Answer:
Force
Explanation:
The mass of an object is the quantity of matter it contains. It is measured in kilograms.
Acceleration is the ratio of the change in the velocity of an object to the change in time. It is measured in m/.
When the mass of an object is multiplied with its acceleration, this gives the average force applied on the object. As force is defined as agent that can change the state of an object.
i.e F = m × a
where F is the force, m is the mass of the object and a its acceleration.
The two major classes of force are; contact force and field force.
The Nucleus contains Protons and Neutrons.
The Neutrons does not have a charge.
The Protons are positively charge.
Hence the charge on the Nucleus, would be the charge of the proton, which is positive.
Hence Nucleus is Positively Charged.
The speed of the wave is C) 8m/s.
<h3>What is speed?</h3>
It should be noted that speed simply means the distance that's covered at a particular time period.
It should be noted that the distance was illustrated as 2m and the frequency is given as 4Hz. Therefore, the speed will be calculated as:
Speed = Frequency × Wavelength
= 2 × 4
= 8m/s
Therefore, the speed is 8m/s.
