Zebra coloration - the coloration makes it harder for predators to spot.
Answer:
Following are the solution to the given points:
Explanation:
For point a:
Find the schematic of the empty body and in attachment. Upon on ball during the pitch only two forces act:
The strength of the pitcher F is applied that operates horizontally. Its gravity force acting on an object is termed weight, which value is where m denotes mass, and g the acceleration of gravity.
For point b:
First, they must find that ball's acceleration. You can use the SUVAT equation to achieve that
where
Solving for a,
Calculating the mass:
Calculating the force:
For point c:
0.195 times the pitcher's weight
Solving for W:
Now the force of Part B could be defined as the fraction of the mass of the pitcher:
Answer:
Mia is correct, but did not show a lot of work.
Explanation:
Mia must explain her answer and give reasoning by using what knowledge she has on the subject.
The expression for the block's centripetal acceleration is derived as ω²r or v²/r.
<h3>
What is centripetal acceleration?</h3>
The centripetal acceleration of an object is the inward or radial acceleration of an object moving in a circular path.
The expression for the block's centripetal acceleration is derived as follows;
ω = dθ/dt
where;
- ω is the angular speed
- θ is the angular displacement
- t is the time of motion
ac = ω²r
where;
- r is the radius of the circular path
Also, ω = v/r
ac = (v/r)²r
ac = v²/r
Thus, the expression for the block's centripetal acceleration is derived as ω²r or v²/r.

Answer:
If both the maximum voltage and current are exceeded in a resistor, that the point will lie in the thermal breakdown of the resistor.
Explanation:
This indicated that there will be an abundance of free electrons which will be available freely. This abundance of the electrons in a conductor, will result in the reduction of the overall conductivity. whereas in an insulator or semiconductor this will enhance the overall conductivity.
As the point lies in the thermal breakdown, the Ohm's law is no longer valid and thus no analytical solution can be presented in this regard.
