Answer:Well it depends on what the heavy load is but it is mostly easy to do it with a crowbar because it gives you leverage and it is stronger.
Explanation:
Your welcome I think.
Energy of electron in atom level n =
When n = 4
When n = 5
Energy of photon absorbed = -0.544 - (-0.85) = 0.306 eV = 0.489 * J
We also have energy of photon =
Comparing both
So, Energy of photon = 4069 nm
Answer:
The net charges on inner surface is +3 C
The net charges on outer surface is +7 C
Explanation:
Given that,
Charge on spherical conducting shell = 10 C
Charge at center = -3 C
We know that,
The net electric field inside the conducting shell is zero. The Gaussian surface inside the conductor must have zero net charge.
We need to calculate the net charges on inner surface
The charge on the inner surface of the conductor must be equal and opposite to the present charge of the center.
So, The net charges on inner surface is +3 C.
We need to calculate the net charges on outer surface
Using formula of net charge
Put the value into the formula
Hence, The net charges on inner surface is +3 C
The net charges on outer surface is +7 C
Answer:
See below
Explanation:
The units in this question need to be all the same
Volume = L x W x H where 'H' is thickness of the foil
1.10 kg = 1100 g
The volume given = mass / density = 1100 g / 2.70 g/cm^3= 407.407 cm^3
304 mm = 30.4 cm .016 mm = .0016 cm
LWH = L * 30.4 cm * .0016 cm = 407.407 cm^3
<u>L = 8375.97 cm = 83.76 meters</u>
