The wavelengths of terrestrial radiation from earth's surface are concentrated in thermal infrared spectrum.
<u>Explanation:</u>
The wavelengths used in thermal infrared are in the range of micrometer ranging from 8 to 15. Terrestrial radiation is defined as the radiation that is originating from earth due to radioactive materials like uranium, thorium e.t.c.
Increase in terrestrial radiation by the use of radioactive materials will consequently increase global warming as it releases green house gases thereby degrading the quality of earth's atmosphere.
Answer:
force is 96 N
Explanation:
given data
mass = 40 kg
acceleration = 2.4 m/s²
to find out
force
solution
we know force is mass time acceleration so
we will apply here force formula that is express as
force = m × a ..............1
here m is mass and a is acceleration so
put here value in equation 1 we get force
force = 40 × 2.4
force = 96
so force will be 96 N
Force. Force is measured by newtons, probably because he came up with the equations to calculate force.
Hope this helps!
Answer:
If an object has more protons than electron then the net charge on the object is positive but if it has more electrons than protons the net charge on the object is negative. The object is electrically neutral if the number of protons is equal to the number of electrons.
Explanation:
Atom is composed of different subatomic particles . The 3 major subatomic particles are proton , neutron and electrons. The proton and the neutron is concentrated in the nucleus of an atom. The nucleus forms the dense core of an atom. The protons are positively charged while the electrons are negatively charged .The neutrons are neutrally charged. The electrons forms a cloud around the nucleus of an atom.
The net charge is defined as sum of the charges on an object. The 2 electric charges available are positive or negative charges. The proton are positive while the electron are negative. Although the mass of the proton is greater than the electron but the magnitude of their charges are equal . If an object has more protons than electron then the net charge on the object is positive but if it has more electrons than protons the net charge on the object is negative. The object is electrically neutral if the number of protons is equal to the number of electrons.
