Newton's 3rd law:
Every action has an equal and opposite reaction.
When you apply force on an object, there is an equal force applied on you from that object.

Answer: Heat transfer by radiation</h2>
Explanation:
There are three ways in which the thermal transfer (heat) occurs:
1. By Conduction, when the transmission is by the <u>direct contact.</u>
2. By Convection, heat transfer<u> in fluids</u> (like water or the air, for example).
3. By <u>Radiation</u>, by the electromagnetic waves (they can travel through any medium and in vacumm or empty space)
Since outter space is vacuum (sometimes called "empty"), energy cannot be transmitted by convection, nor conduction. It must be transmitted by electromagnetic waves that are able to travel with or without a medium.
Answer: No
Can the change in cyclin concentration during mitosis be explained by the fact that the cell divides in two and thus divides the material in the cell into two smaller volumes?
Explanation: The cyclin concentration is not halved but degraded during mitosis.
There is an increase in cyclin concentrations at interphase. These changes are caused by the presence of Cyclin Dependent Kinase (CDK) complexes. CDK being a substrate of cyclin catalyses cyclin, thereby increasing its concentration. During mitosis, cyclins are destroyed, signifying the end of mitosis and cytokinesis.
Without this process, it will be impossible for the cell to exit mitosis.
Answer:
D. 30m/s
Explanation:
According to the equation of motion
v=u +at
v = Final velocity
u = initial velocity
a = acceleration
t = time taken
Since we don't know the acceleration of the body, we will find its acceleration using newtons first law of motion F = ma
10000 =2000a
a = 5m/s²
initial velocity = 0m/s since the body starts from rest
v is what we are looking for
t = 6seconds
Substituting this datas in the formula
v = 0+ 5(6)
v = 30m/s (D)
