Answer:
The density is 1.3 kg per cubic meter
Explanation:
Density is mass divided by volume, so:
8.5-2 = mass of paint (kg)
5 = volume (L)
P = 6.5/5
Answer:
option B
Explanation:
The correct answer is option B
Effective capacity is the capacity of a firm to achieve the given target will all the constraints .
Effective capacity of an company can be calculated by actual capacity divided by the efficiency of the company.
it can be explained by an example
Assume the capacity of company to produce toy is 49 per hours and the efficiency of the production is 70 %
so the effective capacity will be equal to 49/0.7 = 70
hence, effective capacity will be 70
Answer:
P = 2.91*10^{-24} kg m/s
size of atom hat lie in range of 1 to 5 Angstrom
Angstrom
Explanation:
A) MOMENTUM
p = mv
where m is mass of electron
so momentum p can be calculated as
p = 9.11*10^{-31} *3.2*10^{6}
P = 2.91*10^{-24} kg m/s
b) wavelength
where h is plank constant
so
c) size of atom hat lie in range of 1 to 5 Angstrom
d) from the information given in the question we have
we know that
[]
Angstrom
Answer:
0.4344A
Explanation:
From Ampere's law, it can be shown that the magnetic field B inside a long solenoid is
Where
B= Magnetic field strenght at distance d
I= current
Permeability of free space ()
N= Number of loops
Our values are defined as follow,
T
As a current required to become 104 times the Earth's magnetic field is required, we use B '
<em>Therefore is needed 0.4344A in the solenoid to produce a magnetic field inside the solenoid, near its center, that is 104 times the Earth's magnetic field.</em>
The answer is 37 cause the two sides squared and added together equals the hypotenuse squared after that you just find the square root of the answer
