Answer:
Not all of the time, it can also depend on the strength of the magnet.
Explanation:
say you have a small very strong magnet, that might work just as well as a large but week magnet.
Explanation:
Hi there!
Mass of the container (m) = 15000 kg
Also from the figure;
Volume of the container (V) = l*b*h
{ From figure length = 2m , breadth = 1.1m, height = 2.5m}
So,
V = (2*1.1*2.5) m³
= 5.5m³
Then;
Density (d) = m/v
= 15000/5.5
= 2727.27 kgm³
Therefore, the density is 2727.27 kgm³.
Hope it helps!
Answer:
The energy of each photon in the light beam is 
.
Explanation:
Given that,
Index of refraction of glass =1.55
Index of refraction of material =1.30
Wavelength = 115 nm
We need to calculate the energy of each photon in the light beam
Using formula of energy
Where, h = Planck constant
=wavelength
c = speed of light
Put the value into formula
Hence, The energy of each photon in the light beam is .
Answer:
The block solar winds and other harmful things
Explanation:
The Earth's magnetic field serves to deflect most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation.
The focus of Lesson 1 is Newton's first law of motion - sometimes referred to as the law of inertia. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Hope this helps :)
