Answer:
Cheetah cubs are in danger from predators like lions and hyenas which can track their prey by scent and so the mother and her cubs leave an area when their scent is too strong so that they are not hunted and the cubs survive.
Mother Cheetahs also train their cubs to hunt so that they may get food for themselves which will ensure their survival as well thus showing that both of these practices can impact on reproductive success.
The heating curve is a representation of temperature change for a body with time as shown on cartesian axes.
<h3>What is a heating curve?</h3>
The heating curve is a representation of temperature change for a body with time as shown on cartesian axes.
The point A represents the steady increase in the temperature of the solid. The point B shows the point of fusion, at this point, the solid is transformed into liquid. The point C shows the temperature rise with time as the liquid is heated. The point D shows the process of vaporization which converts the liquid to gas. The point E shows when the substance now exists in the gas phase.

Answer:
clockwise torque is due to weight of the person + weight of the ladder
Explanation:
As we know that the forces that act on the ladder is given as
1) friction force
2) Normal force at the ends of the ladder
3) Weight of the person standing on the ladder
4) Weight of the ladder
So here we know that our reference point is at the bottom position of the ladder
So we will have
Torque due to weight of the person and weight of the ladder is counter balanced by the torque due to normal force and torque due to friction force
So here we have
clockwise torque is due to weight of the person + weight of the ladder
Answer:
d sin tea = m λ
Explanation:
When we have a two-slit system, the optical path difference determines whether the intensity reaching an observation screen is maximum or zero.
To find this difference in optical path, we assume that the screen is much farther than the gap is, we draw a perpendicular from ray 1 to the second ray
OP = d sin θ
now to have constructive interference and see a bright line this leg must be an integer number of wavelengths, ose
d sin tea = m λ
where
d is the distance between the two slits
θ complexion the angle sea the point hold it between the two slits
λ the wavelength of the coherent light used
m an integer, which counts the number of lines of interference
Units in the SI system
d, lam in meters
θ degrees
m an integer
Answer:
Soldering is a technique or a process to bond metals with the help of solder. Solder is a metal alloy with a low melting point and is often regarded as the base metal for soldering. The piece or structure that is being bonded together does not get hot enough to melt and this is where solder (base metal) comes into play and creates the connection.
