It has a body that can handle the temperature around it. For example, Cold-blooded animals like snakes and lizards, are ectotherms who can regulate their body temperatures to the surrounding area.
Answer:
The atomic number of a nucleus will go down by two in alpha decay
Answer:
In a convergent plate boundary, when the heavier lithospheric plate subducts below the less denser one, it eventually gets heated up when reaches into the deeper zone. Due to this high heating of the plate, the water present in the minerals and rocks of the subducting plate is released and it gradually mixes up with the hot molten rocks.
This eventually leads to partial melting of hot rocks, altering its actual composition, and also causes volcanism when the less denser magma rises upward towards the surface. In addition to this, it can also causes changes in the geothermal gradient in that particular place.
Haha... no,
ferromagnetism is a substance with a high/natural susceptibility to magnetization. So those are your earth metals exhibiting unique magnetic behavior like iron, cobalt, and nickel.
Paramagnetism is when certain materials are weakly attracted by an external magnetic field, producing their own induced magnetic fields, aluminum is an example
Diamagnetism is when to magnetic things approach each other and there are repelling due to their electrons orbiting in opposite directions.
This problem can be solved based on the rule of energy conservation, as the energy of the photon covers both the energy needed to overcome the binding energy as well as the energy of ejection.
The rule can be written as follows:
energy of photon = binding energy + kinetic energy of ejectection
(hc) / lambda = E + 0.5 x m x v^2 where:
h is plank's constant = 6.63 x 10^-34 m^2 kg / s
c is the speed of light = 3 x 10^8 m/sec
lambda is the wavelength = 310 nm
E is the required binding energy
m is the mass of photon = 9.11 x 10^-31 kg
v is the velocity = 3.45 x 10^5 m/s
So, as you can see, all the parameters in the equation are given except for E. Substitute to get the required E as follows:
(6.63x10^-34x3x10^8)/(310x10^-9) = E + 0.5(9.11 x 10^-31)(3.45x10^5)^2
E = 6.41 x 10^-16 joule
To get the E in ev, just divide the value in joules by 1.6 x 10^-19
E = 4.009 ev
