposite in direct on the mass/object
hence the force is computed as
Force = mass * acceleration
Force = 575 * 9.81
Force = 5640.75N

Answer:
B
Explanation:
Atomic structure contains electrons, protons and neutrons.
Electron is very light compared to proton and neutrons.
Given that the mass of an electron is
A) equal to the mass of a proton
B) less than the mass of a neutron
C) greater than the mass of a proton
D) equal to the mass of a neutron
The correct answer is B which is less than the mass of the neurons.

Determine the frequency of a clock waveform whose period is 2us or (micro) and 0.75ms
frequency (f)=1/( Time period).
Frequency of 2 us clock =1/2*10^-6 =10^6/2 =500000Hz =500 kHz.
Frequency of 0..75ms clock =1/0.75*10^-3 =10^3/0.75 =1333.33Hz =1.33kHz.
Kate's recollection of these different events along her life best exemplifies the use of her episodic memory.
<h3>What is episodic memory?</h3>
The term episodic memory makes reference to conscious personal background experiences that were collected along life.
Episodic memory is also defined as the collection of all life-day experiences collected by a person.
The episodic memory may be, for example, the first day when a person drove his/her car or a bike.
