Answer:
X = 5.48 mm
Explanation:
for single slit
By Rayleigh criterian
where d = slit width =0.5 mm
wavelength
therefore maximum of value of X can be calculated from above
X = 5.48 mm

<u>Answer</u>:
<em>Dog drinking water after it feels thirsty is an example of an organism responding to its internal environment to maintain homeostasis.
</em>
<u>Explanation</u>:
The regulation of temperature of the body of an organism is called homeostasis. <em>Warm blooded organisms depend on their internal environment to maintain homeostasis while cold blooded organisms</em> completely depend on their external environment to maintain homeostasis.
The <em>body temperatures of warm blooded organisms maintain its constancy despite changing temperature of the external environment</em>. But the case of cold blooded organisms is different.
Their body temperature completely depends on the external environment and thus they have<em> several behavioral and physiological adaptations to maintain their body temperatures </em>at the comfortable level.
<em>In this example dog is a warm blooded animal and it drinks water to maintain homeostasis since water helps in thermal regulation of its body.

Answer:
a = 1 m/s² and
Explanation:
The first two parts can be seen in attachment
We use Newton's second law on each axis
Y axis
Ty - W = 0
Ty = w
X axis
Tx = m a
With trigonometry we find the components of tension
Sin θ = Ty / T
Ty = T sin θ
Cos θ = Tx / T
Tx = T cos θ
We calculate the acceleration with kinematics
Vf = Vo + a t
a = (Vf -Vo) / t
a = (20 -10) / 10
a = 1 m/s²
We substitute in Newton's equations
T Sin θ = mg
T cos θ = ma
We divide the two equations
Tan θ = g / a
θ = tan⁻¹ (g / a)
θ = tan⁻¹ (9.8 / 1)
θ = 84º
We see that in the expression of the angle the mass does not appear therefore you should not change the angle
Answer:
average and instant
Explanation:
The average speed is the ratio of the <u>total path traveled and the time it took to travel that path</u>, that is why the first space must be average speed, this because it takes into account the total amount of distance, and the total amount of time.
Instant speed, is the speed an objet (in this case a car) has in <u>a particular moment in time</u>, for this speed it doesn't matter the distance or the time that the car has traveled, it only matters the speed in that moment, that is what the speedometer measures, thus the second blank space must be instant speed.
